Thiamine (Vitamin B-1)
Thiamin increases circulation and assists in the production of
hydrochloric acid, blood formation, and carbohydrate metabolism.
Thiamin has a direct correlation to the production of energy, and is
needed for normal muscle tone of vital internal organs. The classic
symptom of a thiamin deficiency is the disease beriberi in
which a person may experience reduced function of the lower
extremities, nerve damage, heart problems, or brain damage. For
example, Korsakoff's psychosis is characterized by the inability to
form new memories, the poorly organized retrieval of old memories,
apathy and emotional blandness. The treatment of these patients with
thiamin often results in significant improvement. In other studies
involving female subjects, marginal thiamin deficiency has been shown
to result in mood swings and irritability. Treatment of these patients
thiamin, again resulted in an improved condition.
