Nocturnal Leg Cramping; Restless Leg Syndrome; Magnesium Deficiency


My wife deals with nighttime leg cramps. We have tried a couple of things that seem to work, but what do you suggest?


Nocturnal leg cramping is not the same thing as restless legs syndrome, which is what most people think it is. It is actually caused by a magnesium deficiency, and Magnesium deficiency is the most common micronutrient deficiency in our population.

The way that you can correct this, is by taking something very inexpensive. It is called chelated magnesium. These are organic magnesium salts. The only one you don’t want to get is magnesium citrate, because magnesium citrate is going to have a laxative effect, and will not fix the leg issue.

Magnesium gluconate, glycinate, malate, or taurate, are the salts that will alleviate leg craps. The dosage is 200 to 300 milligrams at bedtime. After a week, increase the dosage by 50%. And If you have to, you go up by another 50%. So somewhere between 200 and 400 milligrams of chelated magnesium, things should settle down.

There are going to be people out there saying, “She should take potassium.” This is nonsense. Potassium depletion is very, very rare unless you’re taking loop diuretics, with dehydration.

Magnesium deficiency is the most probably culprit. Magnesium replacement will fix her problem.
