Anemia and Brain Fog: 5 Clarity-Boosting Strategies
Discover the link between anemia and brain fog plus our expert recommended clarity boosting strategies.
Updated December 6, 2023.
Brain fog is a colloquial term for a set of cognitive symptoms, including lack of mental clarity, forgetfulness, and difficulty concentrating. Although many factors like lack of sleep and stress can contribute, you may be experiencing brain fog because of low iron.
Low red blood cell count or inadequate hemoglobin levels characterize anemia. Menstruating women and athletes are two groups particularly at risk for the most common form of anemia, iron-deficiency anemia. Anemia can also occur in cancer, kidney, and autoimmune disease patients. [1, 2]
Whether you or a loved one are struggling with anemia-related confusion, these expert-backed strategies can help you regain mental clarity and improve your well-being.

Iron-deficiency anemia
Iron deficiency anemia affects 30% of the global population. [3] Low iron levels can result in reduced oxygen supply to the brain, which can lead to memory problems and concentration issues.
Connection between anemia and cognitive clarity
Understanding the link between iron deficiency and brain fog may help support actions that enhance cognitive function and overall well-being. By recognizing this connection, you can take proactive measures to address these issues through a combination of nutrition, physical activity, and lifestyle modifications.
Does anemia cause brain fog?
Anemia can lead to reduced hemoglobin, the protein in red blood cells that carries oxygen. While it may not directly cause brain fog, it can make concentrating difficult for you due to inadequate oxygen supply to the brain.
5 Strategies for boosting clarity
1. Iron-rich foods
Incorporating iron-rich foods into your daily diet can improve cognitive clarity and overall mental well-being. [4]
Some iron-rich foods you can include in your diet are:
- Poultry
- Beef
- Fish
- Nuts and seeds
- Leafy greens
A protein-packed meal not only provides the essential iron needed for the production of red blood cells but also offers other vital nutrients like B vitamins and zinc, which further support cognitive function and overall health.
2. Iron supplements and patches
Prescribed iron supplements and patches can help alleviate brain fog and cognitive symptoms associated with iron deficiency. While both effectively boost iron levels, they differ slightly.
Before considering iron supplementation, visit a qualified healthcare professional. They can assess your health status, medical history, and dietary needs to determine if you need the extra mineral.
You usually take supplements orally as pills or liquid, which release iron into the bloodstream for absorption through the digestive system. On the other hand, iron patches adhere to the skin, gradually releasing the mineral into your bloodstream over time.
Do iron patches work for anemia?
Iron patches work for anemia, but the rate of iron absorption through the skin isn't as reliable as oral supplements or dietary sources. This is because the skin is a natural barrier that limits its absorption.
3. Vitamin C-rich foods
Vitamin C enhances the absorption of dietary iron, especially non-heme sources found in plant-based foods and iron supplements. Then, it converts iron into a more soluble form, making it easier for the body to absorb. [5]
To combat lightheadedness caused by anemia, pair iron-rich foods with vitamin C sources like citrus fruits to enhance absorption.
4. Regular exercise
While heavy exercise is not recommended for those with iron-deficiency anemia, performing light to moderate exercise regularly can help mitigate the effects of anemia-related brain fog. Engaging in physical activity enhances your cardiovascular fitness and improves blood circulation throughout the body. [6]
Improved circulation helps deliver oxygen and essential nutrients more efficiently to the brain, which can alleviate some of the cognitive challenges associated with anemia.
5. Managing mental health
Iron is an essential nutrient that plays a crucial role in various bodily functions, including the production of neurotransmitters like serotonin and dopamine, which are closely linked to mood regulation.
Can low iron cause mental health issues?
There's a link between iron deficiency and increased anxiety levels. [7] Iron is involved in the regulation of neurotransmitters that influence anxiety, so an imbalance may lead to heightened anxiety symptoms.
Navigating the fog: reclaim your mental clarity
Addressing anemia and maintaining optimal red blood cell health requires a multifaceted approach that combines medical guidance with dietary choices and lifestyle considerations. If your healthcare provider recommends it, an iron supplement can also be a valuable step in replenishing iron stores and alleviating anemia-related symptoms.
InsideTracker offers comprehensive biomarker analyses, including a variety of iron-related markers, a tailored Action Plan, and a wealth of resources for improving overall well-being. However, it's not meant to diagnose or treat medical conditions. If you have any medical concerns, please consult a qualified healthcare professional.
