Omega-6 oil may boost insulin sensitivity in At-Risk adults
NCT ID NCT07287514
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether taking a daily oil rich in linoleic acid (a type of omega-6 fat) for 8 weeks can improve insulin resistance in adults aged 20-60 who have this condition plus at least one other cardiometabolic risk factor (like abdominal obesity or high blood pressure). Participants will be randomly assigned to receive either the linoleic acid oil or a control blended oil, while keeping their usual diet. The main goal is to see if the oil reduces insulin resistance, which could help manage metabolic disease.
