OPC 100
OPCs are bioflavonoids with a very positive effect on the blood vessels. These substances are found in roots, bark, leaves, fruits and seeds. Thorne OPC 100 is good to use for unsightly veins, for the protection of cholesterol, good circulation and for blood pressure.
Phosphatidylcholine complex Leucoselect®
OPC 100 from Thorne Research is a grape seed extract with a high concentration of OPCs in the form of a patented phosphatidylcholine complex, Leucoselect®. This natural phosphatidylcholine ensures that the OPC is absorbed much better by the body.
Scientific human trial Leucoselect®
In a randomized human trial, young healthy volunteers received 300 mg of Leucoselect phytosome daily or a placebo. Antioxidant activity was measured at multiple time-points during days one and five. Within 30 minutes after administration on day one, the antioxidant activity measured by "total radical-trapping antioxidant parameter" (TRAP) was significantly elevated compared to placebo.*
