- Cost per 1,000mg is not the same as "best product" — marine, bovine, and plant-based collagen aren't interchangeable, and this table doesn't distinguish quality or bioavailability, only price against labelled quantity.
- It doesn't measure convenience. Jelly sticks need no water or mixing; the sachet and powder products here generally do. Cheaper per mg isn't the same as easier to actually use daily — see our full format comparison for that trade-off.
- Only products with a dose stated on the retailer's own listing are included. Several jelly sticks we track elsewhere on this site (FOODOLOGY, YIXO, HAMCHOROK) aren't here because their listing doesn't state an exact mg figure — see our full where-to-buy guide for those, honestly labelled as "not stated."

UK Collagen Price Index: Cost Per 1,000mg, Compared
The honest answer up front: Absolute Collagen Premium Marine Collagen Powder is currently the cheapest way to buy collagen in the UK by dose, at roughly £0.30 per 1,000mg — a powder sachet, not a jelly stick. This page compares real, currently-available UK collagen products (jelly sticks and otherwise) on price per 1,000mg of actual labelled collagen, not pack price alone, so a £64 pack and a £16 pack can be compared fairly.

Why this exists: pack price alone is a bad way to compare collagen products — packs vary wildly
in size and dose. Every figure below is pack price ÷ total collagen content of the pack, using only the dose
stated on the retailer's own listing. Nothing here is an estimated or invented dose.
Cost per 1,000mg, cheapest first

| Zooki Marine Collagen (Regular Strength) | Liquid sachet | 14 sachets | 5,000mg / serving | £23.99 | £0.34 |
| Cloo9 Collagen Jelly | Jelly stick | 28 sticks | 5,000mg / serving | £64 | £0.46 |
| NOW Foods Collagen Jelly Beauty Complex | Jelly stick | 10 sticks | 2,500mg / serving | £16.03 | £0.64 |

What you're actually paying the premium for: jelly sticks in this comparison cost roughly
1.5x–5.6x more per 1,000mg than the cheapest sachet here. That premium buys
no water, no mixing, and no shaker bottle — one tear-open pouch, a fixed dose, done. If price per mg is your
only priority, sachets win outright. If daily consistency and convenience matter more to you than getting the
cheapest 1,000mg on paper, that's what the extra cost is actually for.

Common questions
What is the cheapest way to buy collagen in the UK by dose?
Currently Absolute Collagen Premium Marine Collagen Powder, at roughly £0.30 per 1,000mg of collagen — a powder sachet, not a jelly stick. Checked September 2026.
Are collagen jelly sticks more expensive than powders or liquid sachets, per mg of collagen?
Generally yes, in this comparison — the two liquid/powder sachet products checked here work out cheaper per 1,000mg of collagen than most of the jelly sticks. Jelly sticks compete on convenience (no water, no mixing, one fixed dose), not on being the cheapest way to get collagen.
How is "cost per 1,000mg" calculated on this page?
Pack price divided by total collagen content of the whole pack (dose per serving × number of servings), then scaled to a 1,000mg unit. Only products with a collagen dose actually stated on the retailer's own listing are included — nothing here is an estimated or invented figure.
A reminder on claims: the only collagen-related health claim authorised in the UK/EU is that
Vitamin C contributes to normal collagen formation for the normal function of skin. This page compares price
and labelled dose only — it isn't a claim that any product here "works" better than another; see our
evidence roundup for what the research actually says.
