L-Citrulline is an amino acid that numerous health and athletic performance benefits.

During the past decade research on L-Citrulline has shown to play an important role in nitric oxide production, vascular health, muscle protein synthesis, ammonia elimination and immune function.*

L-Citrulline is converted to L-Arginine in the body to support L-Arginine and nitric oxide levels. Increased production of nitric oxide promotes vascular dilation which improves oxygen and blood circulation throughout the body. L-Citrulline can also support heart health.*

L-Citrulline can also relieve muscle fatigue through ammonia elimination. L-Citrulline helps to rid the body of ammonia, a toxic byproduct of protein metabolism and provides a readily available substrate for arginine production. L-Citrulline is involved in the formation of urea in the liver which plays an important part in the removal of waste created by the digestion, absorption and metabolism of proteins.*
