Below is general information about the safety of the known ingredients contained in the product Diet Partner Wellness Tea. 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 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.
LIKELY SAFE ...when used orally and appropriately, short-term. Eleuthero root extract 300-2000 mg has been used safely in clinical trials lasting up to 3 months (730,1427,2574,7522,11099,15586,91509). There is insufficient reliable information available about the safety of eleuthero when used long-term.
CHILDREN: POSSIBLY SAFE
when used orally in adolescents aged 12-17 years, short-term.
Eleuthero 750 mg three times daily was used for 6 weeks with apparent safety in one clinical trial (75028). There is insufficient reliable information available about the safety of eleuthero in children or adolescents when used long-term.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
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.
POSSIBLY SAFE ...when used orally and appropriately, short-term. Inositol has been used with apparent safety in doses up to 18 grams daily for up to 6 weeks or 6 grams daily for 10 weeks (2184,2185,2187,95089). Myo-inositol 4 grams daily has also been used with apparent safety for 6 months (95085). There is insufficient reliable information available about the safety of inositol when used topically.
CHILDREN: POSSIBLY SAFE
when used orally and appropriately.
Inositol 80 mg/kg (maximum 2 grams) has been taken daily for up to 12 weeks in children aged 5-12 years (95092). ...when used enterally or intravenously and appropriately in premature infants for treating acute respiratory distress syndrome for up to 10 days (2191,2192,91546,91551).
CHILDREN: POSSIBLY UNSAFE
when used enterally or intravenously for extended durations in premature infants.
A large clinical study in infants born at less than 28 weeks' gestation found that myo-inositol 40 mg/kg, given intravenously and then enterally every 12 hours for up to 10 weeks, was associated with a small increased risk of death (98946). Long-term follow-up until 24 months corrected age confirms that the initial increase in mortality rate in the myo-inositol group remained stable; however, there was no difference in a composite outcome of death or survival with moderate or severe neurodevelopmental impairment, as well as no difference in the risk of retinopathy of prematurity, between those who received myo-inositol or control (108819).
PREGNANCY: POSSIBLY SAFE
when used orally and appropriately, short-term.
Myo-inositol has been used with apparent safety in amounts up to 4000 mg daily during pregnancy (91548,95082,104688).
LACTATION:
Insufficient reliable information available; avoid using.
Breast milk is rich in endogenous inositol (2138); however, the effects of exogenously administered inositol are not known.
LIKELY SAFE ...when certain stevia constituents, including stevioside and rebaudiosides A, D, and M, are used orally as sweeteners in foods. These constituents have generally recognized as safe (GRAS) status in the US for this purpose (16699,16700,16702,16705,16706,108049). The stevia constituent stevioside has been safely used in doses of up to 1500 mg daily for 2 years (11809,11810,11811,113006). There is insufficient reliable information available about the safety of whole stevia or stevia extracts when used orally. The European Food Safety Authority (EFSA) has determined that the acceptable intake of steviol glycosides is 4 mg/kg daily (106456); however, it is unclear how this relates to the use of whole stevia or stevia extract.
PREGNANCY AND LACTATION:
Insufficient reliable information available; avoid using.
LIKELY SAFE ...when used orally, topically, intravenously, intramuscularly, or intranasally and appropriately. Vitamin B12 is generally considered safe, even in large doses (15,1344,1345,1346,1347,1348,2909,6243,7289,7881)(9414,9416,10126,14392,15765,82832,82949,82860,82864,90386)(111334,111551).
PREGNANCY: LIKELY SAFE
when used orally in amounts that do not exceed the recommended dietary allowance (RDA).
The RDA for vitamin B12 during pregnancy is 2.6 mcg daily (6243). There is insufficient reliable information available about the safety of larger amounts of vitamin B12 during pregnancy.
LACTATION: LIKELY SAFE
when used orally in amounts that do not exceed the recommended dietary allowance (RDA).
