I am not a chemist, and do not claim to be an expert in magnesium by any means. There are some great websites that I have linked all over CWE, so just as I did, you can go research this wonderful mineral.
I do think that the timespan would be different for each person. How well it is being absorbed, what type of magnesium is being used, size of body etc.
When you ask how much is too much... when you don't like the formation of your stool, I would think you are on the High side and can back off a bit. Magnesium is not stored in the body, and there have been no toxic side effects that I have ever read about.
As I stated before though, the blood test only shows how much of the mineral you have in your blood, not how much has crossed the blood brain barrier. Your test might show that you are within range (as my daughters did) but she is being helped by taking it and more than the RDA.
Are you saying that they are putting magnesium in the Mysoline?
If this is so do you know what type they add?

RobinN, does that elemental analysis measure all elements or specific ones that are requested? I've never heard of that type of test.[/QUOTE]
It is what was requested by a specialist that I went to. This was at a very critical time for Rebecca, when I was having difficulty finding decent help in a timely manner. Dr Reiss was/is a dream doctor... and he tested for Toxic Elements and Nutrient Elements from:

You could contact them and see if this is a standard test or one that is individualized. He also requested hormone levels from another independent lab.
I use these test results in a lot of my research. I found from this that she is high mercury, antimony, and tin. Many doctors don't know how to read these tests, but I did find a well respected chemist, online - Andrew Cutler, that has been able to shed some light on the test results.
