It plays a role in metabolism of amino acids and is a necessary co-factor in the folate cycle, lack of which can lead to anemia

Protect from light and avoid repeated freeze-thaw cycles

High purity Acetyl L-glutathione powder S-Acetyl-L-Glutathione is the major endogenous antioxidant produced by the cells, participating directly in the neutralization of free radicals and reactive oxygen compounds, as well as maintaining exogenous antioxidants such as vitamins C and E in their reduced (active) forms

Each freeze-thaw cycle creates ice crystals that can physically disrupt peptide structure, and the process concentrates the peptide at the boundary between frozen and unfrozen regions, potentially causing aggregation
