Evidence Based Longevity (EBL)Check what I take

Where to begin, for patients

A site for asking better questions.

EBL reads the human trials behind supplements, medications and devices, and says how strong that evidence is. It does not tell you what to take. Here is how to use it before your next appointment.

Four steps

From a letter to a conversation.

  1. What a letter means.

    Each letter, A to D, is for one use, not for a product. It says how strong the human trial evidence is for that use. How grades work has the rules, and Research basics explains which studies count, in everyday words.

  2. What you take, looked up.

    Find it under Supplements or Medications, or in the graded index. Each record shows the trials, the doses they used, who was in them and how long they ran.

  3. Your whole list, checked together.

    The Medication and Supplement Check asks seven questions and checks your medications, supplements and conditions against EBL's records. Every finding shows what it rests on. What you type into the check and the discussion sheet stays in your browser. It is not sent to EBL.

  4. One page for your appointment.

    The Physician Discussion Sheet prints one page with the grades, the trial doses and the PMIDs PubMed ID: the permanent number the US National Library of Medicine gives a published paper. Each one links to that paper's record on PubMed., sized for a short visit. Every decision on it stays with you and your clinician.

What this site will not do

A grade is about the trials, not about you.

EBL does not diagnose, and it does not tell anyone to start, stop or change a treatment. A letter describes average results in the people a trial enrolled. You may respond differently, which is why a grade is confidence, not a promise.

If a supplement or device may be harming you, Safety and reporting lists the warning signs and how to report a problem to the FDA. In an emergency, call 911.

The most useful question: what did the trials actually show?

Grades are set from the published evidence. Educational use only, not medical advice.
