  • Thiamine is responsible for breaking down sugars so that vital energy reaches our organs (including the heart and brain) and also our muscles and nervous system.
  • The correct absorption of the different nutrients depends, to a large extent, on maintaining adequate levels of thiamine in the body, in fact it is essential in the development and growth of the human being.
  • The correct conduction of the nerve impulse, the contraction of the muscles, which make it possible from the heartbeat to the movement, depends largely on the presence of thiamine in adequate amounts.
