What does the study really show?
A finding makes more sense when you know what was tested and how. Start with these checks.
- Check the exact compound
- Similar names can refer to different forms. Match the compound to the one in the study.
- Look at the study
- Was it tested in cells, animals, or people? Check what was measured and for how long.
- Read the source
- Open the original paper or report. Look for limits, corrections, and findings that did not support the claim.
