TALKING FORMULATION: MARINE COLLAGEN PEPTIDES
What does it take to formulate a good collagen?
The collagen conversation has become noisy. Higher doses. Smaller peptides. Better absorption. Every brand seems to claim they have the “best” collagen.
We sat down with Jessie, the Product Manager who led the development of Marine Collagen Peptides, to walk us through the formulation decisions behind the product—and explain what actually matters.
01Sourcing
You source your marine collagen from wild-caught Norwegian cod. What led you to that decision, and what difference does it make in the final collagen?
Cold-water fish naturally produce collagen that's highly suitable for supplementation, and Norwegian cod has some of the best-established sourcing standards in the industry.
Beyond the ingredient itself, we cared about consistency. Our supplier offers full traceability, sustainable sourcing, and strict quality control from catch through production.
It also produces a collagen that's very clean in taste and smell, which matters more than people realise when you're taking it every day.
02Absorption
Consumers hear terms like “hydrolysed collagen” and “low molecular weight” all the time. What do they actually mean, and how do they affect absorption?
Hydrolysed means the protein has been broken into smaller peptide chains. Low molecular weight, under 5,000 Daltons, means those chains absorb intact into your bloodstream rather than breaking down into generic amino acids.
That intact absorption is what triggers your body’s own collagen production.

<5,000 Da
The molecular weight cutoff for collagen peptides to absorb intact into your bloodstream.
5–10g
The daily dose range where efficacy plateaus. More than that is just a bigger bill.

The vocabulary
Hydrolysed
Collagen that's been enzymatically broken into smaller peptides, making it easier to digest and absorb.
Low molecular weight
Refers to the size of the collagen peptides. Smaller peptides are generally absorbed more efficiently than larger proteins.
Hydroxyproline
An amino acid found in high concentrations in collagen. It's often used as one indicator of collagen quality and purity.
03Formulation
Collagen isn’t the only ingredient in your formulations. How do you decide which vitamins, botanicals, or other actives genuinely complement it?
We don't add ingredients simply because they're popular.
Every addition needs a reason to be there. We look at the clinical evidence, whether the mechanism makes sense alongside collagen, and whether it genuinely improves the overall formula.
Only ingredients that meaningfully enhance the overall formula make the cut.
04The hard part
When you’re formulating a collagen supplement, what’s the biggest challenge? Efficacy, taste, stability?
Striking the right balance: premium, sustainable sourcing, efficacy, taste, stability, and a price point that’s accessible. Every decision pulls in multiple directions, and getting all of them right in a single product is where the real work happens.

Specificity is what does the work, not just size.Jessie · Product Manager, The Purest Co
05What’s overhyped
Collagen research has exploded in recent years. Which findings have genuinely changed how you formulate, and which claims are overhyped?
The obsession with molecular weight has been overhyped. Smaller molecules get you in the door, but what happens after it enters your bloodstream? Does it actually reach your skin?
Specific-sequenced peptides carry a targeted signal for skin regeneration. Specificity is what does the work, not just size.
06No results?
If someone took your collagen every day for six months and didn’t notice results, what would you want to know before concluding it wasn’t working?
The first thing I’d ask is whether they’re living a lifestyle that supports it, because uncontrolled diet, UV exposure, and poor sleep break down collagen faster than any supplement can replenish it.
If those fundamentals aren’t in place, the results will always feel underwhelming, no matter how good the product is.
07The misconception
What’s the biggest misconception about collagen supplements you wish consumers would stop believing?
People often assume that more collagen automatically means better results.
In reality, the research suggests benefits tend to plateau once you're consistently consuming around 5–10g of hydrolysed collagen each day.
Beyond that, you're mostly paying for a larger serving rather than substantially greater benefits.
08One thing
If you could leave readers with one thing to understand about collagen, what would it be?
Most brands compete on molecular weight: higher doses, smaller molecules. And yes, those things help with absorption. But getting collagen into your bloodstream is only half the battle.
What matters is whether the peptide speaks your skin’s language. Specific-sequenced collagen peptides are cut to carry one message: rebuild skin. Not your muscle, not your gut, your skin. That precision is what makes the difference, and it only comes from proper hydrolysis technology.
