Magnesium is having a moment. There are countless videos on social media highlighting the important role magnesium plays in our overall well-being. But despite magnesium’s importance, an estimated 75% of US adults aren’t getting enough of it in their diets. Not only does it support energy production and aid in muscle and nerve health, but it may help stave off insomnia. Are you getting enough daily magnesium?

Before you buy a magnesium supplement or any dietary supplement, talk to your doctor to make sure you need it. Too much magnesium from food sources isn’t a concern for the average adult, but the same isn’t true for supplements. If you take in too much magnesium from supplements, it can cause nausea, diarrhea and abdominal pain.

Here’s what you need to know about finding the best magnesium supplement.

What is magnesium?

Magnesium is one of the most abundant minerals in the human body — it plays a vital role in various bodily processes such as muscle movements and brain function. Studies reveal magnesium may improve depression symptoms, sleep, heart health and blood sugar levels.

There are many types of magnesium, which include magnesium aspartate, magnesium carbonate, magnesium chloride, magnesium citrate, magnesium gluconate, magnesium hydroxide, magnesium lactate, magnesium oxide and magnesium phosphate. The form of magnesium is determined by what it is bound with (for example, magnesium citrate is magnesium bound with citric acid), and some forms are more easily absorbed by the body than others.

Magnesium is found naturally in foods such as:

Seeds
Nuts
Greens
Soy milk
Beans
Whole grains

If your diet lacks many of these foods, you may need added magnesium. If you already take a multivitamin with magnesium, you don’t need an extra supplement. Consult your doctor before adding magnesium supplements to your diet.

We reviewed a number of magnesium supplements, along with their prices, brands, ingredients and consumer reviews. Here are our picks for the best magnesium supplements.

Dosage: 1 tablet, daily with a meal
Form of magnesium: Magnesium oxide

Nature’s Bounty is another well-known and accessible brand. Sold in Target, Walmart, Walgreens and CVS, Nature’s Bounty has been producing quality vitamins for over 50 years. Its products, including its magnesium supplement, contain no artificial color, flavor, sweeteners, sugar, starch, soy, gluten, wheat, yeast or fish. The supplements contain 500 mg of magnesium oxide, which is about 119% of the daily recommended value. They also contain vegetable cellulose, dicalcium phosphate, calcium carbonate, citric acid, medium chain triglycerides, polydextrose and vegetable magnesium stearate.

The other ingredients include hypromellose (cellulose capsule), rice flour, silicon dioxide and stearic acid (vegetable source).

Liquid magnesium is also a great option for those who dislike swallowing pills. Trace Minerals’ liquid magnesium comes with a measured dropper, making it easy to know how much magnesium you are getting. However, it is recommended that you don’t take all 4 milliliters in one sitting. It’s best to distribute the serving size throughout the day. One daily dose of this liquid is 400 milligrams of magnesium chloride — 100% of the daily recommended value. In addition to magnesium, the bottle also contains potassium, sulfate and boron. All of the ingredients are natural, non-GMO and gluten-free and made without artificial flavors, sweeteners and any known allergens.

Pros

Alternative to swallowing pills

However, you shouldn’t take a magnesium supplement daily if you’re already obtaining your daily amount in your diet. Speak with your doctor before adding any supplements to your diet.
