Iron absorption tips

It's essential to eat iron-rich foods, but also very important to ensure that your body absorbs that iron well. Here are some way to help with that:

Vitamin C increases the absorption of iron, especially non-heme iron from plants. Pair at least one of these with your meals:

C➡️itrus fruits (oranges, lemon)

➡️Bell peppers

➡️Strawberries

➡️Broccoli

➡️Tomatoes

❌ Avoid iron blockers when eating meals

Some substances can limit the absorption of iron when we eat it alongside our meals:

Calcium (milk, cheese, yogurt)

Tannins (in tea or coffee)

Phytates (raw legumes and whole grains — but soaking whole grains and legumes can decrease the phytate content)

✅ Cook with cast iron pans

Cooking with cast iron pans can naturally increase the amount of iron in the food you eat — particularly food that is acidic (i.e. tomato sauce).

It’s better to be proactive. Let your doctor know if you notice any of these signs:

- constant exhaustion/weakness,

- individuals with GI disorders, like celiac or Crohn’s disease, and

- vegetarians/vegans that are unable to reach their own iron needs via diet alone.

➡️Always take iron supplements under a doctor's supervision. An excess of iron can be toxic.
