The Claim

Supplementing the diets of laying hens with 1.0% docosahexaenoic acid (DHA)–rich microalgae (Aurantiochytrium sp.) increases the DHA content in egg yolk to approximately 946 mg per 100 g of yolk, with DHA deposition reaching a plateau after approximately 30 days of feeding, indicating time-dependent saturation.

In plain English

If you feed hens a special algae supplement for about a month, their egg yolks get a big boost in a healthy fat called DHA — but after 30 days, adding more doesn’t help because the yolks can’t hold any more.

  1. Study: Time course of nutritional and functional property changes in egg yolk from laying hens fed docosahexaenoic acid-rich microalgae

    The study shows that feeding hens 1% DHA-rich algae boosts egg yolk DHA to about 946 mg per 100 g, and levels stop increasing after 30 days, just like the claim says.
