Magnesium Deficiency & the Sublingual Epithelial Test
(Kitty Hawk, NC)
I have been taking Mg supplements for years and have classic symptoms of low Mg. I take high quality brands from Source Naturals, Jarrow, Doctor's Best, etc., yet still have to take Magnesium from morning until night to prevent twitching in calves, anxiety, irregular heart beats, etc.
Serum Magnesium was 1.63 mEQ/L in the morning after I had already taken probably 50 - 75 % of the RDA prior to the test and had been taking Mg daily in large dosages for probably more than 10 years before the test. My PTH and calcium are normal, as are all values on the Basic Metabolic Panel. I have been to a cardiologist and EKG and ECHO tests are normal. Blood sugar is normal, HA1C = 4.7, TSH = 1.57. I exercise regularly but have learnrd to take Magnesium prior to beginning exercise (50 % of RDA) to prevent problems with irregular heartbeats.
I think that I am a candidate for the sublingual epithelial test. Does a doctor need to order it? I don't think that my primary care doctor knows about it, and it probably is unavailable through my insurance. Do you have any suggestions about how to go about getting the test? Is the sublingual epithelial test expensive?
