Characteristics & nutrition facts

Biotin (vitamin B7) is a water-soluble vitamin that becomes a cofactor for carboxylase enzymes, taking part in energy metabolism and fatty acid synthesis. It is connected with the formation of the structural proteins of skin, hair, and nails, so it is widely used as a beauty supplement, and deficiency is on the rare side with a typical diet. It is found in egg yolk, nuts, liver, and the like.

How to manage

Checking the labeled dose and basing it on a balanced diet is generally recommended. High-dose biotin can affect some blood-test values such as thyroid and cardiac markers, so if you have a test coming up, informing the medical staff in advance that you are taking it is recommended. Excessive intake of raw egg white can hinder biotin absorption.

Good to know alongside

It is explained bundled together with the vitamin B group (such as B5, pantothenic acid) and is frequently connected with hair and nail concerns. If hair loss or nail abnormalities are severe or persist, consulting a dermatologist is recommended.

Everyday care tips

If you have a blood test scheduled, it is best to discuss pausing intake a few days beforehand with your medical staff, and eggs should be eaten cooked to reduce the hindrance to biotin absorption.
