Best marine collagen I've used.

Best marine collagen I've used. Mixes well in coffee with a quick stir. Unflavoured really means unflavoured, no fishy aftertaste at all. 9.2g protein per scoop is the macro detail I needed.

Charlotte H. Cheltenham · 10 March 2026

MSC-certified marine sourcing.

MSC-certified marine sourcing was the deciding factor — wanted to know it was sustainable. Three months in, skin and nails are noticeably stronger. Halal certified is rare for marine collagen, this nailed both.

Raksha B. Wembley · 27 February 2026

Quality powder.

Quality powder. Four stars because the scoop tucked in the bag is hard to find amongst the powder — minor packaging gripe. Otherwise the product itself is exactly what it promises. Skin glow is real.

Donna T. Norwich · 9 April 2026

My favourite brand.

Switched from a German brand and saved money for the same quality. Pure collagen, no fillers. Add it to my morning protein shake and don't notice it. Will be reordering.

Marek W. Slough · 31 January 2026

My knees stopped clicking.

9.2g protein per scoop is properly meaningful. Goes into smoothies without changing the texture or taste. Hair, skin, nails all benefit but the joint comfort is what I notice most, knees stopped clicking.
