How does thiamine work?
Thiamine helps the body convert carbohydrates into energy and supports the normal function of the nerves, heart, and brain.
What is thiamine used to treat?
Thiamine is commonly prescribed for:
- Thiamine deficiency (caused by poor diet, alcoholism, or malabsorption disorders)
- Wernicke-Korsakoff syndrome (a brain condition linked to severe thiamine deficiency in alcohol dependency)
- Beriberi (a rare condition caused by extreme deficiency)
- Supporting energy production in people with chronic fatigue or nerve conditions
Who can take thiamine?

Can I take thiamine if I’m pregnant or breastfeeding?

How effective is thiamine?
Thiamine is highly effective at preventing and treating deficiency-related conditions when taken as directed.
What should I do if I take too much?
