Glutamine is an amino acid that works better with arginine rather than on its own. I’ve been taking glutamine, arginine and lysine for a while now, and results have been quite satisfactory. I feel more energetic, and have been maintaining my weight at a steady pace, whilst working out 4-5 times in a week. These amino acids are not the only thing I’m taking though, but anything that serves to raise HGH levels for me, is game in my book.
Some info on glutamine: Glutamine is actually the most abundant amino acid found in the human body, and it is not an essential amino acid, because the body manufactures it on its own. But if you exercise, than you will find you probably need extra glutamine, because the body needs additional glutamine after undergoing stress due to immune suppression. Glutamine is needed for maintaining muscle mass and protecting the immune system caused by vigorous exercise.
Glutamine also promotes brain function. It is a component of GABA, which the body converts from glutamate, which in turn, originates from glutamine. Additionally, glutamine helps the gastrointestinal tract in functioning, and has been used in cases of irritable bowel function.
As a promoter of human growth hormone (HGH), glutamine is indispensable. Unlike arginine, which shows some diminished effectiveness in older people, glutamine does not seem affected by age, and according to tests, can raise HGH levels by more than four times (Dr Tomas Welbourne, Am J Clin Nutr, 1995).
Doses most often used for glutamine are between 2-10 grams. I personally take 2-4 grams a day. The higher end of the range doses are most often broken down into separate doses. Glutamine is best taken combined with other amino acids like arginine, lysine and ornithine. This combining of amino acids is referred to as an amino acid stack. The best time to take an amino acid stack is before exercise and sleep. Make sure you take it on an empty stomach, as that is when your insulin levels are lowest.
What are the best natural food sources for glutamine? Glutamine is naturally found in dairy products, meat, fish, eggs, soy, beans, legumes and just about any other high protein foods. Like other amino acids, glutamine is generally not harmful to the body even if taken in large doses, but care and restraint must always be shown at all times. The exceptions are people with kidney problems, who are not advised to take glutamine or any amino acid for that matter, as this will overload the kidneys.
