Kidney stones and Magnesium

If there is too much calcium in the kidneys and not enough magnesium to dissolve it, you can get kidney stones. – Dr Mark Sircus’

"A 38-year-old man had a 10-year history of weekly kidney stones. Magnesium therapy stopped this for 12 months, at the end of which the patient decided on his own to discontinue treatment. Calculi recurred within two weeks, and Dr. Sauberlich observed that he gladly resumed therapy, also on his own. He has been asymptomatic again for three months.

In another medical article, we now find that kidney stones come usually where there is a deficiency of magnesium.

Let us look into the second-mentioned article which appeared in Nutrition Reviews (October, 1961). It says that as far back as 1931 it was known that kidney stones could result if there were a deficiency of magnesium.

In The Lancet (2, 174, 1932), W. Cramer found kidney stones in rats that were on a low magnesium diet. These rats were normal except for the kidneys.

Magnesium, the vital mineral in this partnership that is proving so effective in preventing the formation of kidney stones, is indispensable for a proper regulation of calcium metabolism. When animals deficient in vitamin B6 were given high levels of magnesium, they continued to show oxalic acid in the urine but they no longer converted this acid into kidney stones.

Magnesium, then, by improving the body's utilization of calcium, has the effect of a solvent-preventing the caking and crusting, like lime in your teakettle, of unassimilated calcium.

One study of 241 male kidney stone patients found that they all had a few things in common. They all had very low amounts of magnesium in their diet and they all ate large meals consisting of animal protein at dinnertime and late in the evening.

Magnesium is reknowned for its calcium channel blocking effect and has been shown to reduce the formation of stones by reducing the calcium oxalate in the blood that makes up the stones.

In Japan researchers found that in certain basalt rich areas of the country where the magnesium to calcium ratio was very high the incidence of kidney stones was almost non-existent. In limestone rich areas where the magnesium to calcium ratio was very low, residents had a high incidence of kidney stones.

149 recurrent stone patients were given magnesium and B6 daily for 4.5-6 years. Before receiving this treatment these patients suffered an average of 1.3 stones per person per year. Stone formations fell to .1 per person per year, a 92.3% improvement!

Magnesium deficiency has not yet been convincingly demonstrated in man. However, urinary magnesium concentrations are abnormally low in relation to urinary calcium concentrations in more than 25% of patients with kidney stones. A supplementary magnesium intake corrects this abnormality and prevents the recurrence of stones. Magnesium seems to be as effective against stone formation as diuretics.
