The way to research Mag supplementation is by what the Mg is bound to at the molecular level.
Mg is very very reactive so it doesn't exist in its pure form. It blows up when it gets near water. That would be bad.
Mg is usually bound to oxygen. This is called Magnesium oxide. It's very cheap to make, and very very stable. it's too stable, and difficult to break down even in stomach acid, so you end up only using about 5 or 10% of what it's ingested from what I've read.
There's also Mg bound to calcium, and Mg bound to Chlorine. These get a little better in absorption.
Then there is Mg bound to amino acids like Malate, glycinate, and taurate.
The best I've found that works for me is Magnesium Glycinate. I buy it on amazon. There are plenty to choose from. I like Kal.
so to summarize there are three way to supplement Mg
1. Mag Ox
2. Mag salts, this is bonded with chlorine, or sulfur (mag citrate, slo mag, epsom salts which are mg sulfide). These are medium absorption.
3. Mag bound to amino acids (best absorption, may give you diarrhea though)
Thank you so much . I'm gonna discuss it first with my cardiologist, and I will let you know all that happens ;)..I have irregular beats horribly.:(
Hello Kelle, I was just recommended a magnesium supplement by the brand name of Calm. They sell a powdered bottle, or you can buy single use packages, I bought a few single serves and tried it once so far. Coincidentally (maybe), my PVCs were not as bad as usual. Granted, from what I see from this site, people have them way more frequently that me, so I don't know if it's a sort of placebo effect or not, but at this point I am willing to try anything. Good luck with all the testing, I'd be curious to know how it works for you.
