Vitamin B7 (Biotin)
Overview
Biotin (Vitamin B7) is a water-soluble vitamin that acts as a cofactor for enzymes involved in fatty acid synthesis, glucose metabolism, and amino acid processing. Adults need 30 mcg daily. No upper limit has been established. Critical safety note: high-dose biotin (5–10 mg, common in hair/nail supplements) can interfere with biotin-based lab tests and cause false readings for thyroid hormones, vitamin D, and cardiac troponin. Stop taking biotin at least 24–48 hours before lab tests and inform your doctor.

Alpha-Liponsäure kann die intestinale Biotin-Aufnahme hemmen. Bei hochdosierter Liponsäure-Supplementierung sollte der Biotin-Status beachtet werden.
Alpha-Liponsäure konkurriert mit Biotin um denselben intestinalen Transporter und kann die Biotin-Aufnahme reduzieren. Bei gleichzeitiger Einnahme mindestens 2h Abstand einhalten oder Biotin-Dosis ggf. anpassen.

Hohe Phenylalanin-Spiegel können die Biotinidase-Aktivität hemmen und die Biotinverfügbarkeit beeinflussen. Bei Phenylketonurie oder sehr hohen Phenylalanin-Dosen empfiehlt sich eine ausreichende Biotin-Versorgung.
