Marine Collagen
Why we made this
Marine collagen has the smallest peptide size and highest concentration of Type I — the collagen that matters most for skin. We chose cod because it's the least allergenic marine source.
1 scoop in coffee, matcha, or a smoothie. Slight neutral profile.
Skin and hair support, pescatarians, and anyone who prefers marine over bovine.
What's inside
Hydrolyzed marine collagen peptides (from wild cod skin).
Where it comes from
Wild-caught cod from MSC-certified Icelandic and Norwegian fisheries. Byproduct utilization — no fish are caught for collagen production.

Third-party COA on the website sold me. Marine Collagen has become part of my morning stack — no chalky aftertaste and no bloat.
I train five days a week and recovery has been sharper. Ingredient list reads like a dietitian wrote it, which is basically the case.
Flavor is subtle in the best way. I'd love a family-size option of Marine Collagen.
Tried AG1 and Ritual before this. Rivergrove wins on transparency and taste. Subscribe-and-save makes it a no-brainer.
She specifically flagged the sourcing standards. I've been on it three months and my labs improved at my last check-in.
Mixes clean in water, no gritty settle. Packaging is a little bulky but I'll take it for the quality.
I'm picky about what goes in my body during pregnancy planning. Rivergrove passed my OB's review.
You get what you pay for. Marine Collagen is not the cheapest option but the quality is obvious after two weeks.
