According to Gram Research analysis, dietary supplement use in the United States is increasing, with older adults using vitamins, minerals, and other supplements at higher rates than younger Americans. A 2026 JAMA study found that this upward trend in supplement use reflects a significant shift in how Americans approach their health, though the research documents the trend without proving whether supplements improve health outcomes.
A new study published in JAMA shows that more people in the United States are taking dietary supplements like vitamins and minerals, with older adults leading the trend. Researchers analyzed data about supplement use across the country and found that this habit is becoming increasingly common. The findings help us understand how many Americans rely on these products and which age groups are most likely to use them. This information is important for doctors, health officials, and anyone thinking about whether supplements might be right for them.
Key Statistics
A 2026 JAMA research article found that dietary supplement use is increasing across the United States, with older adults showing particularly high rates of supplement consumption compared to younger age groups.
According to research reviewed by Gram, the trend toward greater supplement use in America appears to be sustained over recent years, indicating a lasting change in American health behaviors rather than a temporary phenomenon.
The Quick Take
- What they studied: How many Americans take dietary supplements like vitamins, minerals, and herbs, and whether this number is going up or down over time
- Who participated: The study analyzed data from a large group of Americans across different ages, with a focus on comparing younger and older adults
- Key finding: Dietary supplement use in the United States is increasing, with older adults using them more frequently than younger people
- What it means for you: If you’re considering taking supplements, know that you’re part of a growing trend. However, talk to your doctor first to make sure any supplement is safe for you and won’t interfere with medications you’re taking
The Research Details
Researchers looked at data about supplement use across the United States to understand how common this practice is and how it’s changing over time. They examined information from large surveys that track what Americans eat and what health products they use. By comparing data from different years, they could see whether more people are taking supplements now than in the past. The study focused especially on older adults because preliminary observations suggested this group might be using supplements more than others.
Understanding supplement use patterns helps doctors and public health officials know what their patients and communities are doing. When health professionals understand these trends, they can better advise people about whether supplements are helpful, which ones are safe, and how they might interact with medications. This information also helps researchers decide what topics need more study.
This research was published in JAMA, one of the most respected medical journals in the world. The study analyzed real-world data about American supplement use, which makes the findings relevant to actual people’s health choices. However, the study describes trends rather than proving that supplements cause specific health benefits or problems.
What the Results Show
The research shows that dietary supplement use is becoming more common across the United States. Older adults are using supplements at higher rates than younger adults, suggesting that age is an important factor in supplement use decisions. The upward trend in supplement use appears consistent across recent years, indicating this is a sustained change in American health habits rather than a temporary spike. This growing use of supplements reflects how many Americans are trying to take charge of their health through these products.
The study likely examined which types of supplements are most popular, such as vitamins, minerals, or herbal products. Understanding these patterns helps identify which supplements Americans trust most and which age groups prefer certain types. The research may also reveal differences between men and women, or between different regions of the country.
Earlier research has tracked supplement use over many years, and this new study adds to that picture by showing the trend continues upward. Previous studies established that supplement use was already common in America, and this research confirms that the practice is becoming even more widespread, particularly among seniors.
The study describes what’s happening with supplement use but doesn’t prove whether supplements actually help people feel better or live longer. The research shows trends in the population but may not capture everyone’s supplement use accurately, since some people might not report it. Additionally, the study doesn’t examine why people choose to take supplements or whether they’re taking them safely.
The Bottom Line
If you’re thinking about taking a dietary supplement, talk to your doctor first. This is especially important if you take other medications, since supplements can sometimes interact with them. Your doctor can help you decide if a supplement is right for you and recommend safe, effective options. (Confidence level: Strong recommendation based on standard medical practice)
Older adults should pay special attention to this research since they’re the group most likely to use supplements. Anyone taking medications should care about this topic because supplements can affect how medicines work. People interested in preventive health and understanding American health trends should also find this relevant.
If you start taking a supplement, give it at least 4-8 weeks to see if it makes a difference, though some supplements take longer. Talk to your doctor about what timeline makes sense for the specific supplement you’re considering.
