Below is general information about the safety of the known ingredients contained in the product LipidEnz. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
LIKELY SAFE ...when used orally in amounts commonly found in foods. Artichoke has Generally Recognized As Safe status (GRAS) for use in foods in the US (4912).
POSSIBLY SAFE ...when used orally and appropriately in medicinal amounts. Artichoke extract has been used with apparent safety at doses up to 3200 mg daily for up to 12 weeks (6282,15204,52235,91475,91478,100934). Artichoke leaf powder has been used with apparent safety at a dose of 1000 mg daily for up to 8 weeks (104133). Cynarin, a constituent in artichoke extract, has been used with apparent safety at daily doses of 750 mg daily for up to 3 months or 60 mg daily for up to 7 months (1423,1424,52222,52223,52236).
PREGNANCY AND LACTATION:
There is insufficient reliable information available about the safety of artichoke when used in medicinal amounts during pregnancy or lactation; avoid amounts greater than those found in foods.
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
when used orally and appropriately in amounts not exceeding the daily adequate intake (AI) levels by age: 0-6 months, 0.
2 mcg; 7-12 months, 5.5 mcg; 1-3 years, 11 mcg; 4-8 years, 15 mcg; males 9-13 years, 25 mcg; males 14-18 years, 35 mcg; females 9-13 years, 21 mcg; females 14-18 years, 24 mcg (7135). 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 garcinia extract when used orally. However, there is some concern about liver toxicity. There are numerous case reports of elevated liver enzymes and symptoms of liver toxicity in patients who have taken garcinia alone or in combination with other ingredients for as little as one week. In at least two reports, hepatotoxicity occurred in patients who were taking garcinia alone. Most other reports occurred in patients taking multi-ingredient products (13037,53511,93380,93381,93384,93385,93392,93393,93394,96535)(102544,102545,111241).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally and appropriately. Garlic has been used safely in clinical studies lasting up to 7 years without reports of significant toxicity (1873,4782,4783,4784,4785,4786,4787,4789,4790,4797)(4798,6457,6897,14447,96008,96009,96014,102016,102670,103479)(107238,107239,107352,108607,110722,111763).
POSSIBLY SAFE ...when used topically. Garlic-containing gels, lipid-soluble garlic extracts, garlic pastes, and garlic mouthwashes have been safely used in clinical research for up to 3 months (4766,4767,8019,15030,51330,51386). ...when used intravaginally. A vaginal cream containing garlic and thyme has been safely used nightly for 7 nights (88387).
POSSIBLY UNSAFE ...when raw garlic is used topically (585). Raw garlic might cause severe skin irritation when applied topically.
PREGNANCY: LIKELY SAFE
when used orally in amounts commonly found in foods (3319).
PREGNANCY: POSSIBLY UNSAFE
when used orally in medicinal amounts.
Garlic is reported to have abortifacient activity (11020). One study also suggests that garlic constituents are distributed to the amniotic fluid after a single dose of garlic (4828). However, there are no published reports of garlic adversely affecting pregnancy. In clinical research, garlic 800 mg daily was used during the third trimester of pregnancy with no reported adverse outcomes (9201,51626). There is insufficient reliable information available about the safety of topical garlic during pregnancy.
LACTATION: LIKELY SAFE
when used orally in amounts commonly found in foods (3319).
LACTATION: POSSIBLY UNSAFE
when used orally in amounts greater than those found in foods.
Several small studies suggest that garlic constituents are secreted in breast milk, and that nursing infants of mothers consuming garlic are prone to extended nursing (3319,4829,4830). There is insufficient reliable information available about the safety of topical garlic during lactation.
CHILDREN: POSSIBLY SAFE
when used orally and appropriately for up to 8 weeks.
Garlic extract 300 mg three times daily has been used with apparent safety for up 8 weeks in children ages 8-18 years (4796). There is insufficient reliable information available about the safety of garlic when used over longer durations or in higher doses.
CHILDREN: POSSIBLY UNSAFE
when raw garlic is used topically.
Raw garlic might cause severe skin irritation when applied topically (585,51210).
POSSIBLY SAFE ...when the prepared gum resin is used orally and appropriately. It has been used with apparent safety in clinical trials for up to 24 weeks (3267,3268,10371). There is insufficient reliable information available about the safety of guggul when used topically.
PREGNANCY: LIKELY UNSAFE
when used orally; avoid using.
Guggul gum resin appears to stimulate menstrual flow and the uterus (12).
LACTATION:
Insufficient reliable information available; avoid using.
There is insufficient reliable information available about the safety of lipase.
CHILDREN: POSSIBLY UNSAFE
when recombinant human bile salt-stimulated lipase (rhBSSL) is used orally by premature infants.
Adding rhBSSL to infant formula or pasteurized breast milk increases the risk for serious gastrointestinal adverse effects in premature infants (101940).
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
Below is general information about the interactions of the known ingredients contained in the product LipidEnz. Some ingredients may not be listed. This information does NOT represent a recommendation for or a test of this specific product as a whole.
