MrsD (and anyone who knows) -

I have a real puzzler. Over the past year of so I have encountered on three or four occasions a very unsettling reaction to magnesium supplements and decided to take the bull by the horns this morning but I need help with understanding my observations.

This morning was typical to the other times. I awoke at 4:00 AM and fully on by 6:00 AM. Sinemet, beta blocker, ACE inhibitor, multivitamin, extra Bs, ginger, and psyillium. Added a single capsule of magnesium citrate (165 mg). Suggested daily dose per label is three such capsules. Finally, added potassium gluconate to keep the Mg company.

Within minutes I felt a sense of extreme fatigue washing over me so quickly that I almost had to "rush" back to my bed lest I fall to the floor! And the part that has me really concerned is that about an hour into this I experienced some mild respiratory distress! Just enough to prompt me to focus consciously on my breathing while making me glad that I had reduced the dosage.

Finally, after about two hours, the effect? reaction? resolved over about a ten minute period.

Somewhere in that initial period I managed to get my BP. It was 160/106 with a pulse of 62. All fairly typical for me under the circumstances.

I have searched widely for info but there is little on acute negative experience with magnesium. It seems to be universally praised except for a little material on LiveStrong! about possibilities for overdose when using supplements - including respiratory distress. But other than the test sample none is involved here.

If you could share your thoughts I would greatly appreciate it.
