After doing some studying of books I am led to the conclusion that supplementation is a bit of a snake oil industry. The symptoms that I saw listed as being indicative of Mg deficiency are also listed as being the results of Mg toxicity. They are also listed in a huge amount of other illnesses. hmmmmmm
As Dorothy reminded me, I wrote this before I read the real story on 'snake oil'. I should have known.
Turns out that there really was/is snake oil and it really is effective, From Nenah Sylver's book "The Rife Handbook" page 56 is the following explanation. This is yet another example of the early allopathic drug companies trashing things they knew nothing about, or essentially trashing the competition. Similar to what they do nowadays with Quackwatch...
"Snake oil originally came from China, where it was used to alleviate inflammation and pain in rheumatoid arthritis, bursitis and similar conditions. Chinese labourers, on section gangs doing the grunt work involved in building the railroad tracks to link North America coast to coast gave it to Europeans with joint pain (bursitis and arthritis). When rubbed on the skin above the pain, snake oil brought relief, so the story goes. Patent medicine men ridiculed the claim. [Hence, today people refer to the remedy that doesn't work as "snake oil".]
In 1989, a nutrition-oriented medical doctor from California decided to find out what snake oil contains. He obtained a sample of the oil from San Francisco's Chinatown, had it analyzed, and found that [out of the 1/4 that is not carrier oil]... 25% of the product is oil from Chinese water snakes, which contains 20% of the important Omega 3 derivative eicosapentaenoic acid (EPA) as well as 48% myristic acid, 10% stearic acid (18:0), 14% oleic acid, and 7% linoleic plus arachidonic acids. At 20% EPA, Chinese water snake is the richest known natural source of the parent of the series 3 prostaglandins, which inhibit the production of pro-inflammatory series 2 prostaglandins. Like Essential Fatty Acids and their other derivatives, EPA can be absorbed through our skin. Salmon oil, the next best source of EPA, contains a maximum of only 18% EPA. Other fish oils contain less.
The bottom line is that the traditional snake oil is natural and therapeutic. The snake oil salesman is vindicated." Nehnah Sylver PHD / The Rife Handbook
