Deuterium is not anything we produce. It comes from food. It’s an isotope of hydrogen. Having excess deuterium actually harms mitochondrial function. We do not want deuterium in our mitochondria. 

Centralized science says Mitochondria’s main function is ATP production. They view the water our mitochondria produce as a byproduct of the ATP creation process. Im saying the water production could be more important than the ATP. 

If you believe all our energy comes from food, then sure, ATP would be very important. But it appears that most of our energy should come from other sources, such as LIGHT. infrared light gives us electrons but we all live inside in a blue lit world so we don’t gather electrons (energy) that way. We have to resort to food from grocery stores if we live inside. 

The deuterium DEPLETED water our mitochondria make forms into a battery which can be charged by the sun (infrared light). (Our windows block most infrared light) how convenient.
