Can I get enough iron on a vegan diet?
Summary
Yes. Plant sources of iron include legumes, tofu, tempeh, fortified cereals, and leafy greens. Pairing iron-rich foods with vitamin C significantly enhances absorption.

Key Points
- 1Yes, with attention to iron-rich foods and absorption enhancers.
- 2Plant foods contain non-heme iron, which is absorbed differently than heme iron from meat.
- 3While absorption rates are lower, this can be significantly improved with simple strategies.
Evidence Summary
Best vegan iron sources:
Legumes:
-
Lentils: 6.6mg per cup (cooked)
-
Chickpeas: 4.7mg per cup
-
Kidney beans: 3.9mg per cup

Soybeans: 8.8mg per cup
Soy products:
-
Tofu (firm): 3.4mg per half cup
-
Tempeh: 4.5mg per cup
-
Edamame: 3.5mg per cup
Fortified foods:
-
Many cereals: 4-18mg per serving
-
Some plant milks: 2-4mg per cup
Other sources:
-
Pumpkin seeds: 2.5mg per oz
-
Quinoa: 2.8mg per cup
-
Spinach: 6.4mg per cup (cooked)
-
Dark chocolate: 3.4mg per oz
Iron needs:
Vegans may need 1.8x the RDA due to lower absorption:
-
Men: 14mg/day (vs 8mg for omnivores)
-
Premenopausal women: 32mg/day (vs 18mg)
-
Postmenopausal women: 14mg/day
Evidence quality: High—based on clinical nutrition research and dietetic association guidelines.

Practical Takeaways
Enhancing absorption:
Do this: Eat iron-rich foods with vitamin C
-
Squeeze lemon on lentils
-
Add bell peppers to bean dishes
-
Drink orange juice with fortified cereal
-
Include tomatoes in meals
Avoid these with iron-rich meals:
-
Coffee and tea (tannins inhibit absorption)
-
Calcium supplements (take at different times)
-
High-fiber foods in excess
Testing: Get ferritin levels tested periodically, not just hemoglobin. Supplement only if deficient—excess iron can be harmful.
