This is one that I have not done much with.  I have seen all the claims for it, which sound really impressive including its use for panic disorders, blood sugar regulation, obsessive compulsive disorders, etc.  But I only recently obtained some to add to a treatment for a dog with degenerative myelopathy.  So I bought a kilo of it, but I cannot recall if we ended up using it in his formula or not. We had him on several things that were working great.  He went from not able to get up to being able to run within a week.  When he got a urinary tract infection though it was downhill from there.  The doctor put him on strong antibiotics and that was pretty much it.  He developed really bad diarrhea, and lost all of his strength.  His neuropathy got so bad he chewed through his paw breaking the bone so he had to be put down.

I got the inositol to help with the myelin, but again I cannot recall if we ended up using it.  We were adding new things one at a time to see what he responded best to.

So unfortunately I cannot tell you too much as to effectiveness.  I don't follow sales sites either.  If I am going to work with something I want to see credible information first, then I experiment with things to see if they really live up to the hype.  So maybe I need to dig out the inositol and start playing with it.
