What is L-Arginine & L-Citrulline?
L-Arginine is an 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, which is why many people turn to a supplement for additional support.

How to Get Amino Acids:
You can now find L Arginine and L-Citrulline in various forms such as pills, capsules, chewable tablets, lozenges, bulk powders, liquid drops, gummies, and more. Looking for a high quality formula that best suits your daily regimen?
