Migraines, a debilitating neurological condition, impact over one billion people globally, according to the World Health Organization (WHO). Among those affected, a significant proportion experience migraine auras—neurological disturbances that often precede or accompany migraine attacks. These auras may involve visual distortions, sensory disruptions, or speech difficulties, creating additional challenges for sufferers.
While medications exist to treat migraines, many individuals seek alternatives to reduce the frequency and severity of their symptoms. One supplement gaining attention for its potential benefits is magnesium glycinate. As a highly bioavailable form of magnesium, it shows promise in supporting neurological health and addressing migraine-related complications. This article explores the science behind magnesium glycinate and its potential role in easing migraine auras for chronic sufferers.

Understanding Migraine Auras and Their Triggers
Migraine auras are transient neurological symptoms that typically last between 5 and 60 minutes. They manifest in about 25–30% of individuals with migraines, often serving as a precursor to the headache phase. Common characteristics of auras include:
- Visual Disturbances: Flashing lights, blind spots, or zigzag patterns in the visual field.
- Sensory Symptoms: Numbness or tingling, typically affecting one side of the body.
- Speech or Language Impairment: Difficulty finding words or forming coherent sentences.
Research published in The Lancet Neurology indicates that auras result from cortical spreading depression (CSD)—a wave of electrical activity in the brain followed by a period of neuronal suppression. This phenomenon is linked to changes in brain chemistry, vascular function, and neuronal excitability.
Triggers for migraine auras often overlap with those for migraines and may include:
- Stress: Emotional or physical stress can precipitate migraines and their auras.
- Hormonal Fluctuations: Changes in estrogen levels, particularly during the menstrual cycle, often influence migraines.
- Dietary Factors: Certain foods, such as aged cheese, caffeine, or alcohol, may act as triggers.
- Sleep Disturbances: Insufficient or irregular sleep patterns can exacerbate migraine symptoms.
- Nutritional Deficiencies: Magnesium deficiency, in particular, has been implicated as a common factor in chronic migraines and auras.

Magnesium and Its Role in Neurological Health
Magnesium is a vital mineral involved in over 300 enzymatic reactions within the body. Its functions include:
- Regulating Neurotransmitter Activity: Magnesium helps balance excitatory and inhibitory neurotransmitters, preventing overstimulation of the brain.
- Maintaining Vascular Health: The mineral supports vascular tone and reduces the risk of blood vessel constriction—a key factor in migraines.
- Reducing Neuroinflammation: Magnesium modulates inflammatory markers like interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α), which are often elevated in migraine sufferers.
- Protecting Against Cortical Spreading Depression: Magnesium’s role in neuronal excitability may counteract the wave-like electrical disturbances associated with migraine auras.
Studies suggest that magnesium deficiency is more prevalent among individuals with migraines. A review in The Journal of Headache and Pain reported that serum and cerebrospinal magnesium levels were significantly lower in those with chronic migraines compared to non-migraine sufferers.
Why Magnesium Glycinate?
Magnesium glycinate is a chelated form of magnesium bound to glycine, an amino acid. This form is particularly advantageous for migraine sufferers due to:
- High Bioavailability: Magnesium glycinate is highly absorbable, ensuring efficient delivery to target tissues, including the brain.
- Minimal Gastrointestinal Side Effects: Unlike magnesium oxide or citrate, magnesium glycinate is gentle on the stomach, making it suitable for long-term use.
- Calming Effects: Glycine has soothing properties, reducing stress and promoting relaxation—factors that can mitigate migraine triggers.
These attributes make magnesium glycinate an appealing option for addressing the complex pathways involved in migraine auras.

Clinical Evidence Supporting Magnesium for Migraines
Several studies highlight magnesium’s efficacy in reducing the frequency and severity of migraines, including those with auras:
1. Preventing Migraine Auras
A randomized controlled trial published in Cephalalgia evaluated the impact of magnesium supplementation on individuals with aura-prone migraines. Participants who received 600 mg of magnesium daily experienced a 41.6% reduction in aura frequency over 12 weeks compared to a placebo group.
2. Shortening Aura Duration
Research in Headache: The Journal of Head and Face Pain demonstrated that magnesium supplementation reduced the duration of migraine auras by 25%, providing relief to chronic sufferers.
3. Addressing Underlying Deficiencies
A study in The Journal of Neurology found that correcting magnesium deficiency significantly decreased migraine intensity and improved quality of life in participants. Those with the lowest baseline magnesium levels showed the most substantial improvement.
4. Reducing Inflammatory Markers
Magnesium’s anti-inflammatory effects may benefit migraine patients. A clinical trial in Nutrients reported that magnesium supplementation lowered IL-6 and TNF-α levels, reducing the inflammatory cascade associated with migraines.

Integrating Magnesium Glycinate into a Migraine Management Plan
1. Dosage Recommendations
The recommended dietary allowance (RDA) for magnesium is:
- Adult men: 400–420 mg/day
- Adult women: 310–320 mg/day
For migraine prevention, therapeutic doses typically range from 300 to 600 mg/day. Magnesium glycinate’s superior absorption allows for effective supplementation within these ranges. However, consultation with a healthcare provider is essential to tailor the dosage to individual needs.
2. Pairing with Other Nutrients
Magnesium glycinate works synergistically with:
- Riboflavin (Vitamin B2): Shown to reduce migraine frequency in clinical studies.
- Coenzyme Q10 (CoQ10): Supports mitochondrial health, addressing one of the potential root causes of migraines.
- Vitamin D: Enhances magnesium absorption and modulates immune responses.
3. Lifestyle Modifications
To maximize the benefits of magnesium glycinate, individuals should incorporate lifestyle changes, including:
- Maintaining a Regular Sleep Schedule: Consistent sleep patterns can reduce migraine occurrence.
- Practicing Stress Management: Techniques such as yoga, meditation, and biofeedback help manage emotional triggers.
- Avoiding Known Triggers: Keeping a migraine diary can help identify and minimize exposure to dietary or environmental triggers.

Dietary Sources of Magnesium
While supplementation is effective, incorporating magnesium-rich foods into the diet provides additional benefits. Examples include:
- Leafy Greens: Spinach, kale, and Swiss chard.
- Nuts and Seeds: Almonds, cashews, sunflower seeds, and pumpkin seeds.
- Whole Grains: Brown rice, quinoa, and oatmeal.
- Legumes: Black beans, lentils, and chickpeas.
- Fish: Mackerel and salmon.
Future Research Directions
Although existing evidence supports magnesium’s role in migraine management, further research is needed to explore:
- Long-Term Effects of Magnesium Glycinate: Assessing safety and efficacy over extended supplementation periods.
- Combination Therapies: Investigating magnesium glycinate alongside other treatments, such as biofeedback or pharmacological interventions.
- Mechanisms of Action in Auras: Exploring magnesium’s direct impact on cortical spreading depression and neuronal excitability in human models.
Conclusion: A Promising Ally for Migraine Sufferers
Magnesium glycinate represents a promising, evidence-based option for individuals seeking relief from migraine auras. By addressing magnesium deficiency, reducing neuroinflammation, and supporting vascular and neuronal health, this highly bioavailable supplement targets the root causes of migraines and their auras. Combined with dietary strategies and lifestyle modifications, magnesium glycinate offers a comprehensive approach to migraine management.
For chronic sufferers, integrating magnesium glycinate into a personalized care plan may provide a pathway to fewer, less severe episodes, improving both neurological health and overall quality of life. Continued research and clinical exploration will further illuminate magnesium glycinate’s role in alleviating migraines and associated auras.
