This formula has been discontinued by the manufacturer and has been reformulated. The new formulation is still available under the same name.
This product contains 1,3-dimethylamylamine (DMAA), also known as methylhexanamine or geranium extract. There are serious safety concerns about DMAA. It is a stimulant that can potentially increase blood pressure and increase the risk of adverse cardiovascular events. DMAA-containing products have been linked to over 40 serious adverse event reports including adverse cardiovascular, metabolic, nervous system, and psychiatric events. Reports of death have also occurred (17660,17663,17904,17906,17907,17908,17958). In 2011, US Department of Defense (DoD) temporarily banned the sale of DMAA-containing supplements in military stores due to safety concerns. Sales of these products will be prohibited until the DoD investigates reports of potential serious adverse outcomes related to this product (17904,17909). On April 9, 2012, DMAA was also banned in New Zealand due to safety concerns (17960). Due to its stimulant effects, DMAA was added to the World Anti-Doping Agency's prohibited substances list for 2010. It is listed using the name methylhexaneamine on the prohibited list (17600).
Supplements that contain DMAA often list rose geranium oil, geranium oil, or geranium stems on the label. Some supplement manufacturers claim that this is because rose geranium oil contains a small amount of dimethylamylamine. However, this has not been verified by laboratory analysis. Some laboratories have not been able to detect dimethylamylamine in geranium oil. There is concern that some supplement manufacturers may be artificially spiking their supplements with this synthetic drug (17661,17662). In 2011, Health Canada determined that there is no credible evidence that DMAA is derived from the geranium plant. Therefore, DMAA is considered a drug and is not allowed in dietary supplements in Canada (17959).

LIKELY UNSAFE ...when used orally. 1,3-DMAA is a drug originally used as a stimulant nasal decongestant. There is concern that it increases the risk of serious adverse cardiovascular events, similar to other stimulants such as synephrine in bitter orange and ephedrine alkaloids from ephedra. There are several case reports linking 1,3-DMAA to serious adverse events including lactic acidosis, hemorrhagic stroke, heat stroke, and death (17599,17660,17662,17663,17904,94361,94369,94374). Although some supplement manufacturers claim that 1,3-DMAA is a natural compound found in geranium oil, this has not been verified by laboratory analysis. Some laboratories have not been able to detect 1,3-DMAA in geranium oil (94370,94372). There is concern that some supplement manufacturers may be artificially spiking their supplements with this synthetic drug (17661,17662). The New Zealand government restricted sales of supplements containing 1,3-DMAA to prevent the sale to people under 18 years of age due to concerns about safety (17599). The FDA has declared products containing 1,3-DMAA to be illegal and potential health risks (94383). Avoid using.

Insufficient reliable information available; avoid using in medicinal amounts.
LIKELY SAFE ...when used orally, parenterally, or rectally and appropriately. Caffeine has Generally Recognized As Safe (GRAS) status in the US (4912,98806). Caffeine is also an FDA-approved product and a component of several over-the-counter and prescription products (4912,11832). According to a review by Health Canada, and a subsequent large meta-analysis conducted in the US, doses of caffeine up to 400 mg daily are not associated with significant adverse cardiovascular, bone, behavioral, or reproductive effects in healthy adults (11733,98806). The US Dietary Guidelines Advisory Committee states that there is strong and consistent evidence that consumption of caffeine 400 mg daily is not associated with increased risk of major chronic diseases, such as cardiovascular disease or cancer, in healthy adults (98806). This amount of caffeine is similar to the amount of caffeine found in approximately 4 cups of coffee. Keep in mind that only the amount of ADDED caffeine must be stated on product labels. The amount of caffeine from caffeine-containing natural ingredients such as coffee or green tea does not need to be provided. This can make it difficult to determine the total amount of caffeine in a given product.
POSSIBLY UNSAFE ...when used orally, long-term or in high doses (91063). Chronic use, especially in large amounts, can produce tolerance, habituation, psychological dependence, and other adverse effects (3719). Acute use of high doses, typically above 400 mg daily, has been associated with significant adverse effects such as tachyarrhythmia and sleep disturbances (11832). Keep in mind that only the amount of ADDED caffeine must be stated on product labels. The amount of caffeine from caffeine-containing natural ingredients such as coffee or green tea does not need to be provided. This can make it difficult to determine the total amount of caffeine in a given product.
LIKELY UNSAFE ...when used orally in very high doses. The fatal acute oral dose of caffeine is estimated to be 10-14 grams (150-200 mg/kg). Serious toxicity can occur at lower doses depending on variables in caffeine sensitivity such as smoking, age, or prior caffeine use (11832,95700,97454,104573). Caffeine products sold to consumers in highly concentrated or pure formulations are considered to a serious health concern because these products have a risk of being used in very high doses. Concentrated liquid caffeine can contain about 2 grams of caffeine in a half cup. Powdered pure caffeine can contain about 3.2 grams of caffeine in one teaspoon. Powdered pure caffeine can be fatal in adults when used in doses of 2 tablespoons or less. As of 2018, these products are considered by the FDA to be unlawful when sold to consumers in bulk quantities (95700).
CHILDREN: POSSIBLY SAFE
when used orally or intravenously and appropriately in neonates under the guidance of a healthcare professional (6371,38340,38344,91084,91087,97452).
...when used orally in amounts commonly found in foods and beverages in children and adolescents (4912,11833,36555). Daily intake of caffeine in doses of less than 2.5 mg/kg daily are not associated with significant adverse effects in children and adolescents (11733,98806). Keep in mind that only the amount of ADDED caffeine must be stated on product labels. The amount of caffeine from caffeine-containing natural ingredients such as coffee or green tea does not need to be provided. This can make it difficult to determine the total amount of caffeine in a given product.
PREGNANCY: POSSIBLY SAFE
when used orally in amounts commonly found in foods.
Intakes of caffeine should be monitored during pregnancy. Caffeine crosses the human placenta, but is not considered a teratogen (38048,38252,91032). Fetal blood and tissue levels are similar to maternal concentrations (4260). The use of caffeine during pregnancy is controversial; however, moderate consumption has not been associated with clinically important adverse fetal effects (2708,2709,2710,2711,9606,16014,16015,98806,108814). In some studies consuming amounts over 200 mg daily is associated with a significantly increased risk of miscarriage (16014,37960). This increased risk seems to occur in those with genotypes that confer a slow rate of caffeine metabolism (98806). According to a review by Health Canada, and a subsequent large meta-analysis conducted in the US, up to 300 mg daily can be consumed during pregnancy without an increased risk of spontaneous abortion, stillbirth, preterm birth, fetal growth retardation, or congenital malformations (11733,98806). However, observational research in a Norwegian cohort found that caffeine consumption is associated with a 16% increased odds of the baby being born small for gestational age when compared with no consumption (100369,103707). The same Norwegian cohort found that low to moderate caffeine consumption during pregnancy is not associated with changes in neurodevelopment in children up to 8 years of age (103699). Advise patients to keep caffeine consumption below 300 mg daily during pregnancy. This is similar to the amount of caffeine in about 3 cups of coffee or tea.
PREGNANCY: POSSIBLY UNSAFE
when used orally in amounts over 300 mg daily.
Caffeine crosses the placenta, producing fetal blood concentrations similar to maternal levels (4260,98806). Consumption of caffeine in amounts over 300 mg daily is associated with a significantly increased risk of miscarriage in some studies (16014,98806). Advise patients to keep caffeine consumption below 300 mg daily during pregnancy. This is similar to the amount of caffeine in about 3 cups of coffee or tea. Additionally, high doses of caffeine throughout pregnancy have resulted in symptoms of caffeine withdrawal in newborn infants (9891). High doses of caffeine have also been associated with spontaneous abortion, premature delivery, and low birth weight (2709,2711,91033,91048,95949). In a cohort of mother/infant pairs with a median maternal plasma caffeine level of 168.5 ng/mL (range 29.5-650.5 ng/mL) during pregnancy, birth weights and lengths were lower in the 4th quartile of caffeine intake compared with the 1st. By age 7, heights and weights were lower by 1.5 cm and 1.1 kg respectively. In another cohort of mother/infant pairs with higher maternal pregnancy plasma caffeine levels, median 625.5 ng/mL (range 86.2 to 1994.7 ng/mL), heights at age 8 were 2.2 cm lower, but there was no difference in weights (109846).
LACTATION: POSSIBLY SAFE
when used orally in amounts commonly found in foods.
Caffeine intake should be closely monitored while breast-feeding. During lactation, breast milk concentrations of caffeine are thought to be approximately 50% of serum concentrations and caffeine peaks in breastmilk approximately 1-2 hours after consumption (23590).
LACTATION: POSSIBLY UNSAFE
when used orally in large amounts.
Caffeine is excreted slowly in infants and may accumulate. Caffeine can cause sleep disturbances, irritability, and increased bowel activity in breast-fed infants exposed to caffeine (2708,6026).
LIKELY SAFE ...when used orally or intravenously and appropriately. Calcium is safe when used in appropriate doses (7555,12928,12946,95817). However, excessive doses should be avoided. The Institute of Medicine sets the daily tolerable upper intake level (UL) for calcium according to age as follows: Age 0-6 months, 1000 mg; 6-12 months, 1500 mg; 1-8 years, 2500 mg; 9-18 years, 3000 mg; 19-50 years, 2500 mg; 51+ years, 2000 mg (17506). Doses over these levels can increase the risk of side effects such as kidney stone, hypercalciuria, hypercalcemia, and milk-alkali syndrome. There has also been concern that calcium intake may be associated with an increased risk of cardiovascular disease (CVD) and coronary heart disease (CHD), including myocardial infarction (MI). Some clinical research suggests that calcium intake, often in amounts over the recommended daily intake level of 1000-1300 mg daily for adults, is associated with an increased risk of CVD, CHD, and MI (16118,17482,91350,107233). However, these studies, particularly meta-analyses, have been criticized for excluding trials in which calcium was administered with vitamin D (94137). Many of these trials also only included postmenopausal females. Other analyses report conflicting results, and have not shown that calcium intake affects the risk of CVD, CHD, or MI (92994,93533,97308,107231). Advise patients not to consume more than the recommended daily intake of 1000-1200 mg per day and to consider total calcium intake from both dietary and supplemental sources (17484). Also, advise patients taking calcium supplements to take calcium along with vitamin D (93533).
POSSIBLY UNSAFE ...when used orally in excessive doses. The National Academy of Medicine sets the daily tolerable upper intake level (UL) for calcium according to age as follows: 19-50 years, 2500 mg; 51 years and older, 2000 mg (17506). Doses over these levels can increase the risk of side effects such as kidney stones, hypercalciuria, hypercalcemia, and milk-alkali syndrome. There has also been concern that calcium intake may be associated with an increased risk of cardiovascular disease (CVD) and coronary heart disease (CHD), including myocardial infarction (MI). Some clinical research suggests that calcium intake, often in amounts over the recommended daily intake level of 1000-1300 mg daily for adults, is associated with an increased risk of CVD, CHD, and MI (16118,17482,91350,107233). However, these studies, particularly meta-analyses, have been criticized for excluding trials in which calcium was administered with vitamin D (94137). Many of these trials also only included postmenopausal females. Other analyses report conflicting results, and have not shown that calcium intake affects the risk of CVD, CHD, or MI (92994,93533,97308,107231). Advise patients to not consume more than the recommended daily intake of 1000-1200 mg per day and to consider total calcium intake from both dietary and supplemental sources (17484). Also, advise patients taking calcium supplements to take calcium along with vitamin D (93533).
CHILDREN: LIKELY SAFE

The Institute of Medicine sets the daily tolerable upper intake level (UL) for calcium according to age as follows: 0-6 months, 1000 mg; 6-12 months, 1500 mg; 1-8 years, 2500 mg; 9-18 years, 3000 mg (17506). Doses over these levels can increase the risk of side effects such as kidney stones, hypercalciuria, hypercalcemia, and milk-alkali syndrome.
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally and appropriately (945,1586,3263,3264,17506).
The World Health Organization (WHO) recommends prescribing oral calcium supplementation 1.5-2 grams daily during pregnancy to those with low dietary calcium intake to prevent pre-eclampsia (97347).
PREGNANCY AND LACTATION: POSSIBLY UNSAFE
when used orally in excessive doses.
The Institute of Medicine sets the same daily tolerable upper intake level (UL) for calcium according to age independent of pregnancy status: 9-18 years, 3000 mg; 19-50 years, 2500 mg (17506). Doses over these amounts might increase the risk of neonatal hypocalcemia-induced seizures possibly caused by transient neonatal hypoparathyroidism in the setting of excessive calcium supplementation during pregnancy, especially during the third trimester. Neonatal hypocalcemia is a risk factor for neonatal seizures (97345).
LIKELY SAFE ...when used orally and appropriately. Choline is safe in adults when taken in doses below the tolerable upper intake level (UL) of 3.5 grams daily (3094) ...when used intravenously and appropriately. Intravenous choline 1-4 grams daily for up to 24 weeks has been used with apparent safety (5173,5174).
POSSIBLY UNSAFE ...when used orally in doses above the tolerable upper intake level (UL) of 3. 5 grams daily. Higher doses can increase the risk of adverse effects (3094).
CHILDREN: LIKELY SAFE
when used orally and appropriately (3094).
Choline is safe in children when taken in doses below the tolerable upper intake level (UL), which is 1 gram daily for children 1-8 years of age, 2 grams daily for children 9-13 years of age, and 3 grams daily for children 14-18 years of age (3094).
CHILDREN: POSSIBLY UNSAFE
when used orally in doses above the UL.
High doses can increase the risk of adverse effects (3094).
PREGNANCY AND LACTATION: LIKELY SAFE

Choline is safe when taken in doses below the tolerable upper intake level (UL), which is 3 grams daily during pregnancy and lactation in those up to 18 years of age and 3.5 grams daily for those 19 years and older (3094,92114). There is insufficient reliable information available about the safety of choline used in higher doses during pregnancy and lactation.
LIKELY SAFE ...when used orally and appropriately in medicinal amounts, short-term. Chromium has been safely used in doses up to 1000 mcg daily for up to 6 months (1934,5039,5040,6858,6859,6860,6861,6862,6867,6868)(7135,7137,10309,13053,14325,14440,17224,90057,90061)(90063,94234,95095,95096,95097,98687); however, most of these studies have used chromium doses in a range of 150-600 mcg. The Food and Drug Administration (FDA) and Institute of Medicine (IOM) evaluations of the safety of chromium suggest that it is safe when used in doses of 200 mcg daily for up to 6 months (13241,13242).
POSSIBLY SAFE ...when used orally and appropriately in medicinal amounts, long-term. Chromium has been safely used in a small number of studies at doses of 200-1000 mcg daily for up to 2 years (7060,7135,42618,42628,42666,110605,110607,110609). However, the Food and Drug Administration (FDA) and Institute of Medicine (IOM) evaluations of the safety of chromium suggest that it is safe when used in doses of 200 mcg daily for up to 6 months (13241,13242).
CHILDREN: LIKELY SAFE

POSSIBLY SAFE...when used orally and appropriately in amounts exceeding AI levels. Chromium 400 mcg daily has been used safely for up to 6 weeks (42680).
PREGNANCY: LIKELY SAFE
when used orally and appropriately in amounts not exceeding adequate intake (AI) levels.
The AI for pregnancy is 28 mcg daily for those 14-18 years of age and 30 mcg daily for those 19-50 years of age (7135).
PREGNANCY: POSSIBLY SAFE
when used orally in amounts exceeding the adequate intake (AI) levels.
There is some evidence that patients with gestational diabetes can safely use chromium in doses of 4-8 mcg/kg (1953); however, patients should not take chromium supplements during pregnancy without medical supervision.
LACTATION: LIKELY SAFE
when used orally and appropriately in amounts not exceeding adequate intake (AI) levels.
The AI for lactation is 44 mcg daily for those 14-18 years of age and 45 mcg daily for those 19-50 years of age (7135). Chromium supplements do not seem to increase normal chromium concentration in human breast milk (1937). There is insufficient reliable information available about the safety of chromium when used in higher amounts while breast-feeding.
There is insufficient reliable information available about the safety of evodia when used orally. In animal studies, evodia has induced QT interval prolongation and Torsade de pointes (97035). It is not clear what dose, if any, is required to produce a similar effect in humans.
PREGNANCY: POSSIBLY UNSAFE
when used orally.
Active constituents in evodia have uterine stimulant activity in animal models. Evodia might also decrease litter size in animal models (15229). Theoretically, taking evodia during pregnancy might adversely affect pregnancy outcome.

LIKELY SAFE ...when used orally and appropriately. For people age 14 and older with adequate iron stores, iron supplements are safe when used in doses below the tolerable upper intake level (UL) of 45 mg per day of elemental iron. The UL is not meant to apply to those who receive iron under medical supervision (7135,96621). To treat iron deficiency, most people can safely take up to 300 mg elemental iron per day (15). ...when used intravenously and appropriately. Ferric carboxymaltose 200 mg and iron sucrose 200 mg have been given intravenously for up to 10 doses with no reported serious adverse effects (91179). A meta-analysis of clinical studies of hemodialysis patients shows that administering high-dose intravenous (IV) iron does not increase the risk of hospitalization, infection, cardiovascular events, or death when compared with low-dose IV iron, oral iron, or no iron treatment (102861). A more recent meta-analysis of clinical studies of all patient populations shows that administering IV iron does not increase the risk of hospital length of stay or mortality, although the risk of infection is increased by 16% when compared with oral iron or no iron (110186). Despite these findings, there are rare reports of hypophosphatemia and/or osteomalacia (112603,112608,112609,112610).
LIKELY UNSAFE ...when used orally in excessive doses. Doses of 30 mg/kg are associated with acute toxicity. Long-term use of high doses of iron can cause hemosiderosis and multiple organ damage. The estimated lethal dose of iron is 180-300 mg/kg; however, doses as low as 60 mg/kg have also been lethal (15).
CHILDREN: LIKELY SAFE

CHILDREN: LIKELY UNSAFE
when used orally in excessive amounts.
Tell patients who are not iron-deficient not to use doses above the tolerable upper intake level (UL) of 40 mg per day of elemental iron for infants and children. Higher doses frequently cause gastrointestinal side effects such as constipation and nausea (7135,20097). Iron is the most common cause of pediatric poisoning deaths. Doses as low as 60 mg/kg can be fatal (15).
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally and appropriately.
Iron is safe during pregnancy and breast-feeding in patients with adequate iron stores when used in doses below the tolerable upper intake level (UL) of 45 mg daily of elemental iron (7135,96625,110180).
PREGNANCY AND LACTATION: LIKELY UNSAFE

Supplemental doses of L-carnitine have been given to infants in breast milk and formula with no reported adverse effects. The effects of large doses used while nursing are unknown, but L-carnitine is secreted in the breast milk (3616).
LIKELY SAFE ...when used orally in food amounts. Raspberry ketone has Generally Recognized as Safe (GRAS) status for use as a food additive (102356,102358). There is insufficient reliable information available about the safety of raspberry ketone when used in medicinal amounts. However, raspberry ketone is structurally similar to synephrine, a known stimulant agent. Orally, cases of heart palpitations, tachycardia, elevated blood pressure, coronary vasospasm, sweating, feelings of shakiness, and diarrhea are reported after taking raspberry ketone (17961,112386,112400). In one case report, pulseless electrical activity arrest followed by resistant polymorphic ventricular tachycardia occurred in a patient taking raspberry ketone (112386).

Higher intake can cause hypertension (26229).
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally and appropriately.
Sodium is safe in amounts that do not exceed the CDRR intake level of 2.3 grams daily (100310).
PREGNANCY AND LACTATION: POSSIBLY UNSAFE
when used orally in higher doses.
Higher intake can cause hypertension (100310). Also, both the highest and the lowest pre-pregnancy sodium quintile intakes are associated with an increased risk of hypertensive disorders of pregnancy, including gestational hypertension and pre-eclampsia, and the delivery of small for gestational age (SGA) infants when compared to the middle intake quintile (106264).
Below is general information about the interactions of the known ingredients contained in the product AdrenHERlyn Cuts. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
1,3-DMAA strongly inhibits cytochrome P450 2D6 (CYP2D6) enzymes in vitro (91878). Theoretically, 1,3-DMAA can increase levels of CYP2D6 substrates. Some of drugs that are CYP2D6 substrates include amitriptyline (Elavil), clozapine (Clozaril), codeine, desipramine (Norpramin), donepezil (Aricept), fentanyl (Duragesic), flecainide (Tambocor), fluoxetine (Prozac), meperidine (Demerol), methadone (Dolophine), metoprolol (Lopressor, Toprol XL), olanzapine (Zyprexa), ondansetron (Zofran), tramadol (Ultram), trazodone (Desyrel), and others.
|
1,3-DMAA is thought to have stimulant effects (94367). There is concern that taking 1,3-DMAA with stimulant drugs might increase the risk of adverse cardiovascular effects. Some preliminary research shows that taking 1,3-DMAA 50 mg daily in combination with caffeine 250 mg daily does not increase respiratory rate, blood pressure, or other cardiovascular outcomes compared to taking caffeine alone in healthy men (94364). However, a number of cardiovascular side effects have been reported for patients taking 1,3-DMAA in combination with other stimulants including caffeine (17660,91680,94362,94365,94371,94377). Theoretically, combining 1,3-DMAA with stimulant drugs might increase the risk of adverse cardiovascular effects. Some stimulant drugs include amphetamine, caffeine, diethylpropion (Tenuate), methylphenidate, phentermine (Ionamin), pseudoephedrine (Sudafed, others), and many others.
|
Theoretically, caffeine might decrease the vasodilatory effects of adenosine and interfere with its use prior to stress testing.
