Dr. Mercola's Hair Skin and Nails aims to support beauty from within by combining three popular ingredients. With a notable 5000mcg of Biotin, it provides a substantial amount of this B-vitamin, often included for its role in the body's keratin production, which is a key protein in hair, skin, and nails.
The inclusion of 500mg of Keratin directly supplies a building block for these tissues, which can contribute to their strength and appearance. Additionally, 20mg of 'low density' Sodium Hyaluronate, a form of Hyaluronic Acid, is present to help the skin retain moisture, potentially leading to a smoother feel and look. This combination targets multiple aspects of skin, hair, and nail support.
