Peptide therapy, including peptide drugs, and innovative supplements like Larazotide and Guttides, which work to restore gut integrity and optimize function
The short answer is that traditional oral glutathione has very low bioavailability
The clinical evidence base supports its use as a tool for maintaining antioxidant status, supporting liver and immune function, and reducing oxidative burden, particularly in individuals whose endogenous production is compromised by age, chronic stress, illness, or inadequate nutrient precursor availability
Injectable or oral peptides could lead to mild gut issues as well, like gas, bloating or diarrhoea
Animal data provides biological plausibility and mechanistic insights but cannot guarantee human efficacy
