MedicalResearch.com Interview with: [caption id="attachment_74329" align="alignleft" width="150"]Chun Sing (Jason) Lam, PhDPostdoctoral Research Fellow Integrative Medicine and Wellness Service Department of Medicine Memorial Sloan Kettering Cancer Center Chun Sing Lam, PhD[/caption] Chun Sing (Jason) Lam, PhD Postdoctoral Research Fellow Integrative Medicine and Wellness Service Department of Medicine Memorial Sloan Kettering Cancer Center MedicalResearch.com: What is the background for this study? What are the main supplements utilized by Americans? Response: Dietary supplement use is very common among U.S. adults, but patterns of use have changed substantially over time. The supplement market has expanded, with many products now marketed for different uses. But long-term national data are limited. In this study, we analyzed 25 years of nationally representative data from the National Health and Nutrition Examination Survey, from 1999 through August 2023, including 63,442 U.S. adults. Overall supplement use increased from about 51% of U.S. adults in 1999–2000 to about 60% in 2021–2023. Use of four or more supplements also increased, from 8.8% to 15%. One notable finding was that multivitamin/multimineral use declined modestly while use of individual vitamins, minerals, and specialty supplements increased. One important finding was the increase among older adults. Supplement use among adults aged 65 years and older increased from about 62% to 78%, which was the largest increase among demographic subgroups. Notable increases were seen for vitamin D, zinc, vitamin K, biotin, vitamin B12, and omega-3. Emerging trends were also seen for non-vitamin non-mineral supplements such as turmeric/curcumin, probiotics/prebiotics, collagen, elderberry, ashwagandha, and hyaluronic acid. These trends likely reflect growing consumer interest in immune support, gut health, and skin and joint health.

Cod liver oil has moved from grandmother's remedy to clinical research subject, with recent studies continuing to validate its role in cardiovascular protection and immune function. Unlike standard fish oil, cod liver oil delivers a unique combination of omega-3 fatty acids—EPA and DHA—alongside naturally occurring vitamins A and D, making it especially relevant for populations at risk of nutrient deficiencies or those seeking consolidated supplementation. The science is compelling: a three-year interventional trial published in 2021 examined 870 patients at cardiovascular risk and found that daily cod liver oil supplementation reduced the incidence of myocardial infarction. Omega-3 fatty acids from marine sources have also been shown to reduce triglycerides by 15–30% and raise HDL cholesterol in multiple dose-response meta-analyses. Vitamin D, abundant in cod liver oil, continues to draw attention for its role in immune modulation, bone health, and potentially reducing the risk of acute respiratory infections. But not all cod liver oil is created equal. Extraction methods, sourcing, oxidation control, third-party testing, and omega-3 potency vary dramatically across brands. This ranked comparison evaluates real products available in 2026, prioritizing verifiable omega-3 content, independent lab certification, freshness protocols, and sustainability practices.

MedicalResearch.com Interview with: [caption id="attachment_59544" align="alignleft" width="150"]Ariela Orkaby, MD, MPH Geriatrics & Preventive Cardiology Associate Epidemiologist Division of Aging, Brigham and Women's Hospital  Assistant Professor of Medicine, Harvard Medical School Dr. Orkaby[/caption] Ariela Orkaby, MD, MPH Geriatrics & Preventive Cardiology Associate Epidemiologist Division of Aging, Brigham and Women's Hospital Assistant Professor of Medicine, Harvard Medical School MedicalResearch.com: What is the background for this study? Response: As the population is living longer, there is increased risk of frailty and vulnerability. Frailty is defined as reduced physiological reserve and decreased ability to cope with even an acute stress. Up to half of adults over the age of 85 are living with frailty and preventative measures are greatly needed. We tested the effect of vitamin D and marine omega-3 fatty acid supplementation on the risk of developing frailty in healthy older adults in the US enrolled in the VITamin D and OmegA-3 TriaL (VITAL) trial.
