I have had thyroid problems for a while. I have struggled with food sensitivities, blood pressure, joint pain, anxiety, heart palps, etc. I have taken the med for the thyroid, removed gluten, soy and caffeine. I have done all I knew to do. I joined a Facebook page for a NaturoPath doc and kept seeing magnesium pop up. I was super low on VIt D, at a level of 19. My sodium was low and it caused fatigue, dizziness, joint pain, Chest pain, heart palps, headaches, etc. I am ONLY 34 years old and I hate being sick and going to doctors. I don't want to be down unless I CHOOSE TO be lazy. I had been to the doctor because I was afraid I was going to have a heart attack, or because my blood pressure was crazy (never had the problem until a month ago). I was defeated, scared and just plain old afraid. I came home from work the day this arrived on my doorstep. I read about magnesium for a while before I dug into this, and read and researched them all before I ordered this one. I ordered two bottles to get free shipping. I prayed and cried and just wanted to feel better. The very day this arrived on my doorstep I felt so bad, and I knew I was going to miss 2 of my 3 kids school function. When I walked into the door I said "I am going to try this now." I got my hot water in a coffee mug, dumped 1/2 tspn into it and drank it. 5 minutes later my hot flash, flushed face, Chest pain and heart palps were GONE!!! 15 minutes later I felt good!!! I seriously felt good. I attended the kids school function and not only did I just go to sit in the car until it was over and pick them up to take them home...I went into it!! I participated!!! The crowd wasn't scary. I was alert, calm and so thankful for feeling good for the first time in 2 or 3 weeks. I will not be without this ever!! I will mention that 1.5 teaspoons is right for me and taking it in the morning and around lunch is perfect. Any more than this I do run to the restroom. So do not dive in at 2 teaspoons. I will make you go..
