Executive function and focus are critical components of everyday productivity, yet they can be particularly challenging for neurodivergent individuals. Conditions such as ADHD, autism spectrum disorder (ASD), and anxiety-related disorders often include symptoms of impaired focus, mental fatigue, and difficulty managing cognitive tasks. While behavioral strategies and medications are common tools for managing these challenges, there is growing interest in the potential of nutritional supplements, such as magnesium glycinate, to provide additional support.
This article examines how magnesium glycinate may help improve executive function, reduce mental fatigue, and enhance focus in neurodivergent adults, drawing on scientific research and practical applications.

Understanding Executive Function in Neurodivergent Adults
Executive function refers to a set of cognitive processes that include working memory, flexible thinking, self-regulation, and the ability to plan and execute tasks. In neurodivergent individuals, these processes can be disrupted, leading to challenges such as:
- Difficulty focusing or sustaining attention.
- Problems with organizing tasks or managing time.
- Increased susceptibility to mental fatigue and overwhelm.
- Heightened sensitivity to external stimuli, affecting concentration.
Prevalence of Focus and Fatigue Issues
- ADHD: An estimated 4.4% of adults in the U.S. have ADHD, characterized by persistent inattention, hyperactivity, and impulsivity (Kessler et al., 2006).
- Autism Spectrum Disorder (ASD): Approximately 2.2% of adults have ASD, often accompanied by sensory sensitivities and difficulties with attention regulation (Maenner et al., 2020).
- Generalized Anxiety Disorder (GAD): Over 6.8 million U.S. adults experience GAD, with common symptoms including difficulty concentrating and mental fatigue (NIMH, 2021).
Given these challenges, addressing the physiological underpinnings of focus and fatigue—such as magnesium levels—may provide a valuable adjunct to conventional therapies.

The Role of Magnesium in Cognitive Health
Magnesium is a critical mineral involved in over 300 enzymatic reactions in the body, many of which directly influence brain health and cognitive function. Neurodivergent individuals are particularly susceptible to magnesium deficiencies due to factors such as dietary restrictions, heightened stress, and increased metabolic demands.
Key Functions of Magnesium for Cognitive Health
- Regulation of Neurotransmitters:
Magnesium plays a vital role in regulating excitatory and inhibitory neurotransmitters, including glutamate and GABA. Balanced neurotransmitter activity supports focus and reduces hyperactivity. - Stress Reduction:
Magnesium helps modulate the hypothalamic-pituitary-adrenal (HPA) axis, reducing cortisol levels and promoting a calmer state conducive to concentration (Tarleton & Littenberg, 2015). - Energy Production:
Magnesium is essential for ATP synthesis, the primary energy source for neurons. Adequate magnesium levels reduce mental fatigue and sustain cognitive performance. - Neuroprotection:
Magnesium protects against oxidative stress and inflammation, which are often elevated in neurodivergent individuals and can impair executive function (Barbagallo & Dominguez, 2010).
Why Magnesium Glycinate?
Magnesium glycinate is a chelated form of magnesium, where the mineral is bound to glycine, an amino acid. This formulation is known for its high bioavailability and ability to cross the blood-brain barrier, making it particularly effective for cognitive and neurological support.
Unique Benefits of Magnesium Glycinate
- Enhanced Absorption:
Magnesium glycinate is absorbed more efficiently than other forms such as magnesium oxide or citrate, ensuring higher serum magnesium levels (Schuette et al., 1994). - Calming Effects:
Glycine has intrinsic calming and anti-anxiety properties, complementing magnesium’s role in stress reduction. - Minimal Gastrointestinal Side Effects:
Unlike some forms of magnesium, glycinate is less likely to cause diarrhea, making it suitable for long-term use. - Synergistic Action:
The combination of magnesium and glycine enhances the supplement’s ability to promote relaxation, improve sleep quality, and support focus.
Clinical Evidence Supporting Magnesium for Neurodivergence
Numerous studies highlight the potential benefits of magnesium for cognitive function and mental fatigue, particularly in neurodivergent populations.
1. Magnesium Deficiency and ADHD
A study published in Magnesium Research found that children with ADHD were significantly more likely to have low magnesium levels compared to neurotypical controls. Supplementation improved attention and reduced hyperactivity in this group (Nogovitsina & Levitina, 2007).
2. Magnesium and Anxiety Reduction
A meta-analysis in Nutrients reviewed the effects of magnesium supplementation on anxiety, concluding that magnesium significantly reduced symptoms of generalized anxiety and stress. This effect is particularly relevant for neurodivergent adults who often experience comorbid anxiety disorders (Boyle et al., 2017).
3. Magnesium and Cognitive Fatigue
Research in Nutrients demonstrated that magnesium supplementation improved energy metabolism in the brain, reducing cognitive fatigue and enhancing focus during prolonged mental tasks (Zhang et al., 2018).
4. Glycine for Neuroprotection
A study in Frontiers in Behavioral Neuroscience highlighted glycine’s role in promoting inhibitory neurotransmission and reducing excitotoxicity, supporting its use in conditions characterized by overstimulation and difficulty focusing (Rahman, 2020).
5. Combined Effects of Magnesium and Glycine
A clinical trial in Journal of Research in Medical Sciences found that magnesium glycinate supplementation improved sleep quality, reduced stress, and enhanced cognitive performance in individuals with sleep-related fatigue (Abbasi et al., 2012).

Practical Applications for Magnesium Glycinate in Neurodivergent Adults
Integrating magnesium glycinate into daily routines can help neurodivergent adults manage focus, mental fatigue, and executive function challenges. Below are practical strategies for its use:
1. Daily Supplementation
- Dosage: The recommended daily allowance (RDA) for magnesium is 310–420 mg for adults, depending on age and sex. Neurodivergent individuals may require slightly higher doses due to increased metabolic demands.
- Timing: Magnesium glycinate is best taken in the evening to leverage its calming effects and improve sleep quality, which indirectly enhances focus during the day.
2. Dietary Sources
- Combine supplementation with magnesium-rich foods such as spinach, nuts, seeds, and legumes to support overall magnesium levels.
3. Stress Management
- Pair magnesium glycinate with relaxation techniques like mindfulness or yoga to amplify its calming effects.
4. Sleep Support
- Use magnesium glycinate as part of a bedtime routine to improve sleep quality, which is essential for reducing mental fatigue and enhancing focus.
5. Monitoring and Adjustment
- Track improvements in focus, energy levels, and executive function to determine the effectiveness of supplementation and adjust dosage as needed.
Safety and Considerations
Magnesium glycinate is generally safe and well-tolerated. However, excessive intake can cause mild side effects, such as nausea or abdominal cramping. Individuals with kidney disease or those taking medications that affect magnesium levels should consult a healthcare provider before supplementation.
Potential Drug Interactions
- Magnesium may interfere with the absorption of certain medications, including antibiotics and bisphosphonates. It is recommended to take magnesium glycinate at least two hours apart from these drugs.
Future Research Directions
While existing studies support magnesium’s role in cognitive health, further research is needed to explore:
- The specific effects of magnesium glycinate on executive function and focus in neurodivergent adults.
- Long-term outcomes of magnesium supplementation in managing cognitive fatigue and attention regulation.
- Synergistic effects of magnesium glycinate when combined with other cognitive-supporting nutrients, such as omega-3 fatty acids or B vitamins.
Such studies could provide deeper insights into magnesium glycinate’s potential as a cornerstone supplement for neurodivergent individuals.
