Grape skin provides red wine with its colour, and it also contains a very high concentration of polyphenols, which are potent antioxidants. Red Grape Skin extract contains a mix of these substances, including nonbioflavonoid polyphenols (derivatives of cinnamic and benzoic acid) and bioflavonoid polyphenols (quercetin, catechins, flavonols, and anthocyanidins).
Researchers have found that one polyphenol in red wine – called Resveratrol – was found to have antiplatelet aggregating activity. Resveratrol is highly concentrated in the skin of grapes, and is abundant in red wine. It protects grapes and some other plants from fungal infections, and has been shown to have a number of beneficial medicinal properties including anticoagulant and anti-inflammatory effects.
Resveratrol, being a polyphenol, is a natural antioxidant that protects cells in the body against dangerous, naturally occurring substances known as free radicals. Oxidised cholesterol in the blood is deposited in the arteries and can cause blockages. Consuming antioxidants can also help prevent this process.
Resveratrol has a molecular structure similar to that of diethylstilbestrol, a synthetic estrogen - specifically, it is a phytoestrogen, a name derived from the Greek word for ‘plant’. Estrogen is known to provide some protection against heart disease. Their specific effects are similar, both increasing high-density lipoprotein (HDL), the ‘good cholesterol’. Supplementation may help with the following conditions: Aging, Atherosclerosis (heart disease), Capillary Fragility (bruising), Diabetes Inflammation, Macular Degeneration, Raynaud's Disease and Varicose Veins.
