Key Takeaways
Emerging evidence suggests a neuroprotective role of magnesium in neurological and cognitive function
Magnesium may preserve cognitive function and reduce dementia risk
Results from a large 2023 study found that higher dietary magnesium intake was strongly associated with larger brain volumes and lower white matter lesions (WML).
Magnesium intake of ≥ 550 mg/day is predicted to result in approximately 0.20% larger grey matter, and 0.46% larger right hippocampus compared to an intake of ~350mg/day.
These effects were more evident in women than men.
Research has clearly demonstrated the wide-reaching therapeutic role of magnesium in supporting a range of body systems.1 Magnesium is involved in over 300 biochemical enzymes and has many physiological functions, including energy and protein production, glucose metabolism2 , and immune regulation.3 This essential mineral is also well-known for its key role in musculoskeletal health, with magnesium supplementation found to improve bone mineral density4 , reduce muscle soreness5 , and support muscle cramps.6
In addition to magnesium’s existing wide range of benefits, emerging evidence suggests a protective role of magnesium in neurological and cognitive function.7
