To get the amounts of resveratrol the researchers are talking about, you have to drink massive amounts of wine (hundreds of bottles of wine) and/or tons of peanuts. You obviously cannot do this (at least in a healthy manner), which is why using a high quality supplement is most beneficial. I recommend a drinkable form of resveratrol made by NutraMetrix Advanced Nutraceuticals. Click here to learn more about the benefits and uniqueness of this resveratrol supplement.
