Magnesium is a fundamental mineral involved in over 300 enzymatic reactions in the body. From energy production to neurotransmitter function, magnesium is essential for maintaining physiological and neurological health. Yet, despite its importance, many individuals do not consume adequate amounts, leading to a range of neurological disturbances, including sleep disorders and cognitive decline.
One form of magnesium that stands out in terms of absorption and bioavailability is magnesium bisglycinate. This article explores the unique advantages of this form, its impact on sleep and cognition, and how it differs from other magnesium compounds from a chiropractic neurology standpoint.
The Essential Role of Magnesium in Neurological Health
Magnesium plays a critical role in the nervous system, influencing neurotransmitter regulation, neuronal excitability, and synaptic plasticity. These functions directly impact sleep quality, learning, memory, and overall cognitive performance. Magnesium deficiencies have been linked to various neurological conditions, including anxiety, depression, insomnia, and neurodegenerative diseases such as Alzheimer’s and Parkinson’s.
Neurotransmitter Regulation
Magnesium modulates neurotransmitters such as glutamate and gamma-aminobutyric acid (GABA), which influence brain excitability. While glutamate is the primary excitatory neurotransmitter, GABA acts as an inhibitory neurotransmitter, promoting relaxation and sleep. Magnesium helps maintain a balance between excitation and inhibition, preventing excessive neuronal firing that can lead to anxiety, poor sleep, and cognitive dysfunction.
Sleep Regulation
Sleep disturbances are common in individuals with magnesium deficiencies. Magnesium facilitates the production of melatonin, the hormone responsible for regulating circadian rhythms. Additionally, it has been shown to enhance slow-wave sleep, the most restorative phase of the sleep cycle.
A study published in Journal of Research in Medical Sciences found that elderly individuals supplemented with magnesium experienced improved sleep efficiency, longer sleep duration, and reduced sleep onset latency (Abbasi et al., 2012). These findings suggest that maintaining optimal magnesium levels can contribute to better sleep quality.
Cognitive Function and Neuroprotection
Magnesium is vital for cognitive function, particularly in memory formation and learning. It influences synaptic plasticity, which is the ability of neural connections to strengthen or weaken over time in response to activity. Low magnesium levels have been associated with cognitive decline and an increased risk of neurodegenerative diseases.
In a study published in Neurobiology of Aging, researchers found that magnesium supplementation improved synaptic density and cognitive function in aging rodents (Slutsky et al., 2010). These results suggest that adequate magnesium intake may help preserve cognitive function as individuals age.
Magnesium Bisglycinate: A Superior Form for Neurological Health
Not all magnesium supplements are created equal. Magnesium bisglycinate, a chelated form where magnesium is bound to two glycine molecules, offers distinct advantages over other forms of magnesium:
Enhanced Absorption and Bioavailability
Many magnesium supplements, such as magnesium oxide, have low bioavailability due to poor intestinal absorption. Magnesium bisglycinate, however, is highly absorbable because the glycine chelation protects it from competing minerals and enhances transport across the intestinal wall. A study comparing various magnesium compounds found that magnesium bisglycinate exhibited superior absorption compared to magnesium oxide and magnesium citrate (Coudray et al., 2005).
Reduced Gastrointestinal Discomfort
One common side effect of magnesium supplementation is gastrointestinal distress, including diarrhea. Magnesium citrate and magnesium oxide, for example, have laxative effects due to their osmotic properties. Magnesium bisglycinate, on the other hand, is less likely to cause digestive issues, making it a more tolerable option for individuals with sensitive stomachs.
Synergistic Effects with Glycine
Glycine, the amino acid bound to magnesium in this compound, serves as an inhibitory neurotransmitter in the central nervous system. Glycine has been shown to improve sleep quality by enhancing the ability to fall and stay asleep. It also has neuroprotective effects, making magnesium bisglycinate a particularly effective supplement for supporting both cognitive function and sleep.
Comparing Magnesium Bisglycinate with Other Magnesium Forms
Magnesium Citrate
Magnesium citrate is a popular form due to its relatively good absorption. However, it acts as a laxative at higher doses, which can limit its use for neurological benefits. While it may be effective for individuals dealing with constipation, it may not be the best choice for those seeking cognitive and sleep-related benefits.
Magnesium Oxide
Magnesium oxide contains a high percentage of elemental magnesium, but its absorption rate is poor. Studies have found that less than 10% of the magnesium from magnesium oxide is absorbed into the bloodstream. This makes it one of the least effective forms for improving neurological function.
Magnesium L-Threonate
Magnesium L-threonate has been studied for its ability to cross the blood-brain barrier, making it particularly promising for cognitive enhancement. However, it is relatively expensive and less commonly available compared to magnesium bisglycinate. While it may have specific cognitive benefits, magnesium bisglycinate remains the better option for those seeking a balance of cognitive and sleep support with superior absorption and tolerability.
Practical Recommendations for Supplementation
For individuals looking to improve sleep quality and cognitive function, magnesium bisglycinate supplementation can be an effective strategy. Here are some practical guidelines:
- Dosage: A common dose ranges from 200 to 400 mg of elemental magnesium daily. However, individual needs vary, and consulting a healthcare provider is recommended.
- Timing: Taking magnesium bisglycinate in the evening may enhance its sleep-promoting effects. Consuming it with food can improve absorption.
- Dietary Sources: While supplementation is beneficial, consuming magnesium-rich foods such as leafy greens, nuts, seeds, and whole grains can further support optimal levels.
Magnesium bisglycinate offers a compelling combination of enhanced bioavailability, gastrointestinal tolerability, and neurological benefits. From supporting neurotransmitter balance to improving sleep efficiency and cognitive function, this form of magnesium stands out as a superior option for individuals looking to optimize their neurological health.
For those seeking a natural way to enhance sleep and cognition, magnesium bisglycinate provides a scientifically backed, well-absorbed, and well-tolerated solution. Incorporating this form of magnesium into a daily wellness routine can be a valuable step toward improved neurological function and overall well-being.

BPPV is more common than not following head trauma, with a higher likelihood of multiple canal involvement, recurrence, and prolonged recovery. Understanding the link between concussions and BPPV is crucial for effective diagnosis and treatment, particularly in chiropractic neurology and vestibular rehabilitation settings. Tailored treatment approaches, including vestibular exercises and repositioning maneuvers, are essential for helping post-traumatic BPPV patients regain balance and reduce symptoms.
Chiropractic Neurology Treatment Options
Chiropractic neurologists focus on non-invasive, drug-free treatments to manage BPPV, emphasizing patient-specific therapeutic maneuvers and vestibular rehabilitation:
- Vestibular Rehabilitation Therapy (VRT): Customized exercises aim to improve balance and reduce dizziness by promoting central nervous system compensation for vestibular deficits.
- Patient Education: Educating patients about BPPV, its triggers, and preventive strategies is crucial for effective management and reducing recurrence.
- Lifestyle Modifications: Advising patients on modifying daily activities to avoid provoking positions can help manage symptoms.
