After years of problems sleeping, being more tired in the morning than when I went to bed, and continual headaches, I am pleased to say that this liquid magnesium supplement changed my life. I sleep better at night, have almost zero headaches and magnesium chloride naturally helps to keep the digestive/waste system regular. Maybe that is too much information, however in this day with high rates of constipation and other bowel trouble, it is important that things keep moving smoothly. I was highly satisfied with the speed in which I received my order as well. Thank you!
