Glutathione (GSH) is a tripeptide compound containing γ-amide bonds and sulfhydryl groups. It is formed by the condensation of three amino acids: cysteine, glutamic acid and glycine through peptide bonds. There are two main types of glutathione, namely reduced glutathione (GSH) and oxidized glutathione (GSSG).


The main active component of glutathione is reduced glutathione. Therefore, glutathione usually refers to reduced glutathione.


Glutathione exists in all animal and plant cells, and is abundant in the kidneys, livers, red blood cells and wheat germ of animals.


Glutathione plays a direct or indirect role in most life activities, so glutathione is widely used in many fields.


In human cells, glutathione is a naturally synthesized tripeptide and a non-enzymatic antioxidant, and this antioxidant is also synthesized by cells. Glutathione can not only maintain the body's redox balance and participate in the antioxidant response of cells, but also plays an important role in regulating cell proliferation, the body's immune response, and acting as a neuromodulator and neurotransmitter in the nervous system.


Reduced glutathione is not easy to store under high water activity. Only when the water activity is controlled below 0.3 can reduced glutathione be stored stably for a long time.


Studies have shown that reduced glutathione is easily oxidized, but if reduced glutathione is placed in an aqueous solution containing vitamin C (pH value 3.3), because vitamin C has strong reducing properties, the reduced glutathione in the solution will Thione will not be oxidized, but its decomposition rate will be accelerated; and the oxidized glutathione itself will not be transformed and has good stability.


Products containing glutathione and vitamin C have better stability.
