Iron is a crucial nutrient that helps transport oxygen throughout your body, keeping you feeling lively and alert. But what if you’re not getting enough of it from your plant-based diet? Learn how vegan iron supplements can help you thrive on your vegan journey!
Iron is a mineral that can be naturally found in food. It’s an essential element in our bodies and for it to work properly and stay healthy.
So, what is vegan iron? You can find iron around in both animal and plant foods. Therefore, vegan iron is iron derived from plant-based or vegan foods.
There are two types of iron: Heme-iron found in animals and non-heme iron found in plants (vegan iron).
The difference between animal iron and vegan iron: Our bodies are better at absorbing heme-iron. Therefore, many people think that iron from plant foods isn’t as good. However, plant-based iron is just a little less efficient at getting absorbed. This means for the same amount of animal iron and vegan iron that is eaten, more iron will be absorbed into the body with animal iron than vegan iron. However, they both are the same once absorbed. Hence, vegans only need to consume more iron to meet needs when on a plant-based diet.
The benefit of vegan iron: Getting iron from vegan sources can actually be good for us! Moreover, when we eat plant-based iron, our bodies learn to control how much gets absorbed. This means we only absorb the right amount of iron that our bodies need to stay healthy. Thus, vegan iron sources help us keep things in balance and the risk of iron overload is minimized.
The Dietary Reference Intakes (DRI) for iron, including Recommended Dietary Allowances (RDA), Adequate Intakes (AI) and the Upper Level (UL), are usually set for people who eat meat, not vegetarians or vegans. However, the Institute of Medicine (IOM) suggests that vegetarians, including vegans, should aim for 1.8 times more iron than what’s recommended (RDA or AI) for meat-eaters.
This extra iron helps make up for the fact that the kind of iron in plant foods (non-heme iron) isn’t as easily absorbed by our bodies as the kind found in meat (heme iron). So, it’s like a little extra insurance to make sure we get enough iron even if less iron is absorbed from plant-based foods.
| Age | RDA or AI for omnivores | Upper Level (UL) | IOM recommendation for vegetarians & vegans | |
| Males | Females | ( RDA x 1.8) | ||
| Birth to 6 months* | 0. 27 mg/day | 40 mg/day | n/a | |
| 7 – 12 months | 11 mg/day | 40 mg/day | 19.8 mg/day | |
| 1 – 3 years | 7 mg/day | 40 mg/day | 12.6 mg/day | |
| 4 – 8 years | 10 mg/day | 40 mg/day | 18 mg/day | |
| 9 – 13 years | 8 mg/day | 40 mg/day | 14.4 mg/day | |
| 14 – 18 years | 11 mg/day | 45 mg/day | 19.8 mg/day | |
| 19 – 50 years | 8 mg/day | 18 mg/day | 45 mg/day | 32.4 mg/day |
| 14 – 50 years & pregnant | n/a | 27 mg/day | 45 mg/day | 48.6 mg/day** |
| 14 – 50 years & lactating | n/a | 9 – 10 mg/day | 45 mg/day | 16.2 – 18 mg/day |
| 51+ years | 8 mg/day | 8 mg/day | 45 mg/day | 14.4 mg/day |
*For infants at birth to 6 months old, foods have not yet been introduced. Moreover, whether the baby is being breastfed or receiving infant formula, they are likely to receive enough iron to meet their needs.
**Read the section “How much iron is too much?” to understand why the recommended iron intake for pregnant women aged 14 to 50 years old is higher than the upper level.
It’s important to be careful when it comes to iron intake because excessive iron levels in the body can also lead to health problems. Therefore, the Upper Level (UL) for iron intake is set to provide guidance and prevent the harmful effects of iron overload.
For people aged 13 and younger: The UL for iron is set at 40 mg per day.
For people aged 14 and older: The UL for iron is set at 45 mg per day.
However, this UL doesn’t apply to individuals who are only consuming plant-based sources of iron and only intaking non-heme iron.
