DMAE is another extremely valuable vitamin-like substance that is not widely known. It is a basic building material that the body uses to make acetylcholine, the most generalized neurotransmitter in the body. Small quantities of DMAE are found in fish, but the body usually makes it in a multi-stage synthesis that starts with the amino acid choline, arrives at DMAE at about step number three and ends up finally with acetylcholine.
The body's nerves are wrapped in fatty tissue that should be saturated with acetylcholine. Every time a nerve impulse is transmitted from one nerve cell to the next, a molecule of acetylcholine is consumed. Thus acetylcholine has to be constantly replaced. As the body ages, levels of acetylcholine surrounding the nerves drop and in consequence, the nerves begin to deteriorate. DMAE is rapidly and easily converted into acetylcholine and helps maintain acetylcholine levels in older people at a youthful level.
When laboratory rats are fed DMAE they solve mazes more rapidly, remember better, live about 40 percent longer than rats not fed DMAE and most interestingly, when autopsied, their nervous systems resemble those of a young rat, without any evidence of the usual deterioration of aging. Human nervous systems also deteriorate with age, especially those of people suffering from senility. It is highly probable that DMAE will do the same thing to us. DMAE also smoothes out mood swings in humans and seems to help my husband, Steve, when he has a big writing project. He can keep working without getting 'writers block', fogged out, or rollercoastering.
DMAE is a little hard to find. Prolongevity and VRP sell it in powder form. Since the FDA doesn't know any MDR and since the product is not capped up, the bottle of powder sagely states that one-quarter teaspoonful contains 333 milligrams. Get the hint? DMAE tastes a little like sour salt and one-quarter teaspoonful dissolves readily in water every morning before breakfast, or anytime for that matter. DMAE is also very inexpensive considering what it does. A year's supply costs about $20.
