Vitamin B1, often known as thiamine, is a water-soluble vitamin that belongs to the B-vitamin group. Its importance stems from its essential role in the body’s metabolism and overall well-being. Thiamine functions as a coenzyme, actively engaging in a variety of metabolic activities, particularly those involving carbohydrate metabolism. It works as a catalyst in the conversion of glucose into energy, a process critical for providing cells with the energy they require to function properly. Thiamine helps the nervous system by facilitating the manufacture of neurotransmitters and maintaining the integrity of the protective sheath around nerve cells known as myelin. Although thiamine shortage is uncommon in well-balanced diets, it can cause health problems such as weariness and weakness.

  • Energy Production: Thiamine, or vitamin B1, is an essential component of the body’s energy production processes. Thiamine contributes considerably to glucose metabolism by acting as a coenzyme in critical metabolic processes. Thiamine is required for the conversion of glucose into ATP, the chemical that stores and distributes energy within cells, according to research. Thiamine insufficiency can cause weariness, weakness, and low energy levels because cells struggle to make enough ATP to meet their metabolic demands. Thiamine supplementation or consuming thiamine-rich foods can assist meet the body’s energy requirements, enhancing vigour and endurance.

  • Brain Health: Thiamine is important for brain health and cognitive function. Thiamine is required for the manufacture of neurotransmitters such as acetylcholine, which is vital for nerve signal transmission and memory and learning. Furthermore, thiamine is necessary for the integrity of myelin, the protective sheath that surrounds nerves. According to research, thiamine deficiency can cause neurological illnesses such as Wernicke-Korsakoff syndrome, which is characterised by memory problems and disorientation. Adequate thiamine consumption, whether from food or supplements, is critical for proper brain function and neurological well-being.
  • Heart Health: Thiamine’s advantages include improved heart health. Thiamine has been shown in studies to be involved in the regulation of cardiac muscle contractions, ensuring that the heart functions properly. Thiamine deficiency can cause cardiovascular problems such as heart failure. Thiamine supplementation has been proven in studies to improve heart function and may aid in the management of heart-related disorders. However, it is critical to seek personalised guidance on thiamine consumption from a healthcare practitioner, especially if one has specific cardiovascular issues.

Despite these benefits, it is critical to emphasise the significance of speaking with a healthcare provider before contemplating thiamine supplementation, as individual needs and potential interactions with drugs or medical conditions may differ. A healthcare practitioner can provide specific counselling to ensure that thiamine is used safely and effectively for overall health and well-being.


When vitamin B1, commonly known as thiamine, is consumed by food, it plays an important part in a variety of physiological processes. Thiamine is predominantly absorbed in the small intestine after intake. Once absorbed, it is converted into its active form, thiamine pyrophosphate (TPP), which is required for biological processes.

Thiamine’s major function is as a coenzyme, helping in a variety of biochemical activities within cells. One of its primary roles is carbohydrate metabolism, specifically the breakdown of glucose to provide energy. TPP functions as a cofactor for enzymes involved in the citric acid cycle, also known as the Krebs cycle, which is a critical component of cellular respiration. This cycle produces adenosine triphosphate (ATP), the body’s principal energy currency. Thiamine’s role in this mechanism ensures that cells have enough energy to function. Furthermore, thiamine promotes the health of the nervous system by aiding in the manufacture of neurotransmitters and the maintenance of myelin, the protective sheath that surrounds nerves and aids in nerve signal transmission.


The daily recommended consumption of vitamin B1, also known as thiamine, varies depending on age and gender. The recommended dietary allowance (RDA) for adult males is 1.2 mg per day. Adult females over the age of 18 should aim for 1 mg daily, whereas adult females over the age of 19 should aim for 1.1 mg daily. During pregnancy and lactation, the RDA is increased to 1.4 mg daily to support the mother’s and child’s particular nutritional needs.

Recommended doses for children vary by age, and it is best to contact with a healthcare expert to identify the best dosage for specific health conditions or concerns. Thiamine is found naturally in a variety of foods, including cereal grains, beans, nuts, and meat, making it easily available through a well-balanced diet.
