What is vitamin B-1 used for in the body?

Vitamin B-1, also known as thiamine, is the first ever B vitamin to be discovered by scientists.  It is essential for the function of all tissues in the body, including the brain, heart, muscles, liver and nervous system. This is because it provides necessary energy for cell growth, development and function, by converting carbohydrates, fats and proteins into adenosine triphosphate (ATP), a form of energy that fuels the body. 

Because vitamin B-1 is involved in so many cell functions and the breakdown of nutrients for energy, a deficiency can lead to various problems in the brain, heart and other organs that require a constant supply of energy. Deficiency can also lead to nerve damage and problems with the nervous system. Vitamin B-1 supplements can help prevent deficiency and provide a number of health benefits to the body.

Energy production

Carbohydrates provide energy for the body, especially the brain and nervous system. Vitamin B-1 helps the body's cells change carbohydrates into energy in the form of ATP,  which can be used as fuel for numerous bodily processes and reactions, particularly in the brain and nervous system. 


Vitamin B-1 is important for good eye health. Evidence suggests that people who have plenty of B-1 in their diet are less likely to develop cataracts, and that vitamin B-1 supplements may help protect the eye lens and prevent the development of cataracts

Heart disease

Vitamin B-1 is key to the production of acetylcholine, an important neurotransmitter that helps the body pass messages between its nerves and muscles, and ensures proper cardiac function. Vitamin B-1 deficiency may result in irregular cardiac function,, which can lead to poor cardiac health.

Brain function

Vitamin B-1 plays an important role in brain function, memory and concentration. B-1 supplements have been shown to improve cognitive function in people with Alzhiemer’s and are also believed to help slow progression of the disease. Lack of vitamin B-1 has also been linked to low mood, and taking supplements alongside antidepressants may help improve symptoms of depression

Diabetes management

Research suggests that vitamin B-1 supplements may help manage high blood sugar and insulin levels, and reduce high blood pressure and heart complications, in people with diabetes. 

Vitamin B-1 is essential for providing energy for the body to function as it should. By eating a balanced diet, most people should be able to meet their daily requirements for vitamin B-1, but in some cases, supplementation is necessary to avoid deficiency.
