Magtein-based formula improved memory and cognition in healthy adults
A double-blind, placebo-controlled trial in 109 healthy Chinese adults aged 18-65 found that a magnesium L-threonate (Magtein)-based formula produced significant improvements over placebo in all five subcategories of a standardized clinical memory test, and in overall memory quotient scores, after 30 days - with older participants showing more improvement than younger ones.
Human RCTMMFS-01 (magnesium L-threonate) improved overall cognitive ability in older adults
A randomized, double-blind, placebo-controlled trial in adults aged 50-70 with cognitive impairment found that 12 weeks of MMFS-01, a magnesium L-threonate compound, significantly improved a composite score of overall cognitive ability compared with placebo, with the largest gains in executive function.
Human RCTReview describes magnesium L-threonate among the more bioavailable forms for neuronal health
A 2024 review of magnesium's role in neuronal health describes magnesium-L-threonate (MgLT) and other bioavailable magnesium compounds as having shown promising results in enhancing synaptic density, improving memory function and alleviating symptoms of mental health disorders, while calling for further research.
ReviewFoundational study: a new magnesium compound elevated brain magnesium and improved memory in rats
The study that first identified magnesium-L-threonate (MgT) found that raising brain magnesium with this compound enhanced learning, working memory, and short- and long-term memory in rats, and increased synapse density in the hippocampus that correlated with the memory improvements.
Preclinical studyThreonate itself was shown to directly raise intraneuronal magnesium in neuron cultures
A mechanistic study found that threonate - the amino-acid-like component of magnesium L-threonate - directly increased intracellular magnesium concentration in cultured hippocampal neurons and in human neural stem cell-derived neurons, upregulating synapse-related signaling in a way other magnesium salts did not replicate.
Preclinical studyElevating brain magnesium reversed synapse loss in an Alzheimer's mouse model
A study in a transgenic Alzheimer's disease mouse model found that magnesium-L-threonate treatment reduced amyloid-beta plaque, prevented synapse loss, and reversed memory decline, with benefits observed even when treatment began at a late stage of disease-like pathology.
Preclinical studyMagnesium-L-threonate improved deep and REM sleep in a 21-day trial
A randomized, double-blind, placebo-controlled trial in adults with self-reported sleep problems found that magnesium-L-threonate (1 g/day) improved deep sleep and REM sleep scores, daytime energy, mood and alertness, measured objectively with a sleep-tracking ring, compared with placebo over 21 days.
Human RCTMagnesium bisglycinate modestly reduced insomnia severity
A randomized, placebo-controlled trial in 155 adults with poor sleep quality found that 250 mg of elemental magnesium as magnesium bisglycinate (a different chelate than L-threonate) produced a small but statistically significant reduction in Insomnia Severity Index scores after 4 weeks compared with placebo.
Human RCTSleep quality scores improved alongside magnesium status in older adults
A controlled trial in adults over 51 with poor sleep quality found that Pittsburgh Sleep Quality Index scores improved and erythrocyte magnesium increased over 7 weeks, though the improvement occurred in both the magnesium-citrate and placebo groups, leaving magnesium's specific contribution unclear.
Human RCTCochrane review found no meaningful benefit for cramp prevention in older adults
An updated Cochrane review of 11 trials (735 participants) concluded that oral magnesium supplementation is unlikely to provide clinically meaningful cramp prophylaxis for older adults with idiopathic nocturnal leg cramps, though evidence for pregnancy-related cramps remained conflicting.
Cochrane ReviewMeta-analysis found no reduction in pregnancy leg cramp frequency
A meta-analysis of 4 randomized controlled trials (332 pregnant women) found that oral magnesium supplementation did not significantly decrease the frequency of leg cramps compared with control, and did not significantly improve recovery from cramps.
Meta-analysisObservational trial found no advantage over placebo for pregnancy leg cramps
A controlled trial of 130 pregnant women with leg cramps found a similar reduction in cramp frequency in both the oral magnesium citrate group and the placebo group after 4 weeks, with no significant difference between them.
Human RCTMagnesium acts as a cofactor in over 300 enzymatic reactions
A comprehensive review describes magnesium as a cofactor for more than 300 enzymatic reactions, essential for converting ATP to ADP for energy production, as well as for protein synthesis, DNA synthesis and muscle contraction throughout the body.
ReviewMagnesium is essential for ion channel function, nerve transmission and vasomotor tone
A review of magnesium's physiological roles describes its involvement as a cofactor in ATP metabolism and its role in regulating ion channels, muscular contraction, cardiac excitability, vasomotor tone, nerve transmission and neuromuscular conduction.
ReviewMagnesium is a required cofactor for activating vitamin D
A review found that the enzymes that metabolize vitamin D in the liver and kidneys all appear to require magnesium as a cofactor, linking adequate magnesium intake to the body's ability to properly activate and use vitamin D.
ReviewMeta-analysis found magnesium supplementation modestly lowered blood pressure
A meta-analysis of 38 randomized controlled trials (2,709 participants) found magnesium supplementation reduced systolic blood pressure by 2.81 mmHg and diastolic blood pressure by 2.05 mmHg compared with placebo, with larger reductions in those with hypertension or low magnesium status.
Meta-analysisDietary magnesium intake is inversely associated with cardiovascular risk factors
A review of electrolyte minerals and cardiovascular health found that, unlike sodium, dietary magnesium (along with potassium and calcium) shows an inverse correlation with cardiovascular events and risk factors, particularly blood pressure.
ReviewMagnesium reduced new-onset atrial fibrillation after cardiac surgery
A meta-analysis of 24 randomized controlled trials (3,373 participants) found that magnesium supplementation reduced the risk of new-onset atrial fibrillation following cardiac surgery, with high-certainty evidence in lower-bias trials, though it had no significant effect on all-cause mortality.
Meta-analysisUpdated review confirms magnesium's link to bone mineral density
An updated narrative review of 28 studies found that lower serum magnesium is associated with osteoporosis, that roughly a fifth of people consistently consume less magnesium than recommended, and that magnesium supplementation trials showed benefits for both bone mineral density and fracture risk.
ReviewHigher magnesium intake linked to higher hip bone mineral density in older adults
A systematic review and meta-analysis of studies in adults 60 and older found a significant positive association between magnesium intake and hip bone mineral density, though evidence for other bone sites and fracture outcomes was more limited.
Meta-analysisLower serum magnesium independently associated with osteoporosis risk
A retrospective study of 496 postmenopausal women found that lower serum magnesium levels were independently associated with higher odds of osteoporosis and osteoporotic fractures, after adjusting for age, BMI and other bone-turnover markers.
Observational studyModelling study estimates widespread inadequate magnesium intake worldwide
A global modelling analysis covering 185 countries found estimated inadequate-intake rates were higher for men than women for several nutrients including magnesium, part of a broader pattern of common micronutrient intake gaps worldwide.
Modelling StudyReview frames magnesium deficiency as an underappreciated public health issue
A 2025 review describes magnesium as a critical cofactor in hundreds of enzymatic reactions and links widespread low magnesium status - driven by inadequate dietary intake, chronic disease and lifestyle factors - to elevated risks across cardiometabolic, skeletal and neurological health.
ReviewReview estimates roughly a third of the global population falls short on magnesium
A 2025 review estimates that approximately 2.4 billion people, or about 31% of the global population, do not meet recommended magnesium intake levels, driven by modern dietary patterns, soil depletion and food processing losses.
