Keep Your Brain Sharp Forever

Have you heard of the nutrient Astaxanthin? Joseph Mercola says its antioxidant powers blow away vitamins C and E.

... A Natural Way to Prevent Dementia?

Astaxanthin exhibits exceptionally potent free-radical scavenging activity, and protects your cells, organs and body tissues from oxidative damage. In this way it impacts many aspects of health, but one of the most exciting could be its impact on your brain. In fact it is hundreds of times more effective than vitamin E in squelching singlet oxygen free radicals.

People with dementia tend to accumulate abnormal levels of phospholipid hydroperoxides (PLOOH) in their red blood cells. But new research published in the British Journal of Nutrition found that taking 6 mg or 12 mg of astaxanthin daily for 12 weeks lowered blood levels of PLOOH by 40 and 50 percent, respectively.

Researchers concluded that the improved antioxidant status and decreased PLOOH levels in the red blood cells may contribute to the prevention of dementia.

Astaxanthin is a fat soluble nutrient and readily crosses your blood-brain barrier, and a past study found it may help prevent neurodegeneration associated with oxidative stress as well as make a potent natural brain food. Read more
