The Active Ingredient Is: L-Glutathione

L-Glutathione is a top antioxidant, a tripeptide made from cysteine, glutamic acid and glycine that’s found naturally in your body to help shield cells from oxidative stress.

This blend pairs L-Glutathione with its amino acid precursors and is made in the UK under strict GMP standards, with a hypoallergenic process suitable for vegetarians and vegans.

What L-Glutathione Does?

Glutathione takes part in antioxidant processes and supports detox pathways, helping to keep normal cellular defence against oxidative stress. The included amino acids act as cofactors to support your body's own production and resilience, in line with EFSA-recognised nutrient functions.

Public bodies note the role of glutathione in supporting normal antioxidant status and detox processes, helping contribute to overall cellular balance.
