I also would like documentation about
That doctor's statement.

Doctors are known for making weird
And sometimes inaccurate or stupid
Statements to frighten patients.

In fact LOW magnesium levels are common
And can lead to torsades de pointes... A fatal
Arrhythmia.

SlowMag in fact was formulated for doctors
To use for their patients. It has remained OTC in
fact.

Using the RDA dosing is all one needs..
High doses are not necessary for most people.
But studies show that up to70% of people
in the USA do not get the RDA for magnesium.

my mag levels are in the lower range of "normal"
 

so i believed that using morton's would 1) help with foot & calf pain (which it does) and 2) have a positive effect on blood glucose & blood pressure (don't have any evidence of that yet..my BP is fine...one area which has mercifully been unaffected by the general deterioration of my health) and 3) raise my mag levels (which will be tested on my next round of bloodwork)

i hope that lewie's doc is mistaken!

and mrs d, thanks for the info on low mag + torsades de pointes...scary! will ask the cardio to clarify mag levels on my next visit.

In general the mid range of magnesium is
Not representative of tissue levels.
The very low range and very very high
Are used diagnostically for serious often
emergency situations.

Daily use of diuretics and chemotherapy
Can put one into a serious low area that can
impact the heart. Very high levels can be
Found in people abusing Fleet enemas and
Fleet laxatives but the latter were changed
For testing preps because of this.

Doctors use very high levels in treatment infusions
IV and those can be problematic
For patients with kidney problems.
Oral use usually causes diarrhea as a warning
To lower dosing but no such warning comes
With IV admin where doses may approach
6 grams IV.

My husband has been getting these IV's about every 3-4 weeks for treatment of myasthenia gravis, and always has a headache afterwards that sometimes lasts 2-3 days. Would this be the reason for the headaches?

IVs for MG may be IVIG... And those often
may have headache as a side effect.

Are you positive his IV is mag sulfate?

A lot depends on the IV dose of mag.
1 gram is not as problematic as higher
Doses. Also the infusion rate should be
Slow for mag IV.

Report that side effect to the doctor.

I have never heard of IV mag for MG.

In fact there are papers about IV mag causing
MG to manifest in patients.

Thank you, MrsD. My mistake--it's IVIG that he's getting. The doctor gave him a prescription, but his writing is so bad, even the nurses have troble reading it and have to call him, so we're not sure exactly what all is in it. They don't mix it til he gets there. He's going to tell them at the hospital about the headache though and also the doctor.

extra additives or fillers.
 

This is very interesting as I have never heard of magnesium irritating the heart lining, You always thought well magnesium helps muscles and it can also help the heart. But never did I think it would actually do something to the lining. I do however tend to think that many supplements/vitamins that are not well purified and have extra dusty fillers in them(i'm thinking of a few NOW foods ones) These ones in particular seem to cause allergic reactions to me in particular, which is why I stay away from them. Most of the thorne research ones are fine with me, just certain ones I know aren't of good quality.
