A recent study showed that moderate doses of the polyphenol resveratrol increased blood flow and thereby oxygen to the brain of test subjects.
Resveratrol is a powerful polyphenol found in red wine and in high amounts in certain other plants. Resveratrol has demonstrated antioxidant, anti-cancer and longevity properties in various studies and experiments.
The Problem - You'd have to drink bottles of wine to benefit from the amounts of Resveratrol in wine. Why is this a problem? Well, you would undoubtedly wake up with aweful hangovers each morning, and your caloric intake certainly wouldn't help the waistline.
The Solution - Enjoy a glass or two every so often, but I recommend taking a daily dose of Isotonix Resveratrol in order to truly benefit from this powerful polyphenol.
