Curcuminoids are polyphenolic pigments found in the spice turmeric, derived from the roots of the tropical plant Curcuma longa. The major curcuminoids are curcumin, demethoxycurcumin and bisdemethoxycurcumin. Each demonstrates antioxidant activity. Consumption of curcuminoids is believed to result in a number of benefits to human health 1. The disposition of curcuminoids in the human body following oral ingestion is not well understood. Animal studies indicate that it is poorly absorbed; absorption appears to be improved when it is taken with food. Due to its questionable absorption, curcuminoid supplements are often formulated with bromelain to enhance its absorption 2.