Details
Some evidence shows that caffeine is a competitive inhibitor of adenosine and can reduce the vasodilatory effects of adenosine in humans (38172). However, other research shows that caffeine does not seem to affect supplemental adenosine because high interstitial levels of adenosine overcome the antagonistic effects of caffeine (11771). It is recommended that methylxanthines and methylxanthine-containing products be stopped 24 hours prior to pharmacological stress tests (11770). However, methylxanthines appear more likely to interfere with dipyridamole (Persantine) than adenosine-induced stress testing (11771).
|
Theoretically, concomitant use might increase levels and adverse effects of caffeine.
Details
Alcohol reduces caffeine metabolism. Concomitant use of alcohol can increase caffeine serum concentrations and the risk of caffeine adverse effects (6370).
|
Theoretically, caffeine may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Details
|
Theoretically, taking caffeine with antidiabetes drugs might interfere with blood glucose control.
Details
|
Theoretically, large amounts of caffeine might increase the cardiac inotropic effects of beta-agonists (15).
|
Theoretically, caffeine might reduce the effects of carbamazepine and increase the risk for convulsions.
Details
Animal research suggests that taking caffeine can lower the anticonvulsant effects of carbamazepine and can induce seizures when taken in doses above 400 mg/kg (23559,23561). Human research has shown that taking caffeine 300 mg in three divided doses along with carbamazepine 200 mg reduces the bioavailability of carbamazepine by 32% and prolongs the plasma half-life of carbamazepine 2-fold in healthy individuals (23562).
|
Theoretically, cimetidine might increase the levels and adverse effects of caffeine.
Details
Cimetidine decreases the rate of caffeine clearance by 31% to 42% (11736).
|
Caffeine might increase the levels and adverse effects of clozapine and acutely exacerbate psychotic symptoms.
Details
Caffeine might increase the effects and toxicity of clozapine. Caffeine doses of 400-1000 mg per day inhibit clozapine metabolism (5051). Clozapine is metabolized by cytochrome P450 1A2 (CYP1A2). Although researchers speculate that caffeine might inhibit CYP1A2, there is no reliable evidence that caffeine affects CYP1A2. There is also speculation that genetic factors might make some patients more sensitive to an interaction between clozapine and caffeine (13741). In one case report, severe, life-threatening clozapine toxicity and multiorgan system failure occurred in a patient with schizophrenia stabilized on clozapine who consumed caffeine 600 mg daily (108817).
|
Theoretically, contraceptive drugs might increase the levels and adverse effects of caffeine.
Details
|
Theoretically, concomitant use might increase the levels and adverse effects of caffeine.
Details
|
Theoretically, caffeine might decrease the vasodilatory effects of dipyridamole and interfere with its use prior to stress testing.
Details
Caffeine inhibits dipyridamole-induced vasodilation (11770,11772). It is recommended that methylxanthines and methylxanthine-containing products be stopped 24 hours prior to pharmacological stress tests (11770). Methylxanthines appear more likely to interfere with dipyridamole (Persantine) than adenosine-induced stress testing (11771).

Details
Methoxsalen reduces caffeine metabolism (23572).
|
Theoretically, mexiletine might increase the levels and adverse effects of caffeine.
Details

Theoretically, concomitant use might increase the risk of a hypertensive crisis.
Details
Caffeine has been shown to inhibit monoamine oxidase (MAO) A and B in laboratory studies (37724,37877,37912,38108). Concomitant intake of large amounts of caffeine with MAOIs might precipitate a hypertensive crisis (15). In a case report, a patient that consumed 10-12 cups of caffeinated coffee and took the MAOI tranylcypromine presented with severe hypertension (91086). Hypertension was resolved after the patient switched to drinking decaffeinated coffee.
|
Theoretically, concomitant use might increase the risk of hypertension.
Details
Concomitant use of caffeine and nicotine has been shown to have additive cardiovascular effects, including increased heart rate and blood pressure. Blood pressure was increased by 10.8/12.4 mmHg when the agents were used concomitantly (36549).
|

Details
|
Theoretically, caffeine might reduce the effects of phenytoin and increase the risk for convulsions.
Details
|
Theoretically, caffeine might increase the levels and clinical effects of pioglitazone.
Details
Animal research suggests that caffeine can modestly increase the maximum concentration, area under the curve, and half-life of pioglitazone, and also reduce its clearance. This increased the antidiabetic effects of pioglitazone (108812). However, the exact mechanism of this interaction is unclear.
|
Theoretically, quinolone antibiotics might increase the levels and adverse effects of caffeine.
Details
|
Theoretically, concomitant use might increase the levels and adverse effects of both caffeine and riluzole.
Details
Caffeine and riluzole are both metabolized by cytochrome P450 1A2 (CYP1A2), and concomitant use might reduce the metabolism of one or both agents (11739).
|
Theoretically, concomitant use might increase stimulant adverse effects.
Details
Due to the central nervous system (CNS) stimulant effects of caffeine, concomitant use with stimulant drugs can increase the risk of adverse effects (11832).
|
Theoretically, terbinafine might increase the levels and adverse effects of caffeine.
Details
Terbinafine decreases the clearance of intravenous caffeine by 19% (11740).
|
Theoretically, caffeine might increase the levels and adverse effects of theophylline.
Details
Large amounts of caffeine might inhibit theophylline metabolism (11741).
|
Theoretically, caffeine might increase the levels and adverse effects of tiagabine.
Details
Animal research suggests that chronic caffeine administration can increase the serum concentrations of tiagabine. However, concomitant use does not seem to reduce the antiepileptic effects of tiagabine (23561).
|
Theoretically, ticlopidine might increase the levels and adverse effects of caffeine.
Details
In vitro evidence suggests that ticlopidine can inhibit caffeine metabolism (23557). However, this effect has not been reported in humans.
|
Theoretically, caffeine might reduce the effects of valproate and increase the risk for convulsions.
Details
|
Theoretically, verapamil might increase the levels and adverse effects of caffeine.
Details
Verapamil increases plasma caffeine concentrations by 25% (11741).
|
Calcium citrate might increase aluminum absorption and toxicity. Other types of calcium do not increase aluminum absorption.
Details
Calcium citrate can increase the absorption of aluminum when taken with aluminum hydroxide. The increase in aluminum levels may become toxic, particularly in individuals with kidney disease (21631). However, the effect of calcium citrate on aluminum absorption is due to the citrate anion rather than calcium cation. Calcium acetate does not appear to increase aluminum absorption (93006).
|
Calcium reduces the absorption of bisphosphonates.
Details
Advise patients to take bisphosphonates at least 30 minutes before calcium, but preferably at a different time of day. Calcium supplements decrease absorption of bisphosphonates (12937).
|
Taking calcipotriene with calcium might increase the risk for hypercalcemia.
Details
Calcipotriene is a vitamin D analog used topically for psoriasis. It can be absorbed in sufficient amounts to cause systemic effects, including hypercalcemia (12938). Theoretically, combining calcipotriene with calcium supplements might increase the risk of hypercalcemia.
|
Intravenous calcium may decrease the effects of calcium channel blockers; oral calcium is unlikely to have this effect.
Details
Intravenous calcium is used to decrease the effects of calcium channel blockers in the management of overdose. Intravenous calcium gluconate has been used before intravenous verapamil (Isoptin) to prevent or reduce the hypotensive effects without affecting the antiarrhythmic effects (6124). But there is no evidence that dietary or supplemental calcium when taken orally interacts with calcium channel blockers (12939,12947).
|
Co-administration of intravenous calcium and ceftriaxone can result in precipitation of a ceftriaxone-calcium salt in the lungs and kidneys.
Details
Avoid administering intravenous calcium in any form, such as parenteral nutrition or Lactated Ringers, within 48 hours of intravenous ceftriaxone. Case reports in neonates show that administering intravenous ceftriaxone and calcium can result in precipitation of a ceftriaxone-calcium salt in the lungs and kidneys. In several cases, neonates have died as a result of this interaction (15794,21632). So far there are no reports in adults; however, there is still concern that this interaction might occur in adults.
|
Using intravenous calcium with digoxin might increase the risk of fatal cardiac arrhythmias.
Details
|
Theoretically, calcium may reduce the therapeutic effects of diltiazem.
Details
Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation (10574). Theoretically, calcium might increase this risk of hypercalcemia and reduce the effectiveness of diltiazem.
|
Calcium seems to reduce levels of dolutegravir.
Details
Advise patients to take dolutegravir either 2 hours before or 6 hours after taking calcium supplements. Pharmacokinetic research suggests that taking calcium carbonate 1200 mg concomitantly with dolutegravir 50 mg reduces plasma levels of dolutegravir by almost 40%. Calcium appears to decrease levels of dolutegravir through chelation (93578).
|
Calcium seems to reduce levels of elvitegravir.
Details
Advise patients to take elvitegravir either 2 hours before or 2 hours after taking calcium supplements. Pharmacokinetic research suggests that taking calcium along with elvitegravir can reduce blood levels of elvitegravir through chelation (94166).
|
Calcium seems to reduce the absorption and effectiveness of levothyroxine.
Details
|
Theoretically, concomitant use of calcium and lithium may increase this risk of hypercalcemia.
Details
Clinical research suggests that long-term use of lithium may cause hypercalcemia in 10% to 60% of patients (38953). Theoretically, concomitant use of lithium and calcium supplements may further increase this risk.
|
Calcium seems to reduce the absorption of quinolone antibiotics.
Details
|
Calcium may reduce levels of raltegravir.
Details
Pharmacokinetic research shows that taking a single dose of calcium carbonate 3000 mg along with raltegravir 400 mg twice daily modestly decreases the mean area under the curve of raltegravir, but the decrease does not necessitate a dose adjustment of raltegravir (94164). However, a case of elevated HIV-1 RNA levels and documented resistance to raltegravir has been reported for a patient taking calcium carbonate 1 gram three times daily plus vitamin D3 (cholecalciferol) 400 IU three times daily in combination with raltegravir 400 mg twice daily for 11 months. It is thought that calcium reduced raltegravir levels by chelation, leading to treatment failure (94165).
|
Calcium seems to reduce the absorption of sotalol.
Details
Advise patients to separate doses by at least 2 hours before or 4-6 hours after calcium. Calcium appears to reduce the absorption of sotalol, probably by forming insoluble complexes (10018).
|
Calcium seems to reduce the absorption of tetracycline antibiotics.
Details
Advise patients to take oral tetracyclines at least 2 hours before, or 4-6 hours after calcium supplements. Taking calcium at the same time as oral tetracyclines can reduce tetracycline absorption. Calcium binds to tetracyclines in the gut (1843).
|
Taking calcium along with thiazides might increase the risk of hypercalcemia and renal failure.
Details
Thiazides reduce calcium excretion by the kidneys (1902). Using thiazides along with moderately large amounts of calcium carbonate increases the risk of milk-alkali syndrome (hypercalcemia, metabolic alkalosis, renal failure). Patients may need to have their serum calcium levels and/or parathyroid function monitored regularly.
|
Theoretically, calcium may reduce the therapeutic effects of verapamil.
Details
Hypercalcemia can reduce the effectiveness of verapamil in atrial fibrillation (10574). Theoretically, use of calcium supplements may increase this risk of hypercalcemia and reduce the effectiveness of verapamil.
|
Theoretically, choline might decrease the effects of atropine in the brain.
