Glutathione is a naturally occurring antioxidant nutrient in the human body, composed of three amino acids: glutamine, cysteine, and glycine. It protects cells from oxidative stress and damage by neutralizing harmful free radicals and reactive oxygen and nitrogen species.

Glutathione exists in three forms: the reduced form, the oxidized form, or S-acetyl-L-glutathione (SAG). When "L-glutathione" is generally referred to, it typically denotes the reduced form of glutathione.

Reduced glutathione (GSH) is the active form. This is the form in which it typically exists within the body. When glutathione engages in neutralizing free radicals, it becomes oxidized itself. This results in the formation of oxidized glutathione (GSSG). Although GSSG is a less active form, it can be regenerated back into GSH.

In the form of S-acetyl-L-glutathione (SAG), an acetyl group has been added to the glutathione molecule. This form is more stable in plasma and can cross cell membranes, thereby facilitating better absorption into the cells.

What are the benefits of orally ingesting glutathione for the body?

· Antioxidant effect, repairing damaged cells and protecting body cells from damage caused by free radicals

· As a detoxifier, it removes toxins from the liver and also protects it from damage

· Relieves fatigue and reduces stress

· Strong immune cells that help regulate inflammation to support the immune system

In addition, glutathione is considered one of the ‘best anti-aging skin care ingredients in the skin’ It acts as a natural antioxidant for the skin to fight free radicals and oxidative damage, plus it helps to eliminate foreign chemicals that the skin is exposed to.

Glutathione's antioxidant characteristics endow it with a broad spectrum of applications, including nutritional supplements, sports nutrition, cosmetics, and skincare products. This has made it highly popular among consumers and is expected to boost the sales of glutathione.
