Hi,

I recently got a muscle twitch in one of my muscle that just started one day and kept happening every day quite often. I started taking magnesium and within a few days it stopped. So I though I must have had low magnesium.

However, a blood test revealed I had high magnesium?

The blood test also revealed normal potassium, normal calcium, normal iron, normal/high b12 (right at the top of the reference range) and low zinc.

Is it possible that although my blood has high magnesium, there wasnt much in my muscles?

The only other thing I can think is that a few days before my blood test I started taking 1000mg magnesium (with calcium) and 200mcg b12 tablets. Could these few days of supplement taking affect the blood results?

Thanks
Jonny
