Yes grape seed extract does contain resveratrol but the amount may surprise you. If you have never heard of grape seed extract it is an extract that comes from grapes that many of the times was used in the wine industry. Not every single piece of grape gets used in wine so the companies take over the leftovers and use it to make grape seed.
Resveratrol is an ingredient that is found in plants and its main job in the jungle world is to protect plants from various harmful funguses and bacteria. When a person eats resveratrol they get some of these qualities as well. This substance got somewhat famous after medical scientist tested resveratrol on various animals and they discovered that it could extend life. Fruit flies, worms, mice, fish and yeast were all tested and this nutrient could extend these organisms life by as high as 70%. So naturally many people think that this this substance can do the same thing for humans.
Unfortunately it has not been tested yet. Now this doesn’t mean that resveratrol can’t extend the life of people it’s just not concrete. One of the ways that this nutrient can enable an animal to live longer is because it turns on a gene called SIRT1 which cuts calories from a person. The theory is that if a person eats less food they will generate less damage to their body which will enable them to live longer.
This is just one way that resveratrol can be beneficial to a person and there are tons of other different benefits that it can give someone as well. Someone can get this nutrient through red wine, grapes, chocolate, blueberries, strawberries, cranberries and mulberries. Out of all these choices red wine has the most with as high as 6 mg/L followed by the other berries while peanuts and chocolate have the least. However grape seed extract still has much more resveratrol than all of these choices, exactly how much really depends on the brand.
