For years I was feeling terrible: face flushing, anxiety, trouble sleeping, fatigue, Dizziness and more. My doctor tried me on a few different psyche meds but I never really felt back to 100% and sometimes even felt worse. I did some research and learned about Magnesium deficiency and asked the doctor about it. He said if I was taking a multi vitamin that should be all I need and if vitamins worked so well "then everyone would be taking them." So I just decided to take matters into my own hands and found this vitamin online. After a couple weeks of taking it I noticed a decrease in my issues and after a month or more was feeling so much better. The Zinc also helps prevents colds and I used to be a 3-5 cold person per winter. Now I might get one cold each winter. I think this supplement has helped tremendously. 3 years now and I don't take any of those horrible meds and I feel great. Horray for self diagnosing and the internet!!
