Vitamin B1 belongs to the group of water-soluble vitamins, therefore it cannot be stored by the body for a long time. Already after 14 days the stored vitamin is up to 50 %. It must therefore be supplied again and again with food and depends also on the individual energy conversion. A folic acid deficiency can also lead to a reduced absorption of thiamine.
Vitamin B1 is heat-sensitive, i.e. up to 30% of this nutrient can be lost during cooking.
Thiamine is important for energy metabolism and the nervous and cardiovascular systems. The brain also depends on a good supply of vitamin B1 to ensure that memory, concentration and learning ability function properly.
Thiamine is responsible for the fact that energy can be obtained from food via carbohydrate, fat and protein metabolism.
Vitamin B1 in its pure form is not processed in the body. Only through interaction with the enzyme thiamine pyrophosphokinase is it converted into thiamine pyrophosphate (TPP). This acts as a coenzyme in the cleavage of carbon dioxide CO2 and thus enables the utilization of glucose.
A good supply of thiamine is just as important for the transmission of stimuli from the nerve to the muscle as for the synthesis of various neurotransmitters in the transmission of information by the nerve cells.
The causes of vitamin B1 deficiency can be varied and range from malnutrition to alcoholism, increased coffee and tea consumption to magnesium deficiency.
The symptoms are manifold, such as fatigue and insomnia as well as irritable mood, loss of appetite and muscle and concentration weakness. The disease beriberi is particularly well known, which includes severe neurological disorders.
Vitamin B1 is found in many plant and animal foods as well as in fatty fish.
