Vitamin B1, or thiamine, is one of the B complex vitamins. It is water-soluble, meaning that the body does not store it efficiently and requires a regular intake. Thiamine acts as a coenzyme in several metabolic reactions and plays a critical role in converting food into energy. It also helps support a healthy nervous system and is essential for the proper functioning of the heart, muscles, and brain. (1)

Low vitamin B1 levels can lead to a condition called beriberi, which can manifest in various forms, including dry beriberi affecting the nervous system and wet beriberi affecting the cardiovascular system.
