Longevity Q-100 - The ingredients

Longevity Q-100 contains a specific combination of amino acids that have been shown to increase the potential for the body’s own growth hormone releasing agents, often called precursors or secretagogues, to stimulate the pituitary gland to produce and release more of its own growth hormone. The effect on the body is to lessen the effect of some factors thought to be related to aging.

The four amino acid combination in the product include: L-Arginine, L-Glutamine, L-Ornithine and L-Glycine.


  • It is an essential amino acid, meaning that the body cannot create this amino acid on its own; it must get it from the foods that we eat.

  • L-Arginine’s main role in the product is to stimulate the secretion of growth hormone, which in turn results in increasing fat burning, the building of muscle tissue, boosting immunity, protecting the liver and detoxifying harmful substances.  Some studies have shown that it has positive effects in restoring sexual function in impotent men.  There is no doubt that L-Arginine causes the secretion of growth hormone.  Dirk Pearson and Sandy Shaw recommended L-Arginine and L-Ornithine as GH releasers in their book "LifeExtension: A Practical Approach".   A number of clinical studies on various doses of L-Arginine and L-Arginine in combination with Lysine have shown widely varying effects on growth hormone including a synergistic increase in GH.

  • As mentioned above, it also restores sexual function in impotent men.  In a 1994 study by doctors. A.W. Zorgniotti and E.F. Lizza of the department of urology/surgery at New York University School of Medicine, six of fifteen men taking L-Arginine had renewed sexual performance, specifically improved erection, yet none of the men on the placebo enjoyed the same results. The researchers believe that L-Arginine worked because it is a precursor of nitric oxide, which plays a key role in initiating and maintaining an erection. 


  • L-Glutamine is the amino acid that is most used by the body, particularly during times of stress. The immune system and the gut need and thrive on L-Glutamine. If the body does not produce enough L-Glutamine, muscle loss and immune dysfunction can occur.  L-Glutamine is a key to the metabolism and maintenance of muscle.  It is the primary energy source for the immune system, and is essential for DNA synthesis, cell division, and cell growth, all factors that are enhanced by Growth Hormone.  Therefore, L-Glutamine’s role in the product is to support protein synthesis in muscles, prevent the breakdown of muscle tissue, support a healthy immune system, and replenish muscle glycogen.

  • L-Glutamine is the latest amino acid to generate excitement as a GH-releaser thanks to a 1995 study by Thomas C. Welbourne of Louisiana State University College of Medicine in Shreveport.  Welbourne showed that a surprisingly small oral dose of L-Glutamine raised growth hormone levels more than four times over that of a placebo. Even more exciting, age did not diminish the response at least in this small study of volunteers, who ranged from thirty-two to sixty-four years.

  • When the gut atrophies, nutrients of all kinds cannot be absorbed as well as before. A 1993 study by Welbourne in animals showed that L-Glutamine supplementation protects muscle mass and prevents acidosis which occurs with strenuous exercise and causes muscle breakdown.  According to Judy Shabert, M.D. author of "The Ultimate Nutrient Glutamine", supplementation with glutamine, especially in times of stress, would prevent muscle wasting. In a foreword to the book, Douglas Wilmore, M.D., of Harvard Medical School, points out that glutamine is a key to the metabolism and maintenance of muscle, the primary energy source for the immune system, and is essential for DNA synthesis, cell division, and cell growth, all factors that are enhanced by growth hormone. It also crosses the blood-brain barrier into the brain, where it increases energy and mental alertness.


  • This is a nutrient that consists of Ornithine bound with two molecules of alpha ketogutarate.  L-Ornithine also has growth hormone stimulating effects.  Furthermore, it is a precursor to glutamine thus boosting glutamine levels.


  • It is a non-essential amino acid. Two studies found that this amino acid increases growth hormone in the serum.  In one, it caused a three-fold increase, while a Japanese research team showed a ten times increase over baseline in patients who had gastric surgery.

  • It may be useful in dampening hyperactive brain activity that produces spasms. In one study, it significantly reduced spasms in all ten patients with severe chronic spasticity in the legs, including seven with multiple sclerosis.

  • L-Glycine has been shown to have an inhibitory effect on the central nervous system, acting as an antagonist at the glutamate receptor N-methyl-D-aspartate.  L-Glycine has been used in areas such as memory enhancement.  Therefore, L-Glycine’s role is mainly to increase memory and cognitive function, factors that usually decrease as part of the aging process.


Ronald Klatz, research medical scientist and author of "Grow Young with HGH" states that there is a reason to believe combining L-Arginine, L-Glutamine, L-Ornithine and Lysine (Longevity Q - 100 formula replaces lysine with L-Glycine) will have a synergetic effect. Giampapa, medical director at Longevity Institute International, in Montclair, N.J., has followed the beneficial changes that growth hormone agonists have made in hundreds of age related GH hormone deficient individuals.
