Vitamin B1 plays an important role in the breakdown of carbohydrates such as sugar and starch. For example, the organism needs around 0.2 mg of vitamin B1 to break down 100 g of chocolate. Vitamin B1 is also involved in the function of nerves and muscles. A lack of vitamin B1 thus leads to disorders in the utilization of carbohydrates, to nerve diseases and muscle weakness. Benerva is used to supplement an insufficient vitamin B1 intake with food and to cover an increased requirement.
Insufficient intake: Vitamin B1 is mainly found in the outer shell of grains and in yeast. A vitamin B1 deficiency can occur if you mainly eat finely ground grain flour instead of whole flour. Use in the event of a vitamin B1 deficiency requires the recommendation of a doctor or pharmacist.
Increased need: The need is increased in the case of insufficient absorption by the body as a result of gastrointestinal diseases, alcohol abuse, heavy physical work, as well as during pregnancy and lactation.

Benerva is also well tolerated in very high doses taken over a long period of time. Nevertheless, stick to the dosage instructions described below. Higher doses are useless as they are quickly excreted in the urine and sweat.
Medicines that neutralize gastric acid (antacids) inhibit the absorption of vitamin B1 in the intestine. It is also known that certain tuberculosis and cancer preparations counteract vitamin B1.

Allergic reactions such as itching, rash, nettle rash and skin swelling and asthma, but also disorders of the gastrointestinal tract such as nausea, vomiting , diarrhea or pain occur.
