Science Facts


Max has the most effective Glutathione enhancement products in the world. Glutathione is present in almost all cells — trillions — and is widely known as the Master Antioxidant, protecting cells from invaders that enter the bloodstream.

Glutathione combats environmental toxins, free radicals (including pollution), and oxidative stress—drivers of illness and death. Deficiency has been linked to at least 75 illnesses, while higher levels correlate with healthier living.

But there’s a problem: aging depletes Glutathione. Starting around 20, cellular production slows, so an effective solution should aim to raise Glutathione levels in the body.
