COMMON SOURCES: blueberries, almonds, grape leaves


PLANT COMPOUND TYPE: stilbenoid / polyphenol


DESCRIPTION: Pterostilbene is an antioxidant that's supposed to be really good for you, especially when used with Nicotinamide Riboside, but who cares about all that. Just remember that the P is silent! But seriously, pterostilbene is very similar to resveratrol, but it has much greater bioavailability, which basically means that the body can more readily absorb and use it.

Elysium: What Is Pterostilbene?

  • Pterostilbene is a polyphenol, a type of molecule that occurs in plants, particularly small berries and nuts.
  • Pterostilbenes connection to sirtuins is just one of the reasons scientists are so excited by the compound.
  • Pterostilbene and resveratrol have very similar chemical structures. However, there are differences and pterostilbene's structure makes it more bioavailable than resveratrol.

WikiPedia Entry For Pterostilbene

A randomized, double-blind, placebo-controlled of healthy human subjects given pterostilbene for 6-8 weeks, showed pterostilbene to be safe for human use at dosages up to 250 mg per day. Pterostilbene differs from resveratrol by exhibiting increased bioavailability (80% compared to 20% in resveratrol) due to the presence of two methoxy groups which cause it to exhibit increased lipophilic and oral absorption.

Pterostilbene and Sirtuins at Thorne.com

Sirtuins are protein enzymes that regulate numerous cellular functions, including aging, inflammation, detoxification, stress resistance, fat and glucose metabolism, circadian rhythms, and mitochondrial biogenesis. In humans and other mammals there are seven different sirtuins (SIRT-1 through SIRT-7) that are involved with different functions and are either directly or indirectly related to longevity.
