Why this page doesn't claim "Egg works"

Whole foods almost never have RCTs — the evidence sits on the ingredients. So this page does one honest thing: it lists which graded ingredients Egg contains, how much, and how far that is from the studied dose. It makes no efficacy claim about Egg itself.

Bottom line: The egg's standout is choline (the best budget source) along with vitamin B12 and selenium; lutein and vitamin D are on the low side and just a bonus.