The RDA of vitamin B12 during lactation is 2.8 mcg daily (6243). There is insufficient reliable information available about the safety of larger amounts of vitamin B12 while breastfeeding.
LIKELY SAFE ...when used orally and appropriately in doses that do not exceed the tolerable upper intake level (UL) of 100 mg daily in the form of pyridoxine for adults (15,6243). ...when used parenterally and appropriately. Injectable vitamin B6 (pyridoxine) is an FDA-approved prescription product (15).
POSSIBLY SAFE ...when used orally and appropriately in doses of 101-200 mg daily (6243,8558).
POSSIBLY UNSAFE ...when used orally in doses at or above 500 mg daily. High doses, especially those exceeding 1000 mg daily or total doses of 1000 grams or more, pose the most risk. However, neuropathy can occur with lower daily or total doses (6243,8195). ...when used intramuscularly in high doses and frequency due to potential for rhabdomyolysis (90795).
CHILDREN: LIKELY SAFE
when used orally and appropriately in doses that do not exceed the tolerable upper intake level (UL) of vitamin B6 in the form of pyridoxine 30 mg daily for children aged 1-3 years, 40 mg daily for 4-8 years, 60 mg daily for 9-13 years, and 80 mg daily for 14-18 years (6243).
CHILDREN: POSSIBLY SAFE
when used orally and appropriately in amounts exceeding the recommended dietary allowance (5049,8579,107124,107125,107135).
CHILDREN: POSSIBLY UNSAFE
when used orally in excessive doses, long-term (6243).
PREGNANCY: LIKELY SAFE
when used orally and appropriately.
A special sustained-release product providing vitamin B6 (pyridoxine) 75 mg daily is FDA-approved for use in pregnancy. Vitamin B6 (pyridoxine) is also considered a first-line treatment for nausea and vomiting in pregnancy by the American College of Obstetrics and Gynecology (111601). However, it should not be used long-term or without medical supervision and close monitoring. The tolerable upper intake level (UL) refers to vitamin B6 in the form of pyridoxine and is 80 mg daily for those aged 14-18 years and 100 mg daily for 19 years and older (6243).
PREGNANCY: POSSIBLY UNSAFE
when used orally in excessive doses.
There is some concern that high-dose maternal vitamin B6 (pyridoxine) can cause neonatal seizures (4609,6397,8197).
LACTATION: LIKELY SAFE
when used orally in doses not exceeding the tolerable upper intake level (UL) of vitamin B6 in the form of pyridoxine 80 mg daily for those aged 14-18 years and 100 mg daily for those 19 years and older.
The recommended dietary allowance (RDA) in lactating women is 2 mg daily (6243). There is insufficient reliable information available about the safety of vitamin B6 when used in higher doses in breast-feeding women.

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, eleuthero may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Details
|
Theoretically, eleuthero might have additive effects when used with antidiabetes drugs.
Details
Animal research suggests that certain constituents of eleuthero have hypoglycemic activity in both healthy and diabetic animals (7591,73535,74932,74956,74988,74990). A small study in adults with type 2 diabetes also shows that taking eleuthero for 3 months can lower blood glucose levels (91509). However, one very small study in healthy individuals shows that taking powdered eleuthero 3 grams, 40 minutes prior to a 75-gram oral glucose tolerance test, significantly increases postprandial blood glucose levels when compared with placebo (12536). These contradictory findings might be due to patient-specific variability and variability in active ingredient ratios.
|
Theoretically, eleuthero might increase levels of drugs metabolized by CYP1A2.
Details
In vitro and animal research suggest that standardized extracts of eleuthero inhibit CYP1A2 (7532). This effect has not been reported in humans.
|
Theoretically, eleuthero might increase levels of drugs metabolized by CYP2C9.
Details
In vitro and animal research suggest that standardized extracts of eleuthero might inhibit CYP2C9 (7532). This effect has not been reported in humans.
|
Theoretically, eleuthero might increase levels of drugs metabolized by CYP2D6.
