New look. Same formulas.

You probably noticed our new website, new logo, and new product labels. While our looks may have changed, our commitment to science and quality products remains untouched. Every product is still manufactured with the highest quality and safety standards in the world and still contains the exact same formula as before.

Please note that during the transition you might receive products with the former label as well as the new label. In every case, however, all of our products, regardless of label, are shipped with the maximum shelf-life in mind.

Benefits
Circulation, Skin/Hair
The primary constituents of Thorne's grape seed extract are oligomeric proanthocyanidins (OPCs). OPCs have strong free-radical scavenging (antioxidant) ability, resulting in inhibition of oxidative damage and protection of blood vessels and other tissues.* OPCs have been shown to protect vascular endothelial cells from oxidative damage and appear to strengthen the resistance of cell membranes to injury and impairment.* OPCs also can bind copper and iron, thereby reducing their oxidative effects.* OPC-100 contains Leucoselect Phytosome®, which have demonstrated in studies to reduce the oxidation of LDL-cholesterol in heavy smokers, and decrease oxidative stress in diabetics and in healthy individuals after a fatty meal.*

Evidence suggests OPCs enhance the cross-linkage of collagen in skin and other connective tissues.* OPCs have also been shown to decrease capillary permeability, which can be manifest as decreased bruising.* For example, clinical studies demonstrate reduced swelling and improved resolution of sports injuries in athletes who were given OPCs prior to a sporting event.*

A clinical study of 10 healthy volunteers analyzing the effect of OPC supplementation on biomarkers of oxidative stress found significantly increased levels of the antioxidant alpha-tocopherol in red blood cell membranes.*

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.*
