Recent research has shed light on the significant impact of iron levels on mental health. Iron is a crucial element for the production of neurotransmitters that directly influence mental well-being. Inadequate iron levels can exacerbate symptoms of depression, anxiety, and schizophrenia. Interestingly, even individuals without iron-deficiency anemia can benefit from iron supplementation, as it can enhance mood and reduce fatigue. Unfortunately, there is limited awareness among healthcare providers and patients regarding the vital link between iron and mental health.
As evidence continues to accumulate, individuals experiencing symptoms of depression, anxiety, or other mental health conditions may consider getting tested for iron levels and incorporating iron-rich foods or supplements into their diets. While many acknowledge that mental health issues are rooted in various factors such as brain structure, genetics, and life experiences, the role of nutrition and nutrient utilization should not be overlooked. Increasing research suggests that iron, in particular, plays a pivotal role in mental health, and insufficient levels can impact symptoms.
Dr. Stephanie Weinberg Levin, a psychiatrist at Michigan Medicine and the VA Ann Arbor Healthcare System, delved deep into this subject during her fellowship in integrative psychiatry. Together with Dr. Theresa Gattari, a former psychiatry resident, they summarized the current state of knowledge on this topic in a review article for fellow psychiatrists.
Iron-rich foods include dried beans, dried fruits, eggs (especially egg yolks), iron-fortified cereals, liver, lean red meat (especially beef), poultry, dark red meat, oysters, tuna, salmon, and whole grains. It is crucial for everyone to prioritize consuming iron-rich foods, as many individuals do not obtain sufficient iron through their diets. However, individuals with mental health conditions should specifically discuss with their healthcare providers the possibility of ordering a blood test that measures iron levels in a specific manner.
Dr. Levin emphasizes the significance of iron deficiency, stating, “Iron is the most common nutrient deficiency and can have a big impact.” It is possible to have iron deficiency without anemia, yet many mental health providers are unaware that low iron levels alone are linked to worsened symptoms and that supplementation has been associated with symptom improvement. Therefore, it is important for primary care providers to consider testing iron levels, not just in cases of anemia or specific health conditions known to affect iron levels.
Nutrient deficiencies can significantly impact overall well-being, which is why Dr. Levin advises individuals diagnosed with mental health conditions to discuss testing and potential supplementation with their healthcare teams. Iron plays a vital role in the production of key brain chemicals, including serotonin, dopamine, and norepinephrine, all of which are essential for mental health. Research indicates a connection between low iron levels and symptoms of depression, anxiety, and schizophrenia, as observed through surveys and large-scale studies.
In addition to studying the relationship between iron levels and symptoms, researchers have investigated the effects of iron supplementation on individuals with mental health conditions. Previous studies published before 2013 showed that iron supplementation improved mental health symptoms and cognitive abilities. Numerous studies, involving individuals with and without mental health diagnoses, have demonstrated mood and fatigue improvements after iron supplementation, even among those who do not meet the criteria for iron-deficiency anemia.
Ferritin testing is particularly recommended by Dr. Levin for individuals with mental health conditions and other factors that make them susceptible to low iron levels. This includes pregnant women, young children, women with heavy menstrual bleeding, frequent blood donors, cancer patients, individuals who have undergone gastrointestinal surgeries or have digestive disorders, and those with heart failure.
For individuals with mental health symptoms and low ferritin levels, there is currently no consensus on the ideal level to target through dietary changes and supplementation, nor on the frequency of testing after making these changes.

What is the relationship between iron deficiency and mental health?
Iron deficiency can have a significant impact on mental health. Research shows that inadequate iron levels can worsen symptoms of depression, anxiety, and schizophrenia. Iron is essential for the production of neurotransmitters that directly influence mental well-being. Supplementing with iron or consuming iron-rich foods can help improve mood and reduce fatigue, even in individuals without iron-deficiency anemia.
How can iron supplementation benefit mental health?
Iron supplementation can be beneficial for mental health. Studies have shown that iron supplementation can lead to improvements in mental health symptoms, including mood and fatigue. Even individuals who do not meet the criteria for iron-deficiency anemia can experience positive effects on their mental well-being through iron supplementation. However, it is important to consult with a healthcare provider before starting any supplementation regimen.
Which foods are rich in iron?
There are several iron-rich foods that can help maintain adequate iron levels. Some examples include dried beans, dried fruits, eggs (especially egg yolks), iron-fortified cereals, liver, lean red meat (especially beef), poultry, dark red meat, oysters, tuna, salmon, and whole grains. Incorporating these foods into your diet can contribute to maintaining optimal iron levels and supporting mental health.
Should everyone get tested for iron levels?
While iron levels play a role in mental health, not everyone needs to get tested for iron levels. It is particularly recommended for individuals with mental health conditions and those who have factors that make them susceptible to low iron levels, such as pregnant women, young children, women with heavy menstrual bleeding, frequent blood donors, cancer patients, individuals with gastrointestinal surgeries or digestive disorders, and those with heart failure. Consulting with a healthcare provider can help determine if testing for iron levels is necessary.
How often should iron levels be tested after making dietary changes or supplementation?
The frequency of testing iron levels after making dietary changes or starting iron supplementation may vary depending on individual circumstances. It is advisable to consult with a healthcare provider to determine the appropriate timing for follow-up tests. Generally, testing every 4 to 6 weeks can provide insight into the impact of dietary changes or supplementation on iron levels.
Can iron supplementation be harmful?
Iron supplementation can be beneficial for individuals with iron deficiency or low iron levels. However, it is important to be cautious and follow healthcare provider recommendations. Excessive iron supplementation can lead to iron overload, which can have adverse health effects. It is essential to read labels, choose reputable brands, and inform healthcare providers about any supplements being taken to ensure safe and appropriate supplementation.
Are there other factors that affect mental health beyond iron deficiency?
Yes, mental health is influenced by various factors beyond iron deficiency. Brain structure, genetics, life experiences, stress, sleep habits, and physical activity also play significant roles. While iron deficiency can worsen mental health symptoms, it is important to consider a holistic approach that addresses multiple aspects of mental well-being. Consulting with healthcare professionals can help explore comprehensive strategies for mental health management.
