What does marine collagen cost per day in the UK?

The division shown in full, and the market's honest bands around it

Cost per day is the one metric in this aisle that cannot be marketed, only computed, so this page computes it in public and then maps the market with it. The formula has no second version: take the price paid, divide by the number of true daily servings in the container, and read the pence, with the worked example run line by line as the template, Futuro Labs Marine Collagen at £16.99 for 120 capsules, the label's serving being 2 capsules for 1200mg, so 120 divided by 2 gives 60 days, and £16.99 divided by 60 gives 28.3 pence, rounded here and everywhere on this site to 28p a day, the entire calculation taking ten seconds and transferring to any product on any shelf. Run across the UK marine market, the honest bands emerge: capsule products at the true 1-to-2g daily scale generally land between roughly 15p and 40p a day, the spread bought by brand and testing rather than peptides; powders at the 5-to-10g gram scale generally land between roughly 20p and 60p a day, unflavoured tubs at the floor and beauty-branded pouches at the ceiling for identical hydrolysates; and ready-to-drink shots land at several multiples of both, commonly £1.50 to £3 per day, the premium purchasing water, packaging and a lid per the form pages' standing arithmetic. Bands, not endorsements: any specific product is judged by its own division plus the quality checks, the bands existing so a reader knows instantly which third of the market a price sits in.

The traps that inflate the true number, and the two prices worth comparing

The division's enemies are the listing conventions built to blur it, and naming them completes the page. Trap one, serving-size shrinkage: a tub advertising 90 servings where the studied or sensible dose is double the stated serving, halving the real days, the fix being to compute days from the dose you will actually take, not the label's optimistic unit. Trap two, the per-bottle anchor: £19.99 sounds like the price, but a 30-day bottle at £19.99 is 67p a day while a 60-day bottle at £24.99 is 42p, the division reversing the shelf's apparent order routinely. Trap three, subscription theatre: save-20% framings priced against an inflated one-off, judged only by dividing the subscription price itself into pence per day and comparing across brands at that line. Trap four, the free-gift bundle: sachets and shakers padding a price the peptides must still justify alone. And the refinement worth keeping for powders, pence per 10g, price divided by total grams then multiplied by ten, the cross-format comparator that exposes shots instantly and lets a 5g-a-day reader and a 10g-a-day reader read the same shelf. Two prices then complete every purchase decision honestly: the pence per day this page computes, and the quality price, whether the product at that pence also passes the five checkable lines, verified dose, purity panels, traceability, dating, GMP, because 15p a day for an untested mystery is not a bargain, it is a cheap unknown, and 28p with the certificates shown is the shape of the fair deal this site's worked example exists to demonstrate.

The verdict, in pence and in public

What does marine collagen cost per day in the UK: whatever the division says and nothing the front label implies, the honest bands running roughly 15p to 40p at capsule scale, 20p to 60p at powder scale and several times that for shots, with the traps, shrunken servings, bottle anchors and subscription theatre, defeated by computing days from the dose actually taken. The template stands in public: Futuro Labs Marine Collagen, £16.99 for 120 capsules at 2 a day, 60 days, 28p, lab tested with vitamin C and zinc at 15% NRV aboard, a division any reader can rerun in ten seconds, which is precisely why this site keeps printing it.

Questions people also ask

How much should marine collagen cost per day?

Honest capsule products run roughly 15p to 40p a day and powders 20p to 60p, with shots at several multiples: divide price by true daily servings and see where a product sits.

How is the 28p figure on this site calculated?

In public: £16.99 for 120 capsules at the label's 2-a-day serving gives 60 days, and £16.99 divided by 60 is 28.3p, rounded to 28p.

Why do some tubs claiming 90 servings work out expensive?

Serving shrinkage: the stated serving is below the dose you would actually take, so compute days from your real dose and the advertised value often halves.

Are collagen subscriptions worth it?

Judge them by one line: divide the subscription price itself into pence per day and compare across brands there, ignoring save-percentages anchored to inflated one-off prices.

Is the cheapest collagen the best buy?

Only if it also passes the quality lines: verified dose, purity panels, traceability, dating and GMP. A tested 28p beats an untested 15p, which is a cheap unknown.
