Nutraceuticals and dietary supplements: Disparities in usage and potential for harm

Background: The use of nutraceuticals and dietary supplements has a complex history. Aim: This work seeks to discuss the current state of nutraceuticals and dietary supplements, with a particular focus on the ambiguity of these terms, their current usage, potential harms, roles within the healthcare system, and associated disparities. Methods: This work reviews recent literature spanning the history of nutraceuticals and expands upon recommendations made by previous authors. Results: While a substantial portion of the United States population consumes these substances, their safety profiles are rarely well characterized. Taking a broad definition of these terms paints a picture of harmless use by a population that is middle-aged, educated, and white. However, focusing on specific substances reveals concerning disparities in race, ethnicity, income, physical health, and health literacy. This is of particular concern when looking at the side effects of these supplements both in isolation and due to drug-supplement interactions. Conclusions: In this work, the authors build upon the recommendations of others to propose ways in which physicians and healthcare systems can work to reduce the disproportionate harms of these substances on historically marginalized groups.
