Below is general information about the safety of the known ingredients contained in the product Curcumin Extreme. 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 food amounts (14145). There is insufficient reliable information available about the safety of broccoli when used in medicinal amounts.
PREGNANCY AND LACTATION: LIKELY SAFE
when used orally in food amounts (14145).
There is insufficient reliable information available about the safety of broccoli when used in medicinal amounts during pregnancy and lactation; avoid using.
LIKELY SAFE ...when used orally and appropriately. Selenium appears to be safe when taken short-term in amounts below the tolerable upper intake level (UL) of 400 mcg daily (4844,7830,7831,7836,7841,9724,9797,14447,17510,17511)(17512,17513,17515,17516,97087,97943,109085); however, there is concern that taking selenium long-term might not be safe. Some evidence shows that consuming a diet containing more than the recommended dietary allowance (RDA) of selenium, which is 55 mcg daily for most adults, is associated with an increased risk for developing type 2 diabetes (99661). Some evidence also shows that taking a selenium supplement 200 mcg daily for an average of 3-8 years increases the risk of developing type 2 diabetes (97091,99661). Higher serum levels of selenium are also associated with an increased risk of developing diabetes and increased mortality (16710,99661). ...when used intravenously. Selenium, as selenious acid, is an FDA-approved drug. Sodium selenite intravenous infusions up to 1000 mcg daily have been safely used for up to 28 days (90347,92910).
POSSIBLY UNSAFE ...when used orally in high doses or long-term. Doses above 400 mcg daily can increase the risk of developing selenium toxicity (4844,7825). Additionally, some evidence shows that consuming a diet containing more than the recommended dietary allowance (RDA) of selenium, which is 55 mcg daily for most adults, is associated with an increased risk for developing type 2 diabetes (99661). There is also concern that taking a selenium supplement 200 mcg daily long-term, for an average of 3-8 years, increases the risk of developing type 2 diabetes (99661). Higher serum levels of selenium are also associated with an increased risk of developing diabetes and increased mortality (16710,99661).
CHILDREN: POSSIBLY SAFE
when used orally and appropriately.
Selenium seems to be safe when used short-term in doses below the tolerable upper intake level (UL) of 45 mcg daily for infants up to age 6 months, 60 mcg daily for infants 7 to 12 months, 40-90 mcg daily for children 1 to 3 years, 100-150 mcg daily for children 4 to 8 years, 200-280 mcg daily for children 9 to 13 years, and 400 mcg daily for children age 14 years and older (4844,86095); however, there is some concern that long-term use might not be safe. ...when used via a nasogastric tube in premature infants (7835,9764).
PREGNANCY: POSSIBLY SAFE
when used orally and appropriately.
Selenium appears to be safe when used short-term in amounts that do not exceed the tolerable upper intake level (UL) of 400 mcg daily (4844,17507,74419,74481,74391); however, there is concern that long-term use might not be safe.
PREGNANCY: POSSIBLY UNSAFE
when used orally in excessive doses.
Doses above 400 mcg daily may cause significant toxicity (4844).
LACTATION: POSSIBLY SAFE
when used orally and appropriately.
Selenium appears to be safe when used short-term in amounts that do not exceed the tolerable upper intake level (UL) of 400 mcg daily when taken short-term (4844,74467); however, there is concern that long-term use might not be safe.
LACTATION: POSSIBLY UNSAFE
when used orally in excessive doses.
Doses above 400 mcg daily may cause significant toxicity (4844,7838). ...when used orally in HIV-positive women. Selenium supplementation in HIV-positive women not taking highly active antiretroviral therapy may increase HIV-1 levels in breast milk (90358).
LIKELY SAFE ...when used orally and appropriately, short-term. Turmeric products providing up to 8 grams of curcumin have been safely used for up to 2 months (10453,11144,11150,17953,79085,89720,89721,89724,89728,101347)(81036,101349,107110,107116,107117,107118,107121,109278,109283). Turmeric in doses up to 3 grams daily has been used with apparent safety for up to 3 months (102350,104146,104148). ...when used topically and appropriately (11148).
