Hi Dbkita,
I got clobbered on the krebs cycle. I had lactic aicid burn in my mucles for 17 years. That told me something was very wrong. I couldn't find a single doctor willing to look at that or any of the specifics. They all preferred to call me names for having "yuppie flu", conversion disorder, etc. The only yuppies we have around here are the Young Urban Peregrines flying the canyons of the city eating pigeons.
What I did learn is that chasing individual results rather than the root cause didn't work well. I had hundreds of apparantly unrelated symtpoms and the docs were 100% puzzled. Finding what the MOST LIMITING FACTOR was turned out to be very important. When I said "everything worked better after MeCbl", and I could also have said that about AdoCbl if taken first, and you have noticed it, you have identified one of your most limiting factors. Things happen fast when you identify that. Then while maintaining that, the next item in each individual's line becomes the most limiting factor.
For the methylation line it looks something like MeCbl, L-methylfolate, Choline, SAM-e, B6, TMG; and some others
For the Krebs Cycle in the mitochondria, AdoCbl, L-carnitine fumarate, Alpha Lipoic Acid, Vit C, L-methylfolate, D-ribose and some others.
However, every vitamin is essential and any of them can become most limiting factors as can various minerals. A difference with potassium, it brings things to a halt via death rather than a breakdown in healing. Also, kidney damage, adrenal hormones, insulin and many other things get mixed up with potassium regulation. I was fortunate to have simple uncomplicate hypothyroid that responded to standard therapies but that can be a real problem too.
