Glutathione-SR is a superior choice for glutathione supplementation due to its innovative sustained-release formula. Unlike standard glutathione supplements, Glutathione-SR is designed to protect the nutrient from stomach acid and digestive enzymes, ensuring a slower, more consistent release into the bloodstream. This approach provides steady antioxidant support throughout the day, optimising the benefits of this essential nutrient for liver function, immune health, and overall wellbeing.

For athletes, Glutathione-SR offers an additional layer of assurance with its NSF Certified for Sport® certification. This rigorous testing guarantees that every batch meets label claims and is free from over 200 substances banned by major athletic organisations, including stimulants, narcotics, and steroids. This certification ensures that athletes can trust Glutathione-SR to be both effective and compliant, making it a reliable choice for those seeking peak performance and safety.
