Iron
This is what the ingredient is.
Iron is an essential mineral used in various forms for food fortification (ferrous sulfate, ferric orthophosphate, etc.). Critical for oxygen transport in blood.
Here is why it shows up on the label.
Nutrient fortification in cereals, flour, and infant formula. Essential for hemoglobin production and oxygen transport. Prevents iron deficiency anemia.
Here is what food agencies say.
FDA mandated fortification in enriched grain products. RDA: 8-18 mg/day (higher for menstruating women). Upper limit: 45 mg/day. Approved globally.
Here is what research has found.
Essential nutrient with well-documented requirement. Deficiency causes anemia - most common nutritional deficiency globally. Fortification improves public health. Heme iron (from meat) absorbed better than non-heme iron (from plants/fortification).
Here are a few things worth knowing.
Food fortification amounts are safe. Iron supplements can cause constipation, nausea, dark stools. Very high doses toxic, especially in children (accidental poisoning risk). Individuals with hemochromatosis (iron overload disorder) should limit iron intake. Fortification generally beneficial for population health.
