Calcium and Iron Absorption Inhibition

Dr. Ronald Roth's Answer

  • Yes, calcium intake can inhibit the absorption of both heme and non-heme iron, although the inhibitory effect on non-heme iron is generally more pronounced.
  • Calcium interferes with the cellular uptake mechanisms of iron in the gastrointestinal tract, acting as a direct competitive inhibitor regardless of the iron source.
  • While heme iron is typically less affected by dietary factors compared to non-heme iron, high doses of calcium (especially from supplements or dairy products) have been shown in studies to negatively impact the absorption of both forms.
  • To optimize mineral balance, it is often recommended to consume calcium and iron supplements or iron-rich meals at different times of the day to minimize this interaction.
