Glutathione in Athletic Performance

If you’re a high performing athlete or a sporadic sportsman listen up: glutathione should be in your daily intake no matter what.



Our bodies obtain glutathione from two sources:

  1. What the body manufactures

  2. What we consumer through food and supplements

Glutathione helps to destroy free radicals which are created from normal daily stressors, including exercise.


Citrulline, an amino acid present in glutathione, increases the production of NO - a gas molecule that stimulates the relaxation of blood vessels - which allows a greater flow of blood to reach active muscle tissue (those used when exercising). This means that the athlete gets an influx of oxygen and other nutrients while training which provides them with greater strength and performance.


Athletes require more antioxidants due to the oxidative damage that exercise produces, so it is especially necessary to supplement glutathione. In the long run, athletes in training will improve when they are supplemented with glutathione.

When an athlete is training, they demand a lot more from their bodies. This demand depletes their defenses, and while it benefits the body in many aspects of health, it exposes it to fatigue and oxidation of cells.


The biggest challenge of an athlete when training is to maintain a balance between a good functioning immune system and immune deficiency. Both things compete, requiring the athlete a greater amount of antioxidants in their body to protect themselves from this damage to the immune system with greater responsiveness than a person who does not train their body intensely. For these reasons, It is very clear that the need for glutathione in athletes is essential so that the protection of the antioxidants is able to maintain a defensive power to their immune system.
