How we grade: the Haus Verdict

Longevity is loud. Every week brings a new supplement, scan or protocol that promises more years. Most of it is noise. Our job is to sort it, so you can spend your time and money on what actually helps.

Three answers

Every product, claim or trend we cover ends with one verdict.

• Worth it. Good evidence and a fair price.
• Depends. It works for some people or situations. We say who.
• Skip. The evidence is weak or the price is not justified. We say why.

An evidence grade

Claims also get a letter grade for the strength of the evidence behind them.

• A. Strong human trials.
• B. Some human evidence.
• C. Early or mixed results.
• D. Animal studies, hype or nothing.

Our rules

• Every claim links to its source.
• Verdicts are never paid. Affiliate links and sponsors are always labeled.
• If we get something wrong, we correct it in public.
