In a double-blind study of patients suffering from depression, the combination of antidepressant medication and curcuminoids (substances present in turmeric) given for 6 weeks improved depression to a significantly greater extent than antidepressant medication alone.
The product used in the study provided daily 1,000 mg of curcuminoids plus 10 mg of piperine (a substance in black pepper that is thought to increase the absorption of curcuminoids.)
In another study, supplementation with 1,000 mg per day of curcumin (one of the substances present in turmeric) for 8 weeks significantly improved depression, compared with a placebo, in patients suffering from depression. In that study, about one-third of the participants were taking an antidepressant medication. In another double-blind study, supplementation with 1,000 mg per day of curcumin enhanced the beneficial effect of antidepressant medication.