Details
Animal research shows that administering choline one hour before administering atropine can attenuate atropine-induced decreases in brain levels of acetylcholine (42240). Theoretically, concomitant use of choline and atropine may decrease the effects of atropine.
|
Theoretically, chromium may have additive effects with antidiabetic agents and increase the risk of hypoglycemia.
Details
|
Theoretically, aspirin might increase chromium absorption.
Details
Animal research suggests that aspirin may increase chromium absorption and chromium levels in the blood (21055).
|
Theoretically, concomitant use of chromium and insulin might increase the risk of hypoglycemia.
Details
|
Chromium might bind levothyroxine in the intestinal tract and decrease levothyroxine absorption.
Details
Clinical research in healthy volunteers shows that taking chromium picolinate 1000 mcg with levothyroxine 1 mg decreases serum levels of levothyroxine by 17% when compared to taking levothyroxine alone (16012). Advise patients to take levothyroxine at least 30 minutes before or 3-4 hours after taking chromium.
|
NSAIDs might increase chromium levels in the body.
Details
Drugs that are prostaglandin inhibitors, such as NSAIDs, seem to increase chromium absorption and retention (7135).
|
Theoretically, taking evodia with antiplatelet or anticoagulant drugs might increase the risk of bruising and bleeding.
Details
|
Theoretically, evodia might decrease the levels and clinical effects of caffeine.
Details
In animal models, evodia extract decreases caffeine levels by up to 71%. Evodia extract induces hepatic cytochrome P450 1A2 (CYP1A2) enzyme, of which caffeine is a substrate (15241).
|
Theoretically, evodia might decrease the levels and clinical effects of chlorzoxazone.
Details
Animal research shows that administration of rutaecarpine, a constituent of evodia, with chlorzoxazone reduces the area under the curve (AUC) of chlorzoxazone by 84% and increases its clearance by 646%. This interaction is likely due to induction of cytochrome P450 2E1 (CYP2E1) by rutaecarpine (107913).
|
Theoretically, drugs that inhibit CYP1A2 might increase the levels and clinical effects of evodia.
Details
The evodia constituent rutaecarpine is metabolized by CYP1A2 (15253).
|
Evodia might reduce the levels and clinical effects of CYP1A2 substrates through induction of CYP1A2.
Details
|
Theoretically, evodia might reduce the levels and clinical effects of CYP2E1 substrates through induction of CYP2E1.
Details
Animal research suggests that rutaecarpine, a constituent of evodia, induces CYP2E1 activity. In rats, rutaecarpine increases markers of CYP2E1 activity, and administration of rutaecarpine with chlorzoxazone, a known CYP2E1 substrate, reduces the area under the curve (AUC) of chlorzoxazone by 84% and increases its clearance by 646% (107913).
|
Theoretically, taking CYP3A4 inducers might decrease the levels and clinical effects of evodia.
Details
Animal research shows that concomitant administration of dexamethasone, a known CYP3A4 inducer, with the alkaloid constituents of evodia significantly reduces the area under the curve (AUC), maximum concentration (Cmax), and half-life of these constituents (107911).
|
Theoretically, CYP3A4 inhibitors might increase the levels and clinical effects of evodia.
Details
Animal research shows that concomitant administration of ketoconazole, a known CYP3A4 inhibitor, with the alkaloid constituents of evodia significantly increases the area under the curve (AUC), maximum concentration (Cmax), and half-life of these constituents (107911).
|
Theoretically, evodia might increase the levels and clinical effects of CYP3A4 substrates.
Details
In vitro research shows that evodia extract inhibits hepatic CYP3A4 (15236). This effect has not been reported in humans.
|
Theoretically, evodia might have an additive effect with drugs that prolong the QT interval, potentially increasing the risk of ventricular arrhythmias.
Details
Evodia has demonstrated dose-dependent activity as a proarrhythmic agent in animal and in vitro studies. Evodia infusion in animals extends the action duration potential and induces prolongation of the QT interval and Torsade de pointes (97035).
|
Theoretically, evodia might decrease the levels and clinical effects of theophylline.
Details
The evodia constituent rutaecarpine decreases theophylline levels and half-life by about 70% in animal models (15227). This constituent appears to induce hepatic cytochrome P450 1A2 (CYP1A2) enzyme activity, of which theophylline is a substrate (15227,15230). Rutaecarpine is the primary active constituent of evodia; however, it is not known if the whole crude extract of evodia also causes this interaction.
|
Iron reduces the absorption of bisphosphonates.
Details
Advise patients that doses of bisphosphonates should be separated by at least two hours from doses of all other medications, including supplements such as iron. Divalent cations, including iron, can decrease absorption of bisphosphonates by forming insoluble complexes in the gastrointestinal tract (15).
|
Theoretically, taking chloramphenicol with iron might reduce the response to iron therapy in iron deficiency anemia.
Details
|
Iron might decrease dolutegravir levels by reducing its absorption.
Details
Advise patients to take dolutegravir at least 2 hours before or 6 hours after taking iron. Pharmacokinetic research shows that iron can decrease the absorption of dolutegravir from the gastrointestinal tract through chelation (93578). When taken under fasting conditions, a single dose of ferrous fumarate 324 mg orally along with dolutegravir 50 mg reduces overall exposure to dolutegravir by 54% (94190).
|
Theoretically, taking iron along with integrase inhibitors might decrease the levels and clinical effects of these drugs.
Details
Iron is a divalent cation. There is concern that iron may decrease the absorption of integrase inhibitors from the gastrointestinal tract through chelation (93578). One pharmacokinetic study shows that iron can decrease blood levels of the specific integrase inhibitor dolutegravir through chelation (94190). Also, other pharmacokinetic research shows that other divalent cations such as calcium can decrease the absorption and levels of some integrase inhibitors through chelation (93578,93579).
|
Iron might decrease levodopa levels by reducing its absorption.
Details
Advise patients to separate doses of levodopa and iron as much as possible. There is some evidence in healthy people that iron forms chelates with levodopa, reducing the amount of levodopa absorbed by around 50% (9567). The clinical significance of this hasn't been determined.
|
Iron might decrease levothyroxine levels by reducing its absorption.
Details
Advise patients to separate levothyroxine and iron doses by at least 2 hours. Iron can decrease the absorption and efficacy of levothyroxine by forming insoluble complexes in the gastrointestinal tract (9568).
|
Iron might decrease methyldopa levels by reducing its absorption.
Details
|
Theoretically, iron might decrease mycophenolate mofetil levels by reducing its absorption.
Details
Advise patients to take iron 4-6 hours before, or 2 hours after, mycophenolate mofetil. It has been suggested that a decrease of absorption is possible, probably by forming nonabsorbable chelates. However, mycophenolate pharmacokinetics are not affected by iron supplementation in available clinical research (3046,20152,20153,20154,20155).
|
Iron might decrease penicillamine levels by reducing its absorption.
Details
Advise patients to separate penicillamine and iron doses by at least 2 hours. Oral iron supplements can reduce absorption of penicillamine by 30% to 70%, probably due to chelate formation. In people with Wilson's disease, this interaction has led to reduced efficacy of penicillamine (3046,3072,20156).
|
Iron might decrease levels of quinolone antibiotics by reducing their absorption.
Details
|
Iron might decrease levels of tetracycline antibiotics by reducing their absorption.
Details
Advise patients to take iron at least 2 hours before or 4 hours after tetracycline antibiotics. Concomitant use can decrease absorption of tetracycline antibiotics from the gastrointestinal tract by 50% to 90% (15).
|
Theoretically, L-carnitine might increase the anticoagulant effects of acenocoumarol.
Details
L-carnitine might enhance the anticoagulant effects of acenocoumarol, an oral anticoagulant similar to warfarin, but shorter-acting (9878,12165). There are at least two case reports of INR elevation with concomitant use. In one case, a 33-year-old male with a previously stable INR had an elevated INR of 4.65 after L-carnitine was started and continued for 10 weeks. INR normalized after discontinuation of the L-carnitine-containing product (12165).
|
Theoretically, L-carnitine might decrease the effectiveness of thyroid hormone replacement.
Details
|
Theoretically, L-carnitine might increase the anticoagulant effects of warfarin.
Details
|
Theoretically, raspberry ketone might increase the risk of adverse cardiovascular effects with stimulant drugs.
Details
Structurally, raspberry ketone resembles synephrine, a known stimulant agent. Heart palpitations, elevated blood pressure, coronary vasospasm, pulseless electrical activity arrest, and resistant polymorphic ventricular tachycardia have been reported in patients taking raspberry ketone (17961,112386,112400).
|
Theoretically, raspberry ketone might increase warfarin dose requirements.
Details
In one case report, a patient taking warfarin 55 mg per week had a decrease in INR over a period of one month while taking raspberry ketone 250 mg daily. A warfarin dose increase to 70 mg per week was necessary to maintain a therapeutic INR while taking raspberry ketone (17962). The mechanism for this potential interaction is not known.
|
Theoretically, a high intake of dietary sodium might reduce the effectiveness of antihypertensive drugs.
Details
|
Concomitant use of mineralocorticoids and some glucocorticoids with sodium supplements might increase the risk of hypernatremia.
Details
Mineralocorticoids and some glucocorticoids (corticosteroids) cause sodium retention. This effect is dose-related and depends on mineralocorticoid potency. It is most common with hydrocortisone, cortisone, and fludrocortisone, followed by prednisone and prednisolone (4425).
|
Altering dietary intake of sodium might alter the levels and clinical effects of lithium.
Details
High sodium intake can reduce plasma concentrations of lithium by increasing lithium excretion (26225). Reducing sodium intake can significantly increase plasma concentrations of lithium and cause lithium toxicity in patients being treated with lithium carbonate (26224,26225). Stabilizing sodium intake is shown to reduce the percentage of patients with lithium level fluctuations above 0.8 mEq/L (112909). Patients taking lithium should avoid significant alterations in their dietary intake of sodium.
|
Concomitant use of sodium-containing drugs with additional sodium from dietary or supplemental sources may increase the risk of hypernatremia and long-term sodium-related complications.
Details
The Chronic Disease Risk Reduction (CDRR) intake level of 2.3 grams of sodium daily indicates the intake at which it is believed that chronic disease risk increases for the apparently healthy population (100310). Some medications contain high quantities of sodium. When used in conjunction with sodium supplements or high-sodium diets, the CDRR may be exceeded. Additionally, concomitant use may increase the risk for hypernatremia; this risk is highest in the elderly and people with other risk factors for electrolyte disturbances.
|
Theoretically, concomitant use of tolvaptan with sodium might increase the risk of hypernatremia.
Details
Tolvaptan is a vasopressin receptor 2 antagonist that is used to increase sodium levels in patients with hyponatremia (29406). Patients taking tolvaptan should use caution with the use of sodium salts such as sodium chloride.

Below is general information about the adverse effects of the known ingredients contained in the product AdrenHERlyn Cuts. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
General
...Orally, taking 1,3-DMAA combination products (OxyELITE Pro, AmphetaLean, or Jack3d, USPlabs) has been reported to cause cardiac arrest, atrial fibrillation, chest pressure, angina, tachycardia, palpitations, hypertension, hypotension, myocardial infarction, and acute coronary syndrome (17660,91680,94361,94362,94365,94369,94371,94377).
