Was using to relieve nerve pain in my back! It absolutely helped relieve some pain and helped me sleep through the night, as I keep awakening from the pain, I've also noticed that my bones don't crack anymore I'm able to bend down easily and don't hear any bones cracking, once I ran out I tried a different brand and it just doesn't work the same so I will be going back to this brand also I've noticed brighter skin and teeth not sure if it has anything to do with the magnesium but that's the only supplement I'm taking right now, I'm so grateful for your magnesium didn't know I needed it! I feel so much better and it's easy to grab right at cvs
