The Claim

In laying hens, dietary stearidonic acid (SDA) leads to significantly higher hepatic expression of the fatty acid elongase enzyme ELOV2 compared to diets containing alpha-linolenic acid (ALA), gamma-linolenic acid (GLA), or linoleic acid (LA), indicating that SDA may upregulate a key enzyme involved in long-chain fatty acid synthesis.

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 laying hens a type of fat called stearidonic acid boosts a specific liver enzyme that helps make longer fatty acids more than other fats do.

See the scientific wording

In laying hens, hepatic expression of the fatty acid elongase ELOV2 is significantly higher in those fed stearidonic acid (SDA) compared to those fed alpha-linolenic acid (ALA), gamma-linolenic acid (GLA), or linoleic acid (LA), suggesting SDA upregulates a key enzyme in long-chain fatty acid synthesis.

  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 hens fed stearidonic acid had higher levels of a key fat-making enzyme in their liver compared to those fed other fats, which supports the idea that this fat boosts the enzyme.
