Inside the book
A changed biomarker is not a longer human life. The evidence-tier layer keeps the study setting and the actual outcome visible, so promising research cannot quietly become a promise to you.

Educational and non-prescriptive. Research exposures are descriptions of studies, never reader doses. Safety accompanies each item; care decisions belong with a qualified clinician.
The method, in plain view
A grade belongs to a defined claim: the form or route, outcome and studied population matter. Read the explanation beside the letter.
Tested in / What it’s been shown to do: the cards distinguish humans, animals and cells, and separate mortality, function, biomarkers and mechanisms. Mouse-only evidence records stay ungraded.
Missing research is not the same as evidence of no benefit. E does not mean “we do not know.”
Research and its limits stay together, including what has not been established. A grade is not a treatment recommendation or a guarantee of personal benefit.
No. A better blood result does not by itself establish longer life. Read the grade alongside the study setting and the outcome that was actually measured.
Yes. Grades belong to specific claims and outcomes. Evidence for one outcome does not automatically support a different claim, and a combination needs its own evidence.
No. A benefit grade does not remove interactions, exclusions or monitoring needs. Short-term tolerability also provides limited information about long-term use.
