Magnesium rich foods

Is your doctor doing the right magnesium test?

When it comes to magnesium, there isn’t a perfect test, but there is a better test than the one used most often.

There are two tests that are generally available, a serum magnesium and an RBC magnesium.

Serum magnesium is the test most often used because it’s cheaper (by about $5 to $10), but it is the last to reveal a magnesium deficiency.

What that means is, by the time your serum magnesium is low, you are already severely depleted in magnesium. At that point you are at risk for serious illness, like pancreatic cancer.

We want to catch a magnesium deficiency earlier and we can with the RBC magnesium test.

I have yet to see anyone with an ideal RBC magnesium. It might be in the normal lab range, but it is not in the optimal range.

Magnesium is quickly depleted with stress and with vitamin D supplements, so a deficiency is way more common than you think.

Next time you have lab work done, ask for an RBC magnesium, and make sure you specify RBC. You can do the serum as well, but you either need both or just the RBC.

Magnesium depletion can lead to diabetes, heart issues, neurological issues, sleep issues, weight gain or the inability to keep the weight off, and more.

An RBC magnesium is not a ‘nice to have,’ it’s a ‘need to know’ test.

You don’t want the serum magnesium below 2.0 mg/dl and you don’t want the RBC magnesium below 6.5 mg/dl.

Of course, your doctor won’t think it’s a problem if it’s in the normal lab range, which is above 1.6 mg/dl for a serum magnesium and above 4.2 mg/dl for an RBC magnesium.

Can you see how you can feel like crap when your labs are “normal?”

Don’t wait until you are so depleted you feel like death warmed over. Check your magnesium!
