I've had two emg by local neuro, emg by Northwestern neuro, mri of spine, mri of brain, ck blood test...all came back clean. I was at the end of my rope and everyone was thinking I was a quack. I went back to my nurse practitioner and told her I wanted to start from the beginning and get a regular blood test and liver, thyroid and diabetes test. Well....guess blood test came back with very low levels of magnesium. You think the neuro's would have suggested that. Im now on magnesium pills and feeling very much better. I still have some twitches but not as many as before and very little cramping. Im feeling good again. I did however get conflicting reports as to if I should be taking Magnesium Chloride, or Magnesium Oxide. NP says Magnesium Chloride and Pharmacist says Magnesium Oxide. Any thoughts or opinions?

I'm not sure exactly which one is required I'm just sooo happy that you're feeling better.

Magnesium oxide is better absorbed. Usual dose is 400mg twice daily.

Figures you'd know that Joe. Good thing we have someone like you to advise us! I have a question about that though....should everyone who is twitching have their Magnesium levels checked? How about Potassium?

I think my neuro only checked my B12 levels...along with other types of tests like ANA, thyroid, RA factor...but I don't remember getting that one done.

:D, Jen

Joe.....take a look at this....

Hi kdog,
The problem with any oral magnesium supplement is its tolerability. They are all rather poorly absorbed and can cause diarrhea and GI upset. You probably won't have much "net" absorption of anything if your on the toilet all day. Slow Mag (Magnesium chloride) is enteric coated precisely because it is more harsh on the GI tract than magnesium oxide. Magnesium chloride is generally given IV not orally. I'm not saying you can't use Mg Chloride as long as you can tolerate it but Mg Oxide tends to be more tolerable.
The bigger question is why is your magnesium low to begin with? It is somewhat unusual for a person to have low magnesium and the cause should be sought. I would have your physician try to determine the cause.

In answer to Jenn311 regarding checking serum electrolytes, that would typically be one of the first things your primary care doctor would do even before sending you to a neurologist. I would be suprised if that hadn't already been done.

I'm sure magnesium helps. I started with a Ca-Mg combo and that did nothing but now I take straight Mg 250 mg and I swear my twitching is improving (except my stupid right foot :roll: ).
