ADHD is a Nutritional, Not a Mental Problem


Attention-deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by the core symptoms hyperactivity, impulsivity and inattention. Most doctors agree that proper nutrition is essential in treating ADHD.  In fact, according to studies, with diet being a major source of essential nutrient intake, there is growing evidence linking essential nutrients to ADHD. 

"A recent meta-analysis examining dietary patterns of children and their diagnosis or symptoms of ADHD found that children who scored lower on healthy eating patterns and higher on unhealthy eating patterns had a higher risk of diagnosis or symptoms of ADHD."

Given this, there is strong evidence that along with healthy eating, certain vitamins and minerals improve ADHD symptoms.

Vitamin B1 and ADHD

Vitamin B1, also known as thiamin, is essential for brain health, playing a significant role in the nervous system's functioning, including activities in the brain, muscles, heart, stomach, and intestines. It's noteworthy that children with developmental conditions such as autism and ADHD often show deficiencies in vital nutrients, including Vitamin B1.

The Function of Vitamin B1 in the Body

Thiamin aids in the production of acetylcholine, a neurotransmitter that influences both activation and inhibition within the central nervous system. It affects pain sensation, learning, regulation of the endocrine system, and sleep patterns. Given its wide-ranging impact, the absence of adequate Vitamin B1 can lead to notable health and behavioral issues.

Early signs of thiamin deficiency include mood irritability, which can appear within days or weeks of the deficit. This symptom highlights the nutrient's role in mental and emotional health.

Nutritional Deficiencies and ADHD

Research suggests a link between ADHD and nutritional deficiencies, including a lack of Vitamin B1. For example, a study shows that children with ADHD may have lower levels of certain nutrients, suggesting a potential benefit from dietary adjustments or supplementation to improve symptoms 


"A recent systematic review and meta-analysis showed that, in fact, the type of diet ingested influences the risk of ADHD. The authors demonstrated that a healthy dietary pattern with consumption of fruits and vegetables, fish, and high in PUFAs and micronutrients such as magnesium, zinc, and phytochemicals seems to decrease the risk of ADHD by 37%." Eating Patterns and Dietary Interventions in ADHD: A Narrative Review 

Incorporating Vitamin B1 in the Diet

Ensuring children with ADHD receive sufficient vitamins, especially B1, is important for their overall brain function and can be part of a broader management strategy. 

Foods high in thiamin, such as whole grains, pork, fish, legumes, and nuts, can help maintain adequate levels of this vitamin. A diverse diet incorporating these foods may support better outcomes for children with ADHD. And while thiamin is just one aspect of nutrition, its significance for brain function makes it an area worthy of attention in the context of ADHD.

Potassium and ADHD 

Potassium is an important mineral that plays key roles in the body's overall functioning, particularly in nerve signal transmission, muscle contraction, and fluid balance. Its effects extends to cognitive functions and mental health, making it a point of interest in discussions about ADHD and nutritional influences.

This was demonstrated in a story published in Psychology Today, where they talked about the effects of "sensory overstimulation," which is common in disorders such as ADHD and autism. 

"A woman who experienced this sensory overstimulation found that it subsided about 20 minutes after taking a potassium supplement. A neurologist found that her symptoms were the same as in "hypokalemic periodic paralysis," where ion channels in the muscles become overactive when potassium levels are low. The woman found that eating a high-carb diet and eating salty foods triggered her sensory overstimulation, just like in hypokalemic periodic paralysis."

The Role of Potassium in the Body

Potassium is the third most abundant mineral in the body. It helps the body regulate fluid, send nerve signals and regulate muscle contractions. It's also crucial for maintaining electrical conductivity in the body, which affects how nerve impulses are transmitted and muscles contract. This helps regulate heartbeat, ensures proper function of muscles and nerves, and is essential for synthesizing protein and metabolizing carbohydrates.

In the brain, potassium levels influence neurotransmitter release and neuronal activity. This balance is critical for attention, learning, and behavior regulation. Disruptions in potassium levels can impact these cognitive processes, potentially exacerbating ADHD symptoms.

Potassium Deficiency and ADHD Symptoms

Emerging research suggests a possible link between potassium deficiency and exacerbated symptoms of ADHD. For instance, low levels of potassium might be associated with difficulties in concentration, increased hyperactivity, and impulsivity. While the direct relationship between potassium levels and ADHD is still being researched, these preliminary findings indicate that maintaining adequate potassium intake could be beneficial for individuals with ADHD.

Sources of Potassium

To support neurological health and potentially alleviate some ADHD symptoms, including potassium-rich foods in the diet is advisable. Foods high in potassium include bananas, oranges, potatoes, tomatoes, spinach, and beans. A diet incorporating a variety of these foods can help ensure sufficient potassium intake, supporting nerve function and overall well-being.


