The influence of oxygenated water on the immune status, liver enzymes, and the generation of oxygen radicals: a prospective, randomised, blinded clinical study

Conclusion: Long-term consumption of oxygenated water has no apparent harmful effect on the liver, blood and the immune system. Moreover it leads to a transient moderate increase of oxygen radicals in the blood. An interesting observation is the increase of the Th1/Th2-ratio in the Verum group, whereas in both groups T-cell activation after mitogen stimulation, the soluble IL-2 receptor, the CD4+ and the naïve CD4+CD45RA+ cells increased.
