Magnesium absorption can be blocked by high intake of certain minerals (calcium, zinc, phosphorus, iron), phytates (in beans, grains), oxalates (spinach, chocolate), and high-fiber or processed foods, while alcohol, caffeine, and some medications (diuretics, PPIs) increase loss or interfere with uptake. To improve absorption, separate magnesium supplements from these inhibitors by a few hours, and pair them with water and easily absorbed foods.
