Improves cognitive function
Iron is found in every cell and plays a vital role in many physiological processes, including the transportation of oxygen and the synthesis of enzymes. It is also necessary for cognitive function, as it is involved in the production of neurotransmitters and the metabolism of energy in the brain. (2)
Studies have shown that iron deficiency can lead to cognitive impairment, particularly in children and pregnant women. However, iron supplementation can improve cognitive function in both iron-deficient and non-deficient individuals.
Iron is a essential nutrient for optimal brain function. If you are not getting enough through your diet, consider supplements to help improve your cognitive function.
Fosters better sleep
Iron is what you’re the body needs to make hemoglobin, which carries oxygen in the blood. When people don’t have enough iron, they can develop iron deficiency anemia. This condition can cause fatigue, pale skin, and sleep disturbances, among other symptoms.
Some research suggests that iron may also play a role in sleep. For example, one study found that iron deficiency anemia was linked with insomnia. Another study found that taking iron supplements improved sleep quality in women with restless legs syndrome.
