The Best Magnesium Supplements

It’s important to consume enough vitamins and minerals, so if you think you’re not getting ample magnesium in your diet, add a magnesium supplement. Magnesium is abundant in the human body and plays a role in more than 300 internal processes, including synthesizing DNA and RNA, maintaining healthy nerve functions, and supporting bone health. Magnesium supplements may also help with a range of complaints, such as insomnia and headaches.

We reviewed dozens of magnesium supplements to identify the best of the best, considering a range of factors such as delivery method (sprays and powders versus tablets and capsules), form of magnesium, dosage, and customer ratings.

Best Magnesium Supplement Overall: Nobi Nutrition Magnesium Complex Premium

Nobi Nutrition Magnesium Complex Premium is our most highly recommended magnesium supplement. It’s a magnesium complex containing two distinct types of magnesium: magnesium citrate which has an incredible 90% bioavailability so it’s highly absorbable and magnesium oxide which is less bioavailable but contains the highest amount of elemental magnesium by weight of all the different magnesium types.

In each bottle, you get 60 easy-to-swallow 500 mg capsules. These are vegan capsules, so they’re suitable for anyone who avoids consuming gelatin for ethical or religious reasons. Retailing at roughly $22 for 60 capsules, they are on the pricey side, but they have a high Amazon rating from a large number of reviews, and buyers praise them for all kinds of helpful properties from relieving insomnia and leg cramps to lessening the symptoms of menopause.

Nobi Nutrition Magnesium Complex Premium Key Features: 

  • Made in the USA in an FDA-approved facility
  • Tested for quality by a third party
  • Vegan-friendly formula

Best Magnesium Supplement Tablets: Nature’s Bounty Magnesium

Best Magnesium Supplement Tablets

Nature’s Bounty Magnesium

Containing 200 tablets, this bottle will keep you in magnesium for some time.

If you prefer tablets over capsules, or you’re simply looking for a lower priced option, consider Nature’s Bounty Magnesium. This supplement contains magnesium oxide only, which isn’t as bioavailable as some other forms of magnesium, which means you may need to take a higher dose to get the same effects. However, since this bottle contains 200 tablets of 500 mg for around $10, it won’t put you out of pocket.

The tablets are vegetarian, and free from all common allergens, including gluten, soy, milk, eggs, and shellfish. They’re laboratory tested for safety and quality and free from GMO ingredients.

Nature’s Bounty Magnesium Key Features: 

  • Coated tablets for easier swallowing
  • Made in the USA
  • 500 mg per tablet

Best Budget Magnesium Supplement: Nature Made Magnesium Oxide Tablets

Best Budget Magnesium Supplement

Nature Made Magnesium Oxide Tablets

Basic magnesium tablets at an extremely low price.

Sometimes, getting the cheapest option available is essential and you won’t find a much lower price than these Nature Made Magnesium Oxide Tablets, which cost just $4.20. You do only get 100 tablets to a bottle and each tablet contains 250 mg of magnesium, so this might not be the best value option out there, but if pure low price is your goal then buy, buy, buy!

Like our top magnesium tablets, these contain just magnesium oxide, which hasn’t got the best bioavailability. The stated dosage is just one 250 mg tablet per day, but you may wish to take two if you really want to boost your magnesium levels. These tablets are gluten free with no synthetic dyes or artificial flavorings.

Nature Made Magnesium Oxide Tablets Key Features: 

  • Free from major allergens, such as gluten, eggs, and milk
  • Contains natural dyes only
  • 100 tablets to a bottle

Best Magnesium Supplement Spray: Seven Minerals Pure Magnesium Oil Spray

Best Magnesium Supplement Spray

Seven Minerals Pure Magnesium Oil Spray

Get your magnesium with no swallowing of tablets or capsules.

We mentioned above how magnesium oxide isn’t the most bioavailable form of magnesium out there. Seven Minerals Pure Magnesium Oil Spray contains magnesium chloride, which is well-absorbed by the body and can even be absorbed via the skin, which is why this magnesium spray works topically. It’s especially great for relieving muscle cramps and other topical uses, such as headaches and joint pain. However, it can be absorbed into your system in general through your skin, so it’s good for anything an oral magnesium supplement works for.

This spray is made from high quality USP grade magnesium and is one of the purest sprays on the market. You can buy a 2 fl oz travel spray for $10, a 12 fl oz spray for $20, or a large 64 fl oz refill bottle for $50.

