Activity Description

Thiamine, also known as thiamin and vitamin B1, is one of the 8 B-complex vitamins and is classified as a water-soluble B vitamin. Thiamine occurs naturally in specific diets, is added to food products, and is available in dietary supplements. Brown rice, whole grains, pork, poultry, soybeans, nuts, peas, dried beans, and fortified or enriched grain products such as bread, cereals, and infant formulas are rich sources of thiamine. Multivitamins supplement an additional 1.5 mg of thiamine to a diet already abundant in this essential vitamin.

In prolonged or untreated vitamin B1 deficiency cases, individuals may experience advanced-stage symptoms, which can lead to the development of the Wernicke-Korsakoff syndrome. Thiamine is approved by the United States Food and Drug Administration (FDA) for the treatment of Wernicke encephalopathy, infantile beriberi, and cardiovascular disease resulting from thiamine deficiency. Vitamin B1 deficiency may present with early or advanced symptoms. Early symptoms mainly arise from neurological, cardiac, and gastrointestinal systems. Due to thiamine's limited storage duration before rapid excretion, maintaining adequate blood serum levels requires a consistent and regular dietary intake. This activity outlines the indications, mechanism of action, administration methods, significant adverse effects, contraindications, and monitoring protocols for vitamin B1. This activity also equips clinicians to guide patient therapy in treatment or supplementation scenarios where thiamine is indicated by collaborating with dieticians, pharmacists, and primary care clinicians as part of the interprofessional team to enhance patient outcomes.


Target Audience

This activity has been designed to meet the educational needs of physicians.

Learning Objectives

At the conclusion of this activity, the learner will be better able to:

  • Identify early and advanced symptoms of vitamin B1 deficiency, including neurological, cardiac, and gastrointestinal manifestations.

  • Screen patients at risk of vitamin B1 deficiency, considering factors such as alcohol use disorder, poor nutrition, fasting, restricted food access, persistent vomiting, and impaired thiamine absorption.

  • Implement evidence-based interventions for vitamin B1 deficiency, utilizing appropriate treatment modalities such as dietary recommendations, thiamine supplementation, or multivitamin therapy.

  • Collaborate with interprofessional healthcare teams to coordinate comprehensive care plans for individuals with vitamin B1 deficiencies, considering the broader context of patient health and lifestyle.
