Glutathione, one of the most important antioxidants in human physiology, is found in every cell in the body. To scientists, glutathione is known as the “master antioxidant” because it not only neutralizes free-radicals, it also re-activates other antioxidants like vitamins C and E, providing broad-spectrum protection for the mind and body. It is also involved in numerous biochemical reactions such as protein and DNA synthesis and enzymatic activation, affecting virtually every system in the body, particularly the gastrointestinal, respiratory, nervous and immune systems. Glutathione is a tripeptide molecule made from the amino acids L-glutamic acid, L-cysteine and glycine. Most glutathione is in the human body is manufactured endogenously from its amino acid constituents. Unfortunately, as we grow older, our endogenous glutathione production declines, compromising our antioxidant defenses and leaving us vulnerable to the ravages of free-radicals. Because free-radical damage is in itself a major contributor the aging process, this age-related decrease in glutathione production can lead to a self-perpetuating cycle of mental and physical decline. Fortunately, we can put the brakes on this cycle by augmenting the body’s glutathione production through supplementation.