Why? Because Dietary Reference Intakes (DRI), such as the RDA and UL, are set for people who eat meat and therefore, have a higher intake of heme-iron, which is more readily absorbed than non-heme iron.
Disclaimer: If you are vegan and are taking vegan iron supplements, the UL applies to you, as iron in supplements are typically readily absorbed.

Iron is an essential nutrient for the body, and while animal products are a common source of iron, there are plenty of vegan-friendly options available. Therefore, vegans can maintain healthy iron levels by being mindful of their dietary choices and incorporating iron-rich plant-based foods into their meals. Basically, the key is maintaining a balanced vegan diet.
Here are some strategies for vegans to keep their iron levels up:
If you have concerns about your iron levels or dietary choices, consider consulting with a plant-based registered dietitian who can provide personalized guidance and recommendations.
Many vegan foods that are iron-fortified are often also B12-fortified. Therefore, choosing vegan fortified foods is a good way to ensure adequate intake of both iron and B12. However, it is important to check nutrition labels to ensure iron and B12 content.
Moreover, it is important to ensure you regularly consume B12-fortified foods, as there are limited vegan sources of B12. If not, taking a vitamin B12 supplement is a reliable and highly recommended way to meet your needs.

Anemia is a health condition characterized by a shortage of healthy red blood cells (RBCs) or a decrease in the amount of hemoglobin, a protein in RBCs responsible for carrying oxygen around your body. Hence, anemia results in reduced oxygen delivery to the body’s organs. Therefore, your body won’t be getting the oxygen it needs to function properly, which can lead to several health problems.
How can your diet cause anemia? Nutritional deficiency anemia is a form of anemia caused by diet deficiency. Moreover, diet can contribute to anemia in several ways:
Iron deficiency anemia, or IDA, is a type of anemia that happens when your body doesn’t have sufficient iron. This can occur if you’re not eating enough iron-rich vegan foods. So, if you’re not getting enough iron from your vegan diet, it can lead to IDA.
Note: Iron deficiency can be present without anemia.
Did you know…
You can regularly monitor your iron levels by taking blood tests. This is highly recommended when on a vegan diet to ensure health. However, other than blood tests, you may start getting signs or symptoms of iron deficiency, such as:
For anemia caused by iron deficiency, symptoms may include:

Vegans can develop anemia if they don’t pay attention to their dietary choices and nutritional intake. Anemia is a condition characterized by a deficiency in red blood cells or a decrease in the body’s ability to carry oxygen to its tissues. There are several types of anemia, but the most common one is iron-deficiency anemia.
Here are some reasons why vegans might be at a higher risk of developing anemia, particularly iron-deficiency anemia:
Vegans can maintain healthy iron levels and avoid IDA with proper planning and a well-balanced diet. Consulting with a vegan registered dietitian or healthcare professional can provide personalized guidance based on individual dietary preferences and needs.
Whether or not people with anemia should go vegan depends on a few things:
1. The kind of anemia they have.
2. How bad their anemia is.
3. If they can plan and stick to a balanced vegan diet.
For diet-related anemias: If you’re thinking about going vegan and you have anemia, it’s important to make sure you get all the right nutrients, like iron, vitamin B12, and folate. Not eating enough of these nutrients could worsen your anemia. Hence, to make this work, you need to be really careful about what you eat.
With severe anemia: In some cases, you may need to take supplements to help with your anemia. This is especially true if your anemia is caused by your diet or if you can’t get enough of the right nutrients from food alone. So, before you make any big changes to your diet, talk to a doctor or a plant-based registered dietitian to figure out the best plan for you.
Maintaining a balanced vegan diet: A key aspect in ensuring adequate nutrient intake on a vegan diet is diversity. It is important to eat a variety of whole foods and fortified foods to ensure needs are met. Moreover, maintaining a balanced and well-diversed diet can stop your nutrient levels, that may be causing anemia, from dropping. Hence, this requires careful planning and attention to nutrient intake.
