"THERACURMIN can safely increase plasma curcumin levels in a dose dependent manner at least up to 210 mg without saturating the absorption system. To the best of our knowledge, THERACURMIN is the first nanoparticle formulation of curcumin which demonstrates improved bioavailability in human subjects. We believe this compound could be a promising tool when testing the potential anti-cancer effects of curcumin in clinical trials".
