hi monica, I'm on an iphone and it is hard to type so I will be brief. Vitamin b5 is not inositol; it is not really a b vitamin but is grouped with them for soMe reason. Chiro inositol is a specific isomer of it that is being investigated for type 2 diabetes and pcos. You can find more info on pcos web forums that you can google. Myo inositol is the common type in supplements and is less potent but does woRk In higher doses. If you found a commercial source for chiro send me a pm since I only found a few sources a year or so ago. I will be back in a week or so and will have better answers then; this iPhone is hard to type on and my son is doing it for me.
