Great Lakes Marine Collagen Peptides (Sustainable) 227g – Wild-Caught Whitefish Collagen for Skin, Hair, Nails & Joints

Great Lakes Marine Collagen Peptides are sourced from 100% sustainably wild-caught whitefish — providing a premium, highly bioavailable hydrolysed collagen specifically for support of skin elasticity, hair strength, nail growth, joint cartilage, and connective tissue. Marine collagen is predominantly Type I collagen — the most abundant collagen in human skin, tendons, bones, and ligaments — and its smaller peptide size compared to bovine collagen may enhance intestinal absorption. Unflavoured and odourless — easily added to any food or drink. 227g.

Frequently Asked Questions

What makes marine collagen different from bovine collagen?

Marine collagen (from fish) is predominantly Type I collagen — the same primary type found in human skin, hair, nails, tendons, and bones. Its peptide molecular weight is generally smaller than bovine collagen, which some research suggests may improve intestinal absorption. Marine collagen is also a preferred option for those avoiding beef products. Bovine collagen provides both Type I and Type III collagen (relevant for gut and skin). Both are effective — choice depends on dietary preference and source transparency.

How do collagen peptides benefit skin?

Hydrolysed collagen peptides are absorbed intact into the bloodstream, where they act as signalling molecules — stimulating fibroblasts (skin cells) to produce new collagen, elastin, and hyaluronic acid. Multiple clinical trials show oral collagen peptide supplementation at 2.5–10g daily improves skin elasticity, hydration, and reduces visible wrinkle depth within 8–12 weeks. The effect is particularly meaningful in people over 40, when natural collagen production declines significantly.

How do I use Great Lakes Marine Collagen Peptides?

Mix 1–2 scoops (approximately 10–20g) into any liquid — coffee, tea, smoothies, juice, water — or stir into food like yoghurt, oatmeal, or soup. The hydrolysed peptides dissolve easily in hot or cold liquids without clumping. The unflavoured formula has no taste or odour, making it undetectable when mixed into food or drink. Take daily for best results.

How long until Great Lakes Marine Collagen shows results?

Joint and muscle recovery improvements are often noticed within 4–6 weeks. Skin improvements (elasticity, hydration) typically develop over 8–12 weeks of daily use. Hair and nail strength improvements are measured in growth cycles — allow 3–6 months for significant changes. Collagen's structural benefits are cumulative with consistent daily supplementation.

Is Great Lakes Marine Collagen sustainable?

Yes — Great Lakes Marine Collagen is sourced from 100% sustainably wild-caught whitefish using responsible fishing practices. The use of fish skin and scales (typically discarded in food processing) for collagen extraction is an example of utilising previously wasted raw materials — providing a more environmentally responsible collagen source than some farm-raised alternatives.
