hello, I am my mothers caregiver. she suffers from dementia, CHF, COPD, Diabetis, Osteo artheritis and takes medication for all of the above. recently she was taken to the ER for a fall. Blood work was done and CT Scan were all clear. She recently had a follow up appointment and more blood drawn. this time her Magnesium levels were low and her doctor recommended another trip to the ER for a magnesium infusion becasue her MD is concerned it the low level could affect her heart. Can her Magnesium levels be raised after some daily multi vitamins?
