What is biotin?

Biotin, also known as vitamin B7 or vitamin H, is one of the water-soluble vitamins of the vitamin B complex. It plays a role as a cofactor for numerous enzymes and is known for its function in energy metabolism and for the maintenance of normal skin, hair, and mucous membranes.

Biotin – Effects in the body

Biotin acts as a cofactor in various metabolic pathways:

• contributes to normal energy metabolism
• contributes to the normal function of the nervous system
• contributes to the maintenance of normal skin
• contributes to the maintenance of normal hair
• contributes to the maintenance of normal mucous membranes
• contributes to normal psychological function
• contributes to the normal metabolism of macronutrients (carbohydrates, proteins, fats)

These statements are approved health claims according to EU Regulation (EC) No. 1924/2006.

Daily requirement and biotin deficiency

1. Recommended intake according to DGE: 40 µg per day for adults
2. Biotin deficiency is rare, but can occur in:

• very one-sided diet
• parenteral nutrition (infusion therapy) without supplementation
• Pregnancy and breastfeeding (increased need)
• Taking certain medications (e.g. anticonvulsants)

Foods high in biotin

• Beef liver - 100–130µg/100 g
• Egg yolk - approx. 50µg/100 g
• Soybeans - approx. 60µg/100 g
• Oat flakes - approx. 20µg/100 g
• Walnuts - 15–20µg/100 g
• Mushrooms - approx. 16µg/100 g

💡 Note: Raw egg whites contain avidin, which binds to biotin and inhibits its absorption. Heating inactivates avidin.
