Supplement
Arachidonic acid is an omega-6 fatty acid found in cell membranes throughout the body, where it serves as a building block for signaling molecules involved in inflammation and muscle repair. People mostly look at it for body composition and exercise performance, and the evidence is limited: in one small study, anaerobic capacity improved, while body fat showed no clear difference. That research involved only 31 people, so it says little about how results might apply more broadly.