If you have low iron levels or have difficulty meeting your iron needs through diet alone, it may be best for you to take iron supplements. These should be taken under medical supervision to avoid iron overload.
Therefore, if you have concerns about your iron levels or are at risk of iron deficiency anemia, consider getting regular blood tests to monitor your iron status.
Increasing iron levels takes time, and it’s best to do it gradually to avoid iron overload. That being said, the quickest way to increase iron levels is through iron supplements. However, iron supplementation should be managed under the guidance of a healthcare provider or registered dietitian to prevent iron toxicity.
Moreover, if you have severe iron deficiency or underlying health issues, your healthcare provider may recommend more aggressive treatments like iron infusions.
Iron toxicity occurs when there’s too much iron in your body, such that damaging substances called free radicals are created. These free radicals harm your organs like the liver or blood vessels.
Signs and symptoms of iron toxicity include:
Note: Symptoms may temporarily disappear for a few hours and then reappear after a day or more.
Disclaimer: Not all individuals with iron toxicity will experience all these signs or symptoms, and the severity of these symptoms can vary among individuals. Additionally, some of these signs may resemble those of other medical conditions, making it important to seek proper guidance if you suspect iron toxicity.
Yes, vegans can take iron supplements.
Eating iron rich foods is a key part of treating anemia caused by low iron levels. However, you may also need to take iron supplements to avoid iron-deficiency, iron-deficiency anemia or rebuild iron stores in your body. Hence, iron supplements are a common way to address iron deficiency anemia or to increase iron levels when dietary sources are insufficient.
Possible side effects of iron supplements include:
These side effects can vary in severity from person to person. Moreover, these symptoms usually get better as your body gets used to the iron supplements. However, if the side effects persist and bother you a registered dietitian can provide guidance on managing side effects and adjusting your iron supplementation if needed.
Iron supplements may be taken as capsules, tablets, and liquids.
| Physical form | Advantages | Disadvantages |
| Capsules & Tablets | Convenience: Iron pills are typically more convenient and have a longer shelf life compared to liquid supplements. They are easy to carry and can be taken without the need for refrigeration. Accurate Dosage: Iron pills provide a precise dosage per tablet or capsule, making it easier to track and follow your dose recommendations. Stability: Iron pills are less prone to oxidation and spoilage, which can affect the potency of liquid iron supplements over time. Variety: There is a wide variety of iron pills available, including different forms (ferrous sulfate, ferrous gluconate, ferrous fumarate) and formulations (slow-release, extended-release, etc.), allowing for options tailored to individual needs. | Digestive tolerance: GI side-effects are common. However, GI symptoms and tolerance to them may vary between individuals. Moreover, some may not experience any at all. |
| Liquids | Absorption: Liquid iron supplements are often marketed to have higher absorption rates compared to iron pills. This can be attributed to the fact that the iron in liquid form is already in a dissolved state (ferrous form), making it easier for the body to absorb. Digestive Tolerance: Some people find liquid iron supplements to be gentler on the stomach and less likely to cause common side effects like constipation or stomach upset that are associated with iron pills. Adjustable Dosage: Liquid iron supplements allow for more flexibility in adjusting the dosage. You can easily measure and customize the amount you take, which can be useful for individuals with specific iron requirements. | Convenience: Iron liquids are usually less easy to carry around. Accurate Dosage: It is harder to provide a precise dosage with iron liquids. Stability: Iron liquids may be more prone to oxidation and spoilage. Variety: There are less options, in terms of iron formulations, with iron liquids. |
Ultimately, the choice between liquid iron and iron pills depends on your specific circumstances and preferences. Both forms of iron supplementation have their advantages and disadvantages.
Here are some factors to consider when deciding:
There is a variety of oral iron supplements available, each with different formulations. These formulations differ in the amount of elemental iron they contain and their absorption rates.
