Best Vegan Sources of Biotin

Whether you’re following a vegan diet for health or ethical reasons, one of the challenges of a vegan diet is getting enough of the daily requirements of the B vitamins. It’s important to know what are the best vegan sources of biotin (Vitamin B7) and the other B vitamins.

What is Biotin?

Biotin (Vitamin B7 in the United States) is an important water-soluble micronutrient for healthy hair, bone, and nails. Biotin is also important for fatty acid metabolism, the breakdown of certain amino acids as well as the production of glucose (gluconeogenesis) in the body.

Biotin is crucial in several chemical reactions in the body and is required for carbohydrate metabolism. Biotin supplementation may help with blood sugar control in diabetics. (1)https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3679599/

Biotin is classified as a vitamin because the body is not capable of making it and needs to get this important chemical from food sources.

Biotin is also important during pregnancy for a healthy growing fetus. (2)https://www.researchgate.net/publication/288247552_Biotin_Critical_for_fetal_growth_and_development_yet_often_overlooked But despite biotin’s importance for fetal development, there is no standard daily requirement and biotin (vitamin B7) is not included in most prenatal vitamins.(3)https://journals.lww.com/nutritiontodayonline/Abstract/2012/03000/Biotin___Critical_for_Fetal_Growth_and_Development.10.aspx

Facts about Biotin

  • Biotin was originally classified as Vitamin H by the Hungarian researcher Paul Gyorgy.
  • Biotin is referred to as Vitamin B7 in the US while some European countries use Vitamin B8 because inositol is referred to as Vitamin B7.

Symptoms of Biotin Deficiency

Symptoms of biotin deficiency can include:

  • Brittle hair and nails
  • Depression
  • Skin rashes
  • Problems with glucose metabolism
  • Redistribution of fat on the face
  • Seizures (in rare cases)

How much biotin do you need?

There’s no consensus on the daily minimal amount of biotin needed, but the US and European guidelines have set a minimum daily requirement of 30 micrograms. However, that is only the minimal amount needed and there isn’t a guideline on the daily dose of biotin needed for optimal health, but it may be higher than 30 micrograms a day.

Pregnant women may need a higher level of biotin for the developing fetus. Diabetics may also require a higher daily intake of biotin to help stabilize their glucose metabolism. (4)https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3679599/

What foods are high in biotin?

The foods highest in biotin (Vitamin B7) tend to be from animal sources and include (5)https://journals.lww.com/nutritiontodayonline/Abstract/2012/03000/Biotin___Critical_for_Fetal_Growth_and_Development.10.aspx

  • Beef Liver
  • Chicken Liver
  • Egg yolks
  • Fatty fish such as salmon

Obviously none of those foods would be appropriate on a vegan diet, so lets look at what vegan foods have a high amount of biotin
