Natural Calm, 16 ozstar rating 5Debra PalmerJanuary 28, 2010I suffer greatly from Fibromyalgia, accompanied by degenerative disc disease and have anemia from an ulcer. This supplement alone helps greatly improve my energy levels and sense of well being. I have taken Magnesium in caplet form. This is light years faster acting and anyone who uses it can absolutely tell a difference before finishing an 8 oz. container.
