I may be wrong but it was my understanding that pantethine was another name for B5, that they are the same thing...
As for whether you should take them, I wouldn't know.
Yes B5 is very important for adrenal recovery, all B's are, I believe, but I wouldn't know how much is best for you.
Are you working with a doctor?
Wow I'm only taking 100 mgs of b5 and I already notice a difference....I'm going to keep working my way up...and yes definately noticing emotional blocks being released...the first one I did was crazy intense....it was like I could feel the energy running thru my entire body....and my face does funny things when I do the codes...it's strange and airy fairy but I know it's the right thing....I can feel it in my soul
