Thiamine, thiamin or vitamin B1 (/ËÎ¸aÉª.ÉmÉ¨n/ THY-É-min), named as the thio-vitamine (sulfur-containing vitamin) is a vitamin of the B complex. First named aneurin for the detrimental neurological effects if not present in the diet, it was eventually assigned the generic descriptor name vitamin B 1.
Thiamine is a water soluble B complex vitamin. Thiamin is involved in many body functions including the nervous system, muscle function, metabolism, digestion and other biochemical processes. Because thiamin is water soluble and very little is stored in the body, depletion can occur rapidly.
