When too much vitamin b1 is consumed how does the body treat the excess?

When excess vitamin B1 (thiamine) is consumed, the body typically excretes the surplus through urine, as it is a water-soluble vitamin. Since the body does not store large amounts of thiamine, any excess is usually eliminated rather than stored. This mechanism helps to maintain appropriate levels of the vitamin needed for metabolic functions without leading to toxicity. Thus, high intakes of thiamine are generally considered safe.
