This is the true sour Mediterranean grape powder, full-spectrum. Made from sun-dried, red, high-mountain immature grapes, it is more dense in grape active ingredients, such as ellagic acid and resveratrol than ripe grape extracts. This is why it’s ideal for supporting a healthy heart & circulatory response and also healthy detoxification. Plus, it’s filled with sour acids, like malic acid and tartaric acid, which support a healthy detox and kidney/bladder response.