Theoretically, artichoke leaf extract may increase the risk of hypoglycemia when taken with antidiabetes drugs.
Details
A meta-analysis of small clinical studies shows that taking artichoke leaf extract for 8-12 weeks can modestly reduce fasting plasma glucose when compared with placebo (105768).
|
Theoretically, artichoke leaf extract may increase the risk of hypotension when taken with antihypertensive drugs.
Details
A meta-analysis of small clinical studies in patients with hypertension shows that taking artichoke can reduce systolic blood pressure by around 3 mmHg and diastolic blood pressure by around 2 mmHg when compared with placebo (105767).
|
Theoretically, artichoke might increase serum levels of drugs metabolized by CYP2B6.
Details
In vitro research shows that artichoke leaf extract inhibits CYP2B6 activity (97717). However, this interaction has not been reported in humans.
|
Theoretically, artichoke might increase serum levels of drugs metabolized by CYP2C19.
Details
In vitro research shows that artichoke leaf extract inhibits CYP2C19 activity (97717). However, this interaction has not been reported in humans.
|
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, hydroxycitric acid (HCA), the main active ingredient in garcinia, might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs.
Details
HCA inhibits platelet aggregation in vitro. The inhibitory effect seems to be greater in platelets extracted from diabetic subjects than non-diabetic subjects (26862).
|
Theoretically, hydroxycitric acid (HCA), the main active ingredient in garcinia, might have additive effects with antidiabetes drugs and increase the risk of hypoglycemia.
Details
|
Theoretically, concomitant use with other potentially hepatotoxic drugs might increase the risk of developing liver damage.
Details
There have been reports of acute hepatitis with elevated liver enzymes associated with garcinia, when taken alone or in combination with other ingredients (13037,53511,93380,93381,93384,93392,93393,93394,102544,102545). Case reports collected from the Drug Induced Liver Injury Network suggest this risk may be greater in people who carry the HLA B*35:01 allele (108401).
|
Theoretically, combining garcinia with other serotonergic drugs might increase the risk of serotonergic side effects, including serotonin syndrome.
Details
In one report, a patient experienced serotonin syndrome after taking garcinia extract (60% hydroxycitric acid) 1000 mg daily in combination with escitalopram 20 mg, which had been taken for a year. The patient was switched to sertraline 50 mg daily and again experienced serotonin syndrome (23545).
|
Garlic may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Details
|
Theoretically, taking garlic with antidiabetes drugs might increase the risk of hypoglycemia.
Details
|
Theoretically, taking garlic with antihypertensive drugs might increase the risk of hypotension.
Details
|
Theoretically, garlic might decrease levels and effects of atazanavir.
Details
In a case report, a patient consuming six stir-fried garlic cloves three times weekly developed suboptimal atazanavir levels and increases in HIV viral load. While the exact cause of this interaction is unclear, there is speculation that garlic might decrease the intestinal absorption of atazanavir or increase its metabolism by inducing cytochrome P450 3A4 (CYP3A4) (88388). Until more is known, advise patients not to consume large amounts of garlic while taking atazanavir.
|
Garlic might increase levels of drugs metabolized by CYP2E1.
Details
Clinical research suggests garlic oil can inhibit the activity of CYP2E1 by 39% (10847). Use garlic oil cautiously in patients taking drugs metabolized by these enzymes.
|
Theoretically, garlic products containing allicin might induce intestinal CYP3A4 and inhibit hepatic CYP3A4. This may increase or decrease levels of drugs metabolized by CYP3A4.
Details
Some human research suggests that garlic may induce INTESTINAL CYP3A4, reducing levels of drugs metabolized by this enzyme. This is primarily based on a study showing that taking a specific allicin-containing garlic product (GarliPure Maximum Allicin Formula, Natrol Inc.) twice daily for 3 days reduces saquinavir levels by approximately 50%. It is speculated that the allicin constituent induced CYP3A4 in the gut mucosa (7027,93578). Another study shows that giving docetaxel intravenously, bypassing the CYP3A4 enzymes in the gut mucosa, along with the same specific garlic product for 12 consecutive days, does not affect docetaxel levels (17221). Conversely, there is concern that garlic may inhibit HEPATIC CYP3A4. In a single case report, increased tacrolimus levels and liver injury occurred in a liver transplant patient after taking a specific garlic supplement (Garlicin Cardio, Nature's Way) at up to three times the manufacturer recommended dose for 7 days (96010). Several other studies have evaluated the impact of other garlic formulations on CYP3A4 substrates and have found no effect. Most of the products in these studies provided little or no allicin (10335,10847,15031,94506).
|
Theoretically, garlic might decrease levels of isoniazid.
Details
Animal research suggests that an aqueous extract of garlic reduces isoniazid levels by about 65%. Garlic reduced the maximum concentration (Cmax) and area under the curve (AUC), but not the half-life, of isoniazid. This suggests that garlic extract might inhibit isoniazid absorption across the intestinal mucosa (15031); however, the exact mechanism of this potential interaction is not known.
|
Theoretically, garlic products containing allicin might decrease levels of PIs.
