The following report, which is backed up by incredible scientific research, shows the many health benefits of l-arginine in the human body. L-arginine is a semi-essential amino acid, which is produced in the liver and can be found in protein rich foods like red meat. Medical research has now shown that by simply supplementing with 5000 mg of l-arginine everyday all the following is possible:

Aging Process

  • L-arginine inhibits one of the primary mechanisms of the aging process (it inhibits the process of cross-linking). (1)
