Glutathione is an important antioxidant produced by your body and a master detoxifier of every cell in your body. It prevents cellular damage caused by free radicals and peroxides. Glutathione is an antioxidant that consists of three amino acids -- cysteine, glutamic acid and glycine. Its importance lies in the fact that it exists within the cell wall of almost every single cell in your body and, unlike other anti-oxidants, your body can produce it on its own.
Glutathione is responsible for the following functions, and many more:
- Acts as a “helper molecule” for some important enzymes, such as glutathione peroxidase (which protects the body from oxidative damage);
- Helps with leukotriene production, which is vital for the regulation of inflammatory reactions;
- Assists the liver and gallbladder in detoxifying fats;
- Is involved with methylglyoxal detoxification. Methylglyoxal is a toxin that is produced during metabolism;
- Helps with protein disulfide bond arrangement, a process that is vital for cellular reproduction of proteins in the body;
- Promotes the production and protection of T-cells for immune function;
- Helps to assimilate vital nutrients such as vitamins C and E;
- Contributes to programmed cancer cell death (apoptosis).
One expert explained glutathione as “the place where sulfur and selenium meet up to protect us from cancer.”
Many other studies which have looked specifically at glutathione deficiency in healthy cells have concluded that low levels of GSH within these cells make them more vulnerable to cancer. The proliferation of such studies has determined the current scientific trend in favor of GSH being more of a cancer preventer than a cancer instigator.
