Magnesium Testing – Determining Nutritional Deficiencies Carolyn Dean MD ND

I don’t necessarily think a person needs to have their magnesium levels tested before taking magnesium. It’s a very safe mineral that does not build up in the body. If you take “too much” magnesium, you will just get the laxative effect that eliminates the excess. Sometimes our customers report that they have asked their doctor if they can take magnesium and the doctor just says no – mostly because they don’t know the benefit and how to recommend a particular type or dose. But, sometimes, the doctor will say okay and will do a standard serum magnesium test which usually turns up normal and then retract the recommendation because ‘the test is normal’.

Serum magnesium is a very inaccurate measurement of magnesium in the body. Magnesium in the blood stream, AKA serum magnesium, measures only 1% of the total body magnesium; the range is 1.8-3.6mg/dL. When serum magnesium drops, mechanisms in the body push the levels up by dragging magnesium out of the bones and muscles. This is done for a very important reason – the heart muscle requires a constant level of magnesium or it will go into spasm – AKA a heart attack!

A somewhat better test is the Magnesium RBC. It may measure 40% of the body’s total magnesium. The range is 4.2-6.8mg/dL. But don’t be fooled into thinking that if your level is 4.2 you have enough magnesium. Someone recently wrote asking my source for the optimum range of magnesium being 6.0-6.5mg/dL. He asked if this tighter range come from research, or did I arrive at it empirically. He also said that his nutritional-metabolic doctors were unaware of using 6 as the floor instead of 4.

Empirically means: Verifiable or provable by means of observation or experiment. Yes, I arrived at this level empirically. Since 80% of the population is deficient in magnesium and since the lab ranges are taken from the general population – I don’t want to be lumped into the deficient 80%, I want my magnesium levels to be in the top 20th percentile, which is 6.0 and above.

In the past year, the Magnesium RBC range has dropped even lower – as the magnesium-deficient population grows!! In some labs the range is now 3.8-6.4. It’s quite devastating for someone who has atrial fibrillation, migraines, insomnia, muscle twitching – all the symptoms of magnesium deficiency to be told that 3.8mg/dl of Magnesium RBC is NORMAL and they are just fine – don’t bother with magnesium, just take these 6 drugs for your symptoms.

Being instructed to achieve magnesium saturation to counter magnesium deficiency is VERY NEW and a mostly unrecognized approach in allopathic medicine and functional doctors aren’t far behind. When magnesium is finally recommended, many are given the wrong forms. Most people cannot get enough magnesium to overcome their deficiency and the magnesium drain from drugs, stress and poor diet. If you do try to take saturation amounts of most magnesium products you can get the laxative effect long before your symptoms clear. That’s why I created ReMag, the non-laxative, fully absorbed magnesium.

On the other hand, there are other situations where a diagnostic test can be beneficial so we don’t want to throw the baby out with the bath water! Tonight on my radio talk show we will rightly divide those tests that are beneficial from those those that are not as you continue developing your own approach to natural health.

Please join us tonight for Magnesium Testing – Determining Deficiencies along with a wide range of health topics and safe solutions. You will love hearing the beneficial interactions with our callers and hosts alike including the body/mind connection, identifying the ‘conflict’ in the ‘conflict basis’ of disease and much more!!

    • Hello! Thank you Harris for your question – in my 9 years of working with Dr. Dean I have not seen a single person with a 7 score for magnesium UNLESS they took magnesium within a 24 hour window of their test! If you didn’t fast magnesium for at least 24 hours you may want to schedule that test again to get a more accurate reading! XO GINNEY

  1. If my fasting magnesium RBC comes in consistently (over, like, the past 4 – 5 years) at the high end of the range (over 6.0, generally at around 6.5), but I started having major magnesium “issues” over the past 18 months when my doctor put me on potassium supplements, including, oddly, peripheral neuropathy of the “heart hand” (left hand), then spreading to the other hand and the feet. It’s now constant, even though my RBC keeps testing high-normal. I’ve been on nighttime magnesium glycinate the whole time. Only when I went off the potassium (because, RBC-wise, I didn’t need it), did the symptoms get really bad. Now, I cannot sleep, my hands and feet scream all night, and I have tremendous flatulence and thirst, and peeing all night. I’m up to 1 tsp of the Remag during the day, but the neuropathy is not seeming to make any progress. What to do? I am beside myself witht the pain and exhaustion.

    • Hello, Sarah!

      GINNEY emailing you today.

      Sorry for the delayed response to this post. I am sure you’ve been back to your doctor and worked out your concerns. Please email if you need additional support.

  2. Hi… I hope the woman with the A fib does what you recommend because my Mom had A fib and she ended up having a heart attack and then a stroke quite young (she was very fit) I know she would not have died if she had been saturated properly. For me, It was only after a solid three months of taking 2 to 3 teaspoons a day of ReMag that I started to feel what you are calling saturated. I still take at least 2 teaspoons a day as I am eliminating the yeast/candida overgrowth that ended up in my brain.

  3. I took as much magnesium as my body could handle – so I often had the laxative effect but knew it was helping – this is before I started with ReMag. ReMag is the only supplement my body can get enough magnesium into it. I don’t think I am saturated yet and I haven’t taken any other supplements yet… I will get ReMyte today! I know for a fact Dr Dean’s supplements are working for me.
