My husband has been taking Magnesium Glycinate 400 mg (elemental Mg. ) ( 3 caps) per day, essentially for lowering BP and Cholesterol.. I also got him "Transdermal Magnesium" Oil (from the Book per Dr. M. Sircus ) 8 sprays rubbed to each leg at night, he also uses the spray to his upper body in the mornings after shower.. I noticed after a few weeks that he stopped grinding his teeth, and also stopped snoring.. :) :) I googled "Magnesium and snoring" and found Dr C. Dean's website on Magnesium that states Magnesium treatment should be the first treatment of choice for Sleep Apnea before resorting to CPAP or surgeries. I have a few family members and friends who were advised CPAP and or surgery for sleep apnea and I hope Magnesium treatment as above will help the many many more people out there who are having these problems. What she has on her website is Magnesium Citrate powder 300 mg twice a day.. Mg Citrate could cause loose stools vs Mg Glycinate which does not.. I wish this helps someone.
