What this site is
Every morning we gather new research on aging and healthy living: published studies, early results, clinical trials and FDA news. We explain each one in plain English and link to the original.
We also collect what named experts say, always with a link to where they said it, and we compare tests, products and clinics.
Once a week we send a free email with the week's most useful new research, explained the same way.
We are not doctors, and we don't judge what works. We gather and explain. Where the research is thin, we say so.
How to read a research stage
Every treatment has a stage from 1 to 4. It shows how far testing in people has gone, not whether something will work for you. It's worked out automatically from PubMed, ClinicalTrials.gov and FDA records every morning, and each page says which rule placed it.
- 4Stage 4: Widely recommended. Approved by the FDA for that use, or recommended in a major health guideline. We link the approval or guideline.
- 3Stage 3: Large studies in people. At least one large (phase 3) trial in people, or at least five large randomized trials, has been published.
- 2Stage 2: Small studies in people. There is at least one trial in people, published or registered, but no large ones yet.
- 1Stage 1: Tested in animals only. Only studies in animals or cells have been found so far.
A product never gets its own stage. Product pages show the stage of each ingredient, which describes research on that ingredient, not proof that the product works.
Talk to your doctor first
Before you start, stop or change any treatment or supplement, talk to your doctor or pharmacist. Some supplements interact with medicines, and what suits one person may not suit another.
