What Is Pterostilbene?
Pterostilbene is a naturally occurring polyphenol found predominantly in blueberries and the heartwood of Pterocarpus marsupium. It is a methylated structural analog of resveratrol (CAS 537-42-8), and this small chemical modification makes a significant practical difference: pterostilbene shows substantially higher oral bioavailability, longer half-life, and better membrane permeability than its parent compound. Supplied as a white to off-white crystalline powder with purity of 98% or higher, it has become one of the most sought-after actives in the fast-growing longevity and healthy-aging nutrition segment.
How It Works
Pterostilbene is a potent activator of the Nrf2 pathway, upregulating the body’s endogenous antioxidant defenses, and it supports SIRT1 activity — one of the key mechanisms associated with cellular longevity. Its methoxy groups reduce rapid metabolism by phase II enzymes, allowing lower doses to deliver sustained plasma levels. In formulation studies, pterostilbene also demonstrates stronger anti-inflammatory modulation and lipid-metabolism support compared with resveratrol at equivalent intakes.
Key Applications
- Longevity and healthy-aging supplements — often stacked with NMN, resveratrol, and spermidine in NAD+ support and senolytic formulations.
- Cognitive health products — crosses the blood-brain barrier and is studied for memory, focus, and neuroprotection support.
- Cardiovascular and metabolic support — formulation into capsules and softgels targeting healthy lipid and glucose metabolism.
- Premium beauty-from-within products — antioxidant support for skin health in nutricosmetic blends.
- Functional foods and beverages — stable, taste-neutral powdered active for fortified drinks, gummies, and stick packs.
