Recently, published in the middle of the Nutrition & Intermediary metabolism Magazine, a study of resveratrol has found resveratrol could help patients with type 2 diabetes romote blood circulation of the brain. Former research by the team has shown that resveratrol improves vascular function in the bloodstream. Based on that, the researchers concluded that resveratrol also promotes blood flow to the brain.
In the new study, 36 patients with type 2 diabetes aged 40 to 80 years were randomly assigned to take a combination of 75, 150, and 300mg of trans-resveratrol, or a placebo, once a week. The researchers used transcranial doppler ultrasonography to measure the participants' response to hypercarbonic acid stimulation of nonavascular dilatation. Hypercarbonic acid stimulation involves breathing high-carbon gases (such as 95%O2+5%CO2) for three minutes before and after the use of a supplement or placebo for 45 minutes.
The study found that the central artery blood vessels in the left and right brain of each resveratrol supplement group showed vasodilation, and the effect of the 75mg group was the best.
