MOLEQLAR GlyNAC pairs glycine and N-acetyl-cysteine in a 1:1 formula, the two building blocks your body uses to make glutathione, the master antioxidant found in nearly every cell. Rather than supplying glutathione directly, GlyNAC gives your cells the raw materials to produce exactly the amount they need. This self-regulating mechanism supports mitochondrial function and cellular defense against oxidative stress without disrupting the immune system's own use of free radicals. Each batch is independently tested in German laboratories, with certificates published for every batch. Vegan, non-GMO, gluten-free and developed by doctors.
