Vitamin b1

Does anyone know what to much B1 can do to you?

Excess of vitamin B1 is not stored but after the body uses the needed amount of vitamin b1 the excess is excreted through the urine.
Therefore excess of vitamin b1 is uncommon, even though if there is excess of vitamin B1 it may cause lack of other vitamins, therefore needs to be taken with other vitamins B.
