Taking these tablets used to really relax the muscle rigidity, stiffness & spasms I experience as a result of of my medical condition but when they added other things to the capsules I have found them to be not as good at doing this as they once were. Now they have added magnesiun stearate & silicon dioxide to them. These tablets still put me to sleep but they are no longer the wonderful muscle relaxant they used to be...I am going to phase these tablets out and take a liquid form of magnesium chloride instead...I'm going to try Mega-Mag as I've read good things about it & it contains no fillers.

I’ve been using this for a while and have no complaints. Read more

the best chloride in the world, only this magnesium helps me sleep. Read more

Decades ago, I began having cardiac arrhythmias which were traced to excessive caffeine consumption. As I got older, the arrhythmias became severe and I was diagnosed with atrial fibrillation "afib." Still more recently, the problem became almost a daily one, and I went to an emergency room when my pulse suddenly went from 60 resting to about 120 without any exertion. This happened more and more often and I would take diltiazem to cause conversion back to normal heart rhythm. At the emergency room, where I had EKG, blood tests, etc., I advised the attending physician that I had decades earlier been diagnosed with afib. He said that the EKG indicated no afib, but ordinary tachycardia instead. They gave me cardizem and my heart rhythm returned to normal after about 30 minutes. The emergency room episode repeated a few days later and again, blood tests, EKG and a tachycardia diagnosis. And the physician also commented, quite as an aside, "BTW, your magnesium is low." You might want to take a supplement." No connection was indicated between my arrhythmias and the hypomagnesemia. I then referred to that "medical expert"--the internet. And guess what? Hypomagnesemia can cause SVT--supraventricular tachycardia. This was after 50 years of having an ever-increasing problem with, first, caffeine causing it. Then ibuprofen. Then echinacea. Then epinephrine inhaler for asthma. Then benadryl. Then guaifenesin. I was having tachycardias every few days, but no farther apart than 20 days, max, and this went on for years. And I constantly had to fear taking any new medication because it might trigger my arrhythmias. So, anyway, I had my serum magnesium checked frequently while taking magnesium oxide (readily available in neighborhood pharmacies) as a supplement, and while also enduring the awful things this laxative was doing to my guts. But the tachycardias got less frequent and less severe. No more emergency room visits. I started looking for magnesium salts that would be less gut-disruptive, and I tried magnesium bisglycinate. It helped some, but an article from a German pediatric nephrology journal recommended magnesium chloride to minimize side effects. BTW, my hypomagnesemia appears to be a genetic defect causing insufficient resorption of magnesium in my thick ascending limb of the loop of Henle. The article also indicated that the only treatment for this problem is oral or i.v. MG supplementation. So I ordered Double Wood Supplements' magnesium chloride and started replacing the magnesium oxide with that. I also was able to reduce the total Mg intake because of the better absorption of the chloride than the oxide. And now? Today is November 19, 2019. My last tachycardia was May 4, 2019. All is quiet on the cardiac front! And I spend much less time in the bathroom. Go, Double Wood! And thanks. Regarding their product, I find it easy to take (moderate sized-capsules) and have nothing negative to say about it at all. I am extremely pleased with it and intend to get rid of the one remaining oxide pill I am still taking (good idea to change things slowly if possible). During this process I am continuing to monitor my serum magnesium levels. BTW, I had to take about 5 times the maximum recommended Mg dosage (I was taking about 1600 mg/day) to get my serum Mg levels to mid-normal (about 2.0 mg/dl, or whatever the measurement units are). Also, all of this is with the full knowledge and approval of my GP and an endocrinologist I saw for my hypomagnesemia problem. Neither of them found anything else wrong, but biological fluid tests clearly show renal magnesium wasting--almost certainly genetic. One more comment--anyone with mysterious tachycardias for which nobody can find a cause? Check your serum magnesium. For good reason, it is sometimes called "the forgotten cation" and is critical for proper functioning of innumerable human biological processes. ---Stan Zison, Ph.D. Read more
