Hydrolysed, from fish
Marine collagen peptides
4,500mg per 10g scoop
- What it is
Collagen is the main structural protein in skin.* Ours is marine: fish collagen peptides, 4,500mg in every 10g scoop.
Hydrolysed means the protein has been cut into short peptides. Like any protein you eat, they are digested into shorter peptides and amino acids.
- Why it's in here
This is the ingredient the whole product is built around, so it is the biggest number on the label: 4,500mg of peptides in every scoop.
It is also why the scoop is 10g — there is no way to fit 4,500mg of collagen into a 2g sachet or a single capsule.
- What the research looked at
In a 1987 study of women after menopause, skin collagen content fell by 1 to 2% a year (Brincat et al., Obstet Gynecol 1987).
Two randomised, placebo-controlled trials gave women aged 40 to 65 fish collagen at 4 to 5g a day. This scoop has 4.5g.
In a trial published in 2024, 72 women aged 40 to 60 took 5g of tuna collagen peptides a day for 8 weeks. Facial skin hydration rose 68.2% on average, against 3.5% on placebo, and facial elasticity rose 16.2%, against a 10.6% fall on placebo.* Water loss through facial skin did not differ from placebo. It was funded by a Thai government research programme and Thai Union Group, a seafood company (Morakul et al., J Cosmet Dermatol 2024).
In a trial published in 2020, 34 women aged 40 to 65 took a drink with 4g of fish collagen, 80mg of vitamin C and 50mg of CoQ10 a day for 12 weeks. Dermis density rose 16.1% against placebo.* Skin hydration, dermis thickness and elasticity did not differ from placebo. It was publicly funded in Slovenia and by the EU, and Valens, the maker of its CoQ10, supplied the drink (Žmitek et al., Nutrients 2020).
Fish collagen peptide, 4,500mg per 10g scoop. A tub is 30 scoops: $39.99, or $1.33 a day.
A 2025 review of 23 trials found improvements in skin hydration, elasticity and wrinkles overall, and no effect in the trials without company funding or in the high-quality trials (Myung & Park, Am J Med 2025). Made from fish. Not suitable with a fish allergy, and not vegetarian or vegan.
