Iron is an essential mineral that plays a vital role in various processes within the body, including neurotransmitter synthesis. Neurotransmitters are chemical messengers in the brain that facilitate communication between nerve cells. Dopamine, norepinephrine, and serotonin are three important neurotransmitters involved in brain function.

Role of Iron in Neurotransmitter Synthesis

Dopamine is associated with motivation, reward, and pleasure. Norepinephrine is involved in attention, focus, and alertness. Serotonin is linked to mood regulation, sleep, and appetite control. These neurotransmitters are crucial for maintaining optimal brain function and overall well-being.

Iron is necessary for the synthesis and metabolism of these neurotransmitters. It acts as a cofactor for enzymes such as tyrosine hydroxylase, which converts tyrosine to dopamine and further to norepinephrine. Without sufficient iron, the production and regulation of these neurotransmitters may be impaired.

Iron Deficiency and ADHD

ADHD (Attention-Deficit/Hyperactivity Disorder) is a neurodevelopmental disorder characterised by persistent patterns of inattention, hyperactivity, and impulsivity that can significantly impact daily functioning and quality of life. Research suggests that neurotransmitter imbalances, particularly dopamine and norepinephrine, play a role in its development and symptoms.

In a 2017 study, researchers found a potential association between iron deficiency and adult ADHD, specifically among women. The study aimed to explore the relationship between iron deficiency and the prevalence of ADHD symptoms in adult women. The findings indicated a higher prevalence of ADHD symptoms among women with iron deficiency compared to those in the control group.

A recent 2021 study investigated the effects of iron supplementation on behavioural and attention capabilities in children. The study aimed to explore whether daily iron supplementation could positively impact these aspects. This study provides promising evidence regarding the potential benefits of iron supplementation in improving behavioural and attention capabilities in children.

Causes of Low Iron Levels

Low iron levels can result from various factors, including inadequate dietary intake of iron-rich foods, poor iron absorption due to digestive issues, chronic inflammation, heavy menstrual bleeding, or a genetic predisposition.

Dietary Recommendations to Increase Iron Intake

To increase iron intake, emphasise consuming iron-rich foods such as leafy green vegetables, legumes, nuts, seeds, and lean meats. Pair these foods with vitamin C-rich foods to enhance iron absorption. For example, enjoy a spinach salad with citrus dressing or pair bell peppers with hummus.

Iron is crucial in neurotransmitter synthesis, affecting brain function and overall well-being. Ensuring adequate iron levels through diet or supplementation can have significant benefits, particularly for individuals with ADHD. Understanding the importance of iron and its impact on neurotransmitters can help guide dietary choices and improve mental health.
