I purchased this product for the $1.41 Cleanse (along with Azomite, Castor Oil, Milk Thistle, Pysllium Husk & Lemon Juice) and the cleanse really works!!!!

My doctor suggested I take magnesium for my migraines so I gave it a try but had to stop because it upset my stomach. When I told her about my stomach problems she suggested taking magnesium oxide rather than plain magnesium to avoid the digestive problems. I've been taking these close to six months and haven't had any issues with my stomach. So glad I switched!

Magnesium oxide is a great form of magnesium It’s true that magnesium oxide is not as easy to render soluble as some other magnesium salts. It’s therefore not absorbed as rapidly as other forms of magnesium, e.g. magnesium citrate, gluconate, lactate, aspartate.<br /><br />But although magnesium oxide has a lower rate of absorption it contains a MUCH greater amount of actual magnesium to begin with. More than what is provided by other magnesium salts.<br /><br />Therefore, even with the lower rate of absorption, magnesium oxide still delivers more magnesium per tablet. So more magnesium gets into your bloodstream to deliver all its many benefits to your bones and body!<br /><br />This is illustrated in the table Comparison of Magnesium Salts below: 1-2<br /><br />Comparison of Magnesium Salts<br />MG Salt % Elemental MG % Elemental MG Absorbed Mg’s of Elemental MG Absorbed per 100 mg of MG Salt<br />Oxide 60% 23%* 13.8<br />Carbonate 28% ~20% ** ~5.2<br />Chloride 26% 20% 5.2<br />L-lactate 12% 42% 5<br />Citrate 11% 30% 3.3<br />Aspartate 8% 42% 3.3<br />Glycinate 14% 23% 3.2<br />Gluconate 6% 19% 1.14<br />*On the web, you’ll see many sites claiming that only 4% of the magnesium in magnesium oxide is absorbed. This claim is based upon a small study by Firoz et al. (2001), which is discussed fully below. The actual data in this study shows something very different. The stated percentage of elemental magnesium absorbed from magnesium oxide in the above table — 23% — is the statistic provided in a review and meta-analysis of numerous studies by Ranade et al., (2001), cited below.<br /><br />**Magnesium carbonate is nearly insoluble, but in the presence of stomach acid (HCl), magnesium carbonate is converted into magnesium chloride, which allows 20% of elemental magnesium to be absorbed.<br /><br />As you can see, magnesium oxide contains the most elemental magnesium of 60%. And 23% of this can be absorbed.<br /><br />Magnesium citrate, for example, contains only 11% elemental magnesium. And only 30% of this is absorbed.<br /><br />So the percentage of elemental magnesium to begin with is just as important as the rate of absorption.<br /><br />BUT SHAME ON YOU DOUGLAS LABS - you’re supposed to be a top notch product but you put titanium dioxide in these pills which is a know carcinogen to humans.,.. I had to switch to now foods oxide powder -pure mag oxide nothing more.

I switched to Magnesium Oxide 500 mg daily, from Magnesium Taurate 200mg, on the advice of my headache doctor. My migraines are nearly gone, and the doctor thinks the magnesium oxide deserves the credit. I'm also take vitamin B2 400 mg, carefully watching my triggers (headlights, sunlight, fluorescent lights, flashing lights), and getting physical therapy on my neck. Still .... I've doing all that other stuff for 6 months, but the migraines didn't abate until I switched to this type of magnesium.

My Doctor has me taking extra magnesium oxide, like four 500 mg per day and I found these mag oxide from Douglas Labs to be great. Douglas Labs shipped my orders (second time) the day after I placed the order with Amazon.com. It looks like I will be taking this mag oxide for a long time and I will continue to order from this great supplier.

Mag oxide & B6 taken together dissolve & prevent kidney stones, & also increase urine output & pressure. I love it! ;-) I have to take this combo a few times a year. I take about 400 mg. mag oxide w/ 10-50 mg. of B6/ day. Google it, there's much more info to back it up! :-) I first heard about it over a decade ago by Dr. Clark/ curezone.
