Why it works

Glutamine is the most abundant amino acid in muscle and in blood plasma, and the cells that line the gut use it as a primary fuel. The body makes its own, but daily hard training, long sessions, and contact sport draw on that pool faster than it refills.

This is free-form L-glutamine and nothing else, 3.15 g in a small scoop with silicon dioxide as a flow agent. It is unflavored, so it goes into water, a protein shake, or an electrolyte drink without changing the taste.

Benefits

Muscle recovery*

Glutamine is the amino acid muscle gives up first under a heavy training load. A daily scoop supports normal muscle recovery between sessions.*

Digestive integrity*

The cells lining the small intestine use glutamine as a primary fuel, so adequate intake supports digestive integrity.*

Immune support*

Immune cells draw on the same glutamine pool as muscle. Keeping it topped up supports normal immune function through a heavy training block.*

One ingredient*

Free-form L-glutamine with nothing but a flow agent, so it drops into a routine without changing anything else in it.*
