What happens if Vitamin B1 is low?

What causes a B1 deficiency?

(Beriberi; Vitamin B1 Deficiency) A diet consisting mainly of white flour, white sugar, and other highly processed carbohydrates can cause thiamin deficiency.

How long does it take to reverse B1 deficiency?

Does thiamine help thyroid?

Thiamine deficiency has been observed in association with hyperthyroidism. Several studies documented that thiamine treatment could improve signs and symptoms of congestive heart failure, or even improve left ventricular ejection fraction in patients without thyrotoxicosis.

Can you take vitamin B1 with levothyroxine?

No interactions were found between levothyroxine and Vitamin B Complex 100. This does not necessarily mean no interactions exist.

How long does it take to recover from vitamin B1 deficiency?

Many people with beriberi can be treated with thiamine alone. Given thiamine intravenously (and later orally), rapid and dramatic recovery occurs, generally within 24 hours. Improvements of peripheral neuropathy may require several months of thiamine treatment.
