Ingredients
Pterostilbene is a naturally occurring stilbene polyphenol structurally related to resveratrol. It is found in foods and plants including blueberries, grapes, peanuts, and Pterocarpus marsupium. Pterostilbene is studied for its antioxidant and other biological properties. The source, purity, concentration, and additional ingredients vary by supplement manufacturer.
Pterostilbene is a naturally occurring polyphenolic compound belonging to the stilbene family. It is chemically related to resveratrol and is found naturally in several plant sources, particularly blueberries and certain other fruits and plants.
Pterostilbene has attracted scientific interest because of its antioxidant properties and biological activity. Research has investigated the compound in areas including oxidative balance, metabolic health, cardiovascular nutrition, cognitive research, and healthy-aging pathways. However, evidence varies by study, and many findings come from laboratory or preclinical research.
Pterostilbene may be used in dietary supplements as a standalone ingredient or combined with resveratrol, grape extracts, blueberry compounds, nicotinamide riboside (NR), or other polyphenols. The exact amount and formulation depend on the finished product.
Because research studies use different doses and formulations, there is no universal serving amount that applies to every Pterostilbene supplement. Consumers should check the product label for the exact pterostilbene content, source, serving size, and additional ingredients.