Details
Protease inhibitors are metabolized by cytochrome P450 3A4 (CYP3A4) isoenzymes. There is concern that garlic products containing allicin might induce intestinal CYP3A4, reducing plasma levels of protease inhibitors. This is primarily based on a study showing that taking a specific garlic product (GarliPure Maximum Allicin Formula, Natrol Inc.) twice daily for 3 days reduces levels of saquinavir, a PI, by approximately 50%. It is speculated that the allicin constituent induce CYP3A4 in the gut mucosa (7027,93578). Several studies have evaluated the impact of other garlic formulations on CYP3A4 substrates and have found no effect. Most of the products in these studies provided little or no allicin (10335,10847,15031,94506).
|
Theoretically, garlic containing allicin might decrease levels of saquinavir.
Details
Saquinavir is a substrate of cytochrome P450 3A4 (CYP3A4) isoenzymes. There is concern that garlic products containing allicin might induce intestinal CYP3A4 and cause subtherapeutic levels of saquinavir. This is primarily based on a pharmacokinetic study showing that taking a specific garlic product (GarliPure Maximum Allicin Formula, Natrol Inc.) twice daily for 3 days reduces saquinavir levels by approximately 50%. It is speculated that the allicin constituent induces CYP3A4 in the gut mucosa (7027,93578). Several pharmacokinetic studies have evaluated the impact of other garlic formulations on CYP3A4 substrates and have found no effect. Most of the products in these studies provided little or no allicin (10335,10847,15031,94506). Until more is known about this potential interaction, use garlic containing allicin cautiously in patients taking saquinavir.
|
Theoretically, taking garlic with sofosbuvir might decrease its effectiveness.
Details
Animal research in rats shows that giving aged garlic extract 120 mg/kg orally daily for 14 days decreases the area under the concentration time curve (AUC) after a single sofosbuvir dose of 40 mg/kg by 36%, increases the clearance by 63%, and decreases the plasma concentrations at 1 and 8 hours by 35% and 58%, respectively. This interaction is hypothesized to be due to induction of intestinal P-glycoprotein expression by garlic (109524).
|
Theoretically, garlic might increase levels of tacrolimus.
Details
In one case report, a liver transplant patient taking tacrolimus experienced increased tacrolimus levels and liver injury after taking a specific garlic supplement (Garlicin Cardio, Nature's Way) at up to three times the manufacturer recommended dose for 7 days. It is speculated that garlic inhibited hepatic cytochrome P450 3A4 (CYP3A4), which increased plasma levels of tacrolimus (96010).
|
Theoretically, garlic might increase the risk of bleeding with warfarin.
Details
Raw garlic and a variety of garlic extracts have antiplatelet activity and can increase prothrombin time (586,616,1874,3234,4366,4802,4803,51397). In addition, there is a report of two patients who experienced an increase in a previously stabilized international normalized ratio (INR) with concomitant garlic and warfarin use (51228,51631). However, this report has been subsequently debated due to limited clinical information. Other clinical studies have not identified an effect of garlic on INR, warfarin pharmacokinetics, or bleeding risk (15032,16416). More evidence is needed to determine the safety of using garlic with warfarin.
|
Theoretically, guggul might increase the risk of bleeding when taken with anticoagulant/antiplatelet drugs.
Details
|
Theoretically, guggul might increase the risk of adverse effects when taken with contraceptive drugs.
Details
In vitro research shows that guggul has estrogen-alpha receptor agonist activity (12444).
|
Theoretically, guggul might reduce the effects of CYP3A4 substrates.
Details
In vitro research shows that guggul constituents known as guggulsterones can induce CYP3A4 (12444).
|
Guggul might reduce the effects of diltiazem.
Details
A small pharmacokinetic study shows that concomitant use of guggul with diltiazem reduces the bioavailability of diltiazem (383).
|
Theoretically, guggul might increase the risk of adverse effects when taken with estrogens.
Details
In vitro research shows that guggul constituents known as guggulsterones have estrogen-alpha receptor agonist activity (12444).
|
Guggul might reduce the effects of propranolol.
Details
A small pharmacokinetic study shows that concomitant use of guggul with propranolol reduces the bioavailability of propranolol (383).
|
Theoretically, guggul might increase the effects and adverse effects of rosuvastatin.
Details
Animal research shows that guggul increases the bioavailability and hypolipidemic effects of rosuvastatin (109584). The mechanism of this interaction is unclear.
|
Theoretically, guggul might interfere with tamoxifen therapy.
Details
In vitro research shows that guggul has estrogen-alpha receptor agonist activity (12444).
|
Theoretically, guggul might increase the risk for adverse effects when taken with thyroid hormone therapy.
Details
Animal research suggests that guggul has thyroid-stimulating effects (8153).

Below is general information about the adverse effects of the known ingredients contained in the product LipidEnz. 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, artichoke extract seems to be well tolerated.
Most Common Adverse Effects:
Orally: Abdominal pain, diarrhea, flatulence, hunger, and nausea.
Topically: Contact dermatitis in sensitive individuals.
