When your lungs’ natural cleaning and repair system is damaged, germs, dirt and chemicals from cigarette smoke stay inside your lungs. This puts you at risk for chronic cough, chest infections, lung cancer and COPD. Besides not smoking, your lungs would probably request that you learn more about a protein that is crucial in keeping it healthy. That protein is called glutathione or GSH for short.

Glutathione is a protein that is produced in every one of the trillions of cells in your body. It’s so crucial that you literally could not survive without. In its absence, your body would fall victim to illnesses that a healthy person would just sneeze away.
