"Is it risky to take resveratrol?"
Resveratrol is a natural product and even a too high dose will not have any toxic effects on your body.
However, there is a recommended dose of resveratrol:
Start with a lose dose and then increase it gradually:
Dosage of resveratrol (per day):
1. week: 100 mg
2. week: 500mg
4. week: 1000mg
7. week: 1500mg
10.+ week: 2000mg
As I said there are no side effects or even toxic effects if you your daily dose is too high. By increasing it gradually, you allow your body to get used to it slowly.
