What is Vitamin B7?:

What Is Vitamin B7Vitamin B7, also known as Biotin, is commonly known as the skin vitamin. B7 is one of the eight water-soluble B vitamins and plays an important role in the breakdown of carbs, fats & proteins for fuel as well as the regulation of genes.

Vitamin B7 Discovery:

Vitamin B7 Discovery

Vitamin B7 was discovered as a result of the “egg white injury”, a case in which rats were fed egg whites developed dermatitis and hair loss. Other observations at the time found that raw eggs caused skin lesions to develop which could be cured by compounds found in yeast or liver. 

Uncooked egg whites contain a protein known as avidin, which is a form of anti-vitamin. Avidin strongly binds to biotin (vitamin B7), making it unavailable to be absorbed through the intestines. Normally, egg yolks contain large amounts of Vitamin B7, but the avidin in uncooked eggs can prevent its absorption. Cooking your eggs prevents the avidin protein from binding to Vitamin B7, making eggs a viable source of the B-vitamins and preventing a B7 Deficiency.

Vitamin B7 was originally known as Vitamin H and it did not become known as Biotin until it was isolated from egg yolks by scientists Koegl and Toennis in 1936.

Functions Of Vitamin B7:

Functions of Vitamin B7

The primary function of Vitamin B7 is as a carboxylation enzyme. Carboxylation is the process of adding CO2 to a molecule, which is a necessary step for a number of chemical reactions.

Biotin & Skin Health

Vitamin B7 is normally found in relatively high quantities in the hair and skin. Low levels of Vitamin B7 have been repeatedly associated with thinning hair and brittle nails and vitamin B7 supplementation has been used to improve these symptoms. While B7 is often touted as the ‘hair & mineral’ vitamin, the research shows that the benefits for nails and skin of B7 only occur in those that are deficient in it.

Biotin & Metabolism

Vitamin B7 plays an essential role in the breakdown of amino acids, specifically the branch-chained amino acids, and fats to be used as fuel. Biotin is also required in the process of gluconeogenesis, the conversion of amino acids or fat into glucose. Lastly, B7 plays a role in the synthesis of fatty acids. 

Overall biotin is an extremely important vitamin in metabolism and is necessary for our cells to function properly.

Vitamin B7 Deficiencies:

Vitamin B7 Deficiency

Biotin deficiencies are extremely rare except in cases of extreme malnutrition due to the wide variety of foods that contain Biotin and the ability of certain bacteria in our intestine to manufacture it. Biotin deficiencies can result in 

  • Brittle nails
  • Thinning hair
  • Skin Lesions
  • Dermatitis
  • Conjunctivitis
  • Skin Rashes

Vitamin B7 deficiencies are most common in:

  • Alcoholics
  • People with epilepsy
