Natural Sources

• Instead of taking a daily supplement, you can get the necessary amount of vitamin B1 through whole-grain cereals, wheat germ, kidney beans, pork, and many vegetables, seeds and nuts. By incorporating some of these foods into your daily diet, you can reach the ideal levels of vitamin B1.
  
  

Consequences

• If a person does not get the adequate amount of vitamin B1, he is prone to beriberi disease. This particular disease causes a person to have difficulty walking and to experience shortness of breath.
