You should be able to get all the thiamin you need from your daily diet.
Thiamin can't be stored in the body, so you need it in your diet every day.
What happens if I take too much thiamin?
There's not enough evidence to know what the effects might be of taking high doses of thiamin supplements each day.
What does the Department of Health advise?
