Reduced glutathione, also known as GSH (glutathione-SH), is a naturally occurring antioxidant that is found in almost all living organisms. It is a tripeptide composed of the amino acids glutamate, cysteine, and glycine, and is involved in many cellular processes, including protein synthesis, DNA synthesis and repair, and detoxification of harmful compounds.
In the body, glutathione acts as a free radical scavenger, neutralizing harmful molecules that can damage cells and lead to chronic diseases such as cancer, Alzheimer's disease, and Parkinson's disease. It also plays a crucial role in the immune system by helping to protect immune cells from oxidative damage.
Glutathione is available in supplement form, and is marketed for a variety of health benefits, including improving skin complexion, enhancing athletic performance, and boosting the immune system. However, the efficacy of glutathione supplements is still a subject of debate, and more research is needed to determine their safety and effectiveness.
