Free radical is an important factor to cause damages of cell, tissue and organ and lead to aging. Glutathione is most important antioxidant for free radical scavenging in human body, which can delay the aging process. Glutathione is the master antioxidant. If people want to have health and longevity, they must find ways to increase glutathione levels. The high concentration of glutathione indicates good health and longer lives. The low glutathione concentration often prompts the disease and early death.

The body of all organizations, including the liver, kidney, lung, heart, spleen and brain, glutathione levels increase with age and gradually decreased. The results of human studies are the same. Elderly glutathione levels decreased, thus increasing the risks to patients. Older blood glutathione concentration decreased by 20-40% than younger people. Glutathione levels increase in the elderly, regardless of effort, physical, psychological, and social skills are better than peers with glutathione decline. So patients may buy glutathione to improve their health.

Glutathione levels, no significant aging, and generally in good health. Glutathione levels increased 20%, arthritis, hypertension, heart disease and other chronic diseases; reduce the chance of 2/3. Comparison of different ages and health status of glutathione levels. Healthy young people the highest levels of glutathione, followed by the healthy elderly, the sick elderly lowest. This result clearly shows the increase with age and the occurrence of the disease, glutathione-year-old level is decreased. More serious the disease is, lower the levels of glutathione will be.

Scientists conduct experimental research, trying to find elevated levels of glutathione and longevity of the relationship. Glutathione to reduce the biochemical cause of the aging process. Human and mammalian cells to produce glutathione in two ways. Cysteine, glycine and glutamate are assembled into the γ-glutamyl cysteine ​​synthetase and glutathione synthetase, the role of glutathione. Glutathione reductase will restore the oxidized glutathione to the active glutathione.

At present, only breast milk and undenatured protein can provide γ-glutamyl cysteine to the cells making cosmetic raw material glutathione achieve higher levels. There are a dozen countries to produce dozens of brands of whey protein concentrate powder, and its composition is almost the same, but due to protein denaturation, destruction of the mercapto group in cysteine, that is, cysteine -SH residues electron donor, and thus can not improve the glutathione level of the human body; to improve the body's glutathione is not related to the effect of protein nutrition. It relates to its protein activity status.

Glutamate and glycine can be easily obtained from the normal diet, while the cysteine ​​content is rarely in daily diet. Cysteine ​​availability is the limiting factor for the cells to synthesize glutathione. Because of electron donor role of mercapto group in cysteine, glutathione has a biological activity. The free cysteine has a potential toxicity ​​and spontaneous decomposition in the digestive tract and blood. Therefore it is not the ideal cell delivery system.Source:
