Pterostilbene promotes blood circulation in the brain, improves cognitive function
Recently, a study from Journal of Nutrition & Intermediary Metabolism show that for most type II diabetic patients, pterostilbene promotes their blood circulation in the brain, improves cognitive function
This study indicates the optimal dose to improve vascular dilatation, especially for the brain blood vessels of type II diabetic patients. According to the existing researches, type II diabetic patients are usually associated with endothelial dysfunction and subclinical cognitive impairment.
Before this study , researchers have known that pterostilbene can improve vascular function in the blood circulation system , and basing on this fact , they deduced this supplement also boosts blood circulation in the brain .Researchers recruited 36 type II diabetic patients with the age from 40 to 80 year old , these patients took 75mg,150mg and 300mg pterostilbene or placebo randomly , once a week . Meanwhile, researchers tested patients’ vasodilatation response to high carbonic acid stimulation by Transcranial doppler ultrasonography . The method of high carbonic acid stimulation involves breathing high carbon gas (such as 95%O2+5%CO2) for three minutes before and after using a supplement pterostilbene or placebo 45 minutes.
This tests suggest that the central arteries of left and right brain of all patients who took pterostilbene supplement showed vasodilatation, furthermore, the 75mg group worked best. Previous studies have shown that augmented vasodilatation is effective in relieving endothelial dysfunction and subclinical cognitive impairment. Therefore, researchers concluded that pterostilbene improves cognitive function
In addition , this wonder supplement other main functions are also getting attention :
Atherosclerosis is a common disease cause as we age characterized by the build up of plaque in the arteries. It tends to worsen as we age and significantly increases the risk of heart attack or stroke. Studies on mice have found that taking this supplement may protect the artery walls from this build up of plaque and thus reduce the potential for heart attacks or strokes
In tests on human cells and on mice, scientists demonstrated that pterostilbene may inhibit the buildup of LDL cholesterol, or bad cholesterol. The study also found that pterostilbene may help fight oxidative stress, a destructive biological process thought to be a key factor in the development of heart disease.
Also , pterostilbene can also reduce the antioxidant defense of the body’s unhealthy cells or cancerous cells. Studies done so far have showed that it is effective against breast cancer, colon cancer, lung cancer and prostate cancer.
