How it works
Biotin acts as a coenzyme in carboxylase enzymes, essential for fatty acid and amino acid metabolism. These processes are vital for the synthesis of keratin, the primary structural protein in hair, skin, and nails.
Who should take it
Adults looking to address dull skin, hair thinning, premature ageing. Particularly relevant for people who prefer a targeted single ingredient and who have ruled out an underlying condition that needs medical care first.
Avoid / careful
Pregnant or nursing women without clinician oversight. People on prescription medication affecting the same pathway should consult a doctor before combining. Side effects are uncommon at recommended doses but mild GI upset can occur when starting.
