What is actually proven about the female body after forty?

A great deal is claimed and little is proven. This archive puts the level of evidence next to every study — from a trial in a dish to a meta-analysis of thousands of participants — so you can see for yourself whether a promise rests on anything.

and growing

Every study links back to the original publication, with the date it was checked. Nothing disappears here: what you save stays findable.

What you get

The verdict is free. You pay to read the whole thing.

Nobody should have to pay to find out whether something works. What a subscription buys is the depth: the full write-up of each study, and being told when the evidence changes.

Free for everyone

No account, no payment

  • ✓ The title of every study and what it examined
  • ✓ The level of evidence, from 1 to 5
  • ✓ Whether a manufacturer helped pay for it
  • ✓ The conclusion in three sentences
  • ✓ What it means for you, in one fixed closing line
  • ✓ A link to the original publication
  • ✓ Every article in the knowledge base

Free. Enough to judge a claim, and enough to see that we are not selling you anything.

Why you can trust this

Every study carries the weight of its evidence.

One rule comes before all others: who it was studied in weighs more than how it was studied. A meta-analysis of mouse experiments is still about mice. That distinction is exactly where this market makes its money.

5 · Repeated evidence
Several studies in people combined into one analysis — not one group, not one lucky finding
4 · Large controlled trial
A comparison group, and at least a hundred participants
3 · Small study in people
Enough to suspect something, too little to promise anything
2 · Animal study
Most substances that work in mice do nothing in people
1 · Laboratory
Cells in a dish. Everything starts here, and most of it gets no further

How we work

What we do, and what we will never do.

The promise below is not a line in a template. A nightly check scans every published page for outbound links to sellers and for the usual affiliate parameters. If it finds one, that is a red light on the dashboard — not a warning that scrolls away.

Every claim has a source

Under every statement is where it came from: the publication on PubMed, with its year, its journal and the date we last checked it.

No advice, no doses

We describe what exists; we prescribe nothing. No doses, no personal prognosis, no reading of your results. That is what your doctor is for.

Nothing for sale, ever

No advertising, no affiliate links, no sponsored content, no products. If a manufacturer helped fund a study, that is on the page — as a fact, not as a verdict.

Six languages, one archive

English here, with Dutch, German, French, Spanish and Italian alongside it. The same studies, the same grades, the original always within reach.
