BioTechUSA 100% L-Glutamine 240g

Glutamine is usually sold as a muscle supplement, which undersells what it actually does. Your muscles hold the largest store of it, but they are not the biggest consumers - the cells lining your gut and your immune cells both run heavily on glutamine, and they get first call.

That competition is why hard training depletes it so quickly. When physical stress raises demand across all three systems at once, the reserve in your muscle tissue is what gets drawn down to cover it. BioTechUSA 100% L-Glutamine replaces that reserve with a pure 5000mg dose per serving and nothing else in the tub - no fillers, no flavouring, no bulking agents. It supports recovery between sessions and normal immune system function.

The 240G tub holds 48 servings, a little over six weeks of daily use.

It is unflavoured, so it stirs into a post-workout shake or plain water without changing the taste.
