Best Iron-Rich Foods for Horses

Ranked by iron content among foods safe for horses in the Creature Feast catalog.

Spinach per 100g: approximately 2.7mg iron Spinach is very high in iron (about 2.7mg per 100g) but should be offered only as an occasional treat. Horses rarely need additional iron — most forages already provide 5-10 times the requirement.

Dandelion greens per 100g: approximately 3.1mg iron Dandelion greens are a good iron source (about 3.1mg per 100g) that horses naturally encounter during grazing. They also provide vitamins that support iron utilization.

Oats per 100g: approximately 4.7mg iron Oats provide moderate iron at about 4.7mg per 100g. Combined with iron from hay, the daily grain ration contributes to the already-generous iron supply.

Alfalfa Hay per kg: approximately 100-300mg iron Alfalfa hay provides about 100-300mg iron per kg. As with most forages, it supplies more iron than horses require, which is why supplementation is almost never needed.

Timothy Hay per kg: approximately 100-500mg iron Timothy hay typically contains 100-500mg iron per kg, often providing several times the daily requirement from forage alone.

Pumpkin seeds per 100g: approximately 8.8mg iron Pumpkin seeds provide about 8.8mg iron per 100g, making them one of the more iron-dense treats. However, given that most horses already have excess dietary iron, this is a consideration rather than a benefit.
