Anti-Aging Supplement Psphatidylserine looks more like one of those unpronounceable ingredients listed on the label of a hair shampoo. But actually, it's brimming with promise. This natural supplement is on the cutting edge of anti aging medicine. It has been shown to renew brain cells and sharpen mental performance.Where can you find this exotic stuff?

It's sitting on a shelf at your local health food store or just a click away on the Internet, along with other exciting, cutting edge anti aging substances that you may not know much about yet. Among them are alpha lipoic acid, coenzyme Q01 and melatonin, to name just a few.

"I'm sure these supplements seem somewhat mysterious," says Ronald Klatz, M.D., D.O., author of Brain Fitness and president of the American Academy of Anti-Aging Medicine, a Chicago based society of physicians and scientists who believe aging is not inevitable. "After all, we've known about the role of vitamin C in good health for the past 30 years, and vitamin E for longer than that. These are quite new."

What makes these Supplements so special?

For one thing, many of them are potent antioxidants, says Dr. Klatz. Only antioxidants can neutralize free radicals, the unstable oxygen molecules that punch holes in cell membranes, destroy vital enzymes, damage cellular DNA and, ultimately, lead to the diseases of aging.

For another, their antioxidant power is, in some cases, many times more powerful than better known antioxidants such as vitamins C and E. Some actually recycle vitamins C and E, giving them new life in the endless war against free radicals. Still others dissolve in both fat and water, enabling them to neutralize free radicals wherever they occur, from our watery blood to our fatty brains.

These new supplements have the potential to extend life span and stave off age related degenerative diseases, says Dr. Klatz. Future youth is out there!
