#393 ‒ AMA #85: A guide to medications and supplements: determining what to take, what to skip, and how to know if they're working for you

Peter Attia provides a framework for evaluating medications and supplements. He emphasizes that the first step is to clearly define the health problem, rather than jumping to a 'good' or 'bad' label. The intended purpose of an intervention determines how much evidence is needed and what risks are acceptable. He examines how baseline risk influences the true benefit of a therapy and why relative risk statistics can mislead.

Canon

Define the Problem Before Prescribing1:45
Peter stresses that the first step in considering any medication or supplement is to accurately define the health problem, not to label the intervention as inherently good or bad.
Evidence Requirements Depend on the Goal5:00
Peter explains that the intended purpose of a drug or supplement—whether for disease prevention, symptom relief, or performance enhancement—dictates the standard of evidence needed and the risk tolerance.
Absolute Risk vs. Relative Risk: Context Is Everything
Peter warns that relative risk reductions can be misleading without knowledge of the absolute baseline risk, which determines the real-world benefit.
Mechanistic Logic Alone Is Insufficient
Peter cautions against taking a supplement or drug solely because its proposed mechanism seems plausible; human biology is too complex for that reasoning to predict real outcomes.

Highlights

Only a Small Group of OTC Supplements Make the Cut
Peter believes that very few over-the-counter supplements offer a favorable risk-reward trade-off when judged by rigorous standards.
