What we are looking at/for is not OTC. The amount of thiamine we are looking at taking would be almost impossible to take via pills, it would be the equivalent of something like tens of thousands of milligrams with all of that filler and capsules to have to contend with on top of the chore of swallowing everything.....several times a day, no less.

Add to this the fact that around 70% of PWP don't have the same (or any- Fox Foundation's study abstract wasn't clear to me on this) of the Prevatella bacteria in their gut which relate to thiamine, and I don't think it's too far of a stretch to say that perhaps taking oral thiamine might not be as beneficial (if at all) as taking it another way where it can bypass the compromised guts in the large majority of PWP.

Plus, I am not aware that we can get injectable thiamin in the US without a script

I know you mean well, ST, and appreciate your skepticism
