Glutathione (abbreviated GSH) is a tripeptide composed of the three amino acids glutamic acid, cysteine and glycine. Under optimal conditions, the body can produce this important peptide itself. Glutathione is also found in its natural, reduced form in small amounts in numerous foods such as spinach, broccoli, melons and oranges.

How are we different?
The majority of glutathione preparations available on the market are synthetically produced. Our reduced L-glutathione, on the other hand, is 100% produced by non-GMO fermentation of glucose. The result of the complex, highly pure manufacturing process is L-glutathione in its reduced and directly bioactive form.
For the capsule shells we use custom-made HPMC capsules that, unlike most other HPMC and pullulan capsules on the market, are 100% free from controversial additives such as carrageenans and PEG. We then package this product in environmentally friendly amber glass.
