It is not that I have misunderstood your writing.
I just don't think most people with metabolism problems have deficiencies in the glycolysis/krebs cycle area.
It feels like ETC is the problem for most because of past PUFA intake and b vitamins can make this worse.
I could be wrong. Just laying my thoughts and my personal experience.
Saturated fat improves oxidative phosphorylation for sure. This has been the most helpful thing for me whenever I can digest enough of it.
Do you know if MB can be obtained in Bulgaria?
I think you can get it from a friend who works in a hospital. MB is one of the most commonly used chemicals for endoscopic procedures. They inject it in tissue that they think is cancerous. So, any hospital with a diagnostic unit should have it but I don't know if it would be pure or mixed with other chemicals used for diagnosis. Also, it should be sold in fish stores for cleaning aquariums, juts as it is in US/Europe. But again, don't know if it would be good for human consumption.
Finally, I have a person who distributes Oxidal in Bulgaria in case the hospital/doctor/fish_store route does not work.
