The Claim
Supplementing laying hen diets with paprika extract (30 mg/kg), marigold petal extract (60 mg/kg), or Paracoccus cell powder (28 mg/kg) causes a significant increase in singlet oxygen quenching activity of egg yolk compared to unsupplemented control diets, with this effect observed in both Rhode Island Red and Silky Fowl breeds after 4 weeks of supplementation.
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.
Giving hens certain natural supplements like paprika or marigold extract makes their egg yolks better at neutralizing harmful oxygen, and this works in two different types of chickens after a month.

What the research says
1 studyStudy: Effect of Dietary Carotenoid on Egg Yolk Color and Singlet Oxygen Quenching Activity of Laying Hens
The study gave hens the same supplements mentioned in the claim and found that the egg yolks became better at neutralizing harmful molecules, just like the claim says.
