Grape Seed Extract

Grape seed extracts are derivatives from whole grape seeds that have a concentration of vitamin E, flavonoids, linoleic acid, and OPCs.

Preliminary studies in humans and animals show grape seed extract may be useful to treat high blood pressure and high cholesterol. By limiting lipid oxidation, phenolics in grape seeds may reduce risk of heart disease, such as by inhibiting platelet aggregation and reducing inflammation. A polyphenol contained in grape seeds is resveratrol which may interfere with cancer cell growth and proliferation, as well as induce apoptosis, among a variety of potential preventive effects.

Currently, there are clinical trials underway to assess the effect of grape seed extracts on human breast cancer, blood estrogen levels in postmenopausal women, and coronary artery disease.

Of note to strength athletes, grape seed extract is also an aromatase inhibitor; it suppresses the conversion of testosterone to estradiol.
