Additional Information

Pterostilbene is a naturally occurring polyphenol closely related to Resveratrol. It is, however, more readily absorbed and utilized by the body. Emerging research suggests that Pterostilbene may help to support healthy vascular function, maintain proper cell cycle regulation, and can promote a healthy response to normal cellular stress.
