L-lysine and L-tyrosine in combination with L-alanine and L-glutamic acid are beneficial for multiple sclerosis, or MS. The combination of these amino acids downplays immune responses that promote inflammation. L-tyrosine and L-lysine together with L-alanine and L-glutamic acid help to regulate your immune system and increase your antibody production when exposed to viruses, bacteria and other foreign matter. Oliver Neuhaus and colleagues tested the use of copolymer-1, which contains all four amino acids in lower inflammation and regulates the formation of antibodies. Downplaying inflammation helped to protect nerve coverings of MS patients, thereby preserving nerve function and motor skills.
