Timing

Many foods affect iron absorption significantly. Coffee — if it's high in tannins (tea, coffee, chocolate), phytates (whole grains, legumes), or calcium (dairy), space it 2+ hours from your iron supplement. Citrus fruits and bell peppers (vitamin C-rich) enhance iron uptake — pair them together.
