The Top 10 Vitamin B1 Rich Foods + Recipes

What is Vitamin B1?

Vitamin B1 is also known as Thiamin or Thiamine. It is a water soluble and therefore is not likely to cause toxicity in the body, as any surplus is commonly excreted. The body finds it challenging to store large amounts of vitamin B1 and a constant supply is needed from the food we eat (the top ten Vitamin B1 rich foods are listed below) or from a supplement.

Why is Vitamin B1 important and what does it do in the body?

Like many B vitamins, Vitamin B1 is very important for the success of many body reactions. It helps make energy from the burning of carbohydrates, fats and protein and is commonly known as one of the energy vitamins. It is required to ensure that there are appropriate levels of oxygen in the blood for optimal release of energy by the body’s cells.

What amount of Vitamin B1 do you need each day?

This is always a challenging question, as recommended daily allowances are really only to prevent illness and disease from occurring. If your body is very active and requires more energy to be made then it will use up more Vitamin B1 and therefore your intake will be greater than an individual who is in large sedentary or inactive. Women who are lactating, and individuals under more stress, illness or recovering from surgery require additional Vitamin B1.

As a basic rule of thumb...

Pediatric

  • Newborns - 6 months: 0.2 mg (adequate intake)
  • Infants 7 months - 1 year: 0.3 mg (adequate intake)
  • Children 1 - 3 years: 0.5 mg (RDA)
  • Children 4 - 8 years: 0.6 mg (RDA)
  • Children 9 - 13 years: 0.9 mg (RDA)
  • Men 14 - 18 years: 1.2 mg (RDA)
  • Women 14 - 18 years: 1 mg (RDA)

Adult

  • Men 19 years and older: 1.2 mg (RDA)
  • Women 19 years and older: 1.1 mg (RDA)
  • Pregnant or breastfeeding women: 1.4 mg (RDA)

Daily recommendations for dietary vitamin B1 according to the National Academy of Sciences are listed below.

Recommended Daily Allowance 1.4mg/Day

Optimal Daily Allowance 35mg/Day but may be increased to 200mg/day.

What are possible Vitamin B1 excess symptoms?

Headaches. Seizures and Arrhythmia. Thiamine is generally safe however very high doses may cause stomach upset.

What steals Vitamin B1 from the body?

Heating and cooking can reduce the availability of Vitamin B1 as it may damage it during the process. 

Taking other single B vitamins over a prolonged time may disturb the levels of vitamin B1 so it is recommended that additional B vitamins such as B2, B3, B5, B6, Biotin, Folic acid and B12) are taken together as a complex multi B vitamin.

Alcohol reduces Vitamin B1 levels in the body, as will certain drugs such as Diuretics (Furosemide (Lasix), Bumetamide (Bumex), Torsemide (Demadex) and Ethacrynic Acid (Edecrin) and Dilantin. 

Broad spectrum antibiotics (as these kill of beneficial bacteria in the gut that actually make B vitamins) and certain foods and drinks such as sulfites, tea, coffee and decaf coffee can inactivate Vitamin B1.