Details
|
Theoretically, eleuthero might increase levels of drugs metabolized by CYP3A4.
Details
|
Eleuthero might increase serum digoxin levels and increase the risk of side effects.
Details
In one case report, a 74-year-old male who was stabilized on digoxin presented with an elevated serum digoxin level after starting an eleuthero supplement, without symptoms of toxicity. After stopping the supplement, serum digoxin levels returned to normal (543). It is not clear whether this was due to a pharmacokinetic interaction or to interference with the digoxin assay (15585). Although the product was found to be free of digoxin and digitoxin (543), it was not tested for other contaminants (797).
|
Theoretically, eleuthero might interfere with immunosuppressive drugs because of its immunostimulant activity.
Details
|
Theoretically, eleuthero might decrease levels of drugs metabolized by OATP.
Details
In vitro research suggests that eleuthero inhibits OATP2B1, which might reduce the bioavailability of oral drugs that are substrates of OATP2B1 (35450). Due to the weak inhibitory effect identified in this study, this interaction is not likely to be clinically significant.
|
Theoretically, eleuthero might increase levels of P-glycoprotein substrates.
Details
|
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).
|
Theoretically, taking inositol with antidiabetes drugs might increase the risk of hypoglycemia.
Details
|
Theoretically, stevia might increase the risk for hypoglycemia when combined with antidiabetes drugs.
Details
Preliminary clinical research in patients with type 2 diabetes suggests that taking a single dose of stevia extract 1000 mg reduces postprandial blood glucose levels when taken with a meal (11812). However, other clinical research in patients with type 1 or type 2 diabetes suggests that taking stevioside 250 mg three times daily does not significantly affect blood glucose levels or glycated hemoglobin (HbA1C) after three months of treatment (16705).
|
Theoretically, combining stevia or stevia constituents with antihypertensive agents might increase the risk of hypotension.
Details
|
Theoretically, stevia might decrease clearance and increase levels of lithium.
Details
|
Theoretically, vitamin B6 might increase the photosensitivity caused by amiodarone.
Details
|
Theoretically, vitamin B6 may have additive effects when used with antihypertensive drugs.
Details
Research in hypertensive rats shows that vitamin B6 can decrease systolic blood pressure (30859,82959,83093). Similarly, clinical research in patients with hypertension shows that taking high doses of vitamin B6 may reduce systolic and diastolic blood pressure, possibly by reducing plasma levels of epinephrine and norepinephrine (83091).
|
Vitamin B6 may increase the metabolism of levodopa when taken alone, but not when taken in conjunction with carbidopa.
Details
Vitamin B6 (pyridoxine) enhances the metabolism of levodopa, reducing its clinical effects. However, this interaction does not occur when carbidopa is used concurrently with levodopa (Sinemet). Therefore, it is not likely to be a problem in most people (3046).
|
High doses of vitamin B6 may reduce the levels and clinical effects of phenobarbital.
Details
|
High doses of vitamin B6 may reduce the levels and clinical effects of phenytoin.

Below is general information about the adverse effects of the known ingredients contained in the product Diet Partner Wellness Tea. 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, 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, eleuthero root is generally well tolerated when used short-term.
Most Common Adverse Effects:
Orally: Diarrhea, dyspepsia, gastrointestinal upset, headache, nausea, and urticaria.
Cardiovascular ...Orally, increased blood pressure has been reported in children with hypotension taking eleuthero in one clinical study (74980). Eleuthero has been reported to cause tachycardia, hypertension, and pericardial pain in patients with rheumatic heart disease or atherosclerosis. It is unclear if these effects were caused by eleuthero, or by the cardioglycoside-containing herb, silk vine (Periploca sepium), which is a common adulterant found in eleuthero products (12,797,6500).
Dermatologic ...Orally, eleuthero has been reported to cause rash in some clinical studies (75013,75028).
