#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.
