Who is likely to be deficient?
A decline in vitamin B1 levels occurs with age, irrespective of medical condition.1 Deficiency is most commonly found in alcoholics, people with malabsorption conditions, and those eating a very poor diet. It is also common in children with congenital heart disease.2 People with chronic fatigue syndrome may also be deficient in vitamin B1.3 4 Individuals undergoing regular kidney dialysis may develop severe vitamin B1 deficiency, which can result in potentially fatal complications.5 Persons receiving dialysis should discuss the need for vitamin B1 supplementation with their physician.
How much is usually taken?
While the ideal intake is uncertain, one study reported the healthiest people consumed more than 9 mg per day.6 The amount found in many multivitamin supplements (20–25 mg) is more than adequate for most people.
Vitamin B1 is nontoxic, even in very high amounts.
Are there any side effects or interactions?
Vitamin B1 works hand in hand with vitamin B2 and vitamin B3. Therefore, nutritionists usually suggest that vitamin B1 be taken as part of a B-complex vitamin or other multivitamin supplement.
