The whole thing boils down to oxygen. Ozone is O3. It’s an excited form of oxygen, and it has many effects on the human body
(1) It increases something called 2,3-DGP, which causes the blood cells to release more oxygen. That dumps oxygen into the tissues.
(2) It improves the rheological properties of blood. That means that the blood cells actually flow better.
(3) It improves mitochondrial oxygen consumption, making more ATP. Essentially making cells function better and regenerating!
Here you have three characteristics of what ozone does to the body, all dealing with oxygen delivery, blood flow, and oxygen uptake and consumption, which means more energy. That’s life.
