Overview
Collagen is the most abundant protein in your body, it’s the structural framework for skin, bones, muscles, tendons, ligaments, and cartilage. It keeps skin firm and joints comfortable, but production naturally slows from your mid-20s onwards. By the time you reach your 40s, collagen levels can be significantly lower, contributing to changes in skin texture, reduced flexibility, and slower recovery.
Our high-strength Marine Collagen Capsules provide 1,200 mg of sustainably sourced marine collagen peptides, plus Vitamin C to contribute to normal collagen formation for the healthy function of skin, cartilage, bones, gums, and teeth. Taken daily, they help you maintain the building blocks your body relies on for resilience and support.
Who it's for
Adults wanting to support skin firmness, hydration, and elasticity
People looking to maintain joint comfort and mobility as they age
Anyone focused on bone, gum, and connective tissue health
Individuals whose diet or lifestyle may affect natural collagen production (e.g. high sun exposure, smoking, low protein intake)
Not suitable for vegetarians or vegans (sourced from fish)
For best results
We recommend taking 2 capsules daily with water, ideally at least one hour after eating or on an empty stomach.
Consistency matters - visible benefits to skin and joints often appear after 8–12 weeks.
Support your results with a protein-rich diet, regular movement, and healthy skin habits like sun protection
Science & evidence
Collagen is a structural protein made from amino acids. Your body produces it naturally, but age, lifestyle, and environmental factors can speed up its breakdown. Reduced collagen is linked with skin wrinkling, joint stiffness, and muscle loss.
Our hydrolysed marine collagen contains small peptides that are easier to absorb, providing the raw materials your body needs to form new collagen. Vitamin C is essential for this process, so we added it to our capsules, supporting the structure and strength of connective tissues throughout the body.
Collagen and Vitamin C work together to maintain the strength and resilience of your skin, joints, bones, and connective tissues. Vitamin C contributes to normal collagen formation for skin, helping to maintain elasticity and firmness over time. Collagen itself is a key structural component of cartilage, tendons, and ligaments, supporting comfortable movement and flexibility. It also plays a role in bone density and gum health, with Vitamin C supporting collagen formation for both. In addition, collagen peptides provide amino acids used in keratin production, which can benefit the condition of hair and nails.

What is Marine Collagen?
Collagen production in the body naturally begins to decline from your mid-20s. This reduction can be accelerated by factors such as smoking, sun exposure, and a low-protein diet. As collagen levels fall, you may notice reduced skin elasticity, lower hydration, and a loss of firmness, alongside increased joint stiffness and slower recovery.
Our Marine Collagen is hydrolysed into small collagen peptides, making it easier for your body to absorb and use. Once absorbed, these peptides provide the amino acids needed to support the body’s own collagen formation and ongoing maintenance.
Each capsule combines marine collagen with Vitamin C, an essential co-factor in collagen synthesis. Vitamin C contributes to normal collagen formation for the normal function of skin, bones, cartilage, gums, and teeth, helping to support these structures as you age.
Our marine collagen is sourced from fish skin, a by-product of the seafood industry, helping to reduce waste and support a more circular supply chain. It is naturally rich in Type I collagen, the primary form found in skin, bones, tendons, and ligaments, making it particularly relevant for supporting skin structure and connective tissue health.
The collagen is derived from a mix of responsibly sourced farmed and wild-caught fish. Where wild fish are used, they come from non-endangered species to support sustainable sourcing. The raw material is Friend of the Sea certified, providing independent assurance that recognised environmental standards are met. As availability varies, the exact fish species may change over time, but all materials must meet strict quality, safety, and environmental criteria before use.
