Cyclosome Delivery™ For Enhanced Bioavailability200 mg Per Tablet95% OPC European SourcedCirculatory & Blood Sugar SupportSourced From a GMP Certified Facility - Quality Assured Non-GMODietary Supplement Grape seeds have been used traditionally for thousands of years in Europe and studied for their powerful antioxidant benefits, including phenolic acids, anthocyanins, flavonoids and oligomeric proanthocyanidins (OPC's) or plant metabolites. Hi-Tech Pharmaceuticals uses the highest quality full-spectrum European grape seed extract with 95% OPC's including additional healthy plant metabolites for a more synergistic formula. Hi-Tech's Grape Seed Extract naturally contains polyphenols known as oligomeric proanthocyanidins (OPCs). In addition to being cardio protective, proanthocyanidin compounds possess the powerful antioxidant properties that help fight cell-damaging free radicals which can cause oxidative stress in the body, and in turn contribute to premature aging of cells. Our Grape Seed extract is carefully tested and produced to certified quality standards. It has also been shown to protect & strengthen collagen, a key component for healthy skin, connective tissue and vascular walls. Our scientifically advanced Cyclosome™ technology sets our ingredients apart using natural liposomes to protect the grape seed extract through digestion and a starch cyclodextrin for optimal absorption.
