Pterostilbene is a naturally occurring compound that belongs to the stilbene class of chemicals. It is structurally similar to resveratrol, another well-known stilbene, but has a few distinct differences that may offer unique benefits. Pterostilbene is found in small quantities in foods such as blueberries, grapes, and some types of nuts. It has gained attention for its potential antioxidant, anti-inflammatory, and anti-cancer properties. Research suggests that pterostilbene may support cardiovascular health, improve cognitive function, and help manage blood sugar levels. Its higher bioavailability compared to resveratrol means that it may be more efficiently absorbed and utilized by the body. However, more research is needed to fully understand its effects and potential health benefits.
