What Does L-Glutamine Do?

L-glutamine helps support muscle recovery and immune cell function after intense activity, and it may contribute to gut health in relation to intestinal barrier support, in line with EFSA-aligned understanding of amino acid roles. NHS and EFSA guidance emphasise normal cellular metabolism and immune support as typical functions of glutamine.

Dr. Lemon from a university found that, at proper intake levels, L-glutamine acts as a primary fuel for rapidly growing cells of the immune system and GI tract, supporting normal function.
