"the failure of pyridoxal kinase in the liver to activate B6"

What does this comment mean? B6 is an issue I am dealing with and probably the reason I have neuropathy. I found your comment interesting but don't fully understand...

I have been told to take P-5-P, but no one including the healthfood stores in my area or my doctors have heard of it. As far as they are concerned it is just "B6".
