B vitamins B: A complex guide for functions, interactions and assimilation
B1 (Tiamin): the key to the energy exchange and the nervous system
Thiamine, or vitamin B1, plays a vital role in the metabolism of carbohydrates, fats and proteins, turning them into energy necessary for cellular functions. It is a cooferment for several key enzymes involved in the Crebs cycle and the pentosophosphate path, the main ways of energy production in the body. In addition, thiamine is necessary for the normal functioning of the nervous system, since it is involved in the synthesis of neurotransmitters, such as acetylcholine, and maintaining the myelin shell that protects the nerve fibers.
