A member asked:
Magnesium blood level was 2.5. all other electrolytes normal & normal kidney functioning. not on any supplements/meds containing mag. is this bad?

Serum useless: A serum magnesium level is not very helpful. The body keeps serum magnesium under very tight control at the expense of tissue/bone levels. Check an rbc magnesium level instead to get a better picture of tissue levels. Ideal levels in the upper half of reference range. Most people are low.
