L-Glutamine = THE BRAIN FUEL
Test have shown that glutamine acid, a "non-essential" amino acid, improves intelligence, speeds the healing of ulcers, gives a "lift" from fatigue, and helps control alcoholism, schizophrenia and the craving for sweets. The problem is that in order to get more of this amino acid into the brain where it becomes a high-energy brain fuel, we have to use a little nutritional ingenuity. More glutamic acid in the brain might make you smarter, if you're smart enough to figure out how to get more glutamic acid into the brain.
The brain has a protective barrier that lets in only a very, very few chemicals. Glutamic acid, 'like all amino acids with but one exception, is poorly carried across the protective blood barrier of the brain. Even when you eat more glutamic acid, little more ends up in the brain. The body can make other compounds out of the amino acids and, some of these new compounds can cross the barrier.
Thus the brain can make some glutamic acid out of other chemical building blocks that are transported into the brain, and some glutamic acid can cross the barrier.
When the proper building blocks are not in the diet in sufficient quantities or the individual is not efficient in making glutamic acid in the brain, or has problems in carrying glutamic acid across the barrier, that person never is as efficient as he or she could be. Other more serious problems may be caused.
Tests have shown that some people benefit from additional glutamic acid in the brain, but few researchers know how to get it there. Dr. Roger Williams in "Nutrition Against Disease" tells of the limited success of one researcher who administered glutamic acid to retarded children and schizophrenics and wonders what greater improvement would have been obtained if the investigator had only known that another amino acid, the amide form of glutamic acid called L-glutamic acid, can readily. cross the blood-barrier into the brain where it is quickly converted into glutamic acid. .
. Although feeding large amounts of glutamic acid produces only a trivial elevation of glutamic acid in the brain, feeding moderate amounts of L-glutamine produces marked elevation of glutamic acid in the brain.
Glutamic Acid Function
Glutamic acid has a unique function in brain metabolism that makes it of major importance. Glutamic acid is not made into brain chemicals called neurotransmitters, as are some amino acids, nor is glutamic acid incorporated into a protein structure in the brain.
Glutamic acid has two major functions. The unique surprise is that glutamic acid serves primarily as a fuel for the brain, a feat which only one other compound, glucose (blood sugar) can perform.
The second major function of glutamic acid is that throughout the body, glutamic acid with its ability to pick up excess ammonia and be converted to glutamine, serves as a buffer against excess ammonia and in regulating the compounds that enter into a series of vital reactions, called the "citric acid cycle.”
The relationship of glutamic acid to glucose goes beyond their brain fuel interrelationship. Glutamic acid restores hypoglycemic patients in insulin coma to consciousness at a lower blood sugar level than when glucose alone is used.
The brain can store only a small reserve of glucose. Therefore the brain is very dependent on the second-to-second supply of blood sugar. This explains the dizziness and other nervous symptoms in hypoglycemics.
Glutamic acid is the only other compound used for energy by the brain. The gray matter in the brain contains a special enzyme compound that regulates brain cell activity. Glutamic acid is used in a special high-energy reaction that by-passes the normal energy producing chemistry of the citric acid cycle.
Thus a shortage of L-glutamine in the diet or glutamic acid in the brain results in brain damage due to excess ammonia or a brain that can never get into "high-gear".
Dr. Roger Williams has been the pioneer in L-glutamine point out that his colleagues at the Clayton Foundation for Research at the University of Texas made the initial discovery that aroused his own interest. Dr. William Shive discovered that L-glutamine protected bacteria cells against poisoning by alcohol. Then Dr. Williams, along with is associates, Drs. L. L. Rogers and R. B. Pelton, made the all important observation that not only did L-glutamine protect rats against the poisonous effects of alcohol; it stopped their craving for alcohol.
This property of L-glutamine has been studied carefully and its effect cannot be questioned. It has been compared with its chemical relatives glutamic acid, asparagin and the simpler amino acid glycine. These other substances had no effect whatever, but L-glutamine consistently decreased alcohol consumption.
One alcoholic stopped drinking when L-glutamine was administered daily without the patient's knowledge. (L-glutamine is tasteless and can be mixed with food or water without detection.) Two years later the patient was still free from the craving for alcohol.

[Energy & Fitness]
How it Works:
L-Glutamine is an amino acid (a protein building block) that is important in supplying the brain with energy. Its main function is to support cellular growth, energy and repair. It also helps with muscle pain (from exercise).
