The Active Ingredient Is: Collagen (Hydrolyzed)

Collagen is a structural protein that is a normal part of connective tissue throughout the body. This form is hydrolysed, meaning its peptide bonds are broken to aid absorption.

Hydrolysed collagen is supplied as a source of collagen peptides and is commonly used to support connective tissue health in skin, hair and nails. This formula also has included biotin, which supports its role in maintaining these tissues.

What Does Collagen Do?

Collagen plays a role in contributing to skin elasticity and hydration in line with supported evidence on skin physiology. It is involved in the maintenance of healthy connective tissue as part of normal body function.

In research contexts, studies indicate improvements in skin elasticity and hydration with hydrolysed collagen supplementation, reflecting its potential to support skin health as described in clinical assessments.

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