Increased heart rate and blood pressure have also been reported. Other reported adverse effects associated with the use of 1,3-DMAA-containing products have included life-threatening lactic acidosis (17660), nausea, vomiting, diarrhea, and abdominal pain (17663,17907,17908,94365,94371,94377), urinary changes (17663,94365,94371,94377), liver injury (94367,94368,94369), anaphylaxis (94365), muscle symptoms such as spasm or weakness (94377), neurological symptoms including tremors, insomnia, sweating, tiredness, confusion, headache, and chills (17907,17663), hemorrhagic stroke (17663,90318), pupil dilation or tinnitus (94365,94371), psychiatric symptoms such as anxiety, agitation, paranoia, and aggression (17660,17907,94365,94371,94377), or rapid breathing (17660,94371). The dose of 1,3-DMAA at which such adverse effects occur is not clear (94368).
Death has occurred in some cases following organ failure and cardiac arrest (17904,94361,94369,94374).
Topically, rubbing an eye while mixing a drink with a 1,3-DMAA-containing combination product (Jack3d) has caused pupil dilation (94368).

...Due to the stimulant effects of 1,3-DMAA, there is concern that it might increase the risk of adverse cardiovascular events similar to synephrine from bitter orange or ephedrine from ephedra.
Cardiovascular outcomes have rarely been assessed in patients taking 1,3-DMAA alone. Most adverse effects are linked to 1,3-DMAA-containing combination products. Palpitations and tachycardia are some of the most common side effects reported for adults and children taking 1,3-DMAA-containing combination products (17660,91680,94365,94371). Other less common adverse effects have included chest pressure, angina, atrial fibrillation, hypertension, hypotension, myocardial infarction, and acute coronary syndrome (17660,91680,94362,94365,94371,94377).
There is inconsistent data about the effects of 1,3-DMAA on heart rate and blood pressure (94368). For example, some research suggests that taking specific 1,3-DMAA-containing combination products (OxyELITE Pro or Jack3d, USPlabs) significantly increases systolic blood pressure and increases heart rate within 1-2 hours of taking a dose. These increases appear to be dose dependent (17906,17907,17908). However, in an 8-week study, heart rate was significantly increased, but blood pressure was not (17907). Other research shows that neither acute nor chronic intake of 1,3-DMAA increases heart rate or blood pressure (17908,94364,94368,94376). Overall, it seems that oral intake of a single dose of a 1,3-DMAA-containing product is more likely to increase systolic blood pressure. Resting blood pressure is less likely to remain increased following chronic use (94368,94379). Higher doses are more likely to increase heart rate and blood pressure. Although most sports supplements contain 25-65 mg/dose, some contain as much as 285 mg/dose (94377).
In case reports of healthy young adults taking 1,3-DMAA-containing combination products prior to exercise, cardiac arrest causing death has occurred (94361,94369).
Endocrine ...In one report, a patient who took a specific combination product containing 1,3-DMAA (Jack3d by USP Labs) prior to intense exercise experienced life-threatening lactic acidosis (17660).
Gastrointestinal ...Orally, taking 1,3-DMAA-containing combination products has been reported to cause nausea (17907,17908,94365,94371,94377), vomiting (17663,94365,94371,94377), diarrhea (94365), vomiting blood (94371), and abdominal pain (94371).
Genitourinary ...Urinary hesitancy (94365), urinary retention (94371), and uncontrolled urination (94377), have been reported following ingestion of 1,3-DMAA-containing combination products.
Hepatic ...Acute liver injury, in some cases requiring a liver transplant, has been reported following oral intake of 1,3-DMAA-containing products (94367,94368,94369).
Immunologic ...An anaphylactic reaction has been reported following oral intake of 1,3-DMAA-containing products (94365).
Musculoskeletal ...Orally, dimethylamine-containing products have caused muscle spasm (94365), muscle weakness (94377), and leg pains (94377).
Neurologic/CNS ...Orally, taking specific 1,3-DMAA-containing combination products (OxyELITE Pro or Jack3d, USPlabs) has been reported to cause feelings of jitters, sleeplessness, shakiness, chills, sweating, fatigue, tingling, and lack of focus in clinical trials (17907). Other adverse effects reported for products containing 1,3-DMAA have included headache, dizziness, tremor, numbness, flushing, seizure, blacking out, visual disturbances, confusion, and lethargy (17660,17908,94365,94368,94371,94377). In a case report, a 26 year old male reported with a hemorrhagic stroke linked to taking the supplement Jack3d, which contains 1,3-DMAA, schizandrol A, caffeine, beta-alanine, creatine, and L-arginine alpha-ketoglutarate (90318). In another report, a patient experienced a hemorrhagic stroke after taking two tablets of a product containing 1,3-DMAA 278 mg each along with caffeine 150 mg and a can of beer (17663).
Ocular/Otic ...Orally, dimethylamine-containing products have caused tinnitus (94365) and pupil dilation (94371). Pupil dilation also occurred after rubbing an eye while mixing a drink with the specific product Jack3d, containing 1,3-DMAA (94368).
Psychiatric ...Orally, taking 1,3-DMAA-containing combination products has been reported to cause feelings of anxiety (17907,94365), suicidal behavior (94365), agitation or irritability (94365,94371,94377), paranoia (94377), depression (94377), panic (94377), and aggression or combativeness (17660,94365).
Pulmonary/Respiratory ...Orally, combination products containing 1,3-DMAA have caused rapid breathing and hyperventilation (17660,94371).
Other ...There are at least two reports of death in US Army soldiers who took 1,3-DMAA supplements and suffered heat stroke and related complications following physical fitness training (17904).
General ...Orally, topically, and intravenously, alpha-ketoglutarate seems to be well tolerated.
General
...Orally, beta-alanine seems to be generally well tolerated.
Most Common Adverse Effects:
Orally: Flushing, paresthesia.
Gastrointestinal ...While rare, digestion problems have been reported with oral beta-alanine use (94341).
Neurologic/CNS ...Orally, beta-alanine can cause a dose-dependent feeling of pins and needles (paresthesias) along with skin flushing (16438,94333,94335,94338,94341,94342,94349,101028,101029,106711). This generally starts on the scalp within 20 minutes of the dose, spreading to most of the body, and lasting for about an hour. This was described as severe at a dose of 40 mg/kg, tolerable at a dose of 20 mg/kg, and very mild at a dose of 10 mg/kg. At the lowest dose it only occurred in 25% of subjects (16438). In some studies, beta-alanine has been given as frequently as 8 times per day so that each dose can be kept below 10 mg/kg (16438,16439). Other clinical research shows that taking beta-alanine in a tablet formulation eliminates the presence of parasthesias at a dose of 1.6 grams when compared with a solution made from powdered beta-alanine. This effect may be due to delayed absorption (97974,97975). Although paresthesias still occur with sustained-release formulations, their presence is less frequent when compared with immediate-release formulations (101029).
General
...Caffeine in moderate doses is typically well tolerated.
Most Common Adverse Effects:
Orally: Anxiety, dependence with chronic use, diarrhea, diuresis, gastric irritation, headache, insomnia, muscular tremors, nausea, and restlessness.
Serious Adverse Effects (Rare):
Orally: Stroke has been reported rarely.
Cardiovascular
...Caffeine can temporarily increase blood pressure.
Usually, blood pressure increases 30 minutes after ingestion, peaks in 1-2 hours, and remains elevated for over 4 hours (36539,37732,37989,38000,38300).
Although acute administration of caffeine can cause increased blood pressure, regular consumption does not seem to increase either blood pressure or pulse, even in mildly hypertensive patients (1451,1452,2722,38335). However, the form of caffeine may play a role in blood pressure increase after a more sustained caffeine use. In a pooled analysis of clinical trials, coffee intake was not associated with an increase in blood pressure, while ingesting caffeine 410 mg daily for at least 7 days modestly increased blood pressure by an average of 4.16/2.41 mmHg (37657). Another meta-analysis of clinical research shows that taking caffeine increases systolic and diastolic blood pressure by approximately 2 mmHg when compared with control. Preliminary subgroup analyses suggest that caffeine may increase blood pressure more in males or at doses over 400 mg (112738).
When used prior to intensive exercise, caffeine can increase systolic blood pressure by 7-8 mmHg (38308). The blood pressure-raising effects of caffeine are greater during stress (36479,38334) and after caffeine-abstinence of at least 24 hours (38241).
Epidemiological research suggests there is no association of caffeine consumption with incidence of hypertension (38190). Habitual coffee consumption also doesn't seem to be related to hypertension, but habitual consumption of sugared or diet cola is associated with development of hypertension (13739).
Epidemiological research has found that regular caffeine intake of up to 400 mg daily is not associated with increased incidence of atrial fibrillation (38018,38076,91028,91034,97451,97453,103708), atherosclerosis (38033), cardiac ectopy (91127), stroke (37804), ventricular arrhythmia (95948,97453), and cardiovascular disease in general (37805,98806). One clinical trial shows that in adults with diagnosed heart failure, consumption of 500 mg of coffee does not result in an increased risk for arrhythmia during exercise (95950). However, caffeine intake may pose a greater cardiovascular risk to subjects that are not regular users of caffeine. For example, in one population study, caffeinated coffee consumption was associated with an increased risk of ischemic stroke in subjects that don't regularly drink coffee (38102). In a population study in Japanese subjects, caffeine-containing medication use was modestly associated with hemorrhagic stroke in adults that do not consume caffeine regularly (91059).
The most common side effect of caffeine in neonates receiving caffeine for apnea is tachycardia (98807).
Dermatologic ...There are several case reports of urticaria after caffeine ingestion (36546,36448,36475).
Endocrine
...Some evidence shows caffeine is associated with fibrocystic breast disease or breast cancer in females; however, this is controversial since findings are conflicting (8043,108806).
Restricting caffeine in females with fibrocystic breast conditions doesn't seem to affect breast nodularity, swelling, or pain (8996). A population analysis of the Women's Health Initiative observational study has found no association between consumption of caffeine-containing beverages and the incidence of invasive breast cancer in models adjusted for demographic, lifestyle, and reproductive factors (108806). Also, a dose-response analysis of 2 low-quality observational studies has found that high consumption of caffeine is not associated with an increased risk of breast cancer (108807).
Clinical research in healthy adults shows that an increase consumption of caffeine results in increased insulin resistance (91023).
Gastrointestinal ...Gastrointestinal upset, nausea, diarrhea, abdominal pain, and fecal incontinence may occur with caffeine intake (36466,37755,37806,37789,37830,38138,38136,38223,95956,95963). Also, caffeine may cause feeding intolerance and gastrointestinal irritation in infants (6023). Perioperative caffeine during cardiopulmonary bypass surgery seems to increase the rate of postoperative nausea and vomiting (97451). Caffeine and coffee consumption have been associated with an increase in the incidence of heartburn (37545,37575,38251,38259,38267) and gastrointestinal esophageal reflux disease (GERD) (38329,37633,37631,37603).
