Resveratrol is a naturally occurring phytochemical classified as a polyphenol. It is present in over 70 species of plants, including Polygonum cuspidatum, grapes, and other herbs. Resveratrol exists in two forms, cis- and trans-. Although both compounds often exist in combination, the trans- form is more biologically active, and is the one most cited in the literature. All ENI resveratrol ingredients are standardized for the trans- form.

Our proprietary ResveraTrue™ product offers some unique and standout advantages in the field of resveratrol choices:
