The Claim

In laying hens, dietary gamma-linolenic acid (GLA) increases the efficiency of n-6 highly unsaturated fatty acid (HUFA) synthesis and transfer to egg yolk by 16.7% compared to linoleic acid (LA), indicating that GLA bypasses a metabolic bottleneck in the n-6 fatty acid 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.

How it works
1 study reviewed
In plain English

Feeding hens a special fat called gamma-linolenic acid (GLA) helps their bodies make more healthy fats for the egg yolk—16.7% better than another fat called linoleic acid—because GLA skips a slow step in the process.

What the research says

1 study

  1. Study: Effect of oil blends with near equal increases in 18 carbon n-3 and n-6 fatty acids on fatty acid profile of eggs

    The study found that feeding hens oil rich in GLA led to more healthy fats in the egg yolk than oil with LA, which supports the idea that GLA works better because it skips a slow step in the process.
