24zdorovie: health without myths
A bilingual health site with source-cited explainers and 25 calculators and self-tests that run right in your browser.
What it is
24zdorovie is a health site in English and Russian built around one question: what's actually proven, and what's just being sold to you. The home page lists 137 articles across 12 topics — nutrition, sleep, heart, gut, women's health, longevity, mental health and more — alongside 25 calculators and self-tests and a small supplement guide. This is one of our own projects.
Why we picked it
The calculators aren't made-up scales. Each one uses a published formula or a validated questionnaire, and the source is named right under the tool: Mifflin-St Jeor for calories, Morgan Levine's PhenoAge for biological age, SCORE2 for cardiovascular risk, FINDRISC for type 2 diabetes risk, PHQ-9 and GAD-7 for mood and anxiety. Every tool also tells you what it can't do, and the site says your numbers stay in the browser rather than going to a server.
The biological age calculator shows the approach well. It works out PhenoAge from nine markers on an ordinary blood test, then explains plainly that the result is a risk score dressed up as an age, not a measurement of your cells. It also shows which marker pushes the number most. The supplement guide is small for now — creatine, vitamin C, zinc, calcium and coenzyme Q10 — but each card covers the working dose, food sources, the evidence and the common myths.
Where to start
- Open Tools and pick a topic: sleep, heart, weight, women's health.
- Try the biological age calculator, from blood work or in the lifestyle mode.
- Read the new piece on depression, then take the PHQ-9 if it feels relevant.
- Check the supplement guide before buying your next tub of anything.
- If you like email, there's a weekly digest that comes with a free PDF checklist.
Who it's for
People with a specific health question who are tired of marketing claims. Anyone who wants a quick number — calorie targets, heart rate zones, a sensible bedtime — with the formula shown. And readers who switch between English and Russian, since every article and tool exists in both.
Quick answers
Is it free? Yes. Articles, calculators and tests are open with no sign-up.
Does it replace a doctor? No. It's information and tools; the site says plainly that it doesn't diagnose and isn't a substitute for a consultation.
Is the English version complete? Yes, it mirrors the Russian one, with the same sections and tools.