Serious Adverse Effects (Rare):
Orally: Anaphylaxis to artichoke inulin has been reported in individuals sensitive to inulin.
Topically: Chest tightness, cough, and dyspnea after occupational exposure in sensitive individuals.
Dermatologic
...Artichoke can cause an allergic reaction in some patients.
Patients sensitive to the Asteraceae/Compositae family may be at the greatest risk. Members of this family include ragweed, chrysanthemums, marigolds, daisies, and many other herbs. Topically, allergic contact dermatitis can occur with the use of artichoke. This has been attributed to the constituent cynaropicrin (11,52206,52226,52230). Redness in the face (11774) and sweating (91475) have been reported rarely following oral use of artichoke extract.
Occupational or airborne exposure to artichoke may also cause allergic reactions. In one case, a 52-year-old male presented with severe spongiotic dermatitis in exposed areas that was recurrent over the past 8 years. A patch test confirmed allergies to artichokes and sesquiterpene lactones, a group of allergens from the Compositae family, and the patient confirmed occupational and airborne exposure to artichokes during the time of his symptoms. The patient improved considerably after treatment with dupilumab (111565).
Gastrointestinal
...Orally, artichoke extract might increase abdominal discomfort, flatulence, diarrhea, hunger, and nausea in some patients (2562,52238,91475).
Abdominal pain and a bitter taste in the mouth were reported by a single person following oral use of a dietary supplement containing artichoke extract, as well as red yeast rice, pine bark extract, and garlic extract (89452). It is not clear if this adverse effect was due to artichoke, other ingredients, or the combination.
In one case report, the autopsy of an 84-year-old female revealed a colonic bezoar comprised of artichoke fiber and fragments. This bezoar caused complete intestinal obstruction, leading to fatal acute peritonitis. Although rare, patients who lack adequate teeth and/or who have a history of gastric surgery are at increased risk for fibrous bezoar formation (97716).
Pulmonary/Respiratory
...Following occupational exposure, allergic symptoms including dyspnea, cough, chest tightness, and asthma symptoms or exacerbation have been reported.
The effects were attributed to sensitization to artichoke. Subsequent nasal challenge with artichoke extract caused reduced nasal patency in these patients (52210,52230).
Orally, severe anaphylactic shock in response to artichoke inulin as an ingredient in commercially available products has been reported (52217). Individuals with a noted sensitivity to artichokes should consume inulin with caution. While rare, individuals with a known inulin allergy should avoid artichoke and artichoke extract.
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
...Orally, garcinia and its constituent, hydroxycitric acid (HCA), seem to be generally well tolerated in clinical research.
Most Common Adverse Effects:
Orally: Diarrhea, gastrointestinal discomfort, headache, and nausea.
Serious Adverse Effects (Rare):
Orally: Garcinia has been linked with cases of hepatotoxicity and liver failure. There have also been rare cases of mania and pancreatitis.
Cardiovascular
...There is a case report of a 48-year-old female who developed acute necrotizing eosinophilic myocarditis (ANEM) after using a garcinia supplement orally for 2.
5 weeks. On admission to hospital, she was hypotensive and had an elevated serum troponin level, progressing to fulminant heart failure, acute kidney failure, and sustained ventricular arrhythmias. She recovered after treatment with extra-corporeal membrane oxygenation (ECMO) and high-dose corticosteroids (88160). Although the patient had no prior medical history and was not taking any medications, this cannot conclusively be attributed to garcinia.
When taken orally, a specific formulation of the multi-ingredient product Hydroxycut (Iovate Health Sciences Inc.), which was available until 2009, has been associated with malignant hypertension and hypertensive retinopathy. Hydroxycut contains caffeine, garcinia, gymnema, green tea, glucomannan, guarana extract, and willow bark. The suspected causal agent is caffeine, which is dosed at 600 mg daily if Hydroxycut is taken as recommended; however, the responsibility of the other ingredients cannot be ruled out (16527).
Endocrine ...In one case report, a 56-year-old female with pre-existing diabetes, hepatitis C, and hypertension developed diabetic ketoacidosis (DKA) and pancreatitis after taking an unknown amount of garcinia and African mango for one month. Upon admission, she presented with altered mental status, elevated serum glucose and lipase, and high anion gap metabolic acidosis. After 3 days of intensive supportive care, the DKA and pancreatitis resolved. The suspected probable causal agent was garcinia; however, African mango cannot be ruled out (97341). There have been at least 3 other cases of acute pancreatitis associated with use of garcinia (unknown dose) for 2 weeks and up to 7 months in adults ages 36-82 years (105056,105058,105071).
Gastrointestinal ...Orally, garcinia and its active constituent hydroxycitric acid (HCA) have caused mild and infrequent nausea, diarrhea, and other gastrointestinal symptoms (728,11977,19153,88158,88159).
Hepatic
...Orally, garcinia and its constituent hydroxycitric acid (HCA) might cause liver toxicity.
