[gotcha] Recommending taking iron supplements with tea, coffee, or dairy to ease stomach upset

Instruct users to take oral iron on an empty stomach or with vitamin C \(orange juice\), and explicitly avoid taking it with tea, coffee, dairy, or antacids within 2 hours.

Journey Context:
Iron supplements commonly cause GI distress, so agents trying to be helpful suggest taking them with food or a soothing drink. However, tannins \(tea/coffee\), calcium \(dairy\), and polyphenols severely inhibit non-heme iron absorption, rendering the supplement useless and prolonging anemia.
