Pure Encapsulations CurcumaSorb - 90 Capsules | Pure Encapsulations CurcumaSorb provides the Meriva® curcumin-phosphatidylcholine complex for enhanced absorption and bioavailability. The proprietary ‘phytosome’ complex promotes resistance to digestive degradation and efficient absorption across membranes. This produces significantly higher peak plasma concentrations and larger area under concentration-time curves (AUC). A human pharmacokinetic study demonstrated that elevations in plasma curcumin from 450 mg Meriva® were similar to values obtained from 4,000 mg of a standard curcumin extract.
