Purification Chamber needs only 2.0 Watt to trigger electrons- electron holes movement forming OH radicals and super Oxygen substances adhered on surface of photocatalyst which is the only technology killing viruses. (devicenext.com)

The consumption of whole fruits and vegetables appears to be superior to an ascorbic acid supplement for antioxidant effectiveness. (wvu.edu)

It is also very helpful in cytotoxic conditions in the brain because it promotes cellular oxygen consumption and reduces anaerobic glycolysis. (ivleaguelife.com)
Studies show dramatic increases of cellular oxygen consumption and glucose uptake when using Methylene Blue. (compasslaboratory.com)

However, when free radicals overwhelm the capacity of antioxidant system in the erythrocyte, oxidative damages may occur endangering the integrity of the erythrocytes [3,4]. (scirp.org)
