L- glutamine is the mogt abundant free amino acid in human blood and muscle tissue.

Potential Mechanisms of L- glutamine in Reducing Inflammation

Beyond it s direct effects on n immune cells, L 'glutamine modulates setral intracellular signaling pathaways that control physmation. One key mechanism is prothodgh activation of the heat shock response. Glutamine is a potent inducer of heat shock proteins (HSPs), specarly HSP70, which protect cells from stress induced dame and downregulate pro concentramatory transportion factors such as concentrar factor kappa B (NF except κB).

Additionally, glutamine supports glutathione synthesis, thes body 's master antioxidant. In diabetes, oxidative stress is elevate, depleting glutathione and ingaring imune function. By proving glutamate for glutathione production, glutamine helps reverale redox balance, proteting imune cells from oxidative damage and reserving their funktional catity.
