What is in Natural Resveratrol Liquid Concentrate?

Is that a lot?
Every amount on this label with a position sits within the middle 80% of the products that list the same ingredient; 15 ingredients sit inside a blend, so their amounts cannot be compared.
The Tolerable Upper Intake Level is the most of a nutrient per day, from food, water and supplements together, that is likely to pose no risk for almost all adults (Institute of Medicine, 2011). It does not apply under medical supervision. This page compares labels; it is not medical advice.
