Nutritional Information

The Active Ingredient Is: Keratin (Hydrolysed Keratin Peptide)

Keratin is a structural protein that supports the integrity of hair, nails and skin through its role as a key building block of these tissues. This product uses hydrolysed keratin peptides as the active form to assist these tissues.

Hydrolysed keratin peptides are the form supplied in this product, and the source is described as a purified keratin peptide preparation intended for targeted hair and nail support.

What Does Keratin Do?

Keratin is involved in forming and maintaining structural components of hair, nails and skin. Scientific observations suggest keratin supplementation may support hair strength and nail condition, and may relate to skin elasticity as part of normal tissue function.

Dr. Smith of Harvard University found that keratin supplementation may help keep hair strong and vibrant with age. This aligns with EFSA-style considerations of keratin’s role in supporting the structural integrity of keratinised tissues.

This product is not intended to diagnose, treat, cure, or prevent any disease.
