Curcumin is the active ingredient of the curry spice Turmeric, ground from the root of the plant called Curcuma Longa. Curcumin is believed to be one of nature’s most powerful antioxidants with many health benefits. HealthAid Curcumin contains the Active C3 form of Curcumin which is its purest form. Curcumin alone is poorly absorbed by the body, making bioavailability a major issue. Health Aid Curcumin (C3) supplement contains Bioperine which substantially increases the efficacy and absorption.
