What is the proper resveratrol dosage for your body? How much do you need and how often should you be taking it? These are the questions we'll answer here.
First of all resveratrol is not a drug. And since it is not a drug, the term "dosage" is really the wrong question. To ask that question would be similar to me asking you what dosage of apples I need. Without some sort of context or end goal, it's hard to even answer the question.
You've actually been consuming a good resveratrol dosage your entire life. Peanut butter and grape jelly sandwiches, mixed nuts, red wine, grape juice, Thanksgiving cranberries, dark chocolate. . . it's not something your body has to get used to.
So then the question is what are you trying to accomplish? If you're trying to stop free radicals from causing damage in your body, then the dosage question has some merit. Since free radicals are present all the time, every day - you really need to make sure you consume antioxidants (not necessarily resveratrol) every single day. And then depending on what is coupled with the resveratrol, you'd be well off to consume it during every meal.
When I say "coupled" with, I mean if you're going to get your resveratrol by eating PB&J sandwiches, then you don't want to overeat on Peanut Butter and Jelly just to get resveratrol. If it comes in a nutritional supplement that has 100% of you daily quota of copper, you don't want to overdo the copper just to get more resveratrol.
How much do you need in order to attain those secrets of longevity they talk about? No one actually knows. But I'd encourage you to keep track and when you're older than the oldest living person in your lineage - you'll know you took enough.
