Thiamin (Vitamin B1 or thiamine) is an essential nutrient required by the body for maintaining cellular function and consequently a wide array of organ functions. Deficiency of thiamin leads to wholesale degeneration of the body, particularly the nervous and circulatory systems, and eventually death.

Further, deficiency of thiamine can lead to the development of beriberi and/or Wernicke-Korsakoff syndrome. Symptoms of both include severe fatigue, and degeneration of cardiovascular, nervous, muscular, and gastrointestinal systems.

Over-consumption of thiamin is unknown and studies show that amounts taken well in excess of the daily value (DV) can actually enhance brain functioning.

Foods high in thiamin include pork, fish, seeds, nuts, beans, green peas, tofu, brown rice, squash, asparagus, and seafood. The current daily value (DV) for vitamin B1 is 1.2mg.
