L-Arginine is involved in several different functions in the body which include wound healing, helping the kidneys remove waste products from the body, maintaining immune and hormone function, dilating and relaxing the arteries.
L-Citrulline boosts nitric oxide production in the body. Nitric oxide helps your arteries relax and work better, which improves blood flow throughout your body. This may help treat or prevent many diseases. L-citrulline supplements may ease symptoms of mild-to-moderate erectile dysfunction (ED) too.
