Dietary Supplements and Bioavailability: Suppliers Improve Ingredient Bioavailability

Bioavailability is especially important for curcumin, which is notoriously difficult for the body to absorb. Standard curcumin is unstable at intestinal pH levels, resulting in rapid degradation. In addition, studies have shown that regular curcumin has a poor pharmacokinetic profile for oral absorption, a high rate of metabolic conjugation and reduction, as well as a tendency to be rapidly eliminated from the body, says Indena S.p.A. (Milan, Italy).
