I am very interested in B1 for several reasons. I am a type 2 diabetic and it's been found that about 75% of type 2
diabetics are low in B1. I also stutter and like perhaps almost everyone who stutters I have stuttered all my life.
Way back in 1972 I read that some people who stuttered benefited from extra B1 so I tried some. But back then
the go to form of B1 was thiamine HCL and as luck would have it I had an odd reaction to this one form of B1. It
in a dose related manor made me stutter more, get hungry and get depressed. And back then thiamin hcl was in
almost all vitamin pills and bread products. If I avoided any intake of thiamin hcl about 90% of my stuttering vanished.
When slowly starting in 1980 thiamin HCL was replaced in most vitamins and breads with thiamin mononitrate.
Oh that made life so much easier for me. Then about 4 years ago I read another article on stuttering saying B1
helped about 30% of people who stutter. I started taking about 100mg of thiamin mononitrate several time a day
and most of my stuttering stopped as long as I avoided things that had a high tannin content as tannin flushes a lot
of vitamin b1 from your body. But suppose I know I may need to talk before a large group then I will take 200 mg
of the more expensive sulbutiamine . and for a couple of hrs I am 100% stutter free.
