Thought I'd repost Vinero's excellent post from another thread.

Vinero said:It seems that a thiamine deficiency, also known as vitamin B1, can have some undesirable consequences such as:
-Increased histamine levels: http://link.springer.com/article/10.1007%2FBF01997372
-Low body temperature: http://www.ncbi.nlm.nih.gov/pubmed/2090843
Haidut already posted studies about how thiamine can cure Crohn's/IBS, MS fatigue, and Alzheimers in massive doses ranging from 500mg-1500mg every 4 hours. The sufferers in the studies weren't deficient in thiamine according to bloodtests, yet benefited from supplementation.
The standards for adequate thiamine are simply too low; or the body has trouble getting thiamine into the cells despite normal blood levels.
So, if your still having low temperatures, stomach problems, and excess histamine despite doing everything right, you might have a mild thiamine deficiency going on. Especially if you are eating a lot of white sugar, caffeine, aspirin, etc which stimulate metabolism deepening the thiamine deficiency.
