An oil pressed from macadamia nuts, high in monounsaturated fatty acids, used in supplements as a fat source or carrier oil.

Why it’s used

Taken as a source of monounsaturated fat, sometimes marketed for skin, hair, or general cardiovascular wellness claims.

What the evidence says

Diets higher in monounsaturated fats generally, including from nut oils, have been studied for cardiovascular markers, but macadamia oil as an isolated supplement ingredient has not been separately tested in controlled human trials for these outcomes.

Context

Most relevant research examines whole macadamia nuts or general monounsaturated fat intake within a dietary pattern, not concentrated oil taken as a standalone supplement.
