It doesn't necessarily increase lifespan. It promotes cardiovascular and neurological health, healthy cholesterol and healthy blood pressureA substance called Resveratrol, found in the skin and seeds of red grapes as well as in wine, berries and some plants, is produced by plants in response to injury or fungal infection. It's believed to protect their delicate tissues from peroxidative stress and other damage that might result from illness, UV sun radiation or exposure to toxic substances.Resveratrol is also believed to provide similar protective benefits for humans. Its antioxidant activity, or ability to neutralize free radicals (unstable molecules that attack healthy cells and damage membranes and DNA), may account for its beneficial effects. Resveratrol also appears to promote healthy blood composition and circulation, and may also have anti-inflammatory properties.If you like red wine, a glass a day is good for you. Or you can take resveratrol, which comes in supplement form (minus the alcohol), and get the benefits.
