Key Points:

Supplement use among U.S. adults increased from 51% in 1999 to 60% in 2023, with a notable rise in people taking four or more supplements, doubling from 9% to 15%.
There has been a shift from general multivitamin use to more personalized, targeted supplements, with significant growth in vitamin D (from 5% to 29%) and omega-3 supplements (from 2% to 14%) over 25 years.
The largest increase in supplement consumption occurred among adults aged 65 and older, with nearly 78% reporting supplement use by 2023.
The dietary supplement market, valued at nearly $200 billion in 2024, is projected to double by 2033, raising concerns about safety and efficacy since supplements are not subject to FDA premarket approval like pharmaceuticals.
Researchers highlight the importance of monitoring supplement usage trends and conducting further studies on their safety, effectiveness, and varying impacts on different populations to inform public health guidance.
