Consumers Returned to Pre-Pandemic Supplement Usage in 2021, ConsumerLab Survey Reveals
White Plains, New York, February 24, 2022 —A survey of 8,049 people who use dietary supplements shows many supplements that declined in use in 2020 began bouncing back in 2021, such as magnesium (+2.4 percentage points), and CoQ10 (+2.7 pts). In fact, 25 of the 30 most popular supplements rose in usage in 2021 in contrast to 2020 when two-thirds declined, suggesting a return to pre-pandemic supplement usage.

Supplements that experienced the greatest growth in popularity in 2021 were iron (+4.2 pts), fiber (such as psyllium) (+4.1 pts), and melatonin (+3.9 pts). Supplements that experienced large increases in popularity in 2020 due to their promotion to prevent or treat COVID-19, such as zinc, vitamin C, vitamin D, quercetin, and elderberry were largely flat.
