Higher magnesium intake (over 407 mg/day) was linked to better overall brain function in mentally healthy older adults, but this benefit was only observed in women.

“A study involving over 6,000 adults aged 40-73 found that participants with a daily intake of 550 mg or more had larger gray matter and hippocampal volumes, akin to one year younger.”

“who reported a higher magnesium intake had on average larger brain volumes which could convey up to approximately one year of reduced brain aging compared to those with lower magnesium intakes so the results revealed that so the higher dietary magnesium consumption this was about 550 milligrams per day seem to correlate with larger gray matter and hippocampal volumes than the average intake of about 350 milligrams per day which is actually closer to the RDA um this was actually particularly notable in women”

“to really I would say conclusively say state that magnesium is improving brain health by increasing brain volume particularly gray matter in the hippocampal Regal of the brain we would need clinical trials you know to substantiate that potential relationship”

“another observational study this was 2 thou over 2,500 older adults who are mentally healthy again found higher magnesium intake this was over 407 milligrams per day was also linked to overall better brain function um but this benefit was actually only seen in women”
