The Best Magnesium Supplements

Magnesium supplements are a great way to increase your daily magnesium levels if you have trouble getting the recommended amount of magnesium through your food. Magnesium is a crucial mineral that keeps your body healthy by supporting the body’s nerve and muscle functions as well as its energy production. It can also help prevent high blood pressure, keep your bones strong and your heart steady. You can meet your daily recommended levels by eating foods rich with magnesium like dark chocolate, leafy greens, nuts or even whole grains.

While making sure you get the right amount of magnesium is important to keeping your body healthy, adding large doses of magnesium supplements to your diet can do more damage to your body than good. Too much magnesium can cause diarrhea, nausea, cramps, muscle weakness, and interact with certain medications like antibiotics. It could even be fatal. Before you run to the store or impulse buy a bottle online, it's important that you talk to a health care provider before taking any medication to understand what your body really needs.

That said, there's a wide variety of magnesium supplements on the market that work to combat different issues in the body. For example, magnesium citrate is one of the most popular and inexpensive forms of magnesium supplements and is easily absorbed into the body. Its combination with citric acid also works as a mild laxative and helps with constipation. If you don’t need help in that department and want to avoid constantly running to the bathroom, this type of supplement might not be for you.

If you're someone who has a slow metabolism as well as low magnesium levels, a magnesium chloride supplement might be a better fit. Like mentioned above, it's vital that you speak to your doctor or a medical professional before buying supplements so you can fully understand what products are right for your body's needs. If you’ve already done that, great — keep scrolling to see some of our top magnesium supplements.
