Experience a new level of convenience with Glutathione-SR’s innovative sustained-release design. This formula delivers a steady supply of glutathione and magnesium, so you can feel supported throughout your day. Magnesium contributes to normal energy-yielding metabolism and the healthy functioning of your nervous system—ideal for anyone with a busy lifestyle or looking for reliable, everyday support. Whether you’re training, working, or simply on the go, Glutathione-SR fits seamlessly into your wellness routine.

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.
