For two reasons. The first is that the production of glutathione slows down as the body ages, beginning in your twenties. The second is that most people are subjected to a lot of toxins. From the food we eat to the air we breathe, and the products we use, we are constantly bombarded with oxidative stress and environmental stressors. The greater the assault on your body, the greater the chance that you will max out your glutathione stores.

The Liver is the clearinghouse of toxic substances for your body, and is heavily concentrated with glutathione. Glutathione meets up with these toxins and deactivates them by either neutralizing them or flushing them out of the body.

Glutathione is considered the ‘food’ for your immune systems as it is responsible for regulating, producing, and activating the immune cells that help with fighting off bacteria, viruses, and other harmful foreigners in your body.

Glutathione modulates inflammatory markers by reducing the oxidative stress that is increased by exercise, diet, environmental toxins, and stress.

Glutathione assists with cleaning up acids that are produced in your body when you endure strenuous exercise. Glutathione is also significantly concentrated in your lungs and low levels of glutathione can impair functioning.

Glutathione protects the Mitochondria, the powerhouse of your body, from oxidative stress and helps the mitochondria stay healthier so they can produce energy.

As you age, the fatty tissues in your brain oxidize leading to a decline in your information-carrying capacity. Glutathione helps recharge the antioxidants that assist in balancing this oxidative stress.
