Vegans can meet their iron requirements through lentils, beans, oats, tofu, whole grains, and green leafy vegetables. The absorption of plant-based iron can be significantly improved by vitamin C.
Many people believe that vegans have an iron deficiency. At the same time, some influencers or fitness coaches are suddenly recommending liver or red meat again - supposedly for "better iron." But what's the truth behind this? We'll examine this logically and scientifically now.
What are the best vegan iron sources?
As you can read in our Nutrient and Supplement Guide, vegan iron sources are primarily:
- Whole grain products
- Oatmeal
- Soy granules
- Tofu
- Tempeh
- Lentils
- Chickpeas
- Beans
- Green leafy vegetables
- Nuts and seeds
These iron-rich foods are usually sufficient to meet iron requirements. Additionally, supplements can be used - but these are not generally necessary and should only be taken if a deficiency has been proven. This applies not only to plant-based diets; omnivores can also experience iron deficiency.
→ More on this in our FAQ on supplements for vegan diets.
What is the difference between heme iron and non-heme iron?
Iron is not just iron - biochemically, two forms of iron are fundamentally distinguished: heme iron and non-heme iron.
Heme iron:
- Comes from meat and liver
- Is bound to a heme molecule
- Is absorbed more easily
Non-heme iron:
- Comes from legumes, grains, and vegetables
- Also found in iron supplements
- Exists as free iron
The body treats these forms differently. However, a very important point is often omitted by online coaches: while heme iron is absorbed more efficiently, more absorption does not automatically mean healthier.
Is plant-based iron inferior to iron from meat?
With heme iron, the regulation of iron absorption is less strong than with non-heme iron. In fact, heme iron is discussed as a possible mechanism that could contribute to the development of colorectal cancer through high meat consumption. The consumption of red and processed meat has been associated with an increased risk of colorectal cancer for years. Therefore, presenting animal iron per se as superior is scientifically too simplistic.

Can vegans get enough iron?
In short: Yes. Major dietary societies generally consider a well-planned vegan diet to be possible - also concerning iron. Vegan iron supply works without problems in practice for many people.
Key factors are:
- Sufficient calorie intake
- Regular iron-rich foods (list above)
- Blood value checks and, if necessary, sensible use of supplements
A helpful trick: The combination with vitamin C greatly helps to make plant-based iron more available.
For example:
- Lentils + bell peppers
- Oatmeal + berries
- Beans + lemon juice
→ This can improve iron absorption.
Are meat and liver really better iron sources?
As we have established, iron requirements can be met through a vegan diet. Heme iron has higher bioavailability, but non-heme iron is more strictly regulated. Which form is healthier in the long term depends on the focus. Since iron requirements can also be met purely plant-based, the recommendation of meat or liver as a necessary iron source cannot be scientifically justified.
The ethical perspective: Given that animals' lives are taken for meat and liver, it is neither neutral nor responsible to recommend meat and liver as "better" iron sources.
Conclusion - Meeting iron needs on a vegan diet is possible
While heme iron from meat is absorbed more easily than non-heme iron from plants and supplements, this very fact could also promote problematic long-term effects. Therefore, the statement that vegans cannot meet their iron requirements is not scientifically tenable. Rather, it is about a sensibly planned plant-based diet.
This is easier than ever today with the high availability of whole grain and soy products, lentils, beans, and green leafy vegetables. Additionally, combining with vitamin C can improve iron absorption.
