Magnesium is particularly important for protecting the brain however intestinal absorption problems can make it difficult for many conditions to obtain enough from diet or supplements. Protein and phospholipids are also necessary for the brain fluid to have reserve supplies of magnesium as it is an electrically active ion and can not be available in excess as a free ion, instead adequate back stock is held by protein or phospholipid molecules. When bound it is not electrically active but can quickly be released if needed to protect the brain or other cells in case of trauma. For more information, food and dietary and topical supplement forms of magnesium see: To have optimal Magnesium needs Protein and Phospholipids too.
