Iron Comparison

Why Wild Spinach Has More Iron

Wild growth — Plants growing without fertilizer must absorb minerals more efficiently from the soil
Stress response — Environmental stress triggers production of protective compounds, including minerals
No dilution — Cultivated spinach is bred for high yield, which can dilute mineral content

How to Maximize Iron Absorption

Combine with vitamin C — Lemon juice, tomatoes, or peppers increase iron absorption by 3-6x
Avoid tea/coffee with meals — Tannins reduce iron absorption
Cook lightly — Reduces oxalates (which bind iron) while preserving nutrients
