Summary

Planet Money hosts attempt to create their own supplement to expose the industry's lax regulations and low barriers to entry. They interview experts who reveal that supplements don't need FDA approval for safety or efficacy, leading to issues like mislabeled ingredients and unproven health claims. Despite these risks, the episode concludes that Americans continue buying supplements largely due to the powerful placebo effect and a cultural desire for quick health fixes.
