tkr1, I have a lot of pvs & palpitations. My Cardilogist recommended me to take this daily to help both. I can tell a difference. I do feel more relaxed in my muscles (Fibromyalgia) taking it. It is also good for constipation, leg cramps & migraines. There is a product called Calm Natural Vitality Powder that a lot of folks take at night for sleep and it has magnesium in it. Please consult with your doctor before trying these.

You have to be careful with the dosage as to much can give you diarrhea. I do well with 200 mg of the magnesium glycinate. Some folks are able to tolerate more...not me.

Blessings & Prayers....
