DGLA (Dihomo-gamma-linolenic acid)
Also known as DGLA, Dihomo-gamma-linolenic acid, 20:3 n-6
Dihomo-gamma-linolenic acid (DGLA) is a long-chain omega-6 fat the body makes from GLA. It is notable because it produces anti-inflammatory signaling molecules, in contrast to the pro-inflammatory products of its relative arachidonic acid.
Why it matters
What it does in your body
- Source of anti-inflammatory signaling molecules
- Intermediate in omega-6 metabolism
- Competes with arachidonic acid to temper inflammation
- Supports skin health
Intake guidance
How much you need
There is no intake target for DGLA, because the body makes it from GLA and linoleic acid rather than obtaining it directly from common foods. Its levels are influenced more by internal metabolism than by diet.
What affects it
What affects your intake
Body's own production
DGLA is synthesized from GLA, so it is not a dietary requirement.
GLA supplements
Taking GLA-rich oils like evening primrose can raise DGLA levels in the body.
Balance with arachidonic acid
DGLA and arachidonic acid compete, with DGLA favoring less inflammation.
In practice
Good to know
Good to know: DGLA is a behind-the-scenes omega-6 that tilts the body toward less inflammation, the friendly counterpart to arachidonic acid. It is not something you eat directly in any meaningful amount; instead, GLA supplements are the usual way to raise it. There is no dietary target to hit.
Where to get it
Best food sources
The bottom line
DGLA is a self-made, anti-inflammatory omega-6 the body builds from GLA. There is no need to get it from food directly.