Gastrointestinal ...Orally, eleuthero has been reported to cause dyspepsia, nausea, diarrhea, and gastrointestinal upset in some patients (74938,75028,91510).
Genitourinary ...Orally, mastalgia and uterine bleeding were reported in 7. 3% of females taking eleuthero 2 grams daily in one clinical study (6500,11099). These adverse effects seem to be more likely with higher doses.
Neurologic/CNS
...Orally, headaches have been reported in 9.
8% of people taking eleuthero in one clinical study (11099).
In one case report, a 53-year-old female developed spontaneous subarachnoid hemorrhage associated with the use of an herbal supplement containing red clover, dong quai, and eleuthero (70419). It is unclear if this event was related to the use of eleuthero, the other ingredients, the combination, or another cause entirely.
Psychiatric ...Orally, nervousness has been reported in 7. 3% of people taking eleuthero in one clinical study (11099). Eleuthero has also been reported to cause slight anxiety, irritability, and melancholy in some patients (6500,11099). These adverse effects seem to be more likely to occur with higher doses.
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 and intravenously, inositol seems to be well tolerated.
Topically, no adverse effects have been reported, although a thorough evaluation of safety outcomes has not been conducted.
Most Common Adverse Effects:
Orally: Diarrhea, gas, and nausea.
Gastrointestinal ...Orally, inositol may cause nausea, diarrhea, gas, and gastrointestinal discomfort (10387,11972,91547,91549,95089,95090,95092).
Immunologic ...Orally, inositol in combination with omega-3 fatty acids has been associated with reports of cold and allergy symptoms in children in clinical research (95092).
Musculoskeletal ...Orally, inositol in combination with omega-3 fatty acids has been associated with reports of tics and other musculoskeletal side effects in children in clinical research (95092).
Neurologic/CNS ...Orally, inositol may cause dizziness, tiredness, insomnia, agitation, and headache (10387,11972,95089,95092). In combination with omega-3 fatty acids, inositol has been associated with reports of feelings of thirst in children in clinical research (95092).
Psychiatric ...In one case report, a 36-year-old male with adequately controlled bipolar disorder was hospitalized with symptoms of mania after consuming several cans of an energy drink containing inositol, caffeine, taurine, and other ingredients (Red Bull Energy Drink) over a period of 4 days (14302). It is not known if this is related to inositol, caffeine, taurine, a different ingredient, or a combination of the ingredients.
General
...Orally, stevia and steviol glycosides appear to be well tolerated.
Most minor adverse effects seem to resolve after the first week of use.
Most Common Adverse Effects:
Abdominal bloating, dizziness, headache, myalgia, nausea, and numbness.
Serious Adverse Effects (Rare):
Allergic reactions.
Gastrointestinal ...Orally, stevia and steviol glycosides such as stevioside, can cause gastrointestinal adverse effects such as abdominal fullness and nausea. However, these generally resolve after the first week of use (11809,11810,113005).
Immunologic ...Theoretically, stevia might cause allergic reactions in individuals sensitive to plants in the Asteraceae/Compositae family (11811). Members of this family include ragweed, chrysanthemums, marigolds, daisies, and many other herbs.
Musculoskeletal ...Orally, stevia and steviol glycosides may cause myalgia, but this generally resolves after the first week of use (11809,11810).
Neurologic/CNS ...Orally, stevia and steviol glycosides may cause headache, dizziness, and numbness (11809,11810).
General
...Orally, intramuscularly, and topically, vitamin B12 is generally well-tolerated.
Most Common Adverse Effects:
Intramuscular: Injection site reactions.
Serious Adverse Effects (Rare):
Intramuscularly: Severe hypokalemia has been rarely linked with correction of megaloblastic anemia with vitamin B12.
Cardiovascular ...In human clinical research, an intravenous loading dose of folic acid, vitamin B6, and vitamin B12, followed by daily oral administration after coronary stenting, increased restenosis rates (12150). Hypertension following intravenous administration of hydroxocobalamin has been reported in human research (82870,82864).
