Resveratrol May Slow Memory Loss
A decline in memory performance is common as people age but a recent study suggests that taking a resveratrol supplement may boost memory function in mature adults.
Participants in the study included 46 men and women between the ages of 50 and 75. Over the course of 26 weeks they were given either 200 mg of resveratrol or a placebo.
The researchers administered memory tests and neuroimaging at the onset and conclusion of the study. They found that the resveratrol supplements were associated with a significant improvement in word retention over 30 minutes when compared with the placebo.
The neuroimaging tests revealed that there was increased functional connectivity between sections of the hippocampus, with is the part of the brain that controls memory. Additionally, the resveratrol group had lower levers of glycated hemoglobin when compared with the placebo group. Glycated hemoglobin is a marker of long-term presence of excess glucose in the blood.
Researchers from Charité-Universitätsmedizin Berlin and the Max Planck Institute for Human Cognitive and Brain Sciences conducted these study. It was published in the Journal of Neuroscience on June 4, 2014.
Previous studies have shown resveratrol to be a powerful antioxidant with health benefits that include increasing energy levels, improving brain health, reducing the appearance of aging, improving metabolism, and improving liver function.
This antioxidant can be found in red wine, grapes, grape seed extract, and peanuts. A glass of red wine a day can provide a good amount of resveratrol, but excess drinking may counter balance the positive health benefits. Another good way to get resveratrol is through a high quality supplement.
