Isidori: combination of L-arginine and L-lysine induces production of growth hormone. Each of the amino acids apart does not give a positive result!

Isidori A, Lo Monaco A, Cappa M. A study of growth hormone release in man after oral administration of amino acids. Curr Med Res Opin. 1981;7:475–81. [PubMed]

A study was carried out in 15 male volunteers to evaluate qualitatively the secretion of growth factors following stimulation by oral amino acids. The results showed that oral administration of a combination of two amino acids (1200 mg 1-lysine plus 1200 mg 1-arginine) provoked a release of pituitary somatotropin and insulin. This phenomenon was reproducible and the growth hormone secreted in response to this stimulation had biological activity (as demonstrated by a radioreceptor assay and somatomedin induction). The effect appeared to be specific to the combination of the two amino acids; neither of the amino acids demonstrated appreciable stimulating activity when administered alone, even at the same doses.

Conclusion
Arginine’s involvement as a precursor of creatine and its potential to increase endogenous growth hormone makes it a popular supplement among those who wish to improve their physical performance. The choice to supplement with arginine is also based on sound physiologic theory.


Anti-aging effects of L-arginine

Conclusions:
Many – if not all – of the body functions described in this text are debilitated by aging. Studies have shown that L-arginine, through its versatile metabolic and physiological pathways, can improve many of these functions. To summarise some of its effects; L-arginine is involved in the production of a variety of enzymes, hormones, and structural proteins. It facilitates the release of growth hormone, insulin, glucagon, and prolactin. It is a component of the hormone vasopressin, produced by the pituitary gland. It is the physiological precursor of diverse biological compounds such as nitric oxide, polyamines, proline, glutamate, creatine, agmatine and urea. As a booster of immunity, arginine stimulates the thymus and promotes lymphocyte production.
