B1 possible side effects

[Akita4me]

I started sublingual B1 about 4 weeks ago. 100 mg 1x per week.. I also bought the book. It would be nice to get an idea from fellow users of possible side effects they might be having. One that I think is from B1 is that I get a warm feeling for several days after the dose.Thank you all

we tend to look at side effects as possible signs of overdosing.

Wondering if you know how I can source sublingual vitamin B1 in the UK,

[Akita4me in reply to Kiryn]

Unfortunately no. Best

Only from America. I get mine from here…, but they take weeks to arrive
