Magnesium levels inside the cells can't be measured, unfortunately. Sometimes, you just have to take the supplement for awhile, and see if it helps. I've noticed that B12 makes me feel better sometimes, even when my B12 level is normal. I'm convinced that some of us just feel different than others, even if our lab values are normal. It's hard to believe that absolutely everyone can fall into the "normal range" and feel good.
I remember reading once that some well-known fibro doc said that people with fibro seem to get hypoglycemic feelings (sweating, increased heart-rate, etc.) even when their blood sugar is "normal".
This is true for me. I guess I'm just saying don't NOT try something because your labs were normal (providing taking extra isn't harmful).
