What it does
Glutathione is often called the body's master antioxidant: it's made inside your cells and helps neutralize damage and support the liver's natural detox pathways. Levels can dip with age, stress, and illness. Worth knowing: plain oral glutathione absorbs poorly, so well-formulated versions (liposomal or paired with its building blocks) matter for it to actually reach your cells.
The science
Glutathione is the body's master antioxidant and primary detoxification agent. Levels decline with age, stress, and poor diet, leaving cells vulnerable to oxidative damage.
Most relevant for
Antioxidant and liver support. Choose a high-absorption (e.g. liposomal) form.
