Marine collagen is one of the most popular supplements in the world — and for good reason. Sourced from wild or sustainably farmed fish, this pure form of collagen is known for its exceptional absorption, skin-enhancing benefits, and support for healthy joints and bones. It’s nature’s way of promoting beauty and wellness from within.
What Is Marine Collagen?
Marine collagen is derived from the skin, scales, and bones of fish, most commonly cod or snapper. It primarily contains Type I collagen — the same type found abundantly in human skin, tendons, and ligaments. When hydrolysed into peptides, marine collagen becomes highly bioavailable, meaning your body can absorb and utilise it efficiently.
Key Benefits of Marine Collagen
- Promotes youthful skin: Helps reduce fine lines, improve elasticity, and support skin hydration by stimulating your body’s natural collagen production.
- Strengthens hair and nails: Provides amino acids like glycine and proline, which nourish keratin structures for stronger, shinier hair and nails.
- Supports joint and bone health: Contributes to cartilage repair, reduces stiffness, and maintains bone density — essential for active lifestyles and healthy aging.
- Gut health benefits: Collagen peptides may help support gut lining integrity, assisting with digestion and overall wellness.
- High bioavailability: Marine collagen is absorbed up to 1.5 times more efficiently than bovine collagen, delivering faster visible results.

Tip: Pair your collagen supplement with vitamin C (from citrus or a supplement) to maximise collagen synthesis and absorption.

Marine collagen is ideal for anyone looking to improve skin elasticity, support joint mobility, or maintain a youthful appearance. It’s especially beneficial for women over 40, athletes, and individuals recovering from joint or tendon strain.
