Glutathione is an antioxidant that prevents cellular damage and plays a vital role in many cellular processes. Low levels of glutathione can contribute to oxidative stress and reduce nitric oxide (NO) production, which may impact erectile function. While glutathione supplementation is challenging due to limited absorption through the gastrointestinal tract, it can be effectively administered intravenously. Consult with a healthcare professional for guidance on glutathione supplementation.
