The Claim

In laying hens, dietary stearidonic acid (SDA) increases the efficiency of n-3 highly unsaturated fatty acid (HUFA) synthesis and transfer to egg yolk by 43% compared to alpha-linolenic acid (ALA), as measured by the ratio of yolk HUFA to dietary intake, due to more direct metabolic conversion.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

How it works
1 study reviewed
In plain English

Feeding hens a certain type of fat called stearidonic acid helps their bodies make more healthy omega-3s in egg yolks—43% better than another fat called ALA—because it’s easier for their bodies to 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 SDA led to more healthy fats in eggs than oil with ALA, which supports the idea that SDA works better. But it doesn’t prove the exact 43% boost mentioned in the claim.