POSSIBLY SAFE ...when used as an enema, short-term. Turmeric extract in water has been used as a daily enema for up to 8 weeks (89729). ...when used topically as a mouthwash, short-term. A mouthwash containing 0.05% turmeric extract and 0.05% eugenol has been used safely twice daily for up to 21 days (89723).
PREGNANCY: LIKELY SAFE
when used orally in amounts commonly found in food.
PREGNANCY: LIKELY UNSAFE
when used orally in medicinal amounts; turmeric might stimulate the uterus and increase menstrual flow (12).

Theoretically, broccoli might reduce the levels and effects of drugs metabolized by CYP1A2.
 Details
|
Theoretically, broccoli might reduce the levels and effects of drugs metabolized by CYP2A6.
Details
Pharmacokinetic research in humans shows that eating 500 grams of broccoli daily for 6 days increases CYP2A6 activity by 135% to 550%. Induction of CYP2A6 activity is attributed to its glucosinolate constituents (19608).
|
Selenium may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs.
Details
Clinical research suggests that taking selenium 10 mcg/kg/day can increase bleeding times by increasing prostacyclin production, which inhibits platelet activity (14540). Other clinical research suggests that taking selenium 75 mcg daily, in combination with ascorbic acid 600 mg, alpha-tocopherol 300 mg, and beta-carotene 27 mg, reduces platelet aggregation (74406).
|
Theoretically, selenium might prolong the sedating effects of barbiturates.
Details
|
Contraceptive drugs might increase levels of selenium, although the clinical significance of this effect is unclear.
Details
Some research suggests that oral contraceptives increase serum selenium levels in women taking oral contraceptives; however, other research shows no change in selenium levels (14544,14545,14546,101343). It is suggested that an increase could be due to increased carrier proteins, indicating a redistribution of selenium rather than a change in total body selenium (14545).

Theoretically, selenium supplementation may reduce the effectiveness of immunosuppressant therapy.
Details

Selenium might reduce the beneficial effects of niacin on high-density lipoprotein (HDL) levels.
Details
A combination of niacin and simvastatin (Zocor) effectively raises HDL cholesterol levels in patients with coronary disease and low HDL levels. Clinical research shows that taking a combination of antioxidants (vitamin C, vitamin E, beta-carotene, and selenium) along with niacin and simvastatin (Zocor) attenuates this rise in HDL, specifically the HDL-2 and apolipoprotein A1 fractions, by more than 50% in patients with coronary disease (7388,11537). It is not known whether this adverse effect is due to a single antioxidant such as selenium, or to the combination. It also is not known whether it will occur in other patient populations.
|
Theoretically, selenium might interfere with warfarin activity.
Details
Animal research suggests that selenium can increase warfarin activity. Selenium might interact with warfarin by displacing it from albumin binding sites, reducing its metabolism in the liver, or by decreasing production of vitamin K-dependent clotting factors (14541). Selenium can also prolong bleeding times in humans by increasing prostacyclin production, which inhibits platelet activity (14540).
|
Turmeric has antioxidant effects. Theoretically, this may reduce the activity of chemotherapy drugs that generate free radicals. However, research is conflicting.
Details
In vitro research suggests that curcumin, a constituent of turmeric, inhibits mechlorethamine-induced apoptosis of breast cancer cells by up to 70%. Also, animal research shows that curcumin inhibits cyclophosphamide-induced tumor regression (96126). However, some in vitro research shows that curcumin does not affect the apoptosis capacity of etoposide. Also, other laboratory research suggests that curcumin might augment the cytotoxic effects of alkylating agents. Reasons for the discrepancies may relate to the dose of curcumin and the specific chemotherapeutic agent. Lower doses of curcumin might have antioxidant effects while higher doses might have pro-oxidant effects (96125). More evidence is needed to determine what effect, if any, turmeric might have on alkylating agents.
|
Taking turmeric with amlodipine may increase levels of amlodipine.
Details
Animal research shows that giving amlodipine 1 mg/kg as a single dose following the use of turmeric extract 200 mg/kg daily for 2 weeks increases the maximum concentration and area under the curve by 53% and 56%, respectively, when compared with amlodipine alone (107113). Additional animal research shows that taking amlodipine 1 mg/kg with a curcumin 2 mg/kg pretreatment for 10 days increases the maximum concentration and area under the curve by about 2-fold when compared with amlodipine alone (103099).
|
Turmeric may have antiplatelet effects and may increase the risk of bleeding if used with anticoagulant or antiplatelet drugs. However, research is conflicting.
