Coffee and iron can share your day—just not at the same time. Coffee’s polyphenols (and the tannin-like compounds in tea and cocoa) can temporarily block the absorption of non-heme iron, the kind found in most supplements and in plant-based foods. That’s why a perfect morning for iron isn’t a race to swallow a tablet and a double espresso together. It’s a small timing tweak: take iron with water (and, ideally, a little vitamin C), then enjoy your coffee later. You still keep the ritual; you just separate the two.