Seven Minerals Pure Magnesium Oil Spray Key Features: 

  • Uses highly bioavailable magnesium chloride
  • Liquid form doesn’t need further processing by your body
  • Money back guarantee if it doesn’t work

Best Magnesium Supplement Powder: Pure Essence Labs Ionic Fizz Magnesium Plus

Best Magnesium Supplement Powder

Pure Essence Labs Ionic Fizz Magnesium Plus

More than just magnesium, this powder makes a nutrient-packed drink.

It’s also possible to get your magnesium in a tasty drink form, such as the Pure Essence Labs Ionic Fizz Magnesium Plus. Not only does it contain 300mg of magnesium per serving, it also contains a range of vitamins and other minerals, including vitamin C, vitamin B6 and B12, a vegan form of vitamin D3, copper, and zinc.

You simply mix it with water to make a drinkable vitamin and mineral supplement. Choose from three flavors: raspberry lemonade, mixed berry, and orange vanilla. A 12-ounce pot contains 2 months worth of servings for one person and costs around $30. You can also buy a smaller 6-ounce pot for $20 if you don’t want to commit to a large one before you know you like it.

Pure Essence Labs Ionic Fizz Magnesium Plus Key Features: 

  • Vegan formula
  • Gluten, milk, egg, and soy free
  • Made in the USA in a cGMP facility

Who Should Buy a Magnesium Supplement

Magnesium occurs naturally in foods such as leafy greens, legumes (beans, peas, and lentils), whole grains, nuts, seeds, tofu, and some fatty fish. If you don’t believe you eat enough of these foods, then you should probably buy and take a magnesium supplement to boost your levels. Some people also find magnesium helps with insomnia and others take it for post-workout recovery.

For those interested in magnesium as a post-workout supplement, you may also want to consider taking a supplement before the workout, too. If that’s the case, you may want to check out The Best Muscle Building Supplements.

Important Features to Consider

A magnesium should have a few important features. Here’s what to consider when selecting a magnesium supplement:

  • Supplement type. You can choose from a range of magnesium supplement types: tablets, capsules, spray, powder, and even chewable or gummy tablets. There may be some difference in absorption levels between supplement types but not enough to make a significant difference. More important is to choose a supplement type you’ll reliably use so if you hate swallowing tablets, for instance, try a powder or spray.
  • Magnesium formulation. There are different formulations of magnesium on offer and not all are equally effective. Magnesium oxide is a common choice because it contains the largest amount of elemental magnesium by weight, but its bioavailability is poor. Magnesium citrate and magnesium chloride are more easily absorbed by the body, while magnesium glycinate is especially good for muscle relaxation.
  • Dosage strength. Check the milligrams (mg) of magnesium per tablet, capsule, or serving. Most magnesium supplements contain between 250 and 500 mg. Higher doses are safe (up to about 2,500 mg), but can cause diarrhea.
  • Filler ingredients. Some magnesium supplements, especially tablets, can contain filler ingredients as binders or similar. Most are free from common allergens, such as gluten and dairy, but it’s worth double-checking if you have a food allergy.

Frequently Asked Questions

What is a magnesium supplement and how does it work?

A magnesium supplement is some kind of dietary supplement (such as a tablet or powder) that contains the mineral magnesium. When you take it, it releases magnesium into your bloodstream, boosting the levels contained in your body.

Should you take a magnesium supplement?

Magnesium is an essential mineral that’s involved in all kinds of bodily processes, so you should take a magnesium supplement if you don’t think you’re getting enough in your diet. It’s hard to get too much magnesium (taking 5,000 mg a day or more a day can lead to magnesium toxicity, but most supplements contain 500mg or less and you’re unlikely to get more than the same again from your food) so it’s worth taking a supplement even if you’re unsure whether or not you’re eating enough magnesium-rich foods.

What are the symptoms of low magnesium in the body?

Early signs of low magnesium levels include muscle cramps, fatigue, insomnia, and digestive issues. A serious magnesium deficiency can cause some nasty symptoms, including high blood pressure, an irregular heartbeat, depression, and memory problems.

Does magnesium make you gain weight?

No, it doesn’t. In fact, low levels of magnesium can lead to insulin resistance which is more likely to cause weight gain and, more seriously, is a high-risk factor in type 2 diabetes.
