portrait of Ann Louise Gittleman

I’m a big believer that everyone should supplement with high-quality magnesium. And for good reason.

A recent study from the National Institutes of Health suggests nearly 8 in 10 Americans don’t get enough magnesium.

And because your body requires magnesium for over 300 processes -- everything from your heartbeat to your metabolism -- low magnesium can cause all sorts of problems. And that's where supplementation can make a big difference.

Of the many, many magnesium supplements on the market, Mag-Key gets my vote because it’s the only one I’ve seen that includes four UNIQUE forms of magnesium - malate, orotate, glycinate and taurinate!
