Hi. I was told that Creatine is important to take for muscle wasting (massive amounts are needed).
Chronic infection, that then leads to all sorts of leaky gut issues, in addition to ongoing decreased CAC (Crebs) cycle entry (mitochondrial damage) can cause this. So that can mean lyme, co-infections such as Mycoplasma, etc.
The things to get into the CREB cycle from my understanding include: Pyruvate, Ubiquinol (a form of CoQ10), L-Carnitine, and ... shoot I am forgetting the last one...
I am not taking the last one, thus I can't remember..
There is a variety of testing that reportedly will tell you what supplementation would be good for you. Metametrics (urine, stool and blood testing) is often used. Sometimes Naturopaths will do live or dried bloodtesting- you can observe on a screen or microscope how your cells look. Some practitioners will do hair analysis. There is a saliva test that does intracellular elecrolytes that can give you an idea of how your body fares in that area. Hope this helps,
