I had been reading the emails about Mag-Key, so I decided to research more about it. I read many of the reviews, and many of them talked about how it helped their anxiety and constipation, neither of which I have. I clicked on the chat window and began speaking to Liz. I told her that I didn't suffer from either of those issues so I asked her how could the product help me? She said, "It also helps your heart." Since I have a heart, I thought, "Well, why not? I'll order two bottles and if I don't like the results, I'll return the unopened bottle for credit." (I don't know why I would think I'd ever send anything back to UNI KEY Health because I never have before). I received the package on Friday, so I took two capsules that night. I woke up the next morning feeling so much better than I usually do. It was incredible! A few years ago, I had to wear an orthopedic boot for 6 months, due to a heel spur, and since then, when I stand in one place too long, or when I make my hour drive to work, my lower back gets stiff and hurts. On Saturday morning, the day after taking my first dosage of Mag-Key, I drove to work and didn't have the lower back pain and stiffness when I arrived. I just ordered another bottle of Mag-Key, even though I already have an unopened bottle. I want to make sure I don't run out! I STRONGLY recommend this product.
