Biotin (Vitamin B7): The Ultimate Guide to Hair, Skin & Overall Health

What is Biotin?

 

Biotin, also known as Vitamin B7, is a water-soluble vitamin that plays a vital role in maintaining your body’s metabolism, hair strength, skin glow, and nail health. It helps convert food into energy and supports keratin production — the protein that makes up your hair, skin, and nails.

If you’re struggling with hair thinning, dull skin, or brittle nails, biotin might be the missing nutrient in your routine.
