This page explains how articles on Fortylight get written, graded, and updated.
Who writes this
Every article is written by Nina Halvorsen, described on the about page. Nina is not a physician, dietitian, or licensed health professional, and none of what she writes should be read as a substitute for one.
How evidence gets graded
Most articles carry at least one Evidence Strip: a short box stating how many studies exist, how many people they covered, and who funded them, followed by a grade.
| Grade | What it means |
|---|---|
| Strong | At least one randomized controlled trial with a result that held up. |
| Mixed | Solid mechanism or physiology, but the evidence for real-world impact is observational, self-reported, or inconsistent. |
| Thin | A handful of small studies, often with real limitations. |
| Anecdotal | Reported experience, no controlled study behind it yet. |
Nothing on this site is graded “strong” without a randomized controlled trial behind it. That grade is rare, on purpose.
Corrections
Articles carry a visible “updated” date whenever the content changes in a way that matters — a new study, a correction, a changed recommendation. If you think something here is wrong, get in touch and it will be checked.
How offers get chosen
The product has to fit the woman this site is written for, not the other way around. An offer that pays well but doesn’t hold up — a generic probiotic, a product whose landing page makes a treatment claim, anything without delivery to the US, Canada, and the UK — gets turned down regardless of commission. Financial relationships are disclosed in plain text before the first affiliate link on any page; see the disclosure page for the exact wording used sitewide.
