What is L-Arginine & L-Citrulline? L-Arginine is a conditionally essential amino acid, while L-Citrulline is a non-essential amino acid. Both work together to help support your lifestyle. While amino acids can be obtained through certain food sources, it may be difficult to receive a concentrated dose, so many turn to a supplement for additional support. Supplement forms include pills, capsules, chewable tablets, bulk powders, lozenges, sprays, liquid drops, chews, gummies, and more.
