Vitamin B1

Vitamin B1 – Water-soluble vitamin for energy, nerves, and heart

Vitamin B1, also known as thiamine, is a water-soluble B vitamin that is essential for energy production and for the proper functioning of the heart muscle, nervous system, and brain. The body cannot make vitamin B1 on its own, so it must be obtained daily through food or supplements. In dietary supplements, vitamin B1 is mainly used to support normal energy metabolism, mental performance, and nervous system function as part of a balanced lifestyle.

Characteristics, Origin, and Composition

Vitamin B1 naturally occurs in bread and grain products, potatoes, vegetables, meat and processed meats, milk and dairy products, and according to Apotheek.nl also in nuts and yeast . The natural form in foods is thiamine or thiamine diphosphate, while supplements commonly contain thiamine hydrochloride or thiamine mononitrate . One of vitamin B1’s central roles is converting carbohydrates into energy, which makes it particularly important for tissues with high energy demands such as the brain, nerves, and heart.

Use in Dietary Supplements

Vitamin B1 is used in supplements and sometimes as a medicine to prevent or correct deficiency . It is often included in energy-support or B-complex formulas because it helps turn nutrients into usable energy and has a positive influence on concentration, memory, and mood. When deficiency occurs, symptoms can include low mood, concentration problems, memory issues, weak muscles, numbness in the arms or legs, nausea, poor appetite, and heart-related complaints.

Everyday Use and Well-Being

Vitamin B1 deficiency is seen most often in risk groups such as people with heavy alcohol use, very restrictive diets, certain gastrointestinal diseases, or severe nausea and vomiting during pregnancy. Severe deficiency can lead to beriberi or Wernicke-Korsakoff syndrome. Excess thiamine is normally excreted in the urine, and no adverse health effects from high intake are known . Under normal use, vitamin B1 generally does not cause side effects .
