What's Grape Stem Extract
Grapes have been heralded for their medicinal and nutritional value for thousands of years. Grape stem extract is extracted from the stems of Vitis vinifera which contains natural resveratrol. It also provides cardiovascular protection by preventing oxidation of lipoproteins.
Resveratrol is a naturally occurring phytoalexin produced by some higher plants in response to injury or fungal infection. Phytoalexins are chemical substances produced by plants as a defense against infection by pathogenic microorganisms, such as fungi.
