Glutathione

Glutathione is a powerful antioxidant that occurs naturally in our body. It is a tripeptide composed of the amino acids cysteine, glycine, and glutamine. It plays a key role in many bodily functions, including detoxification, immune system support, neutralization of free radicals, and regeneration of vitamins C and E. Its level in the body is primarily reduced by stress, illness, and aging. Foods rich in components necessary for the production of glutathione include garlic, onions, broccoli, kale, avocado, and nuts. It is also produced as a dietary supplement in the form of glutathione itself or as its precursor, N-acetylcysteine.

Good day,
what is the difference (for a person who wants to purchase this dietary supplement for its antioxidant effects with the expected impact on reducing the body's inflammatory activity) between glutathione and acetyl-glutathione? There is quite a significant price difference.

Standalone glutathione has low bioavailability because hydrochloric acid in the stomach quickly dissolves it. The acetylated form of glutathione has much higher stability, thus a significantly larger amount of this antioxidant reaches the cells.
