L-lysine HCl can improve calcium absorption as well as improvise collagen quality, muscle well-being in general and has helped patients suffering from osteoporosis. It contributes to a positive calcium balance by boosting intestinal calcium absorption and improving the renal conservation of the absorbed calcium.

L-lysine HCl has also been suggested to be used in combination with minocycline hydrochloride, and metronidazole to treat reactive arthritis or bursitis. With common occurrence in young men and women, this disease can be caused by species of Shigella bacteria, species of Salmonella, genitourinary pathogens, Chlamydia trachomatis, Neisseria gonorrhea, Ureaplasma urealyticum, Streptococcus pyogenes etc. L-lysine HCl alone or with other active pharma ingredients can be used to treat Herpes simplex I and II infections which are viral by origin.

Usage of L-lysine HCl independently as well as in compounded form has been reported for nephroprotection when radioactive therapy is conducted especially against cancer. The proximal tubular uptake of radionuclide in the renal pathway is inhibited temporarily due to intravenous infusion of concomitant amino acid like lysine protecting the kidney from the radio toxicity. Treatment with L-lysine HCl has also been reported to be well tolerated and showed a significant decrease in positive symptoms of schizophrenia.

Contraindications/Precautions

L-lysine is broken down in the liver and its supplementation needs an increased elimination of nitrogen from the body. Also, it is known to interference with urea cycle. Patients with impaired hepatic functionality or sensitivity to increase in blood ammonia concentrations are contraindicated for lysine.
