7 Signs You Are Magnesium Deficient

(And how to fix it…)

Did you know a staggering 80 percent of American adults are magnesium deficient?

And considering how magnesium is responsible for over 300 biochemical reactions in your body, affecting bone health, immune function, metabolism and more, that’s a problem.

You might be magnesium deficient if:

  1. You experience muscle cramps and spasms…
  2. You feel stressed, tense, or anxious…
  3. You suffer from headaches or migraines…
  4. You have low energy…
  5. You have trouble falling asleep or staying asleep…
  6. You have high blood pressure…
  7. You have weak or brittle bones…

These are some of the most common signs of magnesium deficiency.

And if you recognize yourself on that list, you may be one of the millions of Americans not getting enough of this magnificent mineral.

Why Is Magnesium Deficiency So Widespread?

Good question, and there are several reasons:

  • Industrial farming depletes soil of minerals which means plants (and animals fed from those plants) are lower in magnesium.
  • Fluoride and chlorine, which are added to our water supply, bind to magnesium, making our water low in this mineral, too.
  • Consuming too much sugar and caffeine deplete your magnesium levels.
  • Stress can also drain your body of magnesium.

Fortunately, you can take action to boost your magnesium levels — and that can have a big impact on your health!

In my experience, the right combination of magnesium-rich foods and a high-quality magnesium supplement is ideal for boosting low levels.

Some of my favorite magnesium-rich foods include:

  • Organic dark chocolate
  • Nuts and seeds (especially pumpkin seeds)
  • Avocados
  • Leafy greens like kale, spinach, and Swiss chard
  • Wild-caught fish
  • Sprouts
  • Grass-fed beef

What about magnesium supplements?

There’s a dizzying number of magnesium supplements available online and in stores. But the only one I use and recommend to family, friends, and clients is Mag-Key.

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:

Magnesium Taurinate

Supports healthy heart function.

Magnesium Malate

Helps soothe sore muscles, cramps, and headaches.

Magnesium Glycinate

Can help ease stress and anxiety, irritability, and insomnia while improving mental calmness, relaxation, and concentration at the same time.

Magnesium Orotate

Helps boost energy and endurance, and also protects your heart, nerves, and tissue.

Thanks to this blend of four powerful forms of magnesium, Mag-Key is able to support a wide range of health benefits — all from a single easy-to-take supplement.

Listen: magnesium is, hands down, one of the most important minerals for your health. Maybe the most important.

That’s because…

You Need Magnesium for 350+ Of Your Body’s Critical Functions!

You need magnesium for:

Energy creation: magnesium helps convert food into energy.

Stress relief: magnesium is the “relaxation mineral” that helps ease emotional and physical tension.

Strong bones: together with calcium, magnesium is necessary for strong, flexible bones, especially as we get older.

Proper digestion: magnesium alleviates constipation and promotes regularity (essential for both detox and maintaining a healthy weight!)

Headache relief: magnesium can relieve headaches and studies show it can even help prevent migraines.

Restful sleep: magnesium helps maintain healthy levels of GABA, a neurotransmitter that promotes deep, restorative sleep.

Talk about a multitasking mineral!

Sadly, 8 out of 10 Americans don’t get enough magnesium, which means far too many good people are missing out on the health they deserve.

But that doesn’t have to be you.

    But please bear in mind:

    Because we make Mag-Key in small batches, and rigorously third-party test it for purity, it’s often difficult to keep up with demand. In fact, we’ve sold out a couple times already this year.

    I’m grateful we currently have Mag-Key in stock. But, I don’t know when we’ll sell out again. (So thank you in advance for understanding.)
