Americans are turning to supplements in record numbers, with a recent study revealing a significant increase in their use over the past 25 years. The research, which analyzed data from over 63,000 adults, found that supplement use grew from 51% of the US adult population to 60%.
The largest rise was seen in adults 65 and older, with supplement use increasing from 62% to 78%. The study also found that supplement use was more common in women, people with higher incomes or education levels, and those with insurance. Meanwhile, multivitamin use decreased from 35% to 31%.
The study identified a significant increase in the intake of vitamins and minerals outside of multivitamins, with some of the largest rises seen in vitamin D, zinc, magnesium, vitamin B12, and turmeric. Other emerging supplements include ashwagandha, elderberry, collagen, hyaluronic acid, probiotics, and prebiotics. The post-pandemic period saw a surge in immune support-based products, such as zinc and vitamin D.
The rise in supplement use aligns with the growing interest in the longevity movement, as people seek products tailored to specific health goals, including immune support, inflammation, gut health, skin health, and joint health. However, the study's authors noted that the research does not prove the effectiveness of supplements for these uses.
A registered dietitian nutritionist expressed concerns about the emerging supplement movement, citing the need for more education and guidance from qualified healthcare professionals. She emphasized the importance of choosing high-quality supplements that have undergone third-party testing for safety and quality.
"I wish people were being advised by more doctors and dietitians and less by 'wellness influencers' who are likely not doing the due diligence on the quality and efficacy of the supplements they're promoting," she said. She recommended starting with a multivitamin as a foundation to bridge nutrient gaps, particularly for people on certain medications that may affect nutrient intake.
The nutritionist also highlighted the benefits of certain supplements, such as probiotics, magnesium, and vitamin D3, and recommended elderberry for boosting the immune system. However, she cautioned against taking supplements that haven't undergone rigorous testing and warned against the unregulated market.
"My real concern is the unregulated market," she said. "I'm extremely picky about what I take and what I recommend to my family and clients." Her advice is to look for products that have undergone third-party testing for safety and quality, particularly for protein powders and supplements with multiple ingredients.
