What is Arachidonic Acid (Omega-6)?

An omega-6 fatty acid the body makes from linoleic acid and uses in inflammation signaling.

Arachidonic acid is an omega-6 fatty acid that the body builds from linoleic acid and uses as a starting point for signals involved in inflammation and clotting. Despite that role, large pooled studies found that higher blood levels of arachidonic acid were not associated with higher cardiovascular risk and were sometimes linked with slightly lower risk. This is an advanced fatty-acid marker reported within a specialized panel rather than a routine blood test.
