Good to know

A vitamin B1 test is recommended to those who consume lots of refined (processed) carbohydrates or alcohol, who take diuretics, and to those who have chronic hepatic or renal diseases, or diabetes mellitus. More vitamin B1 is required during pregnancy and breastfeeding. 

The majority of people have no idea that they might have a vitamin B1 deficiency, because the majority of the symptoms are subtle and often imperceptible:

  • headaches
  • decreased appetite or its loss
  • fatigue
  • weakened memory
  • changed coordination of motions
  • numbness of the arms
  • increased sensitivity
  • disturbed vision
  • disturbed digestion
  • constipation

Long-term deficiency of vitamin B1 may cause beriberi disease damaging the nervous, digestion, and cardiovascular systems. 

Vitamin B1 is soluble in water; consequently, any excess is excreted with urine.
