I did potassium/calcium serum test and was wondering if they could indicate magnesium deficiency, there's no option but mg serum/urine and it's not accurate as i know. what you drs think?

Check of serum level: of Magnesium. this is an easy test for your doctor to order.

Nobody knows: Magnesium is by far our least-understood major ion as it's almost entirely intracellular and nobody knows how to test for it. What I do know is that all the "pop" claims are subscientific. You're 19 years old, Adam, at your prime both in terms of athletic and learning capacity.
