Folks, this is very interesting.
Pantothenic acid is vitamin B5.
Pantethine is Pantethine (bis-pantethine or co-enzyme pantethine) is a dimeric form of pantetheine, which is produced from pantothenic acid (vitamin B5) by the addition of cysteamine. (Wikipedia).
I got onto this lurking about chronic fatigue message boards.
I'm already taking B5 (though this doctor recommends a higher than my high dose) and he says to take it with Pantethine, which I'll now have to source. I'll give it a go.
My hormone levels are low, but the doctor says I don't need supplementation yet. I suspect the adrenal glands are responsible for my crushing fatigue. Though, reading the tales of woe on the CFS message boards I got it easy.
I'll post more later.
Be well, comrades. Be well.
