- No proprietary blends. Every active is listed at the dose it is actually in there at.
- Contains fish. Not suitable if you're allergic to fish or eat vegan.
One 10 g scoop a day, stirred into whatever you already drink — coffee, tea, water, a smoothie. It dissolves without clumping and doesn't taste of fish.
There are 30 scoops in a tub, so one tub is one month. Take it at the same time every day; the habit matters more than the hour.
Per 10 g scoop. 30 servings per container.
- Fish collagen peptide — 4,500 mg
- Acerola cherry extract — 100 mg
- Vitamin C — 100 mg
- Sodium hyaluronate — 20 mg
- Coenzyme Q10 — 20 mg
- Selenium — 10 mcg
Other ingredients: maltodextrin, sucralose, silicon dioxide.
Contains fish. The collagen is marine-derived, so this is not vegan, not vegetarian, and not suitable with a fish allergy.
If you're pregnant, nursing, taking prescription medication or managing a health condition, check with your doctor before starting any supplement.

Marine Collagen + Vitamin C was made for exactly this stage: 4,500 mg of collagen peptides and 100 mg of vitamin C in one scoop, every day.
What to check on any collagen label
Your body can't build collagen without vitamin C.*
Skin makes less collagen with age.*
Vitamin C is the cofactor for the two enzymes that stabilise each new collagen molecule as it forms.*
So every 10 g scoop carries 100 mg of vitamin C, 111% of the daily value, plus 100 mg of acerola cherry. Collagen and its cofactor, in one scoop.
Check the label of the collagen you use now. If vitamin C isn't listed, it isn't in the tub.
- Collagen peptides4,500 mg
- Vitamin C100 mg
- Daily value111%
Varani et al., Am J Pathol 2006: in the lab, skin cells from people aged 80 and over made 56 ng/ml of type I procollagen, the precursor of collagen; cells from people aged 18 to 29 made 82 ng/ml. On vitamin C: Pullar et al., Nutrients 2017; Gorres & Raines, Crit Rev Biochem Mol Biol 2010.
Three more actives in the scoop
Three more actives, each at its dose.
Sodium hyaluronate · 20 mg
The salt form of hyaluronic acid, a molecule the body also makes itself. 20 mg in every scoop, at the dose printed on the label.
CoQ10 20 mg · selenium 10 mcg
Coenzyme Q10 at 20 mg, and selenium at 10 mcg — 18% of the daily value, a good source. Both printed at their dose, like everything else in the tub.
Every one of them printed at its dose on the label. Nothing hiding inside a blend.
The first 12 weeks
The routine and the research, week by week.
One scoop a day. The stages follow two placebo-controlled trials that gave women aged 40 to 65 fish collagen at 4 to 5 g a day; this scoop has 4.5 g. What each one measured is in the studies cited below.*
-
Day 1
One scoop, in the drink you already make
Stir one 10 g scoop into coffee, tea, water or a smoothie. It dissolves without clumping. Ten seconds.
-
Every day
What's going in
Collagen is the main structural protein in skin.* Each scoop carries 4,500 mg of collagen peptides and 100 mg of vitamin C, the nutrient the body needs to form its own collagen.*
-
Week 8
When the first trial measured skin
Same scoop, every day. In a 2024 placebo-controlled trial, women aged 40 to 60 took 5 g of fish collagen a day, and their skin was measured against placebo at week 8.*
-
Week 12
The length of the second trial
In a 2020 placebo-controlled trial, women aged 40 to 65 took 4 g of fish collagen a day, in a drink with vitamin C and CoQ10, for 12 weeks.* The 3-tub option covers all 12 weeks in one order.
Studies cited Where our research comes from
Morakul et al., J Cosmet Dermatol 2024: 72 women aged 40–60 took 5 g of tuna collagen peptides a day for 8 weeks. Facial hydration and elasticity measured higher than placebo; facial water loss did not differ from placebo.* Funded by a Thai government research programme and Thai Union Group, a seafood company. Žmitek et al., Nutrients 2020: 34 women aged 40–65 took a drink with 4 g of fish collagen, 80 mg of vitamin C and 50 mg of CoQ10 a day for 12 weeks. Dermis density measured higher than placebo; hydration, dermis thickness and elasticity did not differ from placebo.* Publicly funded in Slovenia and by the EU; Valens, the maker of its CoQ10, supplied the drink. A 2025 review of 23 trials found no effect in the trials without company funding, or in the high-quality trials (Myung & Park, Am J Med 2025). These are studies of the ingredient, not of FNDRY products.

Took about 3 weeks
Nothing at all for the first fortnight and I nearly gave up on it. Then around week 3 my face stopped going tight after washing and my foundation stopped clinging round my mouth. Goes into coffee fine, can't taste it.

It's my nails that changed most
Bought it for my skin and it's my nails that are the obvious difference. They used to split at the sides constantly and they just don't now. Skin came later, maybe 2 months before I could really tell.

Works, but the scoop is annoying
No complaints about the actual product, my cheeks aren't as dry and crepey as they were. The scoop is too big for the neck of the tub though so I make a mess most mornings. Hence the 4.

Only noticed when I stopped
Ran out in June and didn't get round to reordering for about six weeks. The tightness came straight back. That told me more than the first three months did, honestly.

Third collagen I've tried, first one I'll rebuy
The other two I couldn't tell you if they did anything. This is the only one that lists what's in it, and it's the only one that's actually changed my skin. Make of that what you will.

My daughter noticed before I did
I'm 51 and everything went downhill at once last year, nothing I put on my face was touching it. Three months in and my daughter asked what I'd changed. Good enough for me.

Asked before buying
The things people want to know first.
Because the body needs vitamin C to form its own collagen — it's the cofactor for the enzymes that stabilise each new collagen molecule.*
There's 100 mg of vitamin C in every scoop — 111% of the daily value — and 100 mg of acerola cherry, a natural source of the same vitamin.
Every day, for as long as it's part of your routine. We plan it in 12-week blocks: three tubs, which is exactly the 3-tub option.
We won't put a date on what you'll see — nobody can honestly promise that for a supplement. What we do promise is on the label: every active, at its dose.
No. It's unflavoured and dissolves without clumping.
Coffee is the easy one. Tea, water, juice and smoothies all work — heat doesn't damage it.
Ours is marine: fish collagen peptides, 4,500 mg a scoop. The practical difference for you is that it contains fish, so it isn't suitable if you're allergic or eat vegan.
No. This is a scoop in your drink, so it replaces nothing you put on your skin. Keep your routine; this adds ten seconds to it.
Yes. Try your first order for 90 days. If it isn't for you, email hello@fndryhealth.com within 90 days of delivery and we'll refund what you paid. No need to send it back. One per customer, first order only, including the first delivery of a subscription. After your first order, our standard 30-day returns on unopened packs apply.
