Well, yeah, I'm still kind of 'stuck' with ET.
Don't like the fructose, small dose tablets, etc.
I've been wondering for some time if the amount of mannitol in these B12 supps. has anything to do with its efficacy.
Mannitol has been used to help drugs cross the BBB.
Most of the other subs. have it too, but, how much ?
I've been able to reduce the dosage, but with all the oral problems I've been having, now I don't keep it in the mouth so long, and I rinse afterwards.
