Vitamin B1

Vitamin B1, also known as thiamine or aneurin, is a water-soluble, oxidation-sensitive and thermolabile B-complex vitamin. It is mainly involved in metabolism and ensures that the food taken in by our body is converted into vital energy. In addition, vitamin B1 guarantees the functioning of important activities between the nerves and the brain. A particularly high concentration can be found in the brain, liver, kidneys, skeletal muscles and cardiac muscles.

  • Extracts energy from food
  • Forms new cells and muscles

Natural protection against mosquito bites

Vitamin B1 is effective against mosquito bites

A study demonstrated that the skin of subjects sufficiently supplied with vitamin B1, developed an odor which cannot be perceived by human beings but keeps mosquitos at a distance. Thus, vitamin B1 can be regarded as a natural mosquito repellent. Vitamin B1 intake is therefore a good protection for those, who travel to countries where Malaria is endemic.

Natural sources

It is basically possible for an adult person to cover the daily needed dose for vitamin B1 which amounts to 1-1.5 mg, since there is a wide range of natural food which ensures a balanced supply with thiamine. Pork, liver, various sea foods as well as potatoes, in particular, are rich in vitamin B1. Likewise many types of grain and pulses are also suitable for covering the daily need. However, in this regard it is crucial not to cook the food with high heat to prevent it from losing the B1-vitamin, since about 30% of the thiamine is lost during the preparation and the cooking process.

Production and storage

Vitamin B1 should be regularly so that the body can not store it

The human body in itself is not capable of producing thiamine, which is needed for many metabolic processes. Similarly, storage is only possible to a limited degree. On the one hand, our body can store an amount of up to 30 mg. For this reason it stores small amounts of this vitamin in different organs as well as in the brain. However, due to daily consumption, the body runs out of its supply after one month at the latest. To prevent dietary deficiencies, it is urgently required to supply our body with this vitamin over and over again, hence preventing a deficiency in the body. Our body, however, cannot use more than about 6 mg per day which is why even an over-supplementation would be useless. With a daily intake of 6 mg or more of vitamin B1, the body is only able to absorb between about 5 to 10% of the supplied amount. Thus, the body’s own vitamin level can only be increased if vitamin B1 is taken for a longer period.

Deficiency symptoms

Beriberi is a main indicator that the body is not being supplied enough vitamin B1. Symptoms of the disease include weariness, heart disorders and muscle problems. In addition, undersupply can result to brain damage. Not less dangerous is a decrease of the pH-value in the blood. If the blood is acidified this can lead to heart failure. Moreover, mental limitations would be identifiable by states of lethargy, lower motivation as well as depression. Malnutrition or alcoholism is increasingly contributing to a vitamin B1-deficiency, a symptom which can be seen more and more in developed countries. Brittle nails and hair can also be the result of a vitamin B1-deficiency. Therefore it is indispensable to get vitamin B1 from your diet daily but also to take a sound food supplement in order to keep your body healthy.
