Improve Your Memory By Improving Brain Circulation
Resveratrol supplementation has shown to improve executive function and memory in older adults (Thaung Zaw JJ., et.al., 2017).
The benefits were due to improved cerebral perfusion, circulation in the brain.
When 80 post-menopausal women were supplementing with trans-resveratrol or a placebo for 14 weeks, the researchers found that the women taking the resveratrol had significant improvements in verbal memory and overall cognitive function (Evans HM, et.al., 2017).
The researchers also measured cerebrovascular responsiveness and found an increase of 17% in the women taking resveratrol.
The dosage producing the improvements was low.
Only 75 mg of resveratrol taken twice a day was required to produce the results.
Post-menopausal women are at a higher risk for memory loss because of hormonal changes.
The bioavailability of resveratrol is low. That can, however, be greatly improved by using a methylated form of resveratrol (Wen X, Walle T, 2017).

Resveratrol is found in the skin of grapes, but also in other various plants. It is known as an antioxidant and got a lot of attention when a study on mice showed that resveratrol increased their lifespan spite of a high fat, high-calorie diet. Some of the changes included improved insulin sensitivity, increased number of mitochondria (the energy producing entity of the cell) and improved motor function (they moved better).
