Signature ingredient: Iron — S-grade evidence (Iron Deficiency Anemia, ~83% of the studied dose per serving)
Standard nutrients per USDA FoodData Central · phytochemicals (lutein / K2 / sulforaphane etc.) are literature estimates, varying by variety and processing

Why this page doesn't claim "Pork liver 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 Pork liver contains, how much, and how far that is from the studied dose. It makes no efficacy claim about Pork liver itself.
Bottom line: Pork liver is a nutrient bomb: heme iron, vitamin B12, copper, and folate are all very high and well absorbed. But its vitamin A is the animal-derived preformed type, exceeding the daily value 7-fold - excess carries liver toxicity and teratogenic risk, so pregnant women especially should limit it; more is not better.
