Glutathione is a tripeptide containing γ-amide bond and sulfhydryl group, composed of glutamic acid, cysteine and glycine, present in almost every cell of the body.
Glutathione can help maintain normal immune system function, and has antioxidant and integrated detoxification effects. The sulfhydryl group on cysteine is its active group (so it is often abbreviated as G-SH), which is easy to combine with certain drugs and toxins, so that it has an integrated detoxification effect. Glutathione can not only be used in medicine, but also can be used as the base material of functional food, which is widely used in functional food such as delaying aging, enhancing immunity and anti-tumor.
the Glutathione Reduced Powder has two forms, reduced (G-SH) and oxidized (G-S-S-G), and reduced glutathione accounts for the vast majority under physiological conditions. Glutathione reductase can catalyze the interconversion between the two types, and the coenzyme of this enzyme can also provide NADPH for the metabolism of pentose phosphate bypass.
The name of glutathione may be unfamiliar to many people, but in fact this ingredient was discovered by Nobel Prize winner Hopkins as early as the 1880s. It is a tripeptide composed of glutamic acid, cysteine and glycine containing γ-amide bonds and sulfhydryl groups. It is known as "super antioxidant", "life cell guard" and so on. Glutathione is widely present in various mammals, and it exists in almost every cell in the human body. Therefore, the biggest difference between it and niacinamide, grape seed and other ingredients is that it is a self-contained ingredient in the human body. Therefore,
it is easier to absorb and utilize. Because of its important functions of anti-oxidation, detoxification and supporting the operation of the immune system, it was mainly used for medical purposes in the early stage, and then applied to the field of skin care, mainly for whitening and nourishing skin, anti-oxidation and anti-aging, and lightening spots.
Compared with glutathione, other Internet celebrity whitening ingredients have their own shortcomings. For example, the principle of action of nicotinamide is to block the transport of melanin to the stratum corneum of the skin after formation, and cannot prevent the formation of melanin. Arbutin is a derivative of hydroquinone, and its concentration must be strictly controlled, otherwise it may cause cancer, so it can only be used externally and cannot be taken orally. Resveratrol, grape seeds, etc. are plant extracts, and the combination and absorption effect with the human body is not ideal, and the utilization rate in the human body is not high. Among them, the bioavailability of resveratrol metabolites in the small intestine and liver About 1%.
Glutathione, as an endogenous substance in the human body, not only has high safety, but also has a high rate of oral absorption and utilization. It can act on the two key links in the formation mechanism of melanin in human skin, breaking black from the source layer by layer. Ultraviolet rays stimulate the production of free radicals, and glutathione combines with free radicals through active sulfhydryl groups to scavenge oxidative free radicals and reduce the accumulation of melanin caused by increased ROS. At the same time, glutathione competitively binds to the copper ions of tyrosinase, which can lead to the inactivation of the enzyme, thereby inhibiting its activity. Glutathione can also play a third role. It reacts with dopaquinone, a precursor of melanin, to finally generate pheomelanin instead of darker melanin, which helps to brighten and whiten the complexion.
As a hepatoprotective drug, reduced glutathione is widely used in infectious diseases, hepatology and hepatobiliary surgery. Its main functions are:
First, it is mainly suitable for various liver damage and liver diseases, especially for liver damage caused by hepatitis or liver function damage caused by alcoholic hepatitis and drug-induced hepatitis. Generally, it is used in combination with drugs used to treat diseases, and has a protective effect on liver function damage caused by drugs.
Second, it can be used as an auxiliary treatment for heavy metal and organophosphate poisoning.
Third, as a prevention and treatment of radiation damage and blood system diseases, it also has an auxiliary therapeutic effect.
Fourth, recent studies have found that it can be used for facial pigmentation, sweat spots and other skin diseases. For elderly cataract patients, its eye drops can also be used to treat eye diseases.
hint:
Lack of sleep can greatly reduce glutathione levels. Make sure you follow a good sleep pattern.
Stress depletes glutathione. To increase glutathione production, it is important to remain stress-free. Yoga is one of the best ways to fight depression and deal with mood swings.
