How It Works
How It Works
Biotin functions as a coenzyme in the metabolism of fats, carbohydrates and proteins. It's particularly important for the synthesis of keratin — the structural protein that makes up your hair, nails and skin. Your body uses biotin to help convert nutrients into energy while supporting the production of proteins essential for healthy hair and nail growth.
Who It's For
Adults looking to support hair and nail health, especially those with brittle nails or thinning hair. Ideal for people who want a simple, research-backed B-vitamin without complex formulas. Perfect for those following restrictive diets that may limit biotin-rich foods.
Who It's Not For
Not suitable for children or those taking high-dose biotin supplements from other sources. Consult your healthcare provider if pregnant, nursing, or taking medications.
