Do you have a magnesium deficiency? You might. It’s not as uncommon as it might seem. In fact, approximately half of all Americans aren’t getting sufficient amounts of magnesium in their diets.1 Surprising, isn’t it?

You see, magnesium doesn’t get talked about nearly enough — it tends to live in the shadow of more famous minerals, like iron and calcium. But it’s time to shine a little light on it.

This mineral is absolutely essential to the health of multiple body functions. And not getting enough of it can lead to a magnesium deficiency and the potential for more serious health consequences.

So, if you’re curious about this mineral’s effect on your body — and what happens when you don’t get enough of it — read on.

A Mighty Mineral

Magnesium is a necessary component of approximately 300 biochemical reactions in your body that keep you running efficiently. Among them:

  1. Low Magnesium Symptoms | Gundry MDRegulating muscle and nerve function
  2. Helping keep blood sugar levels stable
  3. Helping develop strong bones
  4. Energy production
  5. Transporting calcium and potassium across cell membranes2

Over time, a magnesium deficiency can be detrimental to the health of your bones and heart. It may also lead to unstable blood sugar levels.3

To prevent the development of any unnecessary health problems, it’s important to make sure your body has adequate magnesium levels.

Low Magnesium Symptoms

Unfortunately, determining whether or not you’re magnesium deficient can be a bit tricky. Blood tests are often used to assess low magnesium symptoms, but the scientific community generally agrees that they aren’t the most reliable indicator. Part of this is due to the fact that only 1 percent of your body’s magnesium is stored in the blood.4

So, how can you tell if you have a magnesium deficiency? You can start by doing a little of your own detective work. Here are some of the most common low magnesium symptoms:

  • Low mood5
  • Irritability and confusion6
  • Frequent migraines7
  • Loss of appetite
  • Nausea
  • Weakness
  • Numbness and tingling
  • Muscle pain and cramping
  • Irregular heartbeat8

As always, it’s a good idea to check in with your doctor if you have significant health concerns. They’ll be able to take a full inventory of your health, ensuring you’re getting any medical attention you might need.

Magnesium To The Rescue

Research has shown that increasing your magnesium intake can do a lot to improve your health and well-being. Science supports the idea that this mineral …

    • Helps reduce migraine symptoms: A 2015 study found that migraine patients who increased their magnesium intake saw a decrease in symptom severity and experienced fewer migraine episodes.9
    • Helps manage stress: Evidence shows that magnesium may be effective in helping alleviate feelings of emotional stress.10
    • Supports digestive regularity: Magnesium can help ensure the digestive system works smoothly and efficiently. It may also help relieve uncomfortable digestive symptoms.11
    • Helps maintain healthy blood sugar levels: A higher intake of magnesium is associated with more stable blood sugar levels.12

Building Up Your Magnesium Levels

So, how can you build up your body’s stores of magnesium and improve those low magnesium symptoms? Well, the best place to start is your diet.

Now, you might be wondering just how much magnesium you should be getting each day.

According to the National Institutes of Health, adult men should aim for 400-420 mg of magnesium, while adult women should be getting 310-320 mg.13 And with healthy, intentional eating, it’s entirely possible to get these recommended amounts of magnesium.
