What collagen actually costs per serving
Pack price tells you almost nothing useful. A 500g tub at £40 can be worse value than a 250g tub at £25, depending on the serving size. This page breaks down our own products honestly, including where one format works out more expensive than another.
Bovine collagen powder — 83p per serving
Our bovine collagen powder comes in a 300g tub. One serving is a 10g scoop, so you get 30 servings per tub. Each serving delivers 10,000mg of hydrolysed bovine collagen peptides.
| Format | Tub size | Servings | Collagen per serving | Cost per serving |
|---|---|---|---|---|
| Bovine powder | 300g | 30 | 10,000mg | 83p |
It dissolves in hot or cold liquid. Stirring into coffee or tea is fine — the peptides are already hydrolysed, so heat does not change the composition. Neutral in flavour.
Marine collagen powder — £1.16 per serving
Our marine collagen powder comes in a 250g tub. One serving is again a 10g scoop, giving 25 servings per tub and 10,000mg of hydrolysed marine collagen peptides per serving.
| Format | Tub size | Servings | Collagen per serving | Cost per serving |
|---|---|---|---|---|
| Marine powder | 250g | 25 | 10,000mg | £1.16 |
Marine collagen costs more per serving than bovine. That reflects the sourcing — marine collagen is more expensive to produce. The serving size and peptide dose are identical; you are paying for a different raw material, not a larger amount.
It dissolves cleanly in hot or cold liquid and has no fish flavour, despite coming from a fish source. That surprises most people who try it.
Compare bovine or marine? Neither is better. They suit different people.
Collagen capsules — significantly less per serving
Our collagen capsules contain 400mg per capsule. A standard two-capsule serving delivers 800mg of collagen.
| Format | Collagen per serving | Notes |
|---|---|---|
| Capsules (2 caps) | 800mg | Convenient format; substantially less collagen per serving than powder |
| Bovine powder (1 scoop) | 10,000mg | 12.5× more collagen per serving |
| Marine powder (1 scoop) | 10,000mg | 12.5× more collagen per serving |
Capsules are a legitimate format if you travel frequently, dislike mixing powders, or want something you can take at your desk without a shaker. But on a straight cost-per-milligram basis, they are the most expensive way to take collagen we sell. That is worth knowing before you buy.
Why milligrams per serving matters more than pack price
The collagen market has a habit of displaying large numbers prominently — "10,000mg", "5,000mg", "2,500mg" — without making it obvious that these refer to the dose per serving, not the total content of the pack.
When you are comparing products across brands, the only number that matters for value is:
- How many milligrams of collagen per serving?
- How many servings in the pack?
- What is the total price divided by the number of servings?
A £15 pack with 15 servings at 5,000mg each costs £1.00 per serving and delivers 5,000mg. A £25 pack with 30 servings at 10,000mg each costs 83p per serving and delivers twice the collagen. The second is cheaper and larger by both measures, but the £15 headline price looks more attractive.
Pack weight is also not a reliable proxy. Collagen powder is relatively dense, but some products include fillers, flavourings or anti-caking agents that add weight without adding collagen. Check the collagen content per 100g on the nutrition panel, not just the serving size.
10,000mg versus the common 5,000mg dose
Many collagen products on the UK market use a 5,000mg serving. Both our bovine and marine powders use a 10,000mg serving. Here is what that means in practical terms:
| Dose per serving | Scoop size (approx.) | Servings from 250g tub |
|---|---|---|
| 5,000mg | 5g | 50 |
| 10,000mg | 10g | 25 |
A brand selling a 250g tub with a 5,000mg serving can advertise "50 servings" and look better value than our 25-serving tub at the same price. They are the same amount of collagen. The difference is how many scoops you take per day.
If you want to take 10,000mg daily from a 5,000mg product, you use two servings and halve the number of days the tub lasts. The cost per day ends up the same. The 50-serving count is not wrong — it is just calculated on a smaller serving than the one most people use.
We use 10,000mg per serving because that is the dose most people are looking for when they buy collagen powder. One scoop, once a day.
A straightforward comparison
| Product | Pack size | Servings | Collagen per serving | Cost per serving | Format |
|---|---|---|---|---|---|
| Bovine collagen powder | 300g | 30 | 10,000mg | 83p | Powder |
| Marine collagen powder | 250g | 25 | 10,000mg | £1.16 | Powder |
| Collagen capsules | — | — | 800mg (2 caps) | Higher per mg | Capsule |
Both powders are unflavoured and packed in the UK. The bovine version is the lowest cost per serving we offer. The marine version costs more because the raw material costs more — that is the whole explanation.
