Arguably the most popular of the 20 amino acids and naturally occurring in protein, which helps to build and repair new muscle¹ — it’s important for all fitness goals.

L-Glutamine is an amino acid that the body is only able to make in small amounts, so we must get some from our diet. So whether you’re lifting weights or powering through cardio, our super-convenient L-Glutamine Elite is great for getting the glutamine you need.
