Researchers have discovered that a compound produced by the liver has many functions in the human body. Glutathione, once thought to be an amino acid, is actually a synthesis of three of these vital building blocks of protein. This valuable substance is both a product of metabolic processes and an active agent in them, as it works as a purifying antioxidant.

This compound is involved in many metabolic processes in our bodies. Research has shown that it is present mainly in the liver but is also found in the lungs, the bloodstream, and the intestines. It is beneficial for metabolism and is believed to protect white and red blood cells, and helps break down oxidized fats which act as harmful free radicals. Free radicals are believed to accelerate the effects of aging and to contribute to many illnesses and chronic conditions.

Although all of us need this important nutrient, those who smoke or drink excessive amounts of alcohol will benefit the most. Glutathione appears to protect the lungs from harmful chemicals in tobacco smoke. It also seems to protect liver cells from damage by alcohol.

A deficiency of this substance is quickly revealed by the nervous system. People with a deficiency suffer from tremors, mental disorders, a loss of balance, and lack of coordination. Internal damage is found in many vital organs when the supply of the essential compound is inadequate.

Levels of this essential substance decrease with age, either because the body produces less of it or because more of it is used in the metabolic process. Researchers have called glutathione the 'master antioxidant', even more valuable than Vitamin C. Studies continue to show how effective it is in maintaining health throughout life.

It comes as a single substance in capsules, and is also available in combination formulas. However, since the compound is not found in food but is produced internally by our own bodies, the value of oral supplements is questioned by some health experts. It may be that supplementation of the three amino acids that are used to produce Glutathione is a better way to get an adequate supply.

Cysteine, glutamic acid, and glycine are the components of the 'master antioxidant'. Although these true amino acids are found in food, they are affected by the heat of cooking and by processing. Supplementing these building blocks might be the best way to insure your body has what it needs to maintain and restore health.

Glutathione is necessary for life and health. However, it should not be taken without the advice of a trained practitioner or without comprehensive study of the role of amino acids in our bodies. There are special forms of these important nutrients that have been clinically tested and found to be superior. There is a lot of information on this subject; just be sure it comes from a reputable source.
