Glutathione is a naturally occurring antioxidant that plays a crucial role in many physiological processes in the body. Some of the key functions of glutathione include:

1. Detoxification: Glutathione helps the liver to remove harmful toxins and chemicals from the body.

2. Immune support: Glutathione helps to support the immune system by promoting the production of white blood cells.

3. Anti-aging: Glutathione helps to reduce oxidative stress and inflammation, both of which are associated with aging.

4. Skin health: Glutathione is often used as a skin lightening agent to reduce the appearance of dark spots and blemishes.

5. Athletic performance: Glutathione may help to improve athletic performance by reducing muscle damage and fatigue.

6. Cancer prevention: Glutathione has been shown to have anti-cancer properties by helping to prevent DNA damage and reducing oxidative stress.

It's important to note that it is very hard to eat enough fruits, vegetables, and lean protein sources to increase your glutathione levels and as you age supplements are needed.

While glutathione is naturally produced by the body, certain factors such as stress, poor diet, and environmental toxins can further deplete its levels. For those seeking to enhance their glutathione levels, many individuals turn to supplements like the "best liposomal glutathione" to support their overall well-being.
