In individuals with normal renal function, magnesium deficiency can be assumed and treated if symptoms like low bone density, premature ventricular contractions, skipped heartbeats, or cramps are present.

“which is in a person with normal renal function you tend to air on the side of assuming people are magnesium deficient and if you have any reason to believe it based on symptoms and or signs right so low bone density uh you know preventricular contractions so you know um relatively benign skipped heartbeats things of that nature cramps that would be a very common thing that would give you reason to believe a person is magnesium deficient we just go ahead and replace the Magnesium anyway”