Several cases of acute liver toxicity have been reported in patients taking garcinia supplements (93392,93393,93394,95573,102544,102545,104431,111241). Reported doses of garcinia extract range from 480-1800 mg daily, providing up to 900 mg HCA daily (93392,93394,95573,102544,104431). However, not all experts agree that HCA plays a causal role in the hepatotoxicity associated with garcinia supplements; some suggest other mechanisms may be in play, such as immune-mediated processes (95576,108401). In most cases, patients presented with a hepatocellular pattern of toxicity and symptoms of abdominal pain, coagulopathy, jaundice, and elevated transaminases after taking garcinia for several weeks to several months (93393,93394,95573,102544,102545,104431,108401,111241). In most of these cases, there was no evidence of other natural causes of liver disease, such as viral hepatitis. Some of these patients used acetaminophen at recommended doses for limited durations, suggesting that a potential synergistic effect may occur when multiple hepatotoxic agents are used concomitantly.
The Drug-Induced Liver Injury Network has identified 22 cases (11 moderate; 7 severe) of liver injury from garcinia, with 5 cases occurring with garcinia alone, 16 cases occurring in combination with green tea, and 1 case occurring in combination with ashwagandha. Clinical presentations of liver injury related to garcinia closely resemble green tea-related liver injury. Most patients (82%) presented with a hepatocellular pattern of enzyme elevations. The median age of these case reports was 35 years, 41% identified as Hispanic, and most patients were overweight but not obese. In case reports involving garcinia alone, the carrier frequency on HLAB*35:01 was 60%, which is higher than the carrier frequency found in reports of liver injury due to other supplements (19%) and in population controls (11%). Within 3 months of injury onset, 1 patient required liver transplantation and 1 patient died from liver injury (108401).
There have been at least four cases of liver failure requiring transplantation associated with garcinia supplements (93392,95573,98425,104431). In one case related specifically to garcinia, a 52-year-old female had been taking a combination product (USA Nutra Labs) providing garcinia 1000 mg daily, standardized to 60% HCA. The supplement also provided calcium 50 mg, chromium 200 mcg, and potassium 50 mg. Symptoms started within a few weeks of initiation of the product (93392). In another case, a 34-year-old Hispanic male experienced acute liver failure requiring transplant after taking a specific garcinia product (Garcinia Cambogia 5:1 Extract, Swanson Vitamins) 160 mg three times daily before meals for 5 months (95573). In other reports, one 26-year-old male and one female presented to the emergency room with liver failure after 2-7 months of taking a supplement containing garcinia and green tea, with or without whey protein, Veldt raisin, and coffea arabica (98425,104431).
There have also been numerous cases of acute liver toxicity associated with combination products containing garcinia, such as Hydroxycut (Iovate Health Sciences Inc) (13037,53511,93380,93381,93384,93385,96535,98425,104431). Available until 2009, Hydroxycut contained garcinia, green tea, chromium, caffeine, calcium, potassium, and gymnema. A currently available garcinia-containing combination product called Seryburn Day Triple has also been associated with supplement-induced liver injury. (13037,93380,93381,95570,95572,95575,111241). In most of these cases, patients had elevated levels of liver enzymes without evidence of chronic liver disease. Patients usually developed symptoms within 1-12 weeks of taking the product. The clinical pattern of liver damage was often hepatocellular. Most cases reported altered liver enzyme values including ALT, AST, bilirubin, alkaline phosphatase, and international normalized ratio. In most cases, symptoms resolved with near normalization of enzyme levels once the garcinia-containing combination product was discontinued (13037,53511,93380,93381,93384,95567,95572,95575,111241).
However, there is one report of transplant related to Hydroxycut use (93381). As the suspected causal agents, garcinia and green tea were removed from the product during reformulation in 2009 (13037,53511,93380,93381,93384). Hepatotoxicity has been reported in at least one new formulation of Hydroxycut not containing garcinia (93394). Consequently, some experts believe that there is not enough information to attribute hepatotoxicity from this product to garcinia or HCA (95576). Also, in some cases, causality of hepatotoxicity was less clear because patients were taking many other supplements and drugs (95570).There is also a report of fatal liver failure in an obese female taking montelukast while also taking two dietary supplements containing multiple ingredients, including garcinia, gymnema, chromium, bitter orange, and many others. The authors speculated that the combination of montelukast with one or more ingredients in these dietary supplements may have resulted in liver failure (93385).
Musculoskeletal ...Orally, garcinia-containing products have been associated with rhabdomyolysis. There is a case report of a patient who developed rhabdomyolysis 3 hours after ingestion of an herbal product containing ephedra, guarana, chitosan, gymnema, garcinia, and chromium (19154). Since there were multiple ingredients, the effect cannot be conclusively attributed to garcinia. Another case of rhabdomyolysis has been reported for a patient taking an undetermined formulation of Hydroxycut at a dose of 4 caplets daily, naproxen sodium 220 mg as needed for pain, dextroamphetamine daily for 5 days, and hydrocodone-acetaminophen and cyclobenzaprine for pain. Two weeks later, after stopping Hydroxycut and receiving supportive care, the rhabdomyolysis resolved. Hydroxycut was determined to be possibly associated with the rhabdomyolysis (95566). Since Hydroxycut contains multiple ingredients and garcinia content was possible but not confirmed, a causal relationship with garcinia could not be determined.
