Newest resveratrol discovery —
boosts your brain's energy
I know I tell you about resveratrol a lot. But there's good reason for it. This super nutrient is likely a life extender, cancer preventer, weight-loss inducer, circulation protector, and more. Now we find that it encourages better circulation and oxygen extraction within the brain.
A new study says single doses of resveratrol enhance blood flow to the brain during task performances. This was a randomized double-blind placebo controlled crossover study on 22 healthy adults. This is considered the very best kind of medical study.
What's remarkable is that the researchers actually determined oxygen uptake. This is easy to do. Fully oxygenated blood (arterial) is bright red. That's due to oxyhemoglobin. But, when your tissues extract oxygen from the hemoglobin, and burn it, the returning blood is darker. Why? Because the hemoglobin is now stripped of its oxygen (called deoxyhemoglobin) and takes on the darker color of venous blood. The color difference is easy to measure.
The researchers used doses of 250 mg and 500 mg of oral trans-resveratrol. The authors didn't find changes in cognitive function in this short study. But that's not what they were looking to find. They were looking for resveratrol's instant effect on your brain's ability to uptake oxygen. They wanted to know if resveratrol can increase your brain's circulation when you need it most — when you're active.

Since the returning blood was darker, it means that the tissues (brain) pulled off more oxygen from the hemoglobin. That directly translates to more oxygen consumption. And that means greater energy production within the brain. I can't tell you how resveratrol accomplishes this, but it's fantastic news to me. There are a number of degenerative brain conditions out there that could be helped by greater neuronal energy production, including Alzheimer's.
The bioflavonoids in Alginol are likely to do this as well. These complex eight-ring structures from the seaweed cava ecklonia are highly soluble in your brain. In the case of this product, there have been studies on rodents showing improvement in cognitive function and protection against beta amyloid, the toxic stuff that accumulates in the brains of Alzheimer's patients.
So, it appears likely that resveratrol will do similar great things for your brain, and, you have a choice in wonderful bioflavonoids for brain health and protection!
Resveratrol is one of the best nutrients you can take. The scientific research behind it — and the clinical proof — supports its daily use. My favorite brand is from Advanced Bionutritionals.
