Endurance & Muscle Building
L-Citrulline is an amino acid that plays an important role in nitric oxide (NO) metabolism and regulation. L-Citrulline is converted to L-Arginine in the body to support L-Arginine and nitric oxide levels. Increased production of NO promotes vascular dilation which improves oxygen and blood circulation throughout the body. L-Citrulline is also expected to relieve muscle fatigue through ammonia elimination. Antioxidant action and heart protection action are also known.
Kyowa Quality L-Citrulline has successfully undergone and met the stringent requirements of the USP Dietary Supplements Verification Process.
