anemia
"I was severely anemic, with muscle cramping throughout my body. Restless legs at night and tingling in my fingers. I had chest pain, and my memory and focus were off.  All of my symptoms completely disappeared and I could sleep through the night for the first time in years.  I regained my energy and felt alive again. I had no side effects at all.  Saw immediate results.  I took one pill twice a day, with orange juice."
