Before you take resveratrol

Ask a physician before use if you take blood thinners or other medication, are pregnant or nursing, or have a medical condition. The label amount is about 300 mg of trans-resveratrol per capsule, and the directions are two capsules a day. If you are trying to conceive or going through fertility treatment such as IVF, talk to your fertility doctor first. One retrospective study of women in IVF found an association between 200 mg of resveratrol a day and fewer clinical pregnancies and more miscarriages. It shows an association, not cause and effect, but it is a reason to ask.

How to take it

Take one (1) capsule twice a day, 20–30 min before a meal, or as directed by your healthcare professional.

We are serious about dosing. Ask away.

How much resveratrol is in a capsule?

The panel says 600 mg of a root complex containing 50% trans-resveratrol, so about 300 mg of trans-resveratrol per capsule. That is our arithmetic from the label's 50%; the panel does not print a separate figure and we hold no lab report for it. The other half of the complex is not identified on the label.

Is this the same as 600 mg of resveratrol?

No. 600 mg is the weight of the whole complex. About half of that, roughly 300 mg, is trans-resveratrol according to the label.

How many servings are in a bottle?

The panel prints a serving of 1 capsule and 60 servings per container. The directions say one capsule twice a day, which makes a bottle 30 days. Both are on the label, and we show both rather than pick one.

How do I take it?

One capsule twice a day, 20–30 minutes before a meal, or as directed by your healthcare professional. That is 2 capsules a day, about 1,200 mg of complex.

Who should check with a doctor first?

Ask a physician before use if you are pregnant or nursing, under 18, take medication (especially blood thinners) or have a medical condition. Do not exceed the recommended dose.
