Glutamine

What it is: An amino acid the body makes and uses for energy and to build protein.

Stop Guessing Your Dosages.

Balancing dosages across multiple different bottles is risky, inefficient, and expensive. Glutamine is already lab-dosed and delivered daily in our Gut Pack — one less bottle to manage.
