Studying The Important Nutritional Compound Glutathione

By Tracy Done


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.

The supplies of this substance in the body are found mainly in the liver, where it aids in that organ's detoxifying functions. However, it is also present in the bloodstream, where it appears to help break down oxidized fats. These fats can clog arteries and have other detrimental effects on tissues and organs. In the intestines, glutathione aids in carbohydrate digestion. Throughout the body, it destroys harmful free radicals that accelerate the aging process and contribute to disease 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 demonstrated most clearly in the nervous system. People lacking in glutathione suffer loss of coordination and balance, develop tremors, and exhibit mental disorders. The effects of aging also are accelerated throughout the body.

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.

This nutrient is sold in capsule form. It can also be found in amino acid formulas and liquid proteins. However, since it is not ingested in food but rather produced by the body, some health advisers feel that oral supplementation may not be effective. The studies that will answer this question have not been completed. Many experts advocate instead the supplementation of the three amino acids that are used in the production of the compound.

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.

Because keeping the right balance of nutrients is important, care should be taken when deciding how and when to supplement glutathione. It is best to proceed with the advice of a trained practitioner or by relying on a formula prepared by a manufacturer which bases its products on clinical testing. There is a lot of information on amino acid therapies, and many sources are peer-reviewed to be reliable. Anyone with health issues that indicate a higher need for this compound should invest the time and energy to learn how to use it to best advantage.
