Vitamin B1 (thiamine) - What it is, effects and intake

In the following, you will learn everything important about vitamin B1. Among other things, how much you should take, for what vitamin B1 is needed in the body, which foods belong to the vitamin B1 suppliers and what deficiency symptoms can occur.

What is vitamin B1 (thiamine)?

Vitamin B1, also known as thiamine, is a water-soluble vitamin that is particularly important for energy metabolism. More specifically, the body needs it for energy production from carbohydrates. It is also involved in amino acid metabolism and is essential for the nervous system.

What is vitamin B1 good for?

Vitamin B1 is involved in various processes in the body. Strong nerves, a clear head and more balance are just a few benefits of an adequate B1 supply. The B vitamin is particularly important for the central nervous system. It plays a decisive role in regeneration after illness or trauma. Together with vitamin B6, it is used to treat nervous system diseases. Together, both vitamins are said to have a particularly good effect. They influence various metabolic reactions, can repair damaged nerve fibres, and have a pain-relieving effect. 

According to studies, B1 has even been shown to have a soothing effect on PMS symptoms.
