A new study recently came out about Magnesium.
You can read it here: Dietary magnesium intake is related to larger brain volumes and lower white matter lesions with notable sex differences
550mg of Magnesium a day reduces brain shrinkage and prevents cognitive decline (like dementia).
This is not the first, in fact there are many studies showing Magnesium’s positive effect on the brain and cognition. Often times the benefits of Magnesium are compounded with Vitamin D or other nutrients. This is why I recommend everyone take a Magnesium in addition to a multivitamin.
You should make sure your Magnesium is in the forms of Magnesium Glycinate or Magnesium Threonate and that it is from a professional grade company (clean and quality assured), such as these in my Full Script store.
