Eating Vegan: Plant Sources Of Iron
Vegan iron sources are easy enough to find, but they do need a bit of help getting properly absorbed into your body.
You can find iron in most beans, as well as in leafy greens and molasses. The iron intake of most vegans and vegetarians is actually pretty high, since iron per calorie is higher in plan foods than animal foods. But there’s an issue with absorption of plant-based iron.
Iron Absorption From Plant Foods
The iron in plant foods is a different form than the iron in animal foods and can be more difficult to absorb. But there are some simple things you can do to counteract that and get plenty of plant-based iron.
Vitamin C helps your body absorb plant food sources of iron, so eating lots of vitamin C-rich foods is a great way to improve your iron levels. Leafy greens are a great source of vitamin C as well as iron, so they do double duty. Citrus, berries and bell peppers good source of vitamin C as well.
Vegans and vegetarians who eat a lot of fresh vegetables and fruit have a pretty high intake of vitamin C, and it tends to offset the lower absorption rate of plant sources of iron.
The tannins in coffee and tea (black or green) interfere with iron absorption when you drink it at the same time as you eat foods with iron. Drinking coffee and tea only between meals seems to be all right.
Phytic acid (in things like seeds, beans, grains and raw spinach and chard) also interferes with iron absorption, but vitamin C helps counteract that effect. It’s also broken down when you soak and/or cook those foods properly.
The government’s daily reference intake of iron is 8mg/day for adult men and 18mg/day for adult women before menopause. Iron needs jump to 23mg/day for pregnant women, and drop to 8mg/day for women after menopause.
Those recommendations are based on a mix of animal and plant sources of iron. For vegans, who only get plant sources, the government recommendation is to get nearly twice that amount because of the lower absorption rate.

Getting enough iron for the day entirely from food is possible, but it can be difficult for vegans to get enough – especially for women during pregnancy.
Iron supplements are one to be very careful of, because you can take too much. If you think you’re deficient, the best plan is to get your blood tested to be sure. If you are deficient, work with your doctor to figure out a safe dose for yourself to catch up.
The government’s ‘tolerable upper intake level’ (aka the maximum amount you should take without a doctor telling you to because you’re severely deficient) is 45 mg/day for adults (40mg/day for children).
