Your stomach acid is supposed to be a fiery furnace that melts iron loose from food. If you’re on antacids or have low stomach acid (common as we age), that furnace cools down. Low stomach acid = poor iron absorption—it’s that simple.
Cooking matters more than we think. Spinach you sauté with tomatoes? Iron bio-availability goes up. Raw kale in a smoothie? The oxalates in it can lock up the iron so your body barely sees it. Steaming or cooking greens is your friend.
Another quick hack: cast iron pans. No, really. Cooking acidic foods (like tomato sauce) in a cast iron skillet can leach a surprising amount of iron into your meal. It’s like eating off a supplement. Freaky but effective.

Timing Is Everything: The Dos and Don’ts
Take supplements on an empty stomach if you can handle it. If you get queasy, pair them with a small snack—but avoid dairy, eggs, coffee, and tea within an hour of that pill. I know, I know, your morning ritual is shattered.
Spread out your calcium intake. If you take a calcium supplement, save it for a different meal than your iron-rich one. Zinc and iron can also fight for absorption, so high-dose supplements are best taken at different times of day.
And if you’re really serious, wait two hours after eating iron-rich foods before drinking black tea. Yes, I said two hours. It’s annoying, but seeing the color return to your cheeks is worth the sacrifice.
