During 2017–2018, 57.6% of adults aged ≥20 years had taken a dietary supplement within the past 30 days.
The percentage increased with family income: 44.9% among those with family incomes <130% of the FPL, 56.2% among those with family incomes 130%–349% of the federal poverty level (FPL), and 65.7% among those with family incomes ≥350% of the FPL.
The increase with family income was seen for both men and women.
Women were more likely than were men to use a dietary supplement overall (63.8% versus 50.8%) and at each income level.
