Oxygen must have Alkaline Minerals and Live Carbons to enable the body to fully utilize the Oxygen and maintain a stable supply of Oxygen's Electro-magnetic Energy in our tissues. Not like one supposed Expert on curezone who claims if we just breath in Air we will get plenty of Oxygen and it will Alkalize our body pH, so we don't need to worry about our pH, so he says.
What he doesn't seem to understand is the problem that the Air we breathe contains 21% Oxygen, but it also contains 78% Nitrogen. Nitrogen blocks the Blood Hemoglobin from carrying Oxygen causing our Lymphatic Fluids to become too Acidic, so our Liver and Kidneys must have the Alkaline Mineral of Magnesium to help them remove this excess Nitrogen Waste from our body or our blood cannot carry enough Oxygen to keep us alive. Magnesium has the ability to displace Nitrogen unit for unit!