What is elemental iron? Elemental iron is the actual amount of pure iron that is available for absorption by the body. When you take an iron supplement, the total weight or dose of the supplement includes both the iron itself and other compounds (i.e. salts) that are used to deliver the iron in a form that can be easily consumed. Hence, elemental iron represents the portion or weight of the supplement that your body can use for its iron needs.
How to determine the amount of elemental iron in a supplement? Different iron supplements may contain varying amounts of elemental iron, depending on the specific iron compound used in the formulation. Hence, for each iron supplement product, it is important to check the labels to determine the dose of elemental iron. It will vary from product to product.
What is the best iron formulation? No specific iron formulation is recommended over others. Although polysaccharide, polypeptide and other forms can be taken with food to lessen stomach side effects, they may costlier than iron salt forms. Moreover, ferrous salts are the most readily absorbed supplements. Therefore, in the case of low iron levels, it may take longer to restore iron level with ferric salts or other supplements that are not ferrous salts. Hence, it really comes down to patient tolerance of GI side effects.
Types of iron supplement formulations:
| Type of Iron Formulations | What you should know | To improve absorption |
| Ferrous salts | ||
| Ferrous sulfonate | Affordable and easily absorbed, but may cause stomach problems. Different types of this supplement have similar absorption rates and side effect chances. | Requires stomach acid for absorption. Therefore, it is best to consume on an empty stomach as there will be more acid available to help with absorption. It is recommended that the stomach be empty at least 1 hour before or two hours after a meal. |
| Ferrous gluconate | ||
| Ferrous fumarate | ||
| Ferric salts | ||
| Ferric Pyrophosphate | Less readily absorbed compared to ferrous salts. | Same as with ferrous salts. |
| Other forms | ||
| Polysaccharide Iron Complex | These forms are advertised as having less GI-related side effects than ferrous and ferric salts. Therefore, they are often used when side-effects from ferrous salts or ferric salts are not well tolerated. | Can be taken with or with food. Stomach acid is not needed for absorption. |
| Carbonyl Iron | Requires stomach acid for absorption. Therefore, it is best to consume on an empty stomach as there will be more acid available to help with absorption. It is recommended that the stomach be empty at least 1 hour before or two hours after a meal. | |
| Chelated Iron (Bisglycinate) | ||
| Heme Iron | Can be taken with or with food. Stomach acid is not needed for absorption. | |
The choice of the most gentle iron supplement for the stomach can vary from person to person, as individual tolerance to iron supplements can differ. However, certain types of iron supplements and formulations are generally considered to be gentler on the stomach. This includes:
In addition, slow-release or extended-release formulation and low dosages may reduce the risk of stomach upset and/or GI side effects.
Consulting with your doctor or a registered dietitian can help you make an informed choice and ensure that your iron supplementation is both effective and well-tolerated.
Yes, of course! Plant-based iron supplements may be synthetically formulated or made with iron from plant sources. Hence, there are many suitable for those who prefer to avoid animal-derived ingredients.
How to choose vegan iron supplements?

The best way to take iron supplements truly depends on what type of vegan iron supplement you choose to take.
Ferrous salts for example: Ferrous salts (ferrous sulfate, ferrous fumarate, and ferrous glycinate) require stomach acid to be absorbed. Therefore, they are best consumed on an empty stomach and with doses of vitamin C. Moreover, medications that will reduce stomach acid are to be avoided or taken at another time than these iron supplements.
To determine the best way to take your vegan iron supplement of choice, read your product’s label, consult with your doctor or your plant-based registered dietitian.
The timing of iron supplementation, whether in the morning or at night, can vary depending on individual preferences and any specific guidance provided by a healthcare professional. There is no universally “better” time to take iron supplements.
However, it is important to take your vegan iron supplements at the same time every day. Consistency helps ensure that you receive a steady supply of iron. Hence, the decision to take your vegan iron in the morning at night should be one that will help you to stay consistent. Therefore, your decision should align with your daily routine and personal preferences.
Here’s what to avoid of when you’re taking iron supplements to ensure good iron absorption:
