Arginine is an essential amino acid in horses. It is necessary for the removal of ammonia (a toxic byproduct) from the body and the release of certain hormones. It plays a role in wound healing and immune function.

Citrulline is an amino acid that the body can convert into another amino acid, arginine. Since arginine is a precursor to nitric oxide, nitric oxide signals muscles to relax, resulting in increased blood flow to certain areas.
