A deficiency in thiamin intake leads to a severely reduced capacity of cells to generate energy as a result of its role in these reactions.

18. Clinical Significances of Thiamin Deficiency
Beriberi, is the result of a diet that is carbohydrate rich and thiamin deficient.
Wernicke-Korsakoff syndrome. This disease is most commonly found in chronic alcoholics due to their poor dietetic lifestyles.
