No particular ailment, but I have been interested in Magnesium supplementation ever since I had a couple of "racing heart" episodes several years back, and discovered that I could calm things down by taking Epsom Salts (Magnesium Sulfate) in water... awful taste and also a powerful laxative. I began to wonder how I could get the same effect in a more palatable way, without the laxative effect. Eventually I found the"Magnesium" webpage and learned the following:
How to make your own Magnesium water [like the 'Noah' water being sold by a certain company, which bottles water from a spring that is naturally rich in bicarbonates of Magnesium].
The assumption is that we could all use more magnesium in our diet, which may help reduce blood pressure, reduce the likelihood of kidney stones, etc.
Here's how to make your own Mg-rich drinking water:
Buy a bottle of Carbonated Seltzer water - NO SODIUM, just carbonated "fizz" water, unflavored. Refrigerate for a couple of hours.
Get another, larger bottle, and pour 2/3 of a capful of PLAIN (no-flavor) Philips Milk of Magnesia (which is Magnesium Oxide, an alkaline laxative) into the large bottle. (The bottle comes with a plastic measuring cup which is what I mean when I say 2/3 capful.)
Now quickly open the bottle of carbonated water (water carbonic acid) and empty it into the large bottle containing the 2/3 capful of Magnesia.
You will have a bottle of milky/cloudy liquid which is in the process of neutralization between the carbonic acid and the magnesium oxide-- leaving a neutral salt, Magnesium Bicarbonate.
Let the cloudy mixture sit for a while at room temperature, until the liquid clears; there will be some white precipitate at the bottom. Shake again and let sit again. When clear, refrigerate. THIS IS YOUR MAGNESIUM BICARBONATE CONCENTRATE. Unlike the chalky taste of straight Milk of Magnesia, or the biting-fizzy taste of seltzer water, your concentrate will have a strong, sweet, slightly "soapy" taste. You will be DILUTING it in water for drinking purposes.
When it has chilled, pour a small amount into an empty 1 liter bottle (approx. 1/2" of concentrate at the bottom) and fill the rest of the bottle with pure drinking water.
You have now created a sweet-tasting, Magnesium-enriched drinking water, and you're also getting your Bi-carbs without all the Sodium you'd be getting from Baking Soda.
I have been making and drinking this Mg water since Nov. 2006 (I write this in July of 2007) and have not had any bad effects from it. I take a bottle to work and sip it during the day. My resting heart rate seems to have gone down and I feel more relaxed in general. I can't say it has greatly improved my high blood pressure, but it has helped some, and I know I am getting enough Magnesium. Probably would be beneficial to supplement with Calcium for balance.
Try it and see what it does for you.
