Amino Acids and HGH Production

Amino acids are the essential building blocks of our body. They are vital to our health and some of them are strongly linked to HGH or Human Growth Hormone production in our body. Amino acid deficiencies have been clinically linked to allergies, immune system disorders, depression and neurological problems. Generally – amino acid deficiency leads to decreased body and mental function.


Arginine is a semi-essential amino acid. It has numerous positive effects on our body – improved exercise performance, increase in HGH production, positive immune enhancing effects, accelerated recovery etc. A study done at the University of Turin, Italy showed that arginine supplementation leads to an increase in HGH Production. Subjects in the study had three times higher growth hormone levels over the average for their age group.


Ornithine is derived from the amino acid Arginine. High doses of L-Ornithine have successfully raised growth hormone levels in some studies. According to a study (Bucci, L., Hickson, J.F., Pivarnik, J.M., Wolinsky, I., Mc Mahon, J.C. and Turner, S.D. (1990) Ornithine ingestion and growth hormone release in bodybuilders), Ornithine ingestion and growth hormone release in bodybuilders, 50 % of the subjects experienced significant increases in serum growth hormone levels.

When administered together, L-Arginine and L-Ornithine do appear to offer anabolic benefits. These benefits appear to be caused by growth hormone release, but this remains unproven.


L-Lysine is an essential amino acid.When taken together with Arginine L-Lysine can trigger the release of growth hormone.In a study at the University of Rome, 15 healthy male subjects aged 15 to 20 years old, were given 1200 milligrams of Arginine pyroglutamate combined with L-lysine hydrochloride.In all of them there was significantly elevated biologically active growth hormone from two to eight times.


Glycine is a nonessential amino acid. More recent studies have documented that oral glycine can raise growth hormone levels in humans.


Glutamine is the most abundant amino acid in human muscle, directly regulating both the production and wearing-down of protein and immune cell activity.Glutamine is converted into glutamate, which can directly enhance growth hormone secretion.


Gamma-aminobutyric acid (GABA) is the brains major inhibitory neurotransmitter. Studies have shown it is responsible for both the rise of growth hormone (when at rest) or the inhibition of growth hormone (when exercising).(33-35) Oral GABA supplementation has increased growth hormone levels in humans. In one study, a single oral dose of 5 grams of gamma aminobutyric acid administered to 19 subjects significantly elevated plasma growth hormone levels.
