A daily supplement of vitamin C is sufficient to enhance and maintain a good level of glutathione in the tissues. It also provides the necessary metabolic precursors for the synthesis of cysteine. The experimental study shows that a daily supplement of 500 mg ascorbic can make glutathione level of the red blood cell increased by about 50%. For those patients with hereditary glutathione deficiency, compared to N-acetyl cysteine ​​(a well-known, effective glutathione accelerator), vitamin C is more effective, more economical to increase glutathione level. Vitamin C helps the body manufacture glutathione and improves the standards of glutathione in body.

Oral S-adenosylmethionine can effectively increase the glutathione levels in red blood cells and liver. Although in many countries people can buy SAM-e, so far in Canada there are no products in markets. Cysteine ​​(the most stringent restrictions on gluthione peptide synthesis, metabolic precursors) is another proven to be effective to promote glutathione levels of nutrients. But the study found that high doses of glutathione can be oxidized. So some people questioned the safety of oral cysteine. However, for N-acetyl cysteine, that is another matter.

The study also found that NAC has a strong anti-oxidation, anti-mutagenic and anti-features. Studies have shown that these tissue glutathione can reach the ideal level of safe, effective method is a daily supplement of 600 milligrams of the NAC. Interestingly, vitamin C and NAC both can effectively increased glutathione level in human bodies which are lack of glutathione. But the study showed that compared with the NAC, vitamin C is more effective and cheaper.

Some other nutrients play an important role in the glutathione metabolic process in way of participating the glutathione peroxidase. Selenium is necessary for glutathione peroxidase activity in the process of resveratrol material, is a secondary factor for glutathione peroxidase. Selenium supplements can significantly promote the activity of glutathione peroxidase.

Selenium supplementation can increase glutathione peroxidase activity in HIV-positive with low abnormally vivo. Similarly, people with multiple sclerosis patients found to contain high doses of selenium, vitamin C and vitamin E supplements can make glutathione peroxidase activity increased by 4 times and enhance the cells anti-oxidative capacity significantly.

Other nutrients which are needed to maintain the ideal function of cellular glutathione peroxidase system includes: riboflavin (vitamin B2) and niacin (vitamin B3). Both of them play an important role in body energy transfer reaction. The energy transfer reaction is part of this important antioxidant homogeneous enzyme system.
