1. Glutathione Overview
Where to buy Glutathione Powder with lowering Glutathione price and high quality? Where to find good information of Wholesale Glutathione and Purchase Glutathione for sales? As the professional Glutathione manufacturer, BFSTAR is your best choice.
Glutathione (GSH), also named Reduced Glutathione, is a tripeptide composed of glutamate, cysteine, and glycine. It can be found in almost every cell of human body. Nowadays, the industrial production of Glutathione is mainly obtained by enzymatic synthesis. In the method, Glutathione has a high purity and good water-solubility. As an active tripeptide with important physiological functions, Glutathione is the most important non-protein sulfhydryl compound in organisms. It has biological activities such as detoxification, anti-oxidation, free radical scavenging, skin-whitening and spot-fading. Therefore, it is widely used in cosmetics, medicine, health care products and other industries. It can be soluble in water greatly and easy to be added into all kinds of skin-whitening cosmetics. BFSTAR Glutathione is divided into cosmetics grade and medical grade.

2. Glutathione Source
There are four main methods of preparing Glutathione: enzymatic synthesis, solvent extraction, chemical synthesis and fermentation. BFSTAR produces Glutathione by enzymatic synthesis. And the product is of high purity and less pollution to environment. It has a good performance-price ratio.
| Method | Raw material | Operation | Purity | Pollution |
| Enzymatic synthesis | Use L-glutamic acid, L-cysteine and glycine as substrate, and use the natural glutathione synthetase of organisms, then add a little ATP/ADP to synthesize Glutathione | Fast reaction speed, high sensitivity, clear process, but high cost. | High | Low |
| Solvent extraction | Use wheat germ and yeast as raw materials, and then separate and purify to produce Glutathione. | Backward technology, small production scale, low output, low cost. | Higher than that of enzymatic synthesis. | Low |
| Chemical synthesis | Use glutamic acid, cysteine and glycine as raw materials to synthesize Glutathione | Many reaction steps, long reaction time, complex operation and high cost. | Low | Severe |
| Fermentation | Use cheap carbohydrates as raw materials, then convert the materials into glutathione by the metabolism of substances in specific microorganisms | Mild reaction conditions, fast production speed, low cost. | Not high | Low |
3. Reduced Glutathione VS Glutathione Disulfide
| Reduced Glutathione (GSH) | Glutathione Disulfide (GSSG) | |
| State | Active state | Inactive state |
| Percentage of glutathione | More than 95% | 1% or so |
| Function | Free radical scavenging, anti-aging, skin-whitening | / |
| Application | Whitening and antioxidant cosmetics | / |
| Relation | Reduced Glutathione can convert into GSSG. GSSG’s physiological activity is very low and has little effect, because it accounts for a small proportion. So Glutathione is usually called Reduced Glutathione, and it plays a main role. | |

6. Glutathione Benefits
- Whiten skin and remove freckle
Glutathione can chelate internal and external toxins such as heavy metals. It can prevent skin pigmentation. Also it can inhibit the formation of new melanin and reduce its oxidation. Glutathione alleviates skin problems such as chloasma. It has a great function of lightening skin and removing freckles. Meanwhile, Glutathione is small molecular peptide. So it can easily penetrate cell membrane and be absorbed by the skin, when applied externally. It is an effective cosmetic ingredient for whitening skin
- Anti-oxidation
Glutathione’s structure contains a lively thiol group-SH. So it is easily oxidized and dehydrogenated. The free radicals can be reduced directly into acidic substances by combining the thiol group with free radicals in the body. Thereby it accelerates the elimination of the free radicals; and fight against free radical damage to the skin. At the same time, Glutathione is a kind of radiation protective agent. It can enable radiation to produce highly active free radicals in living organisms through direct and indirect action. And then Glutathione can clear away these free radicals to achieve its anti-oxidant effect.
- Isolate PM2.5
Glutathione can isolate the damage of PM2.5 to the skin, when acting on the skin surface.