Genitourinary ...Caffeine, a known diuretic, may increase voiding, give a sense of urgency, and irritate the bladder (37874,37961,104580). In men with lower urinary tract symptoms, caffeine intake increased the risk of interstitial cystitis/painful bladder syndrome (38115). Excessive caffeine consumption may worsen premenstrual syndrome. Consumption of up to 10 cups of caffeinated drinks daily was associated with increased severity of premenstrual syndrome (38177). Finally, population research shows that exposure to caffeine was not associated with an increased risk of endometriosis (91035).
Immunologic ...Caffeine can cause anaphylaxis in sensitive individuals, although true IgE-mediated caffeine allergy seems to be relatively rare (11315).
Musculoskeletal
...Caffeine can induce or exacerbate muscular tremors (38136,37673,38161).
There has also been a report of severe rhabdomyolysis in a healthy 40-year-old patient who consumed an energy drink containing 400 mg of caffeine (4 mg/kg) and then participated in strenuous weightlifting exercise (108818).
Epidemiological evidence regarding the relationship between caffeine use and the risk for osteoporosis is contradictory. Caffeine can release calcium from storage sites and increase its urinary excretion (2669,10202,11317,111489). Females with a genetic variant of the vitamin D receptor appear to be at an increased risk for the detrimental effect of caffeine on bone mass (2669). However, moderate caffeine intake, less than 300 mg daily, does not seem to significantly increase osteoporosis risk in most postmenopausal adults with normal calcium intake (2669,6025,10202,11317). Premature infants treated with intravenous caffeine for apnea of prematurity, have a lower bone mineral content compared with infants who are not treated with caffeine, especially when treatment extends beyond 14 days (111489).
Neurologic/CNS ...Caffeine can cause headaches, anxiety, jitteriness, restlessness, and nervousness (36466,37694,37755,37806,37865,37830,37889,38223,95952). In adolescents, there is an inverse correlation between the consumption of caffeine and various measurements of cognitive function (104579). Insomnia is a frequent adverse effect in children (10755). Caffeine may result in insomnia and sleep disturbances in adults as well (36445,36483,36512,36531,37598,37795,37819,37862,37864,37890)(37968,37971,38091,38242,91022,92952). Additionally, caffeine may exacerbate sleep disturbances in patients with acquired immunodeficiency syndrome (AIDS) (10204). Combining ephedra with caffeine can increase the risk of adverse effects. Jitteriness, hypertension, seizures, temporary loss of consciousness, and hospitalization requiring life support has been associated with the combined use of ephedra and caffeine (2729). Finally, epidemiological research suggests that consuming more than 190 mg of caffeine daily is associated with an earlier onset of Huntington disease by 3.6 years (91078).
Ocular/Otic
...In individuals with glaucoma, coffee consumption and caffeine intake has been found to increase intraocular pressure (8540,36464,36465,37670).
The magnitude of this effect seems to depend on individual tolerance to caffeine. Some research in healthy young adults shows that caffeine increases intraocular pressure to a greater degree in low-consumers of caffeine (i.e., 1 cup of coffee or less daily) when compared to high-consumers (i.e., those consuming 2 cups of coffee or more daily) (100371). The peak increase of intraocular pressure seems to occur at about 1.5 hours after caffeine ingestion, and there is no notable effect 4 hours after ingestion (36462,100371).
Oncologic ...Most human studies which have examined caffeine or methylxanthine intake have found that they do not play a role in the development of various cancers, including breast, ovarian, brain, colon, rectal, or bladder cancer (37641,37737,37775,37900,38050,38169,38220,91054,91076,108806).
Psychiatric
...Caffeine may lead to habituation and physical dependence (36355,36453,36512,36599), with amounts as low as 100 mg daily (36355,36453).
An estimated 9% to 30% of caffeine consumers could be considered addicted to caffeine (36355). Higher doses of caffeine have caused nervousness, agitation, anxiety, irritability, delirium, depression, sleep disturbances, impaired attention, manic behavior, psychosis and panic attacks (36505,37717,37818,37839,37857,37982,38004,38017,38028,38072)(38079,38138,38306,38325,38331,38332,97464). Similar symptoms have been reported in a caffeine-naïve individual experiencing fatigue and dehydration after a dose of only 200 mg, with resolution of symptoms occurring within 2 hours (95952).
Withdrawal: The existence or clinical importance of caffeine withdrawal is controversial. Some researchers think that if it exists, it appears to be of little clinical significance (11839). Headache is the most common symptom, due to cerebral vasodilation and increased blood flow (37769,37991,37998). Other researchers suggest symptoms such as tiredness and fatigue, decreased energy, alertness and attentiveness, drowsiness, decreased contentedness, depressed mood, difficulty concentration, irritability, and lack of clear-headedness are typical of caffeine withdrawal (13738). Withdrawal symptoms typically occur 12-24 hours after the last dose of caffeine and peak around 48 hours (37769,36600). Symptoms may persist for 2-9 days. Withdrawal symptoms such as delirium, nausea, vomiting, rhinorrhea, nervousness, restlessness, anxiety, muscle tension, muscle pains, and flushed face have been described. However, these symptoms may be from nonpharmacological factors related to knowledge and expectation of effects. Clinically significant symptoms caused by caffeine withdrawal may be uncommon (2723,11839). In a case report, caffeine consumption of 560 mg daily was associated with increased suicidality (91082).
Renal ...Data on the relationship between caffeine intake and kidney stones are conflicting. Some clinical research shows that caffeine consumption may increase the risk of stone formation (37634,111498), while other research shows a reduced risk with increasing caffeine intakes (111498). A meta-analysis of 7 studies found that overall, there is an inverse relationship, with a 32% decrease in the risk of kidney stones between the lowest and highest daily intakes of caffeine (111498).
Other ...People with voice disorders, singers, and other voice professionals are often advised against the use of caffeine; however, this recommendation has been based on anecdotal evidence. One small exploratory study suggests that caffeine ingestion may adversely affect subjective voice quality, although there appears to be significant intra-individual variability. Further study is necessary to confirm these preliminary findings (2724).
General
...Orally and intravenously, calcium is well-tolerated when used appropriately.
Most Common Adverse Effects:
Orally: Belching, constipation, diarrhea, flatulence, and stomach upset.
Serious Adverse Effects (Rare):
Orally: Case reports have raised concerns about calciphylaxis and kidney stones.
Cardiovascular
...There has been concern that calcium intake may be associated with an increased risk of cardiovascular disease (CVD) and coronary heart disease (CHD), including myocardial infarction (MI).
Some clinical research suggests that calcium intake, often in amounts over the recommended daily intake level of 1000-1300 mg daily for adults, is associated with an increased risk of CVD, CHD, and MI (16118,17482,91350,107233). However, these results, particularly meta-analyses, have been criticized for excluding trials in which calcium was administered with vitamin D (94137). Many of these trials also only included postmenopausal females. Other analyses report conflicting results, and have not shown that calcium intake affects the risk of CVD, CHD, or MI (92994,93533,97308,107231). Reasons for these discrepancies are not entirely clear. It may relate to whether calcium is taken as monotherapy or in combination with vitamin D. When taken with vitamin D, which is commonly recommended, calcium supplementation does not appear to be associated with an increased risk of CVD, CHD, or MI (93533,107231). Also, the association between calcium supplementation and CVD, CHD, or MI risk may be influenced by the amount of calcium consumed as part of the diet. Supplementation with calcium may be associated with an increased risk of MI in people with dietary calcium intake above 805 mg daily, but not in those with dietary calcium intake below 805 mg daily (17482). To minimize the possible risk of CVD, CHD, or MI, advise patients not to consume more than the recommended daily intake of 1000-1200 mg and to consider total calcium intake from both dietary and supplemental sources (17484). While dietary intake of calcium is preferred over supplemental intake, advise patients who require calcium supplements to take calcium along with vitamin D, as this combination does not appear to be associated with an increased risk of MI (93533).
Rarely, calcium intake can increase the risk of calciphylaxis, which usually occurs in patients with kidney failure. Calciphylaxis is the deposition of calcium phosphate in arterioles, which causes skin ulcers and skin necrosis. In a case report, a 64-year-old female with a history of neck fracture, sepsis, and ischemic colitis presented with painful leg ulcers due to calciphylaxis. She discontinued calcium and vitamin D supplementation and was treated with sodium thiosulfate and supportive care (95816).
Gastrointestinal ...Orally, calcium can cause belching, flatulence, nausea, gastrointestinal discomfort, and diarrhea (1824,1843,12950,38803). Although constipation is frequently cited as an adverse effect of calcium, there is no scientific substantiation of this side effect (1824,1843,1844,1845,12950,38978). Calcium carbonate has been reported to cause acid rebound, but this is controversial (12935,12936).
Oncologic ...There is some concern that very high doses of calcium might increase the risk of prostate cancer. Some epidemiological evidence suggests that consuming over 2000 mg/day of dietary calcium might increase the risk for prostate cancer (4825,12949). Additional research suggests that calcium intake over 1500 mg/day might increase the risk of advanced prostate cancer and prostate cancer mortality (14132). Consumption of dairy products has also been weakly linked to a small increase in prostate cancer risk (98894). However, contradictory research suggests no association between dietary intake of calcium and overall prostate cancer risk (14131,14132,104630). More evidence is needed to determine the effect of calcium, if any, on prostate cancer risk.
Renal ...Kidney stones have been reported in individuals taking calcium carbonate 1500 mg daily in combination with vitamin D 2000 IU daily for 4 years (93943).
General
...Orally, choline is well tolerated when used appropriately.
Adverse effects have been reported with doses exceeding the tolerable upper intake level (UL) of 3.5 grams daily.
Most Common Adverse Effects:
Orally: Fishy body odor. At high doses of at least 9 grams daily, choline has been reported to cause diarrhea, nausea, salivation, sweating, and vomiting.
Cardiovascular ...Orally, doses of choline greater than 7. 5 grams daily may cause low blood pressure (94648).
Gastrointestinal ...Orally, large doses of choline can cause nausea, vomiting, salivation, and anorexia (42275,91231). Gastrointestinal discomfort has reportedly occurred with doses of 9 grams daily, while gastroenteritis has reportedly occurred with doses of 32 grams daily (42291,42310). Doses of lecithin 100 grams standardized to 3.5% choline have reportedly caused diarrhea and fecal incontinence (42312).
Genitourinary ...Orally, large doses of choline greater than 9 grams daily have been reported to cause urinary incontinence (42291).
Neurologic/CNS ...Orally, high intake of choline may cause sweating due to peripheral cholinergic effects (42275).
Oncologic ...In one population study, consuming large amounts of choline was associated with an increased risk of colorectal cancer in females, even after adjusting for red meat intake (14845). However, more research is needed to confirm this finding.
Psychiatric ...Orally, large doses of choline (9 grams daily) have been associated with onset of depression in patients taking neuroleptics. Further research is needed to clarify this finding (42270).
Other ...Orally, choline intake may cause a fishy body odor due to intestinal metabolism of choline to trimethylamine (42285,42275,42310,92111,92112).
