Why there's vitamin C in our collagen

The body can't form collagen without vitamin C: it's the cofactor for the enzymes that stabilise each new collagen molecule.* Why that puts 100 mg of it in every scoop of ours.

Read the panel on a collagen powder and there's a question worth asking: is there any vitamin C in it?

Not as a bonus ingredient. Here's why it's in every scoop of ours.

Collagen you swallow doesn't arrive as collagen

It's digested like any protein, into shorter peptides and amino acids. The body makes its own collagen, and the step that stabilises each new collagen molecule is enzymatic: vitamin C is the cofactor for those enzymes, so the body can't form collagen without it.*

Not "work better with". Cannot work without. It isn't an optional booster — it's a required part of the reaction, and it's in every physiology textbook rather than in anybody's marketing.

Why put it in the scoop

Most people get vitamin C from food, and if you eat reasonably you're almost certainly getting enough — this isn't a scare story. But it's the one link in the chain a formula can include on purpose, it costs very little, and it puts collagen peptides and the vitamin C collagen formation needs in the same scoop.

Per 10 g scoop

Fish collagen peptide
4,500 mg
Vitamin C
100 mg
Acerola cherry extract
100 mg

Two separate entries, not one figure. The acerola is listed at its own amount rather than counted towards the 100 mg of vitamin C.

Why acerola as well

Acerola is a small red cherry from a shrub that happens to be one of the densest natural sources of vitamin C there is. It's in the formula alongside the vitamin C rather than instead of it, so the vitamin C in a scoop turns up both as the isolated vitamin and in the form it arrives in when it comes from food. Two entries on the panel, 100 mg each.

What this doesn't mean

It doesn't mean vitamin C does anything dramatic on its own, and it doesn't mean more of it is better — if you're already getting plenty, the extra isn't the hero of the story. And it doesn't mean that swallowing collagen sends collagen to your face — your body decides where the material goes. A formula can put the peptides and the vitamin C in the same scoop, at doses printed on the label. It can't aim, and we won't claim it does.

This is the formula argument, and it's the only one

Most of what's in this range isn't here because we invented it. It's here because it's chosen for women 40+ — that's the whole basis on which the four products were chosen, and we'd rather say so than dress each one up as a breakthrough.

The collagen is the one place where a formulation decision is the story: 4,500 mg of peptides, and the vitamin C collagen formation needs, in one scoop.

Check the panel

Go and read the panel on whatever you're taking now, and look for vitamin C on it.

Marine Collagen + Vitamin C puts 4,500 mg of peptide and 100 mg of vitamin C — 111% of the daily value — in the same 10 g scoop, thirty scoops to a tub, at $1.33 a day. The full chain — swallow it, digest it, and the step where vitamin C comes in — is set out step by step on how it works, and if you're wondering why it's a scoop and not a capsule, that's the other half of the argument.
