Roll Call does not check drug interactions or assess personal safety.
A monounsaturated fatty acid abundant in olive oil and other plant and animal fats, sometimes used in supplements as a fat source or as a carrier oil in softgels.
Why it’s used
Included as a fatty-acid ingredient or oil base, and sometimes highlighted because of its presence in diets studied for cardiovascular health.
What the evidence says
Evidence linking monounsaturated fat intake to cardiovascular markers comes largely from studies of whole dietary patterns, such as Mediterranean-diet research, rather than trials of isolated oleic acid supplementation. There is no NIH ODS fact sheet treating it as a standalone supplement ingredient.