Dermatologic
...Orally or intramuscularly, vitamin B12 can cause allergic reactions such as rash, pruritus, erythema, and urticaria.
Theoretically, allergic reactions might be caused by the cobalt within the vitamin B12 molecule (82864,90373,90381,103974). In one case report, oral methylcobalamin resulted in contact dermatitis in a 59-year-old Japanese female with a cobalt allergy (103974). In another case report, a 69-year-old female developed a symmetrical erythematous-squamous rash for 5 years after oral vitamin B12 supplementation for 10 years. A patch test confirmed that the systemic allergic dermatitis was due to vitamin B12 supplementation, which resolved 3 months after discontinuation (114578).
Vitamin B12 (intramuscular or oral) has also been associated with at least 19 cases of acneiform eruptions which resolved upon discontinuation of vitamin B12 (90365,90369,90388). High-dose vitamin B12 (20 mcg daily) and vitamin B6 (80 mg daily) have been associated with cases of rosacea fulminans characterized by intense erythema with nodules, papules, and pustules. Symptoms may last up to four months after the supplement is stopped and can be treated with systemic corticosteroids and topical therapy (10998,82870,82871).
Gastrointestinal ...Intravenously, vitamin B12 (hydroxocobalamin) 2. 5-10 grams can cause nausea and dysphagia (82864).
Genitourinary ...Intravenously, vitamin B12 (hydroxocobalamin) 5-15 grams has been associated with chromaturia in clinical research (82870,82871,112282,112264).
Hematologic ...According to case report data, the correction of megaloblastic anemia with vitamin B12 may result in fatal hypokalemia (82914).
Musculoskeletal ...According to case report data, correction of megaloblastic anemia with vitamin B12 has precipitated gout in susceptible individuals (82879).
Neurologic/CNS ...Treatment with vitamin B12 has been rarely associated with involuntary movements in infants with vitamin B12 deficiency (90370,90385,90397). In some cases these adverse reactions were misdiagnosed as seizures or infantile tremor syndrome (90370,90385). These adverse reactions presented 2-5 days after treatment with vitamin B12 and resolved once vitamin B12 was discontinued (90370,90385,90397).
Oncologic ...Although some epidemiological research disagrees (9454), most research has found that elevated plasma levels of vitamin B12 are associated with an increased risk of various types of cancer, including lung and prostate cancers and solid tumors (50411,102383,107743). One study found, when compared with blood levels of vitamin B12 less than 1000 ng/mL, plasma vitamin B12 levels of at least 1000 ng/mL was strongly associated with the occurrence of solid cancer (107743). It is unclear if increased intake of vitamin B12, either through the diet or supplementation, directly affects the risk of cancer. It is possible that having cancer increases the risk of vitamin B12 elevation. However, one observational study has found that the highest quintile of dietary intake of vitamin B12 is associated with a 75% increased incidence of developing esophageal cancer when compared with the lowest quintile in never drinkers, but not drinkers (107147).
Renal ...There is a case report of oxalate nephropathy in a 54-year-old male which was determined to be related to the use of intravenous hydroxocobalamin as treatment for cyanide poisoning. Intermittent hemodialysis was started 5 days after admission, along with a low-oxalate diet, oral calcium acetate, and pyridoxine 5 mg/kg daily (107148). A review of the use of intravenous hydroxocobalamin for suspected cyanide poisoning in 21 intensive care units in France between 2011 and 2017 resulted in a 60% increased odds of acute kidney injury and a 77% increased odds of severe acute kidney injury in the first week. However, biopsies were not conducted and a direct link with use of hydroxocobalamin could not be made (107139).
Other ...Several studies have found that higher vitamin B12 levels may be associated with increased mortality or decreased survival rates in hospitalized elderly patients (82889,82812,82857,82895). Human research has also found a positive correlation between vitamin B12 status and all-cause mortality in Pima Indians with diabetes (82863).
