CurcuWIN 500 contains turmeric (Curcuma longa) root extract, concentrated to a minimum of 20% curcuminoids. CurcuWIN has significantly higher absorption compared to other curcumin ingredients. In a well-controlled human clinical trial, the first curcumin study of its kind to compare commercial curcumin products, CurcuWIN increased relative absorption of total curcuminoids 46-times over standard curcumin.* CurcuWIN also has longer-lasting action with higher serum concentrations after 12 hours.* CurcuWIN curcumin uses a molecular dispersion process (Ultrasol technology) which converts oil soluble nutrients into water-dispersible ingredients to enhance bioavailability and retention.*
