* Detoxification: Glutathione binds to toxins, heavy metals, and environmental pollutants, facilitating their elimination from the body.

* Immune Support: It is essential for the optimal functioning of immune cells.

* Cellular Protection: It protects cells from damage caused by free radicals and oxidative stress.

* DNA Synthesis and Repair: It plays a role in these critical cellular processes.

* Protein Synthesis: It is involved in the creation of new proteins.Glutathione: Uses, Dosage, Side Effects | Vinmec
