Glutathione dosage protocols leverage this master antioxidant tripeptide (γ-L-glutamyl-L-cysteinyl-glycine) to support cellular detoxification, reduce oxidative stress, and maintain redox balance throughout the body. As the most abundant intracellular thiol, glutathione plays a central role in neutralizing free radicals, supporting liver function, enhancing immune cell activity, and protecting against environmental toxins. This educational protocol presents a subcutaneous injection approach using a practical dilution for clear insulin-syringe measurements.