Neurologic/CNS ...Orally, garcinia and its active constituent hydroxycitric acid (HCA) may cause headache and dizziness (11977). A 35-year-old female reported ocular complications, headache, dizziness, and nausea after taking garcinia extract, providing more than 500 mg of HCA, three times daily for one week. The patient's neurologic symptoms resolved one day after discontinuing the garcinia extract (102546). It is unclear if these neurologic adverse effects were separate from or related to the patient's visual disturbances.
Ocular/Otic ...In one case, a 35-year-old female presented with ocular pain in both eyes, decreased vision in the left eye, headache, dizziness, and nausea after taking garcinia extract orally for one week. Ophthalmologic testing was consistent with adverse ocular effects, showing myopic shift with anterior chamber shallowing and swelling of retinal nerve fiber and macula. The patient reported taking a garcinia product containing hydroxycitric acid 500 mg three times daily, which was more than double the recommended dose per the product label. Symptoms resolved upon discontinuation of the garcinia extract and treatment with oral and topical steroids (102546).
Psychiatric ...Orally, garcinia supplements have been linked to several cases of mania. Typically, symptoms develop 1-8 weeks after starting garcinia. In a report of three patients, symptoms included reduced need for sleep, increased activities and spending, delusions of grandiosity, pressured speech, and agitation. Two of the patients were previously diagnosed with bipolar disorder, and use of garcinia was believed to precipitate episodes during stable phases of the disease. The third patient had no history of bipolar disorder, and use of garcinia was thought to possibly have unmasked previously undiagnosed primary bipolar disorder. In all three cases, recovery included discontinuation of garcinia (95568). In a separate case report, a 23-year-old male taking a specific combination product containing garcinia (Hydroxycut) 1-2 capsules daily for 1 month presented to the emergency room with mania. The patient had no history of bipolar disorder. Although the patient was started on risperidone and clonazepam, symptoms resolved following discontinuation of the supplement. Treatment was discontinued within 4 days of initiation, and the patient remained asymptomatic (95574). A 22-year-old female with no history of bipolar disorder developed mania and psychosis, presenting 10 days after starting Garcinia Cambogia Plus (Apex Vitality Health) 500-1500 mg daily, and Cleanse and Detox (Apex Vitality Health). The latter supplement contains raspberry ketones, licorice root, pumpkin seed, buckthorn root, Cascara sagrada, Irvingia gabonensis, rhubarb, pectin, Lactobacillus acidophilus, and aloe. Symptoms improved upon stopping the supplements and starting lithium and quetiapine (99421).
General
...Orally, garlic is generally well tolerated.
Topically, garlic seems to be well tolerated. Intravenously, there is insufficient reliable information available about adverse effects.
Most Common Adverse Effects:
Orally: Abdominal pain, body odor, flatulence, malodorous breath, and nausea. Allergic reactions in sensitive individuals.
Topically: Burns and dermatitis with fresh garlic.
Serious Adverse Effects (Rare):
Orally: Some case reports raise concerns about increased risk of bleeding with garlic.
Dermatologic
...Orally, garlic may cause pruritus (51316,51474,107239), flushing, and acne (107239).
Oral intake of a specific garlic product containing allicin (Allimax) has been associated with a case of pruritic rash (51474). Enteric-coated garlic tablets standardized to 1.5% allicin have also been associated with a case of pruritus (51316). Garlic has also been associated with a case of superficial pemphigus in a 49-year-old male with type 2 diabetes (51564). Garlic-induced oral ulcers have also been reported (51467).
Topically, garlic may cause contact dermatitis and urticaria (4833,5004,12635,51258,51265,51375,51403,51412,51459,51483)(51511,51512,51530,51616,51617,51618,111769), as well as contact cheilitis (51384). Fresh garlic may be more likely to elicit a reaction than garlic extract. Most reactions have resolved following withdrawal of garlic therapy. In one case report, applying crushed garlic on the neck to help ease a sore throat resulted in an itchy, burning, erythematous lesion in a young female patient. The lesion healed after one week of treatment with topical antibiotics, steroids, and antihistamine ointments (88390). Cases of occupational eczema or dermatitis have been reported in cooks (51303,51210), food handlers (51292), and caterers (51304). According to one case report, dermatitis appeared in chefs exposed to garlic (15033). Treatment with acitretin 25 mg daily or topical psoralen-ultraviolet A (PUVA) for 12 weeks proved effective in mitigating the symptoms. A 34-year-old female with a history of hand dermatitis and paronychia had a worsening of these conditions after peeling raw garlic. She had a positive skin patch test to fresh, raw garlic but not to any other tested allergens, and the conditions resolved when she avoided contact with garlic (105528). Topically, garlic may also cause chemical burns, usually within 12 hours of application. Second- and third-degree chemical burns have been reported in adults, children, and infants exposed to topical garlic, often as an unintended consequence of using garlic medicinally on the skin (585,4832,51226,51230,51252,51281,51377,51418,51468,51495,51536)(51558,51576,51577,88409,96006). A case of painful blisters on the soles of the feet of a 23-year-old Chinese female has been attributed to chemical burns caused by applying crushed raw garlic for 3 hours (51440). Topically, garlic may also cause hyperpigmentation, ulcers, necrotic lesions, facial flushing, and local irritation (4832,15030,51268,51269,108606). In one case report, applying crushed raw garlic to the palatal mucosa for several minutes to relieve mouth pain resulted in a chemical burn that produced a 3 cm necrotic ulcer in an adult female with trigeminal neuralgia (108606).
