How we decide what to sell

Three questions decide what gets on this shelf.

Every product here is made for women 40+, with every active printed at its dose. This is how we decide what goes on the shelf — and where the one formula difference in the range, the vitamin C in the collagen scoop, came from.

Three questions, in this order

Every product here had to answer all three. Most of what we looked at answered one, and one isn't enough.

  • Is it chosen for this stage of life?

    Every product on the shelf is made for women 40+. If it would sit just as well on a shelf for anybody, it doesn't go on ours.

  • Is it a job for a supplement?

    Some things are a job for a cream, or for a doctor. We only make what a daily scoop or capsule can honestly be: a nutrient at a stated dose, in a form that fits a routine. We don't claim more than that for any of it.

  • Does the formula carry what it needs?

    Collagen formation needs vitamin C.* So the collagen doesn't come alone: every scoop carries 100 mg of vitamin C — 111% of the daily value — alongside the 4,500 mg of peptides.

The formula difference

4,500 mg of collagen, plus its cofactor

The body can't form collagen without vitamin C: it's the cofactor for the enzymes that stabilise each new collagen molecule.*

So every 10 g scoop carries 100 mg of vitamin C — 111% of the daily value — alongside 100 mg of acerola cherry and 4,500 mg of marine collagen peptides. It is the one formula story in the range, and it is why we point most people at the collagen first.

Three pages, depending on what you want to check

This page is the overview. The detail lives in three places, and none of them needs the others read first.

Still not sure which one is yours?

Four questions, about two minutes, and a straight answer about which of these is worth your money — including the one where the answer is a single product rather than three.
