The Claim

In laying hens, dietary supplementation with high-stearidonic acid (SDA) oil increases total n-3 highly unsaturated fatty acids (HUFA) in egg yolk by 39% compared to high-alpha-linolenic acid (ALA) oil, with significantly higher levels of eicosapentaenoic acid (EPA), docosapentaenoic acid (DPA), and docosahexaenoic acid (DHA), due to more efficient metabolic conversion that bypasses the delta-6 desaturase step.

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

If you feed laying hens oil rich in a fat called SDA, their eggs end up with way more of the good omega-3 fats—like EPA, DPA, and DHA—compared to feeding them another plant-based omega-3 oil. This happens because SDA skips a slow step in the hen’s body that usually holds back omega-3 production.

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 SDA boosts healthy fats in eggs more than ALA oil, which matches the main idea of the claim.