Details
Curcumin, a constituent of turmeric, has demonstrated antiplatelet effects in vitro (11143,81204,81271). Furthermore, two case reports have found that taking turmeric along with warfarin or fluindione was associated with an increased international normalized ratio (INR) (89718,100906). However, one clinical study in healthy volunteers shows that taking curcumin 500 mg daily for 3 weeks, alone or with aspirin 100 mg, does not increase antiplatelet effects or bleeding risk (96137). It is possible that the dose of turmeric used in this study was too low to produce a notable effect.
|
Theoretically, taking turmeric with antidiabetes drugs might increase the risk of hypoglycemia.
Details
Animal research and case reports suggest that curcumin, a turmeric constituent, can reduce blood glucose levels in patients with diabetes (79692,79984,80155,80313,80315,80476,80553,81048,81219). Furthermore, clinical research in adults with type 2 diabetes shows that taking curcumin 475 mg daily for 10 days prior to taking glyburide 5 mg decreased postprandial glucose levels for up to 24 hours when compared with glyburide alone, despite the lack of a significant pharmacokinetic interaction (96133). Another clinical study in patients with diabetes on hemodialysis shows that taking curcumin 80 mg daily for 12 weeks can reduce blood glucose levels when compared with placebo (104149).
|
Turmeric has antioxidant effects. Theoretically, this may reduce the activity of chemotherapy drugs that generate free radicals. However, research is conflicting.
Details
In vitro and animal research shows that curcumin, a constituent of turmeric, inhibits doxorubicin-induced apoptosis of breast cancer cells by up to 65% (96126). However, curcumin does not seem to affect the apoptosis capacity of daunorubicin. In fact, some research shows that curcumin might augment the cytotoxic effects of antitumor antibiotics, increasing their effectiveness. Reasons for the discrepancies may relate to the dose of curcumin and the chemotherapeutic agent. Lower doses of curcumin might have antioxidant effects while higher doses might have pro-oxidant effects (96125). More evidence is needed to determine what effects, if any, antioxidants such as turmeric have on antitumor antibiotics.

Turmeric might increase levels of drugs metabolized by CYP3A4.
Details
In vitro and animal research show that turmeric and its constituents curcumin and curcuminoids inhibit CYP3A4 (21497,21498,21499). Also, 8 case reports from the World Health Organization (WHO) adverse drug reaction database describe increased toxicity in patients taking turmeric and cancer medications that are CYP3A4 substrates, including everolimus, ruxolitinib, ibrutinib, and palbociclib, and bortezomib (111644). In another case report, a transplant patient presented with acute nephrotoxicity and elevated tacrolimus levels after consuming turmeric powder at a dose of 15 or more spoonfuls daily for ten days prior. It was thought that turmeric increased levels of tacrolimus due to CYP3A4 inhibition (93544).
|
Theoretically, turmeric might increase blood levels of oral docetaxel.
Details
Animal research suggests that the turmeric constituent, curcumin, enhances the oral bioavailability of docetaxel (80999). However, the significance of this interaction is unclear, as this drug is typically administered intravenously in clinical settings.
|
Theoretically, large amounts of turmeric might interfere with hormone replacement therapy through competition for estrogen receptors.
Details
In vitro research shows that curcumin, a constituent of turmeric, displaces the binding of estrogen to its receptors (21486).
|
Theoretically, taking turmeric and glyburide in combination might increase the risk of hypoglycemia.
Details
Clinical research shows that taking curcumin 475 mg daily for 10 days prior to taking glyburide 5 mg increases blood levels of glyburide by 12% at 2 hours after the dose in patients with type 2 diabetes. While maximal blood concentrations of glyburide were not affected, turmeric modestly decreased postprandial glucose levels for up to 24 hours when compared to glyburide alone, possibly due to the hypoglycemic effect of turmeric demonstrated in animal research (96133).
|
Theoretically, turmeric might increase the risk of liver damage when taken with hepatotoxic drugs.
