Research Notes

People sometimes ask how three writers without clinical training decide what to say about creatine, fasting windows or gum disease. Fair question. Here is the honest answer, notebook style.

Where we look first

1. Public health bodies. National health services, government health agencies and international health organizations publish guidance written for the public. That is our starting point for anything to do with activity levels, diet or common conditions.
2. Professional associations. Groups representing dentists, dietitians, pharmacists and sports professionals often publish patient-facing advice. We use it to check that our everyday version matches what the profession tells its own patients.
3. Labels and official leaflets. For a supplement, medicine or device, the packaging and the leaflet inside say what the maker states it is for, who should avoid it and what to watch for. We read those rather than marketing pages.
4. Manufacturer help pages for trackers and apps, when the question is about how a feature works rather than whether it is good for you.

What we try not to lean on

Forum threads, influencer clips and single headline-grabbing claims can point to a question worth asking, but they never become the answer. If a claim only appears in places like that, it does not make it into a guide.

Handling doubt

Plenty of everyday health questions have no tidy answer. When sources disagree, or the evidence is thin, we say that in the article instead of picking the most exciting version. Phrases like "may help some people" or "the picture is mixed" are there deliberately. When the safe course is unclear, the guide points you to someone who can weigh your circumstances.

Numbers

We do not invent figures, percentages or study results. Where a number appears, such as a common step target, it is one widely used in public guidance, and we explain it as a rough marker rather than a rule. If we cannot trace a number back to a sensible source, we leave it out.

Keeping notes current

Guidance moves. When we revisit a topic, we check it against current sources and update the page date. Spot something stale? Our corrections promise explains what happens next.
