The 5 Best Magnesium Supplements of 2025

What is magnesium and what types are there?

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 a 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.