Details
|
Theoretically, turmeric might increase the effects of losartan.
Details
Research in hypertensive rats shows that taking turmeric can increase the hypotensive effects of losartan (110897).
|
Theoretically, turmeric might have additive effects when used with hepatotoxic drugs such as methotrexate.
Details
In one case report, a 39-year-old female taking methotrexate, turmeric, and linseed oil developed hepatotoxicity (111644).
|
Theoretically, turmeric might increase the effects and adverse effects of norfloxacin.
Details
Animal research shows that taking curcumin, a turmeric constituent, can increase blood levels of orally administered norfloxacin (80863).
|
Theoretically, turmeric might increase the absorption of P-glycoprotein substrates.
Details
|
Theoretically, turmeric might alter blood levels of paclitaxel, although any effect may not be clinically relevant.
Details
Clinical research in adults with breast cancer receiving intravenous paclitaxel suggests that taking turmeric may modestly alter paclitaxel pharmacokinetics. Patients received paclitaxel on day 1, followed by either no treatment or turmeric 2 grams daily from days 2-22. Pharmacokinetic modeling suggests that turmeric reduces the maximum concentration and area under the curve of paclitaxel by 12.1% and 7.7%, respectively. However, these changes are not likely to be considered clinically relevant (108876). Conversely, animal research suggests that curcumin, a constituent of turmeric, enhances the oral bioavailability of paclitaxel (22005). However, the significance of this interaction is unclear, as this drug is typically administered intravenously in clinical settings.
|
Turmeric might increase the effects and adverse effects of sulfasalazine.
Details
Clinical research shows that taking the turmeric constituent, curcumin, can increase blood levels of sulfasalazine by 3.2-fold (81131).
|
Turmeric might increase the effects and adverse effects of tacrolimus.
Details
In one case report, a transplant patient presented with acute nephrotoxicity and elevated tacrolimus levels of 29 ng/mL. The patient previously had tacrolimus levels within the therapeutic range at 9.7 ng/mL. Ten days prior to presenting at the emergency room the patient started consumption of turmeric powder at a dose of 15 or more spoonfuls daily. It was thought that turmeric increased levels of tacrolimus due to cytochrome P450 3A4 (CYP3A4) inhibition (93544). In vitro and animal research show that turmeric and its constituent curcumin inhibit CYP3A4 (21497,21498,21499).
|
Turmeric may reduce the absorption of talinolol in some situations.
Details
Clinical research shows that taking curcumin for 6 days decreases the bioavailability of talinolol when taken together on the seventh day (80079). The clinical significance of this effect is unclear.
|
Theoretically, turmeric might reduce the levels and clinical effects of tamoxifen.
Details
In a small clinical trial in patients with breast cancer taking tamoxifen 20-30 mg daily, adding curcumin 1200 mg plus piperine 10 mg three times daily reduces the 24-hour area under the curve of tamoxifen and the active metabolite endoxifen by 12.8% and 12.4%, respectively, as well as the maximum concentrations of tamoxifen, when compared with tamoxifen alone. However, in the absence of piperine, the area under the curve for endoxifen and the maximum concentration of tamoxifen were not significantly reduced. Effects were most pronounced in patients who were extensive cytochrome P450 (CYP) 2D6 metabolizers (107123).
|
Turmeric has antioxidant effects. There is some concern that this may reduce the activity of chemotherapy drugs that generate free radicals. However, research is conflicting.
Details
In vitro research shows that curcumin, a constituent of turmeric, inhibits camptothecin-induced apoptosis of breast cancer cells by up to 71% (96126). However, other in vitro research shows that curcumin augments the cytotoxic effects of camptothecin. Reasons for the discrepancies may relate to the dose of curcumin and the chemotherapeutic agents. Lower doses of curcumin might have antioxidant effects while higher doses might have pro-oxidant effects (96125). More evidence is needed to determine what effect, if any, turmeric might have.
|
Turmeric might increase the risk of bleeding with warfarin.