General
...Orally or by injection, vitamin B6 is well tolerated in doses less than 100 mg daily.
Most Common Adverse Effects:
Orally or by injection: Abdominal pain, allergic reactions, headache, heartburn, loss of appetite, nausea, somnolence, vomiting.
Serious Adverse Effects (Rare):
Orally or by injection: Sensory neuropathy (high doses).
Dermatologic ...Orally, vitamin B6 (pyridoxine) has been linked to reports of skin and other allergic reactions and photosensitivity (8195,9479,90375). High-dose vitamin B6 (80 mg daily as pyridoxine) and vitamin B12 (20 mcg daily) have been associated with cases of rosacea fulminans characterized by intense erythema with nodules, papules, and pustules. Symptoms may persist for up to 4 months after the supplement is stopped, and may require treatment with systemic corticosteroids and topical therapy (10998).
Gastrointestinal ...Orally or by injection, vitamin B6 (pyridoxine) can cause nausea, vomiting, heartburn, abdominal pain, mild diarrhea, and loss of appetite (8195,9479,16306,83064,83103,107124,107127,107135). In a clinical trial, one patient experienced infectious gastroenteritis that was deemed possibly related to taking vitamin B6 (pyridoxine) orally up to 20 mg/kg daily (90796). One small case-control study has raised concern that long-term dietary vitamin B6 intake in amounts ranging from 3.56-6.59 mg daily can increase the risk of ulcerative colitis (3350).
Hematologic ...Orally or by injection, vitamin B6 (pyridoxine) can cause decreased serum folic acid concentrations (8195,9479). One case of persistent bleeding of unknown origin has been reported in a clinical trial for a patient who used vitamin B6 (pyridoxine) 100 mg twice daily on days 16 to 35 of the menstrual cycle (83103). It is unclear if this effect was due to vitamin B6 intake.
Musculoskeletal ...Orally or by injection, vitamin B6 (pyridoxine) can cause breast soreness or enlargement (8195).
Neurologic/CNS ...Orally or by injection, vitamin B6 (pyridoxine) can cause headache, paresthesia, and somnolence (8195,9479,16306). Vitamin B6 (pyridoxine) can also cause sensory neuropathy, which is related to daily dose and duration of intake. Doses exceeding 1000 mg daily or total doses of 1000 grams or more pose the most risk, although neuropathy can occur with lower daily or total doses as well (8195). The mechanism of the neurotoxicity is unknown, but is thought to occur when the liver's capacity to phosphorylate pyridoxine via the active coenzyme pyridoxal phosphate is exceeded (8204). Some researchers recommend taking vitamin B6 as pyridoxal phosphate to avoid pyridoxine neuropathy, but its safety is unknown (8204). Vitamin B6 (pyridoxine) neuropathy is characterized by numbness and impairment of the sense of position and vibration of the distal limbs, and a gradual progressive sensory ataxia (8196,10439). The syndrome is usually reversible with discontinuation of pyridoxine at the first appearance of neurologic symptoms. Residual symptoms have been reported in patients taking more than 2 grams daily for extended periods (8195,8196). Daily doses of 100 mg or less are unlikely to cause these problems (3094).
Oncologic ...In females, population research has found that a median intake of vitamin B6 1. 63 mg daily is associated with a 3.6-fold increased risk of rectal cancer when compared with a median intake of 1.05 mg daily (83024). A post-hoc subgroup analysis of results from clinical research in adults with a history of recent stroke or ischemic attack suggests that taking folic acid, vitamin B12, and vitamin B6 does not increase cancer risk overall, although it was associated with an increased risk of cancer in patients who also had diabetes (90378). Also, in patients with nasopharyngeal carcinoma, population research has found that consuming at least 8.6 mg daily of supplemental vitamin B6 during treatment was associated with a lower overall survival rate over 5 years, as well as a reduced progression-free survival, when compared with non-users and those with intakes of up to 8.6 mg daily (107134).
