Antioxidants inhibit oxidation (usually as autoxidation), a chemical reaction that can produce damaging free radicals. Oxidation can lead to polymerization and other chain reactions.
In cells, antioxidants such as curcumin, glutathione, mycothiol, or bacillithiol, and enzyme systems like superoxide dismutase, can prevent damage from oxidative stress.
Curcumin is a bright yellow chemical produced by plants of the Curcuma longa species. It is the principal curcuminoid of turmeric, a member of the ginger family, Zingiberaceae. It is obtained as a herbal supplement, cosmetics ingredient, food flavoring, and food coloring. However, in supplementation, seek out ultra-clean turmeric for maximum benefit.
Because turmeric is highly efficient at absorbing toxic heavy metals from the soil, and it's not easy to find ultra-clean turmeric from a reliable source. However, after searching all across the globe for the cleanest turmeric roots on the market and extensive lab-testing of its raw materials, ultra-clean organic turmeric root powder is available via this website that has passed stringent standards of cleanliness and purity.