Details
One case of increased international normalized ratio (INR) has been reported for a patient taking warfarin who began taking turmeric. Prior to taking turmeric, the patient had stable INR measurements. Within a few weeks of starting turmeric supplementation, the patient's INR increased to 10 (100906). Additionally, curcumin, the active constituent in turmeric, has demonstrated antiplatelet effects in vitro (11143,81204,81271), which may produce additive effects when taken with warfarin.

Below is general information about the adverse effects of the known ingredients contained in the product Curcumin Extreme. 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 ...Broccoli is well tolerated when consumed as food. A thorough evaluation of safety outcomes when broccoli is taken as medicine has not been conducted.
Dermatologic ...Topically, allergic reactions to broccoli have caused contact dermatitis (14158).
Hepatic ...In one case report, a 56-year-old adult developed elevated transaminases, with alanine aminotransferase (ALT) 5. 8 times above normal, aspartate aminotransferase (AST) 2.4 times above normal, and gamma-glutamyl transpeptidase (GGT) 5.1 times above normal. This was thought to be related to the consumption of 800 mL of broccoli juice daily over a 4-week period. Values returned to normal 15 days after cessation of juice consumption (96191).
Immunologic ...Topically, allergic reactions to broccoli have caused contact dermatitis (14158).
General
...Orally, selenium is generally well-tolerated when used in doses that do not exceed the tolerable upper intake level (UL) of 400 mcg daily.
Intravenously, selenium is generally well-tolerated.
Most Common Adverse Effects:
Orally: Gastric discomfort, headache, and rash. Excessive amounts can cause alopecia, dermatitis, fatigue, nail changes, nausea and vomiting, and weight loss.
Serious Adverse Effects (Rare):
Orally: Excessive ingestion has led to cases of multi-organ failure and death.
Dermatologic ...Excess selenium can produce selenosis in humans, affecting liver, skin, nails, and hair (74304,74326,74397,74495,90360) as well as dermatitis (74304). Results from the Nutritional Prevention of Cancer Trial conducted among individuals at high risk of nonmelanoma skin cancer demonstrate that selenium supplementation is ineffective at preventing basal cell carcinoma and that it increases the risk of squamous cell carcinoma and total nonmelanoma skin cancer (10687). Mild skin rash has been reported in patients taking up to 200 mcg of selenium daily for up to 12 months (97943).
Endocrine
...Multiple clinical studies have found an association between increased intake of selenium, either in the diet or as a supplement, and the risk for type 2 diabetes (97091,99661).
One meta-analysis shows that a selenium plasma level of 90 mcg/L or 140 mcg/L is associated with a 50% or 260% increased risk for developing type 2 diabetes, respectively, when compared with plasma levels below 90 mcg/L. Additionally, consuming selenium in amounts exceeding the recommended dietary allowance (RDA) is associated with an increased risk of developing diabetes when compared with consuming less than the RDA daily. Also, taking selenium 200 mcg daily as a supplement is associated with an 11% increased risk for diabetes when compared with a placebo supplement (99661).
Hypothyroidism, secondary to iodine deficiency, has been reported as a result of selenium intravenous administration (14563,14565). One large human clinical trial suggested a possible increased risk of type 2 diabetes mellitus in the selenium group (16707).
Gastrointestinal ...In human research, nausea, vomiting, and liver dysfunction has been reported as a result of high selenium exposure (74439,74376). Mild gastric discomfort has been reported in patients taking up to 200 mcg of selenium daily for up to 12 months (97943).
Genitourinary ...The effect of selenium supplementation on semen parameters is unclear. In human research, selenium supplementation may reduce sperm motility (9729); however, follow-up research reported no effect on sperm motility or any other semen quality parameter (74441).
Neurologic/CNS ...Chronic exposure to organic and inorganic selenium may cause neurotoxicity, particularly motor neuron degeneration, leading to an increased risk of amyotrophic lateral sclerosis (ALS) (74304). Mild headache has been reported in patients taking up to 200 mcg of selenium daily for up to 12 months (97943).
General
...Orally and topically, turmeric is generally well tolerated.
Most Common Adverse Effects:
Orally: Constipation, dyspepsia, diarrhea, distension, gastroesophageal reflux, nausea, and vomiting.
Topically: Curcumin, a constituent of turmeric, can cause contact urticaria and pruritus.
