What is Vitamin B1?

Vitamin B1, also known as Thiamine, is an essential B vitamin that the body cannot produce on its own and must obtain from food or supplements.

The term “vitamin” was first introduced in 1912 by chemist Casimir Funk, who described these essential nutrients as “vital amines.” Vitamin B1 was the first of the B vitamins to be identified.

What does Vitamin B1 do?

Thiamine contributes to:

• Normal energy-yielding metabolism

• Normal functioning of the nervous system

• Normal function of the heart

B vitamins are water-soluble nutrients, meaning they are not stored in significant amounts in the body and are typically obtained regularly from the diet.