General
...Orally, chromium is generally well tolerated.
Most Common Adverse Effects:
Orally: Gastrointestinal irritation, headaches, insomnia, irritability, mood changes.
Serious Adverse Effects (Rare):
Orally: Rare cases of kidney and liver damage, rhabdomyolysis, and thrombocytopenia have been reported.
Dermatologic
...Orally, chromium-containing supplements may cause acute generalized exanthematous pustulosis (42561), skin rashes (42679), and urticaria (17224).
Also, chromium picolinate or chromium chloride may cause systemic contact dermatitis when taken orally, especially in patients with contact allergy to chromium (6624,90058). In one clinical study, a patient taking chromium nicotinate 50 mcg daily reported itchy palms that improved after the intervention was discontinued. It is unclear of this effect was due to the chromium or another factor (95096).
Topically, hexavalent chromium, which can be present in some cement, leather products, or contaminated soil, may cause allergic contact dermatitis (42645,42789,90060,90064,110606).
A case of lichen planus has been reported for a patient following long-term occupational exposure to chromium (42688).
Endocrine ...Orally, cases of hypoglycemia have been reported for patients taking chromium picolinate 200-1000 mcg daily alone or 200-300 mcg two or three times weekly in combination with insulin (42672,42783). Chromium picolinate has also been associated with weight gain in young females who do not exercise and in those following a weight-lifting program (1938).
Gastrointestinal
...Orally, chromium in the form of chromium picolinate, chromium polynicotinate, chromium-containing brewer's yeast, or chromium-containing milk powder may cause nausea, vomiting, diarrhea, decreased appetite, constipation, flatulence, or gastrointestinal upset (14325,42594,42607,42622,42643,42679).
Long-term exposure to heavy metals, including chromium, has been associated with increased risk of gallbladder disease and cancer (42682,42704).
Genitourinary ...Orally, chromium polynicotinate has been associated with disrupted menstrual cycles in patients taking the supplement to prevent weight gain during smoking cessation (42643).
Hematologic ...Anemia, hemolysis, and thrombocytopenia were reported in a 33 year-old female taking chromium picolinate 1200-2400 mcg daily for 4-5 months (554). The patient received supportive care, blood product transfusions, and hemodialysis and was stabilized and discharged a few days later. Lab values were normal at a one-year follow-up.
Hepatic ...Liver damage has been reported for a 33-year-old female taking chromium picolinate 1200 mcg daily for 4-5 months (554). Also, acute hepatitis has been reported in a patient taking chromium polynicotinate 200 mcg daily for 5 months (9141). Symptoms resolved when the product was discontinued. Two cases of hepatotoxicity have been reported in patients who took a specific combination product (Hydroxycut), which also contained chromium polynicotinate in addition to several herbs (13037).
Musculoskeletal ...Acute rhabdomyolysis has been reported for a previously healthy 24-year-old female who ingested chromium picolinate 1200 mcg over a 48-hour time period (42786). Also, chromium polynicotinate has been associated with leg pain and paresthesia in patients taking the supplement to prevent weight gain during smoking cessation (42643).
Neurologic/CNS ...Orally, chromium picolinate may cause headache, paresthesia, insomnia, dizziness, and vertigo (6860,10309,14325,42594). Vague cognitive symptoms, slowed thought processes, and difficulty driving occurred on three separate occasions in a healthy 35-year-old male after oral intake of chromium picolinate 200-400 mcg (42751). Transient increases in dreaming have been reported in three patients with dysthymia treated with chromium picolinate in combination with sertraline (2659). A specific combination product (Hydroxycut) containing chromium, caffeine, and ephedra has been associated with seizures (10307). But the most likely causative agent in this case is ephedra.
Psychiatric ...Orally, chromium picolinate has been associated with irritability and mood changes in patients taking the supplement to lose weight, while chromium polynicotinate has been associated with agitation and mood changes in patients taking the supplement to prevent weight gain during smoking cessation (6860,42643).
Renal
...Orally, chromium picolinate has been associated with at least one report of chronic interstitial nephritis and two reports of acute tubular necrosis (554,1951,14312).
Laboratory evidence suggests that chromium does not cause kidney tissue damage even after long-term, high-dose exposure (7135); however, patient- or product-specific factors could potentially increase the risk of chromium-related kidney damage. More evidence is needed to determine what role, if any, chromium has in potentially causing kidney damage.
Intravenously, chromium is associated with decreased glomerular filtration rate (GFR) in children who receive long-term chromium-containing total parenteral nutrition - TPN (11787).
Topically, burns caused by chromic acid, a hexavalent form of chromium, have been associated with acute chromium poisoning with acute renal failure (42699). Early excision of affected skin and dialysis are performed to prevent systemic toxicity.
Other ...Another form of chromium, called hexavalent chromium, is unsafe. This type of chromium is a by-product of some manufacturing processes. Chronic exposure can cause liver, kidney, or cardiac failure, pulmonary complications, anemia, and hemolysis (9141,11786,42572,42573,42699). Occupational inhalation of hexavalent chromium can cause ulceration of the nasal mucosa and perforation of the nasal septum, and has been associated with pneumoconiosis, allergic asthma, cough, shortness of breath, wheezing, and increased susceptibility to respiratory tract cancer and even stomach and germ cell cancers (42572,42573,42601,42610,42636,42667,42648,42601,42788,90056,90066). Although rare, cases of interstitial pneumonia associated with chromium inhalation have been reported. Symptoms resolved with corticosteroid treatment (42614).
General ...There is no reliable evidence regarding the safety of evodia from clinical trials. In animal studies, evodia has induced QT prolongation and Torsade de pointes (97035).
Cardiovascular ...In animal studies, evodia acts as a proarrhythmic agent with a dose-dependent effect. Evodia infusion has resulted in QT prolongation and Torsade de pointes (97035). It is not clear what dose of evodia, if any, is required to produce a similar effect in humans.
General
...Orally or intravenously, iron is generally well tolerated when used appropriately.
Most Common Adverse Effects:
Orally: Abdominal pain, constipation, diarrhea, gastrointestinal irritation, nausea, and vomiting.
Serious Adverse Effects (Rare):
Orally: Case reports have raised concerns about oral or gastric ulcerations.
Intravenously: Case reports have raised concerns about hypophosphatemia and osteomalacia.
Cardiovascular
...There is debate regarding the association between coronary heart disease (CHD) or myocardial infarction (MI) and high iron intake or high body iron stores.
Some observational studies have reported that high body iron stores are associated with increased risk of MI and CHD (1492,9542,9544,9545,15175). Some observational studies reported that only high heme iron intake from dietary sources such as red meat are associated with increased risk of MI and CHD (1492,9546,15174,15205,15206,91180). However, the majority of research has found no association between serum iron levels and cardiovascular disease (1097,1099,9543,9547,9548,9549,9550,56469,56683).
There is one case of Kounis syndrome, also referred to as allergic angina or allergic myocardial infarction, in a 39-year-old female patient without previous coronary artery disease given intravenous ferric carboxymaltose. The patient experienced anaphylactic symptoms, including headache, abdominal pain, and breathing difficulties, 3 minutes after starting the infusion. She was further diagnosed with non-ST-elevation myocardial infarction (112607).
Dermatologic ...Cutaneous hemosiderosis, or skin staining, has been reported following intravenous iron infusion in various case reports. Most of these cases are due to extravasation following iron infusion (112605,112611). In one case, extravasation has occurred following iron derisomaltose infusion in a 41-year-old female with chronic kidney disease (112605). Rarely, diffuse cutaneous hermosiderosis has occurred. In one case, a 31-year-old female with excessive sweating developed cutaneous hemosiderosis in the armpits following an intravenous iron polymaltose infusion (112611).
Endocrine ...Population research in females shows that higher ferritin levels are associated with an approximately 1. 5-fold higher odds of developing gestational diabetes. Increased dietary intake of heme-iron, but not non-heme iron, is also associated with an increased risk for gestational diabetes. The effects of iron supplementation could not be determined from the evaluated research (96618). However, in a sub-analysis of a large clinical trial in pregnant adults, daily supplementation with iron 100 mg from 14 weeks gestation until delivery did not affect the frequency or severity of glucose intolerance or gestational weight gain (96619).
Gastrointestinal
...Orally, iron can cause dry mouth, gastrointestinal irritation, heartburn, abdominal pain, constipation, diarrhea, nausea, or vomiting (96621,102864,104680,104684,110179,110185,110188,110189,110192).
These adverse effects are uncommon at doses below the tolerable upper intake level (UL) of 45 mg per day of elemental iron in adults with normal iron stores (7135). Higher doses can be taken safely in adults with iron deficiency, but gastrointestinal side effects may occur (1095,20118,20119,56698,102864). Taking iron supplements with food seems to reduce gastrointestinal side effects (7135). However, food can also significantly reduce iron absorption. Iron should be taken on an empty stomach, unless it cannot be tolerated.
There are several formulations of iron products such as ferrous sulfate, ferrous gluconate, ferrous fumarate, and others. Manufacturers of some formulations, such as polysaccharide-iron complex products (Niferex-150, etc), claim to be better tolerated than other formulations; however, there is no reliable evidence to support this claim. Gastrointestinal tolerability relates mostly to the elemental iron dose rather than the formulation (17500).
Enteric-coated or controlled-release iron formulations might reduce nausea for some patients, however, these products also have lower absorption rates (17500).
Liquid oral preparations can blacken and stain teeth (20118).
Iron can also cause oral ulcerations and ulcerations of the gastric mucosa (56684,91182,96622,110179). In one case report, an 87-year-old female with Alzheimer disease experienced a mucosal ulceration, possibly due to holding a crushed ferrous sulfate 80 mg tablet in the mouth for too long prior to swallowing (91182). The ulceration was resolved after discontinuing iron supplementation. In another case report, a 76-year old male suffered gastric mucosal injury after taking a ferrous sulfate tablet daily for 4 years (56684). In a third case report, a 14-year-old female developed gastritis involving symptoms of upper digestive hemorrhage, nausea, melena, and stomach pain. The hemorrhage was attributed to supplementation with ferrous sulfate 2 hours after meals for the prior 2 weeks (96622). In one case report, a 43-year old female developed atrophic gastritis with non-bleeding ulcerations five days after starting oral ferrous sulfate 325 mg twice daily (110179).
Intravenously, iron can cause gastrointestinal symptoms sch as nausea (104684,110192).
Immunologic
...Although there is some clinical research associating iron supplementation with an increased rate of malaria infection (56796,95432), the strongest evidence to date does not support this association, at least for areas where antimalarial treatment is available (95433,96623).
In an analysis of 14 trials, iron supplementation was not associated with an increased risk of malaria (96623). In a sub-analysis of 7 preliminary clinical studies, the effect of iron supplementation was dependent upon the access to services for antimalarial treatment. In areas where anemia is common and services are available, iron supplementation is associated with a 9% reduced risk of clinical malaria. In an area where services are unavailable, iron supplementation was associated with a 16% increased risk in malaria incidence (96623). The difference in these findings is likely associated with the use of malaria prevention methods.
