Glutathione is the body’s main antioxidant and antidote, is one of the commonly used cosmetic raw materials healthy foods. Glutathione levels can not rely on increased oral intake dose to improve clinical effects, this is because it is generated by the early form of glycine, glutamate and cysteine amino acids in the cell.
Therefore, healthy food is the premise to increase glutathione, or through other means to promote its production. And secretion of intracellular glutathione is also affected by the impact of the sulfur-containing amino acid and homocysteine levels.
Cysteine as a free amino acid may be existed toxicity, it is natural metabolites formed in the gastrointestinal tract and the plasma decomposition process. But cystine is relatively more stable than cysteine. Intake healthy food rich in sulfur amino acids help to raise glutathione levels. Here are some sources of health food and nutritional supplements, which can naturally increase the levels of glutathione in the blood. It derived from amino acids, and as a pre-form of glutathione. Once the N-acetyl-L-cysteine into the body can be rapidly metabolized and converted into glutathione. Scientific research and clinical trials have proved that the healthy food containing it can increase the production of the intracellular glutathione. It commonly used in the treatment of lung diseases, such as fibrosis cysts, bronchitis and asthma.
Silymarin, milk thistle is a powerful antioxidant, support and prevent liver glutathione depletion. Silymarin is the active compound of milk thistle, which is a natural liver detoxification agent, can protect the liver from many industrial toxins such as carbon tetrachloride damage.
Alpha lipoic acid is naturally acquired in human cells, and as a by-product of energy release, alpha lipoic acid increase intracellular glutathione levels, is a natural antioxidant with free radical scavenging ability. It has the regenerative capacity of the antioxidant, such as vitamin C and E, and to improve their effectiveness. Alpha lipoic acid can also help improve the absorption of glucose, and to prevent cell damage associated with diabetic complications caused. In addition, it has a certain degree of protection of the efficacy of the brain.
According to glutathione supplier, asparagus is a main source of glutathione. Healthy foods such as cabbage, avocado and spinach also thought that can increase the levels of glutathione. Raw eggs, garlic and fresh unprocessed meats also contain high concentrations of sulfur-containing amino acids, and helps to maintain optimal levels of glutathione.
Whey protein contains sulfur amino acids. However, heating or pasteurization destroyed milk disulfide bonds, make these proteins lost the biological activity. Whey protein is a non-heated product, therefore maintain the biological activity of cystine and other amino acids. Much of the scientific research and clinical trials, it has been proven that can optimize glutathione levels.
Curcumin has the role of treating brain cells, astrocytes. Have been found that put Indian curry spices with it can increase the glutathione S – transferase and protect neurons contact with oxidative stress. Platy codon root, can greatly reduce the oxidative damage to liver cells and reduce cell death and lipid peroxidation. Selenium supplements have become a popular health food, because some studies have found that they are likely to reduce the risk of certain types of cancer, and have the function of improving the immune system and thyroid. However, too much selenium will cause some side effects, including gastrointestinal upset, brittle nails, hair loss and mild nerve damage and so on.
