What Does Pterostilbene Do?

Silbinol® is a 100% natural trans-Pterostilbene extracted from the heart wood of Pterocarpus marsupium. Pterostilbene is the primary antioxidant in blueberries and a methylated form of resveratrol that exhibits better bioavailability than resveratrol.* trans-Pterostilbene may be referred to as a calorie-restriction mimetic due to its ability to activate sirtuin enzymes that are also activated by caloric restriction, fasting and exercise.* Sirtuins support healthy aging by regulating gene expression, DNA repair, mitochondrial function and energy metabolism.*
