Want to improve your immune system? University of Alberta researchers found that male subjects involved in strenuous aerobic activity suffered from significantly reduced glutathione levels that could impact on such things as the nervous, gastrointestinal, and immune systems. However, they also discovered that by supplementing with whey protein, the subjects experienced a significantly lesser reduction in glutathione levels. If you like extended cardio sessions, but don’t want to risk a reduction of glutathione levels, combat those effects with whey.
