Dietary supplements are a big business. The industry made almost US$39 billion in revenue in 2022, and with very little regulation and oversight, it stands to keep growing.
The marketing of dietary supplements has been quite effective, with 77% of Americans reporting feeling that the supplement industry is trustworthy. The idea of taking your health into your own hands is appealing, and supplements are popular with athletes, parents, and people trying to recover more quickly from a cold or flu, just to name a few.
