Hi Daniel - thank you for this article. I have spent many years researching, and using magnesium, and I would strongly suggest you read The Magnesium Miracle by Dr. Carolyn Dean.

Not only is her book excellent, but her magnesium is the one that worked for me. None of the over-the-counter tablets did anything.

The thing too is that, depending on the level of your deficiency, you may need to take more at first. Her products are not cheap, but they are the best I have found.
