What is the cousin of resveratrol?
Resveratrol is a well-known antioxidant compound found in red wine, grapes, and berries. But it has a powerful "cousin" in the plant world—pterostilbene. Often called the “better-absorbed” sibling of resveratrol, pterostilbene offers similar health benefits with even greater bioavailability.
Meet Pterostilbene: A Natural Antioxidant
Pterostilbene is a stilbenoid compound primarily found in blueberries and Pterocarpus marsupium. Like resveratrol, it is known for its anti-inflammatory, anti-cancer, and heart-protective properties—but with better absorption and longer presence in the body.
Key Differences Between Resveratrol and Pterostilbene
- ✅ Bioavailability: Pterostilbene is more easily absorbed and stays longer in your system.
- ✅ Structure: Pterostilbene has two methoxy groups, making it more lipophilic.
- ✅ Sources: While resveratrol is common in grapes, pterostilbene is found in blueberries.
