What is Vitamin B7?
Vitamin B7 (Biotin) is also known as Vitamin H. Like all B vitamins, it is water soluble and contains sulfur. It is commonly produced by the beneficial bacteria in the gut.
Why is Vitamin B7 important and what does it do in the body?
Like most B vitamins, Biotin is involved in many metabolic functions. It functions in the utilization of sugar, fats and the manufacture of amino acids to make energy and in the growth and replication of cells. It is involved in the formation of strong nails and healthy hair. It helps in the treatment of eczema, seborrheic dermatitis (cradle cap) and alopecia. Biotin also plays an important role in diabetes. It enhances insulin sensitivity and increases the enzyme glucokinase that is responsible for the utilization of glucose by the liver. It also supports a healthy nervous system and is vital for healthy hair because it improves the metabolism of scalp oils. It even helps to reduce the likelihood of grey hair!
Biotin is a critical nutrient during pregnancy as it is important for normal embryonic growth.
What amount of Vitamin B7 do you need each day?
Vitamin B7 can be found in multivitamins and B complex vitamins. Separately, it is sold as biotin. Its most bio-available source is biocytin. Biotin works well with other B vitamins, CoQ10 and Carnitine.

What steals Vitamin B7 from the body?
Alcohol: inhibits the absorption and utilization of Biotin.
Broad spectrum antibiotics: Tetracycline, (Demeclocycline,Doxycycline and Methacycline), Amoxicillin/Clavulanic Acid (Augmentin),Vancomycin - will kill the colonies of beneficial bacteria in the gut that helpmake Biotin.
Anti-seizure medications: Phenytoin (Dilantin), Carbmazepine (Tegratol) and Primidone (Mysoline) deplete Biotin.
High supplementation of Pantothenic acid (Vitamin B5): can decrease absorption as it competes for the same uptake sites in the colonocytes.
What tests can be used to assess Vitamin B7 or Biotin levels?
Urine analysis of alpha-hydroxy-isovalerate (if elevated suggest slow Biotin)
Plasma levels are not very accurate.
