Arginine is an amino acid and it is a precursor to nitric oxide (NO).
It helps reduce healing time of injuries, especially bone injuries (as it increases collagen). It also reduces the healing time for damaged tissue.
It is popular as a bodybuilding supplement for weight lifting and increased muscle mass.
It is also used as a sexual health supplement as it can support erectile function, libido and stamina.
This supplement is normally obtained through diet from a number of healthy foods.
But if injured from burns, broken bones and for wounds, eating more Arginine rich foods and supplements may be needed.
