Vitamin B1 (Thiamine)
Vitamin B1 or Thiamine is a water-soluble vitamin that is used in nearly every cell in the body. It supports energy levels and a healthy metabolism. Humans cannot produce thiamine, so it must be sourced from the diet or supplements to prevent thiamine deficiency.

Evidence Summary
The body requires thiamine to make adenosine triphosphate (ATP). This is a molecule that transports energy within cells. A thiamine deficiency can impact many different functions of your body, including those of the nervous system, heart and brain. Thiamine deficiency may lead to two major health problems: beriberi and Wernicke-Korsakoff syndrome. Beriberi affects breathing, eye movements, heart function, and alertness. It’s caused by a build-up of pyruvic acid in the bloodstream, which is a side effect of your body not being able to turn food into fuel. Wernicke-Korsakoff syndrome is technically two different disorders. Wernicke’s disease affects the nervous system and causes visual impairments, a lack of muscle coordination, and mental decline. If Wernicke’s disease is left untreated, it can lead to Korsakoff syndrome. Korsakoff syndrome permanently impairs memory functions in the brain. Either disease can be treated with thiamine injections or supplements. This may help with vision and muscular difficulties. Thiamine with other vitamin supplements may reduce the chances of developing cataracts (1) and thiamine may also be helpful for those with diabetes who are at risk for kidney disease (2).
