Our sources
Good questions deserve clear sources. Here is how research becomes a Forty to Sixty story.


Start with the original research
Our source list begins with original peer-reviewed studies, public-health agencies and professional guidelines. CDC, NIH, ACOG and The Menopause Society are among the organizations we consult.
A headline or social post can raise a question. The underlying research is where we look for the answer.

Look beyond the headline
Our publishing standard is to check who took part in a study, what the researchers measured, how long they followed participants and what limitations they reported. A result in one group is not automatically an answer for everyone.
When findings are mixed or the evidence is limited, the story should say so.

Keep the trail visible
- Find: Locate the original study, guideline or public-health source.
- Check: Read the source and compare it with every factual statement in the draft.
- Explain: Use plain language and keep the uncertainty attached to the finding.
- Cite: Add a linked footnote and retrieval date so readers can follow the trail.
- Update: Recheck sources when a story is revised and correct errors openly.

Information for your next conversation
Forty to Sixty provides education, not individual medical advice. A research article cannot know your health history. Bring questions about symptoms, medication, hormone therapy or supplements to your clinician.