A meta-analysis of clinical studies of all patient populations shows that administering IV iron, usually iron sucrose and ferric carboxymaltose, increases the risk of infection by 16% when compared with oral iron or no iron. However, sub-analyses suggest this increased risk is limited to patients with inflammatory bowel disease (IBD) (110186).
Intravenously, iron has rarely resulted in allergic reactions, including anaphylactoid reactions (110185,110192,112606,112607). There is one case of Kounis syndrome, also referred to as allergic angina or allergic myocardial infarction, in a 39-year-old female patient without previous coronary artery disease given intravenous ferric carboxymaltose. The patient experienced anaphylactic symptoms, including headache, abdominal pain, and breathing difficulties, 3 minutes after starting the infusion. She was further diagnosed with non-ST-elevation myocardial infarction (112607).
Musculoskeletal ...Intravenously, iron rarely results in osteomalacia related to hypophosphatemia (112609). At least 2 cases exist of hypophosphatemic osteomalacia. In one case, a 70-year-old male with a genetic hemorrhagic disorder infused with ferric carboxymaltose developed lower limb pain with hypophosphatemia and diffuse bone demineralization in the feet (112609). In a second case, a 61-year-old male developed femoral neck insufficiency fractures following repeated ferric carboxymaltose transfusions for anemia related to vascular malformation in the bowel (112603). Severe hypophosphatemia requiring intravenous phosphate in the absence of osteomalacia has also occurred following intravenous ferric carboxymaltose (112608,112610).
Oncologic
...There is a debate regarding the association between high levels of iron stores and cancer.
Data are conflicting and inconclusive (1098,1099,1100,1102). Epidemiological studies suggest that increased body iron stores may increase the risk of cancer or general mortality (56703).
Occupational exposure to iron may be carcinogenic (56691). Oral exposure to iron may also be carcinogenic. Pooled analyses of population studies suggest that increasing the intake of heme iron increases the risk of colorectal cancer. For example, increasing heme iron intake by 1 mg/day is associated with an 11% increase in risk (56699,91185).
Other ...Intravenously, sodium ferric gluconate complex (SFGC) caused drug intolerance reactions in 0. 4% of hemodialysis patients including 2 patients with pruritus and one patient each with anaphylactoid reaction, hypotension, chills, back pain, dyspnea/chest pain, facial flushing, rash and cutaneous symptoms of porphyria (56527).
General
...Orally and intravenously, L-carnitine is generally well tolerated.
Most Common Adverse Effects:
All routes of administration: Abdominal cramps, abdominal pain, diarrhea, gastritis, heartburn, nausea, reduced appetite, and vomiting. A fish-like body odor has also been reported.
Serious Adverse Effects (Rare):
All routes of administration: Seizures.
Cardiovascular ...According to population research, plasma L-carnitine levels are associated with increased risk of cardiovascular disease and major cardiac events (90635). However, oral supplementation with L-carnitine does not appear to be associated with an increased risk of cardiovascular disease. In fact, a meta-analysis of clinical research shows that L-carnitine supplementation is associated with a reduction in all-cause mortality, as well as ventricular arrhythmias and the development of angina and does not increase the development of heart failure or myocardial reinfarction (59037). Also, another meta-analysis suggests that L-carnitine does not affect mortality or cardiovascular outcomes in patients with a previous myocardial infarction (90630).
Dermatologic ...Orally, L-carnitine has been reported to cause skin rash in a small number of cases (16105,91724). Two patients in a hair growth study using topical carnitine reported mild itching and increased dandruff, while a third reported strong itching with reddish bumps and a burning sensation (58390). When a specific formulation containing L-carnitine, licochalcone, and 1,2-decanediol was applied to the face, mild skin dryness and tightness was reported by 12% of volunteers, compared with 4% to 8% of those in the vehicle-only control group (26493).
Gastrointestinal ...Orally and intravenously, L-carnitine has been associated with nausea, epigastric discomfort, vomiting, abdominal cramps, heartburn, gastritis, anorexia, and diarrhea (3616,3624,59030,95069,95070,101562,107410,111870,111887,111891). Orally, diarrhea or colitis symptoms (1433,3630,16105,16107,16111,23437,58523,58554,59020,90623), nausea and abdominal pain (16105,16106,26499,58169,58392,58554,90623,90634), indigestion (26703), and constipation (58523) have been reported in various clinical trials.
Hematologic ...In one case report, L-carnitine 990 mg twice daily was started in a female presenting to hospital with valproic acid toxicity. Blood phosphorous levels subsequently fell from 2.3 mg/dL to 1.3 mg/dL over 4 days. After discontinuation of L-carnitine, blood phosphorus levels increased to 1.8 mg/dL. The authors suggested that the role of L-carnitine in improved protein metabolism may play a role in the declining levels of phosphorous in the blood and increased risk of hypophosphatemia (90628).
Neurologic/CNS ...Orally or intravenously, L-carnitine has been associated with seizures (3616). Orally, use of L-carnitine in clinical trials has resulted in headache, although this event is rare (58554,95070,111891). L-carnitine may also cause agitation (95070).
Other ...Orally or intravenously, L-carnitine has been associated with a fish-like body odor (1433,3616,58166,59854,90623). One of its metabolites, trimethylamine N-oxide, can cause the urine, breath, and sweat to have a fishy odor (12756,58664).
General
...Orally, a thorough evaluation of safety outcomes for raspberry ketone has not been conducted.
Structurally, raspberry ketone resembles synephrine, a known stimulant agent.
Cardiovascular ...Structurally, raspberry ketone resembles synephrine, a known stimulant agent. Although not well studied in humans, stimulant-related side effects are possible. Orally, cases of heart palpitations, tachycardia, elevated blood pressure, coronary vasospasm are reported after taking raspberry ketone (17961,112386,112400). In one case report, pulseless electrical activity arrest followed by resistant polymorphic ventricular tachycardia occurred in a patient taking raspberry ketone. The arrhythmia resolved after numerous defibrillation shocks and placement of a temporary transvenous pacemaker with overdrive pacing (112386). In another case report, 5 episodes of ST elevation occurred over 2 days following ingestion of raspberry ketone (112400).
Neurologic/CNS ...Structurally, raspberry ketone resembles synephrine, a known stimulant agent. Although not well studied in humans, stimulant-related side effects are possible. Two case reports describe symptoms of sweating, diarrhea, and feelings of shakiness after oral use of raspberry ketone (17961,112400).
General
...Orally, sodium is well tolerated when used in moderation at intakes up to the Chronic Disease Risk Reduction (CDRR) intake level.
Topically, a thorough evaluation of safety outcomes has not been conducted.
Serious Adverse Effects (Rare):
Orally: Worsened cardiovascular disease, hypertension, kidney disease.
Cardiovascular
...Orally, intake of sodium above the CDRR intake level can exacerbate hypertension and hypertension-related cardiovascular disease (CVD) (26229,98176,100310,106263).
A meta-analysis of observational research has found a linear association between increased sodium intake and increased hypertension risk (109398). Observational research has also found an association between increased sodium salt intake and increased risk of CVD, mortality, and cardiovascular mortality (98177,98178,98181,98183,98184,109395,109396,109399). However, the existing research is unable to confirm a causal relationship between sodium intake and increased cardiovascular morbidity and mortality; high-quality, prospective research is needed to clarify this relationship (100312). As there is no known benefit with increased salt intake that would outweigh the potential increased risk of CVD, advise patients to limit salt intake to no more than the CDRR intake level (100310).
A reduction in sodium intake can lower systolic blood pressure by a small amount in most individuals, and diastolic blood pressure in patients with hypertension (100310,100311,106261). However, post hoc analysis of a small crossover clinical study in White patients suggests that 24-hour blood pressure variability is not affected by high-salt intake compared with low-salt intake (112910). Additionally, the available research is insufficient to confirm that a further reduction in sodium intake below the CDRR intake level will lower the risk for chronic disease (100310,100311). A meta-analysis of clinical research shows that reducing sodium intake increases levels of total cholesterol and triglycerides, but not low-density lipoprotein (LDL) cholesterol, by a small amount (106261).
It is unclear whether there are safety concerns when sodium is consumed in amounts lower than the adequate intake (AI) levels. Some observational research has found that the lowest levels of sodium intake might be associated with increased risk of death and cardiovascular events (98181,98183). However, this finding has been criticized because some of the studies used inaccurate measures of sodium intake, such as the Kawasaki formula (98177,98178,101259). Some observational research has found that sodium intake based on a single 24-hour urinary measurement is inversely correlated with all-cause mortality (106260). The National Academies Consensus Study Report states that there is insufficient evidence from observational studies to conclude that there are harmful effects from low sodium intake (100310).
Endocrine ...Orally, a meta-analysis of observational research has found that higher sodium intake is associated with an average increase in body mass index (BMI) of 1. 24 kg/m2 and an approximate 5 cm increase in waist circumference (98182). It has been hypothesized that the increase in BMI is related to an increased thirst, resulting in an increased intake of sugary beverages and/or consumption of foods that are high in salt and also high in fat and energy (98182). One large observational study has found that the highest sodium intake is not associated with overweight or obesity when compared to the lowest intake in adolescents aged 12-19 years when intake of energy and sugar-sweetened beverages are considered (106265). However, in children aged 6-11 years, usual sodium intake is positively associated with increased weight and central obesity independently of the intake of energy and/or sugar-sweetened beverages (106265).
Gastrointestinal ...In one case report, severe gastritis and a deep antral ulcer occurred in a patient who consumed 16 grams of sodium chloride in one sitting (25759). Chronic use of high to moderately high amounts of sodium chloride has been associated with an increased risk of gastric cancer (29405).
Musculoskeletal
...Observational research has found that low sodium levels can increase the risk for osteoporosis.
One study has found that low plasma sodium levels are associated with an increased risk for osteoporosis. Low levels, which are typically caused by certain disease states or chronic medications, are associated with a more than 2-fold increased odds for osteoporosis and bone fractures (101260).
Conversely, in healthy males on forced bed rest, a high intake of sodium chloride (7.7 mEq/kg daily) seems to exacerbate disuse-induced bone and muscle loss (25760,25761).
Oncologic ...Population research has found that high or moderately high intake of sodium chloride is associated with an increased risk of gastric cancer when compared with low sodium chloride intake (29405). Other population research in patients with gastric cancer has found that a high intake of sodium is associated with an approximate 65% increased risk of gastric cancer mortality when compared with a low intake. When zinc intake is taken into consideration, the increased risk of mortality only occurred in those with low zinc intake, but the risk was increased to approximately 2-fold in this sub-population (109400).
Pulmonary/Respiratory ...In patients with hypertension, population research has found that sodium excretion is modestly and positively associated with having moderate or severe obstructive sleep apnea. This association was not found in normotensive patients (106262).
Renal ...Increased sodium intake has been associated with impaired kidney function in healthy adults. This effect seems to be independent of blood pressure. Observational research has found that a high salt intake over approximately 5 years is associated with a 29% increased risk of developing impaired kidney function when compared with a lower salt intake. In this study, high salt intake was about 2-fold higher than low salt intake (101261).
