My miracle worker I am so very happy because my granddaughter told me about Twinlab Magnesium 400 mg. I bought my first bottle else where, then she told me about Swanson's order by Internet. I looked it up on the computer and then ordered a catalog. I will never be without this particular product again. I tryed one from the discount store, but I got no results at all. The Twinlab Magnesium worked perfect from day one. August 15, 2009
Magnesium for health I personally use these sparingly because they act on me quite easily. My wife uses these daily and they are a great help to her. Keeps her regular and feeling well. November 8, 2007
