Perfect ResGrape Max is an all natural blend of Trans-Resveratrol and whole food Muscadine grapes. Perfect ResGrape Max only uses the purest and most potent natural Trans-Resveratrol available, with no less than 99% pure Trans-Resveratrol. In addition to Resveratrol, Perfect ResGrapeMax provides all the health benefits of whole food Organic Muscadine Grapes, known to have one of the highest antioxidant levels available. Now you can get the benefits of red wine - promote longevity & feel healthier - without the alcohol, calories, or preservatives! Perfect ResGrape Max may be the answer to becoming the healthiest YOU that you can be! Perfect Supplements believes you deserve to know exactly what is inside your dietary supplements. You will not find any "proprietary blends" here, just the facts. We only use 99% pure trans-resveratrol along with whole food Organic Muscadine grape, in which the skin, pulp and seed are dried and then ground into a powder. The powder is then contained in a vegetable capsule. Many other companies do not provide the health benefits of the whole grape, and use a cheap, low quality Resveratrol that has a purity of less than 50%. One of the impurities often found in low quality resveratrol is Emodin, which is used as a laxative and may cause stomach cramps.
