https://en.wikipedia.org/wiki/Nutraceutical

Nutraceutical is a marketing term used to imply a pharmaceutical effect from plant extracts, compounds, or food products that are claimed to influence health outcomes, typically as dietary supplements.[1]

In the United States, nutraceuticals are regulated by the Food and Drug Administration (FDA) as foods, dietary supplements or food ingredients, depending on the ingredients included and marketing claims.[2][3] Regulatory treatment varies by jurisdiction, and the term has no uniform legal definition internationally.[4][5]
