Studies have shown that those who are old, weak or sick have very low levels of GSH. These are the people who can experience the positive effects of Immunocal® immediately.

The Journal of Applied Physiology has published a study on healthy athletes who often suffers from oxidative stress due to the rigorous training routine they have to go through. In this double-blind clinical study, lymphocyte GSH value was increased by 35.5% and muscular performance increased by 13% for those using Immunocal®. No increase in control subjects who took only casein was observed. This is due to the fact that high GSH resulting from the intake of Immunocal® are able to take care of the free radical production resulting in oxidative stress in such individuals. However, the time for normal healthy individuals to experience the benefits of Immunocal® varies. We encourage these individuals to take note of his energy level prior to taking Immunocal®. Increase in stamina and energy levels will usually be experienced in the first week after consuming Immunocal® due to the increased in GSH. This is usually the first sign on the efficacy of Immunocal®.
