Glutathione

Glutathione is a natural substance made inside your own body's cells. It is a very small building block of protein called a peptide. It acts as the body's main shield against damage and stress. People often look into it to help their bodies fight off harmful toxins, clean out dangerous chemicals, and keep cells healthy and strong as they get older.

Doctors and scientists study glutathione for many different reasons. It works by attaching to bad things in the body and helping to flush them out safely. It also helps fix other healthy vitamins so they can keep working. Many people are interested in it for making skin look lighter and brighter by changing how the skin makes color.

It is also studied for helping the brain, liver, and body recover from stress. There are still many unknowns about how well it works in real people. Taking it by mouth does not work very well because the stomach breaks it down before it can help the body. Doctors sometimes use it through a needle in the vein, but health officials warn that using it this way just to lighten skin is not approved and can be unsafe. It is important to know that it is not a cure-all and should only be used carefully with a doctor's advice.
