ways to oxygenate cells? besides exercise

Oxidizing therapies include administering oxygen, ozone, and or chlorine dioxide. I am told liposomal vitamin c can be an oxidant under certain conditions but more often it is referred to as an antioxidant.

Some have talked in the past about Megahydrate. Does that get oxygen to the cells or just water?

I'm looking for something to get oxygen to the cells to aid in exercise intolerance and hopefully raise MSH levels without having to use VIP spray.

Walking - When I had a CFS diagnoses there was a lot of talk in their forums about D-Ribose it increases energy

Sorry my links don't work on american forums but you can figure it out.
There can be a lot of factors that create exercise intolerance. But this may help - its worth looking at the article anyway. I never tried it years ago it was heaps pricier and it is a sugar so I wasnt sure if it would be a good thing for me but I noticed its more reasonable in price these days. I may try it myself I have exercise intolerance. Dr Rawls website says it reduces post-exertion pain and believes it is suitable for lyme sufferers.
Megahydrate, B vitamins, ozone, creatine monohydrate, cordyceps sinensis and D ribose all support ATP production.

Yes I took it for 4 months, but at a low dose. It is just too pricey for my budget. I didn't see any increased energy for me. It bought my pH up a lot. Others on the forum have had better results I think it might work better in healthier bodies. I couldnt come up with a clear idea that I was getting any benefit from it - I might try it later.
