Top sources of iron

Updated: Mar 28, 2019

Iron, we need it for oxygen transport, making DNA and moving electrons around our body (1), but if you’re following a healthy plant-based diet what is the best source?


When eating a vegetarian diet we absorb around 5-12% of the iron we consume (2,3), for a sneaky way to increase this percentage check back in on Friday. The amount we need per day according to the NHS (3) is as follows:


8.7mg a day for men over 18 14.8mg a day for women aged 19 to 50 8.7mg a day for women over 50


Even though the bio-availability (the amount absorbed) is low, with these potent plants and bad-boy beans you’ll have no problem hitting your daily needs.
