One of my long standing problems is that I am cold intolerant. It's not constant, there are some days when it is worse than others. I start to get very cold, and pretty soon after, my sense of wellbeing and ability to think rationally depart me. Feeling cold a lot of the time makes me tense, and when it's really bad it stops me from functioning at all.
Looking around for things that can affect thermogenesis, I came across iron, zinc, copper and thiamine (B1). As this is a group that knows about B12, and thiamine is one of the B vitamins, I wondered if anyone could tell me anything more about thiamine?