Cardiovascular ...Orally, a higher dose of turmeric in combination with other ingredients has been linked to atrioventricular heart block in one case report. It is unclear if turmeric caused this adverse event or if other ingredients or a contaminant were the cause. The patient had taken a combination supplement containing turmeric 1500-2250 mg, black soybean 600-900 mg, mulberry leaves, garlic, and arrowroot each about 300-450 mg, twice daily for one month before experiencing atrioventricular heart block. Heart rhythm normalized three days after discontinuation of the product. Re-administration of the product resulted in the same adverse effect (17720).
Dermatologic ...Following occupational and/or topical exposure, turmeric or its constituents curcumin, tetrahydrocurcumin, or turmeric oil, can cause allergic contact dermatitis (11146,79270,79470,79934,81410,81195). Topically, curcumin can also cause rash or contact urticaria (79985,97432,112117). In one case, a 60-year-old female, with no prior reactivity to regular oral consumption of turmeric products, developed urticaria after topical application of turmeric massage oil (97432). A case of pruritus has been reported following topical application of curcumin ointment to the scalp for the treatment of melanoma (11148). Orally, curcumin may cause pruritus, but this appears to be relatively uncommon (81163,97427,104148). Pitting edema may also occur following oral intake of turmeric extract, but the frequency of this adverse event is less common with turmeric than with ibuprofen (89720). A combination of curcumin plus fluoxetine may cause photosensitivity (89728).
Gastrointestinal ...Orally, turmeric can cause gastrointestinal adverse effects (107110,107112,112118), including constipation (81149,81163,96135), flatulence and yellow, hard stools (81106,96135), nausea and vomiting (10453,17952,89720,89728,96127,96131,96135,97430,112117,112118), diarrhea or loose stool (10453,17952,18204,89720,96135,110223,112117,112118), dyspepsia (17952,89720,89721,96161,112118), gastritis (89728), distension and gastroesophageal reflux disease (18204,89720), abdominal fullness and pain (81036,89720,96161,97430), epigastric burning (81444), and tongue staining (89723).
Hepatic
...Orally, turmeric has been associated with liver damage, including non-infectious hepatitis, cholestasis, and hepatocellular liver injury.
There have been at least 70 reports of liver damage associated with taking turmeric supplements for at least 2 weeks and for up to 14 months. Most cases of liver damage resolved upon discontinuation of the turmeric supplement. Sometimes, turmeric was used concomitantly with other supplements and medications (99304,102346,103094,103631,103633,103634,107122,109288,110221). The Drug-Induced Liver Injury Network (DILIN) has identified 10 cases of liver injury which were considered to be either definitely, highly likely, or probably associated with turmeric; none of these cases were associated with the use of turmeric in combination with other potentially hepatotoxic supplements. Most patients (90%) presented with hepatocellular pattern of liver injury. The median age of these case reports was 56 years and 90% identified as White. In these case reports, the carrier frequency on HLAB*35:01 was 70%, which is higher than the carrier frequency found in the general population. Of the ten patients, 5 were hospitalized and 1 died from liver injury (109288).
It is not clear if concomitant use with other supplements or medications contributes to the risk for liver damage. Many case reports did not report turmeric formulation, dosing, or duration of use (99304,103094,103631,103634,109288). However, at least 10 cases involved high doses of curcumin (250-1812.5 mg daily) and the use of highly bioavailable formulations such as phytosomal curcumin and formulations containing piperine (102346,103633,107122,109288,110221).
Neurologic/CNS ...Orally, the turmeric constituent curcumin can cause vertigo, but this effect seems to be uncommon (81163).
Psychiatric ...Orally, the turmeric constituent curcumin or a combination of curcumin and fluoxetine can cause giddiness, although this event seems to be uncommon (81206,89728).
Other ...There is a single case report of death associated with intravenous use of turmeric. However, analysis of the treatment vial suggests that the vial contained only 0.023% of the amount of curcumin listed on the label. Also, the vial had been diluted in a solution of ungraded polyethylene glycol (PEG) 40 castor oil that was contaminated with 1.25% diethylene glycol. Therefore the cause of death is unknown but is unlikely to be related to the turmeric (96136).