Magnesium and ADHD 

Magnesium plays a very important role in the body's physiological processes, particularly in brain function and the nervous system's health. It's involved in over 300 enzymatic reactions, including those critical for the production of neurotransmitters that regulate mood, cognitive functions, and behavior. This mineral is essential for energy creation, DNA synthesis, and the maintenance of nerve and muscle function, including those of the heart.

Magnesium Deficiency and Its Implications for ADHD

A significant body of research has begun to underline the correlation between magnesium deficiency and the incidence of ADHD symptoms in children. For instance, studies have shown that a substantial percentage of children diagnosed with ADHD exhibit lower levels of magnesium compared to their peers. Symptoms of magnesium deficiency can mirror those of ADHD, including decreased attention span, hyperactivity, irritability, and impulsiveness.

In one notable study published in BMC Pediatrics

[...] children receiving vitamin D plus magnesium showed a significant reduction in emotional problems (p = 0.001), conduct problems (p = 0.002), peer problems. [...] Vitamin D (50,000 IU/week) and magnesium (6 mg/kg/day) co-supplementation for a duration of 8-weeks could improve the behavioral function and mental health of children with ADHD.

Another research, published by the National Library of Medicine showed that 95% of examined children with ADHD were found to have magnesium deficiency. And yet another study showed that 58% of ADHD participants had low serum magnesium levels, suggesting a more frequent occurrence of magnesium deficiency in children with ADHD than in those without.

The Impact of Magnesium Supplementation on ADHD

The therapeutic potential of magnesium supplementation, especially in combination with vitamin B6, has been explored as a means to alleviate ADHD symptoms. Supplementation has been associated with improvements in behavioral issues, attention, and overall cognitive performance in children with ADHD. For example, a regimen of magnesium plus vitamin B6 over several months resulted in notable enhancements in attention at school, reduction in physical aggression, and a decrease in symptoms such as muscle spasms and twitching.

Dietary Sources of Magnesium

Ensuring an adequate intake of magnesium through diet is crucial. Magnesium-rich foods include leafy green vegetables (such as spinach and kale), nuts and seeds (like pumpkin seeds and almonds), legumes (beans and lentils), whole grains (such as quinoa and whole wheat bread), and fortified foods. Incorporating these foods into the diet can help address magnesium deficiency and support overall health.

Omega-3 Fatty Acids and ADHD

Omega-3 fatty acids are very important for brain health, and have been extensively studied for their potential benefits in managing ADHD. These essential fats, particularly EPA and DHA, are vital for neuronal structure and function. They play roles in cell membrane fluidity, neuroinflammation reduction, and neurotransmitter production, all of which are pertinent to ADHD symptoms.

Impact of Omega-3 on ADHD Symptoms

Studies have found that Omega-3s, which are types of fats found in fish like salmon and in supplements, can improve attention, impulsivity, and hyperactivity in some children with ADHD.

One systematic review and meta-analysis highlighted the efficacy of Omega-3 supplementation in reducing ADHD symptoms. This analysis drew from ten studies involving 699 participants and found significant benefits of Omega-3 supplementation compared to a placebo, with no evidence of heterogeneity or publication bias. The study emphasized the positive impact of higher doses of eicosapentaenoic acid (EPA) within Omega-3 supplements on ADHD symptomatology 

The findings were encouraging. This study shows that kids who took Omega-3s, especially a type called EPA, showed improvements in their ADHD symptoms more than kids who didn't take these supplements. This means they might have been less impulsive, more attentive, or calmer. 

Dietary Sources and Supplementation

Omega-3s are primarily found in fatty fish (salmon, mackerel), flaxseeds, chia seeds, and walnuts. While diet is a key source, supplementation may be beneficial for those with ADHD, under medical advice.

How Sugar Affects ADHD Symptoms

ADHD symptoms may indeed be triggered by sugar in some people.

Additional studies show that there was a connection between dietary patterns and ADHD. Results of the analysis showed that “unhealthy” dietary patterns, like a high intake of refined sugar or saturated fat, may increase the risk of ADHD.

Another recent review looked at the link between sugar and soft drink consumption and ADHD symptoms. According to the results, increased consumption of sugar and sugar-sweetened beverages caused an increase in ADHD symptoms.

Is ADHD a Nutritional and Not a Mental Problem?

The relationship between nutrition and the management of ADHD symptoms is increasingly recognized as a crucial aspect of treatment strategies. This suggests that a holistic approach to managing ADHD should explore appropriate medication and behavioral therapies as well as a carefully considered diet plan.

While this article underscores the growing awareness of the role that nutrition plays in managing and potentially improving the quality of life for those affected by ADHD, it's important for individuals with ADHD and their caregivers to always consult healthcare professionals to tailor a nutritional approach that suits their specific needs.
