Functions, needs of vitamin B1 (thiamine) and foods richer in this vitamin, an essential nutrient for the nervous system.

Vitamin B1 (also known as aneurin or thiamine), is a clearly essential vitamin for the normal metabolism of carbohydrates or carbohydrates.

Among other aspects, it is necessary for the formation of an enzyme that allows the degradation and assimilation of carbohydrates, playing a very important role in the  functioning of the nervous system.

Precisely because of these issues, its deficiency is certainly revealed through very serious problems of a nervous, mental and even cardiovascular nature. It must generally be found in sufficient quantities in our diet, ideally on a daily basis.

This is of vital importance because unlike other vitamins (such as vitamin A, which we discussed a few days ago), the body is not able to accumulate reserves of vitamin B1.

What are the functions of vitamin B1 or thiamine?

  • It is involved in the absorption of glucose by the nervous system.
  • Helps with good eye health.
  • Indispensable for the correct health of the nervous system.
  • It intervenes in the transformation of food into energy.
