Q. I used to take verapamil for occasional supraventricular tachycardia. Four years ago I switched to magnesium, alternating 250 mg one day, 500 mg the next.
No more irregular heart rhythm. In addition, I sleep better and have no more constipation. Since I have no prescription insurance, I have saved myself a lot of money!
A. A study that provided women with less than half the RDA for magnesium (which is 320 mg/day) found that while on the reduced regimen they had significantly more supraventricular beats (American Journal of Clinical Nutrition, March 2002). Magnesium also is known to be effective against constipation.
