Description: Curcumin is a diarylheptanoid. It is the principal curcuminoid of turmeric, which is a member of the ginger family (Zingiberaceae). Turmeric's other two curcuminoids are desmethoxycurcumin and bis-desmethoxycurcumin. Curcumin is a bright-yellow color and may be used as a food coloring. As a food additive, its E number is E100. A survey of the literature shows a number of potential effects under study and that daily doses over a 3-month period of up to 12 grams were safe. Clinical trials in humans are studying the effect of curcumin on various diseases, including multiple myeloma, pancreatic cancer, myelodysplastic syndromes, colon cancer, psoriasis, arthritis, major depressive disorder and Alzheimer's disease.

Additional Information

A 2014 review of human clinical trials found no benefit to 5-8 weeks of curcumin consumption compared to placebo or no treatment for patients with major depressive disorder. A number of trials studying curcumin efficacy and safety revealed poor absorption and low bioavailability. (Source:
