Pterostilbene is the active ingredient of heart wood from Pterocarpus marsupium (Indian Kino Tree). The heart wood is used as an astringent and in the treatment of inflammation and diabetes. Pterostilbene is a stilbenoid chemically related to resveratrol and is found in blueberries and grapes. It belongs to the group of phytoalexins, agents produced by plants to fight infections. Based on animal studies it is thought to exhibit anti-cancer, anti-hypercholesterolemia, anti-hypertriglyceridemia properties, as well as fight off and reverse cognitive decline. It is believed that the compound also has anti-diabetic properties.

🌿 Health Benefits of Pterostilbene
✅ Blood sugar regulation
✅ Cholesterol and lipid control
✅ Anti-cancer potential
✅ Cognitive function and anti-aging
✅ Antioxidant protection
🔬 1. Blood Sugar & Anti-Diabetic Effect
Animal studies have shown that pterostilbene can lower blood glucose levels by up to 56%, while also restoring insulin and hemoglobin to near-normal levels. It enhances antioxidant enzyme activity in the liver and kidneys, reducing oxidative stress in diabetic conditions.
(Pari, 2006; Manickam, 1997)
“Chronic treatment significantly reversed diabetic damage in rats’ organs.”
🛡 2. Antioxidant Protection
Pterostilbene effectively scavenges harmful free radicals. It demonstrates significant in vitro antioxidant activity, with an EC50 of approximately 30 μM (~7.68 μg/ml), comparable to resveratrol.
(Manickam, 1997)
🧪 3. Anti-Cancer Potential
Research indicates that pterostilbene inhibits cytochrome P450 enzymes involved in cancer activation. In rat and mouse models, it showed stronger anti-cancer activity than resveratrol.
(Rimando, 2002)
💓 4. Cholesterol & Lipid Control
Pterostilbene activates PPAR receptors that regulate lipid metabolism. In animal studies, blueberry-based diets high in pterostilbene reduced blood cholesterol levels more effectively than ciprofibrate, a commonly used lipid-lowering drug.
(Satheesh, 2008)
🧠 5. Cognitive and Anti-Aging Benefits
Studies involving aged rats demonstrated that pterostilbene supplementation reversed age-related cognitive decline, improving memory and learning ability.
