How answers work
RegenEvidence answers questions about stem cells, PRP, exosomes and other regenerative treatments by reading published research and official health pages, then summing up what they show in plain language.
Where answers come from
Published research
Reviews and studies listed on PubMed, the U.S. National Library of Medicine's index of medical research.
Registered trials
Entries on ClinicalTrials.gov. They say what a study is testing, not its results, so answers use them only to describe research under way.
Official health pages
Pages from the FDA, the European Medicines Agency, MedlinePlus, the National Cancer Institute and the National Institutes of Health, kept in our own library and checked before use.
Answers never draw on clinic websites, ads or company pages.
How each answer is checked
- Every statement cites the source it comes from, numbered in the text.
- Each citation shows the exact words it relies on, and those words are checked against the source before the answer is shown. A statement whose source doesn't say it is dropped.
- When there is no good research in people, the answer says so.
- Answers never name a clinic or doctor, give a price or dose, or tell anyone to start or stop a treatment.
How strong is the evidence?
Each answer rates the research behind its main finding, whichever way it points: strong evidence can show that a treatment does not help.
- Strong evidence
- Several good-quality studies in people agree.
- Moderate evidence
- Some good studies in people, but questions remain.
- Limited evidence
- Few or small studies in people, so results could change.
- Insufficient evidence
- Too little research in people to say.
Your questions stay private
Your question goes to our AI service to write the answer. The services that search and rank sources get only the medical search terms, never your question. Questions never appear in links, page titles or analytics. See the Privacy Policy and Your data.
