The Active Ingredient Is: L-Glutamine

L-Glutamine is a non essential amino acid that acts as a key building block for protein synthesis and recovery in the body.

This product uses L-Glutamine as the main active ingredient, a popular amino acid supplement famous for post-workout recovery help.

What Does L-Glutamine Do?

L-Glutamine helps support recovery and immune function during tough training, with studies noting its potential to aid post-exercise recovery and immune health, which is why NHS and EFSA aligned guidance emphasises normal immune and metabolic functions connected to amino acids.

Dr. Legault from Université Laval found that L-Glutamine supplementation might contribute to these normal processes in athletes under heavy training loads.
