The optimal time to take iron supplements is typically on an empty stomach, about 1-2 hours before or after meals. According to research, taking iron supplements with vitamin C can enhance absorption by up to 67%.

However, if you experience stomach discomfort, you can take it with food, but avoid these items:

  • Calcium-rich foods (dairy products)
  • Coffee and tea
  • Whole grains
  • Eggs

For best absorption, pair your supplement with vitamin C-rich foods like oranges or strawberries.
