Hi,
I am geeky enough to be bugged about not knowing why she is checking for magnesium.
I just found that low magnesium can be a symptom of Addison's Disease ( When the adrenal glands are not producing enough hormones.) . . . So she was looking to find out why you have low energy.

Some of us here take magnesium -- At the moment, I can't remember why exactly -- today was a difficult day for my brain.
