The Claim
In laying hens, dietary supplementation with gamma-linolenic acid (GLA) increases total n-6 highly unsaturated fatty acids (HUFA) in egg yolk by 17% compared to linoleic acid (LA), with elevated levels of dihomo-gamma-linolenic acid (DGLA) and arachidonic acid (ARA), suggesting that GLA bypasses a rate-limiting desaturation step in the n-6 HUFA biosynthesis pathway.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Feeding hens a special fat called gamma-linolenic acid (GLA) boosts certain healthy fats in their eggs more than another fat called linoleic acid (LA), and it might skip a slow step in the process — meaning more of the good stuff ends up in the yolk.

In laying hens, dietary gamma-linolenic acid (GLA) increases total n-6 highly unsaturated fatty acids (HUFA) in egg yolk by 17% compared to linoleic acid (LA), with higher levels of dihomo-gamma-linolenic acid (DGLA) and arachidonic acid (ARA), indicating GLA bypasses a rate-limiting desaturation step in n-6 HUFA synthesis.
What the research says
1 studyThe study shows that feeding hens oil rich in GLA boosts beneficial n-6 fats in egg yolks more than LA oil, which supports the idea that GLA is more efficiently used by the hen’s body.
