Gamma-linoleic acid (GLA) is an omega-6 polyunsaturated fatty acid made in the body from linolenic acid, an essential fatty acid (EFA).

Gamma-linoleic acid is found naturally in fish, animal organs such as liver, and certain plant seed oils.

Gamma-linoleic acid (GLA) is an omega-6 polyunsaturated fatty acid made in the body from linolenic acid, an essential fatty acid (EFA).

In animal studies gamma-linoleic acid has been shown to reduce certain inflammations and reduce joint tissue injury. Human studies showed similar findings in its anti-inflammatory effects.

Arachidonic acid is a 20:4(delta5,8,11,14) derivative fatty acid from linoleic acid. Linoleic and linolenic acids are "essential fatty acids" for mammals and they must be consumed from plant sources. Once consumed, linoleic acid may be converted to other polyunsaturated acids, particularly gamma-linoleic acid, eicosatrienoate and arachidonic acid (or eicosatetranoate) which can be only from linoleic acid.