Gastrointestinal
...Orally, dehydrated garlic preparations or raw garlic may cause malodorous breath (51438,51444), body odor (732,1873,4784,4793,4795,4798,9201,10787,42692,49769)(51269,51316,51467,51602), abdominal pain or fullness, anorexia, diarrhea, constipation, flatulence, belching, heartburn, nausea, unpleasant taste, reflux, and bowel obstruction (1884,6457,6897,9201,49769,51269,51343,51380,51438,51442)(51450,51457,51466,51471,51474,51520,51593,51602,51623,88398)(88405,111766).
Large quantities of garlic may damage the gastrointestinal tract. In one case report, a patient taking garlic for hypertension reported odynophagia and retrosternal pain after taking garlic without any water the previous day. An esophageal lesion 3 cm in length was detected upon endoscopy. The symptoms resolved 3 days after starting a liquid diet and taking lansoprazole 30 mg twice daily and sucralfate four times daily (88389). One case of bowel obstruction was reported in a 66-year-old male who ingested an entire garlic bulb (51525). Esophageal perforation has been reported in at least 17 individuals who consumed entire garlic cloves. In one case the perforation led to mediastinitis and death (102672).
Garlic has also been associated with eosinophilic infiltration of the gastrointestinal tract. In one case report a 42-year-old female presented with symptoms of eosinophilic gastroenteritis, which included pollinosis, asthma, diarrhea, heart burn, peripheral eosinophilia, and urticaria. After stopping use of garlic and sesame, the patient improved (51441). In a case report of eosinophilic esophagitis, garlic was determined to be the causative agent in a patient with long-standing gastrointestinal symptoms. The patient had attempted to treat upper gastrointestinal symptoms as gastrointestinal reflux disease without success for many years. Skin prick testing showed a positive reaction to garlic, of which the patient noted frequent consumption. Marked symptom improvement was noted within 3 weeks of garlic avoidance (88393).
Intravenously, garlic 1 mg/kg of body weight daily diluted into 500 mL saline and administered over 4 hours has been reported to cause abdominal discomfort, vomiting, diarrhea, nausea, anorexia, flatulence, weight loss, and garlicky body odor (51462).
Clinical research suggests that patients with metabolic syndrome taking 1600 mg of powdered garlic by mouth daily for 3 months may experience improved intestinal transit time when compared with placebo, suggesting that garlic powder may reduce symptoms of constipation (110722).
Genitourinary ...Orally, garlic might cause dysuria or polyuria (51438,51450,51467).
Hematologic
...Oral use of dietary garlic or supplements containing garlic has caused platelet dysfunction, increased fibrinolytic activity, prolonged bleeding time, retrobulbar hemorrhage (bleeding behind the eye) postoperative bleeding, and spinal epidural hematoma (586,587,4801,4802,11325,51397,51473,51491,51532,51534)(51570,51584,51593,51594).
Also, a case of kidney hematoma following extracorporeal shock-wave lithotripsy (SWL) has been reported in a patient with nephrolithiasis who took aged garlic (51630). A case of increased bleeding time that complicated epistaxis management has been reported in a patient taking garlic, aspirin, and milk thistle (51426).
Intravenously, garlic has been associated with the development of thrombophlebitis at the injection site (51462).
Immunologic
...There is a case report of an immediate sensitivity reaction to oral raw garlic, resulting in wheals, in a 31-year-old female.
The patient did not react to cooked garlic, and skin prick tests showed allergy only to raw garlic (96015). Researchers note that at least some allergens in raw garlic are heat labile (88392,96012,96015). This suggests that consuming cooked rather than raw garlic may help avoid this reaction in patients allergic to raw garlic. However, different people react to different allergens in garlic. At least some of these allergens are heat stable (96012). While rare, garlic-induced anaphylaxis has been reported (88392,96012).
Topically, allergic contact dermatitis has been reported in case reports (51406,51498,51510,51519,51560).
Musculoskeletal ...Orally, garlic has been associated with individual cases of gout and low back pain (51474,51467), but it is not clear if these adverse events can be attributed to garlic.
Neurologic/CNS ...Orally, dizziness, insomnia, headaches, diaphoresis, fever, chills, somnolence, increased appetite, euphoria, and weight loss have been reported with garlic (15032,42692,51316,51467,51471,51520). In one case, the smell of garlic was identified as a trigger for migraines in a 32-year-old female. The subject reported fortification spectra along with visual spots for a few seconds followed by instantaneous biparietal, crushing level (10/10) headaches upon exposure to the scent of garlic or onion (88404).
