The Active Ingredient Is: Collagen (Marine)

Collagen is a structural protein that supports the framework of connective tissues, including skin, nails, hair, joints and bones. This product centres on a single-ingredient formulation of marine collagen peptides sourced from wild-caught fish in a hydrolysed form for rapid utilisation by the body.

This formulation emphasises a marine collagen source providing Type I collagen peptides to support the body’s natural connective tissue functions.

What Does Collagen Do?

Collagen peptides are absorbed and incorporated into connective tissues, which can support skin hydration and elasticity and help maintain joint comfort and resilience. The peptides may stimulate production of new collagen, elastin, and hyaluronic acid in the skin and joints, contributing to overall connective tissue health.

This is aligned with scientific discussions of marine collagen peptides as a normal part of connective tissue maintenance and function.
