  • Eating foods that contain high amounts of vitamin C (such as oranges), which compete with thiamine for absorption.

Health Issues Caused by Prolonged Vitamin B1 Deficiency

Vitamin B1 deficiency is a health condition that can cause serious health problems. If we don’t get enough daily essential nutrients or constantly practice bad habits that lead to Vitamin B1 deficiency, it can result in (2) health conditions including:

  • Anemia due to a lack of red blood cells or which can be caused by insufficient intake or impaired absorption of iron, folate, and vitamin B12
  • Impaired mental function, such as memory loss and confusion.
  • Heart issues, such as low blood pressure and a rapid heartbeat
  • Vitamin B1 deficiency also can lead to nerve damage in your legs and feet (peripheral neuropathy).

How Can You Consume Vitamin B1?

Vitamin B1 is thiamine, which can be consumed through diet or health supplements. To ensure that you are getting an adequate amount of Vitamin B1 every day, you need to be conscious of what your daily diet looks like. Vitamin B1 can be obtained through food sources such as meat, poultry, fish, milk, and eggs. We will look at food rich in Vitamin B1.

Vitamin B1 Foods

  • Beans – chickpeas, kidney beans, and lentils are good sources of vitamin B1.
  • Spinach –contains a good amount of vitamin B1 and other vitamins such as vitamin C, E, and K. It also provides iron, calcium, magnesium, and phosphorus. Spinach has been found to reduce inflammation in the body by fighting free radicals that cause oxidative stress. Moreover, spinach is rich in antioxidants that (3) help fight cancer cells and boost immunity against viruses and bacteria.
  • Yeast
  • Grain products such as brown rice, whole wheat, and barley
  • Cereals such as corn flakes, oatmeal, and bran flakes
  • Peas and lentils
  • Slices of bread such as white bread, whole grain bread, and rye bread (these foods contain a small amount)
  • Potatoes (also known as potato chips) – are good sources of thiamine, but only if they are made from unrefined potatoes (organic potatoes generally contain more thiamine than non-organic ones). Eating canned or frozen potatoes won’t provide much thiamine because they have been cooked before being canned or frozen, making them less nutritious and more likely to contain chemicals that interfere with the absorption of thiamine by the body.

Vitamin B1 Dosage for Adults

Children aged 4-13 years should take between 0.6- 0.9 mg per day; infants aged 0-3 months should take 0.3 mg per day while newborns should be given 0.2 mg per day.

Vitamin B1 Supplement

Eating nutritious foods is key to living a healthy life since it makes sure that you get all the essential vitamins and minerals you need every day.
