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!

Essential for my perimenopause season

Mag-Key has really helped! Afternoon fatigue, mood swings, and restlessness at night was really draining me until I started adding some vital supplements to my daily regimen. I really believe the magnesium and vitamin D has been a game changer for me!

Mag Key Rocks

My cardiologist recommended that I increase my intake of magnesium to help me with my A-Fib. He specifically told me to order MagKey because it had the most effective formula of 4 different kinds of Magnesium. I started taking it 10 years ago and the number of A-Fib events has decreased each year until I now only have a few one day A-Fib events each year. Not to mention that I sleep better, and my gut health has also improved. I plan on using mag key for the rest of my life!

My daughter uses this and suggested it for my husband, who has Parkinson’s. He wasn’t able to sleep at night and I’ve tried so many brands of Magnesium. This is the only thing that helps and thank goodness he can now sleep all night and the magnesium is good For him. So thankful for it.

Magnesium Mag/Key

Mackey helps with my insomnia. I’ve tried just magnesium glycinate by itself but these extra types of magnesium seem to be a bonus! Excellent product!

Best one on the market!

I have used this magnesium off and on for about 25 years. I have tried at least a dozen other brands through the years. None of the others come close to what Unikey's magnesium does. Helps me sleep well, helps keep my bowels regular, and keeps nighttime leg cramps at bay. And I feel assured that it is helping our hearts too!
