Frequently Asked Questions

What's the difference between heme and non-heme iron?

Heme iron (from meat, fish, poultry) is absorbed at 15-35% efficiency. Non-heme iron (from plants, supplements) is absorbed at 2-20% efficiency. Vegetarians need almost twice as much iron due to lower bioavailability.

How can I improve iron absorption?

Take iron with vitamin C (citrus, bell peppers, strawberries), avoid tea/coffee/dairy with iron-rich meals, cook in cast iron, and separate calcium supplements from iron by 2+ hours.

What are signs of iron deficiency?

Fatigue, weakness, pale skin, brittle nails, restless legs, unusual cravings for ice or starch. However, only blood tests (ferritin, hemoglobin, transferrin saturation) can confirm iron status.
