Resveratrol’s oral bioavailability is about 20%, while Pterostilbene’s is about 80%. It’s a wonder why Pterostilbene hasn’t overtaken resveratrol in popularity yet.
By the way, we offer Pterostilbene here.
Pterostilbene is a double-methylated version of resveratrol exhibiting a higher bioavailability as it is more easily transported into the cell and more resistant to degradation and elimination. In rats, pterostilbene’s oral availability is 67%-94%, and its half-life has been published to be between 78 minutes and 104 minutes