Pulmonary/Respiratory ...Garlic exposure, most notably in occupational settings, may cause asthma and other symptoms such as sneezing, nasal obstruction, rhinorrhea, and sinusitis (40661,51218). A case of minor hemoptysis has been reported for one patient with cystic fibrosis following intake of garlic capsules orally once daily for 8 weeks (51438). A 77-year-old female developed pneumonia related to the intake of one whole black garlic clove daily. The cloves were prepared by heating a whole garlic bulb in a pot for one month. Symptoms included dyspnea and coughing, and test results were positive for lymphocyte-induced stimulation by black garlic and raw garlic. The patient required treatment with oral steroids and was told to avoid garlic (96011).
General
...Orally, guggul seems to be generally well tolerated.
Most Common Adverse Effects:
Orally: Belching, bloating, diarrhea, headache, nausea, unpleasant taste, and vomiting. Allergic and non-allergic skin reactions.
Topically: Allergic contact dermatitis in sensitive individuals.
Serious Adverse Effects (Rare):
Orally: Rhabdomyolysis.
Dermatologic
...Orally, guggul can cause hypersensitivity reactions including rash and pruritus (10371,54457).
Guggul can also cause nonallergic adverse skin reactions. The risk of skin reactions appears to be dose-dependent. In one study, the incidence of skin reactions was 3% with a dosage of 1000 mg three times daily, compared with 15% with a dosage of 2000 mg three times daily. The severity of the reactions ranged from pruritus to swelling and erythema of the face to bullous lesion on the lower legs associated with headaches, myalgias, and pruritus (13662).
Topically, guggul can cause allergic contact dermatitis (54464,54467). Also, in a small clinical study, one patient using a cream containing aqueous extracts of guggul and Allium ampeloprasum as well as sesame oil complained of rash at the application site (105751). It is unclear if this reaction was due to guggul, other ingredients, or other factors.
Gastrointestinal ...Orally, guggul can cause nausea, vomiting, loose stools, diarrhea, belching, bloating, hiccups, and mild gastrointestinal discomfort (3267,8155,8158,10371,52033,54492).
Hepatic ...A case of severe hypertransaminasemia has been reported for a 63-year-old female who took a specific product (Equisterol) containing guggulsterone and red yeast rice extract daily for 6 months. Liver function normalized after discontinuing the supplement. It is unclear if the adverse effect was due to guggulsterone, red yeast, or the combination. However, the patient had previously developed hepatotoxicity while taking lovastatin, and red yeast contains monacolin K, which is identical to lovastatin (54477). Also, a case of acute liver failure requiring liver transplantation has been reported for a previously healthy young female who used a mixed-ingredient dietary supplement containing extracts of green tea, guggul, and usnic acid. It is unclear if the hepatotoxicity was due to guggul or other ingredients; green tea has been associated with hepatotoxicity (54027).
Immunologic
...Orally, guggul can cause hypersensitivity reactions including rash and pruritus (10371,54457).
In a small clinical study, two adults with hyperlipidemia developed a hypersensitivity rash, one with facial edema, within minutes of oral administration of a methanolic extract of guggul, together with Terminalia extract (105741). It is unclear if this reaction was due to guggul, Terminalia, or other factors.
Topically, guggul can cause allergic contact dermatitis (54464,54467).
Musculoskeletal ...There is one case of rhabdomyolysis reported in a patient who took guggul 300 mg three times daily. The patient developed hemoglobinuria within 2 weeks of starting guggul in addition to increased alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase, creatine kinase, and myoglobinemia. The patient did not have any muscular symptoms. The patient's condition improved when guggul was discontinued. The patient had a history of developing elevated creatine kinase levels after taking simvastatin; however, the patient was not taking a statin at the time of this episode of rhabdomyolysis (13029).
Neurologic/CNS ...Orally, guggul can cause headaches (3267,8155,8158,10371,42692,49583). Less commonly, guggul may cause restlessness and apprehension (49583,54492).
General
...No adverse effects have been reported in adults.
However, a thorough evaluation of safety outcomes has not been conducted.
Serious Adverse Effects (Rare):
Orally: Gastrointestinal adverse effects, such as necrotizing enterocolitis, when recombinant human bile salt-stimulated lipase is used in premature infants.
Gastrointestinal ...Orally, when added to the formula or pasteurized breast milk consumed by premature infants, recombinant human bile salt-stimulated lipase (rhBSSL) can cause gastrointestinal adverse effects, including abdominal distension, flatulence, constipation, colic, abdominal pain, gastroenteritis, vomiting, regurgitation, and rectal bleeding (101940). Premature infants receiving rhBSSL also had a slightly higher rate of necrotizing enterocolitis (NEC) when compared with those receiving placebo. After review by a panel of experts, it was determined that the rate of confirmed or suspected NEC in infants consuming rhBSSL was 3.3%, compared with 0.5% in those receiving placebo. Although this rate of NEC is lower than the historical rate of occurrence in premature infants (11%), a possible increased risk for NEC cannot be ruled out (101940).
