How We Ranked The Top Magnesium Supplements of 2021

Separating magnesium supplements can be challenging. After all, all magnesium supplements contain some dosage of magnesium. Many supplements advertise the same benefits.

To separate the best and worst magnesium supplements from one another, we used the following ranking factors:

Magnesium Dosage

You’re buying a magnesium supplement for the magnesium. That’s why dosage played a role in our rankings. We emphasized magnesium supplements with strong, clinically proven dosages. The upper dosage limit for magnesium supplements is 350mg for adults, so most magnesium supplements contain a maximum dose of around this amount.

Types of Magnesium

Dosage doesn’t tell the whole story. Some types of magnesium are more valuable than others. Some magnesium supplements are associated with different effects. We considered the type of magnesium in our rankings.

Price & Value

Magnesium is a common mineral. There’s no need for supplement companies to charge over $100 per bottle for a magnesium formula. We listed products for all different budgets, although we ensured the manufacturer offered good value at every price range.

Advertised Benefits

When taken in supplement form, magnesium is a crucial mineral that can support bone health, immunity, nerve health, and muscle growth. However, magnesium supplements will not supercharge your body overnight. Supplement companies cannot advertise their products as a cure or preventative measure for diseases. We were wary of magnesium supplement companies with dishonest or exaggerated benefits.

Complementary Ingredients

We primarily considered the dose of magnesium in our rankings. However, we put a slight emphasis on complementary ingredients when used effectively. Many popular magnesium supplements contain zinc and vitamin D3, for example, because the three nutrients have been shown to work in complementary ways.

Manufacturer Reputation & Transparency

Some magnesium supplement companies on this list publish their total lab test results upfront, making it easy to see how the supplement compares to other leading options. Other companies are vague about their sources, making it hard to see where your magnesium comes from. We considered manufacturer transparency, manufacturing location, and overall manufacturer reputation in our rankings.

Types of Magnesium

Many magnesium supplements contain different types of magnesium. Instead of just giving your body one kind of magnesium, you can take multiple types for added benefits.

Most supplements contain one of seven significant forms of magnesium. Here’s a brief explanation of each form of magnesium and how it works:

Magnesium Chelate

This type of magnesium is generally recommended for muscle growth, recovery, and health. Studies show that chelated forms of magnesium have better absorption than non-chelated forms. In one study, researchers found that taking 400mg of chelated magnesium per day can help with symptoms of PMS and foot and leg cramps. If you have cold extremities (like cold hands and feet), then magnesium chelate could help. Overall, it’s known for its superior stability and bioavailability compared to other forms of magnesium listed here.

Magnesium Citrate

Magnesium citrate may help with weight loss and arterial stiffness, according to some studies. Magnesium citrate is simply magnesium combined with citric acid. It’s also one of the most popular types of magnesium in the supplement industry – primarily because it’s also the most absorbable form of magnesium for the body. Like other forms of magnesium, magnesium citrate is essential for the heart, muscles, and bones. Your body also uses it to synthesize RNA and DNA and support intestinal health.

Magnesium Bisglycinate

This type of magnesium is often used to treat symptoms of excess stomach acid, including upset stomach, heartburn, and indigestion. Also known as magnesium glycinate, magnesium bis-glycinate is another popular form of magnesium known for its ability to cross the blood-brain barrier. Manufacturers pair magnesium with an amino acid called glycine is known for its ability to cross the blood-brain barrier. That’s why many magnesium bis-glycinate supplements are advertised explicitly for their effects on sleep, brain health, and anxiety.

Magnesium Malate

Magnesium malate is often called the most bioavailable form of magnesium, which means your body absorbs more of it. This is the form naturally found in fruits. Some studies suggest magnesium malate can help with migraines, chronic pain, and depression. Magnesium malate is one of the more beneficial forms of magnesium for brain and nervous system health, and it’s also one of the most popular options for migraines and similar issues. Other studies have linked magnesium malate to better adenosine triphosphate (ATP) production in the cells, which could help with energy.

Magnesium Sucrosomial

Magnesium sucrosomial can help you produce energy. It’s also been shown to support the immune system, help with bone health and skeletal development, and provide other benefits.

Magnesium Taurate

Magnesium taurate is typically known as the type of magnesium that’s best for your heart. Studies show it could have cardioprotective effects by supporting vascular health. Studies also show your body can easily assimilate magnesium taurate. This form of magnesium is a magnesium salt bound to taurine, an amino acid. Some studies show that magnesium taurate can help with anxiety and heart health more than other forms of magnesium.

Magnesium Orotate

Magnesium orotate is believed to help with metabolism, athletic performance, and muscle recovery after exercise, among other benefits. This form comes from a magnesium salt bound with orotic acid. Some magnesium supplement manufacturers advertise this form as the best type of magnesium supplement for health.

Some of the magnesium supplements above, including Magnesium Breakthrough, contain all seven forms of magnesium. Others include one or two types of magnesium.

How Magnesium Deficiency Works

Magnesium is an essential mineral for overall health and wellness. Unfortunately, millions of Americans don’t get their daily recommended dose of magnesium.

Magnesium deficiency is associated with higher inflammation, leading to heart disease, diabetes, and certain cancers. Low levels of magnesium also seem to be a risk factor for osteoporosis. Additionally, people eating a diet rich in magnesium tend to have lower blood pressure and a lower risk of hypertension.

Severe magnesium deficiency is rare but serious. People with kidney disease, Crohn’s disease, or parathyroid problems are more likely to have serious magnesium deficiencies. Magnesium deficiencies can also occur in older adults, people who abuse alcohol, and people taking certain drugs for diabetes and cancer.

Symptoms of Magnesium Deficiency

Unless you have a severe magnesium deficiency, you’re unlikely to experience symptoms of magnesium deficiency. However, you may notice early warning signs if you’re getting enough magnesium in your diet.

  • Signs of minor magnesium deficiency include:
  • Cramping (particularly in the hands and feet)
  • Other abnormal muscle movements, including tremors, spasms, and involuntary twitches under the skin
  • A general feeling of muscular weakness
  • Mental changes, including mood swings, depression, migraine headaches, anxiety, and impairments in learning and memory

Fortunately, researchers have found that a magnesium-rich diet can reverse all of these symptoms. Even if you’re magnesium deficient today and feeling the symptoms above, a good magnesium supplement or a magnesium-rich diet could help.

Recommended Dosage of Magnesium

Generally, adults need around 300 to 400mg of magnesium per day.

Recommended dietary allowances (RDAs) for magnesium vary based on age and sex. Here’s how much magnesium experts recommend getting per day, according to RDA measurements:


  • 1-3 Years: 80mg per day
  • 4-8 Years: 130mg per day
  • 9-13 Years: 240mg per day


  • 14-18 Years: 360mg per day
  • 19-30 Years: 310mg per day
  • 31+ Years: 320mg per day


  • Under 19 years (400mg per day), 19 to 30 years (350mg per day), and 31+ (360mg per day)


Under 19 years (360mg per day), 19 to 30 years (310mg per day), and 31+ (320mg per day)


  • 14-18 Years: 410mg per day
  • 19-30 Years: 400mg per day
  • 31+ Years: 420mg per day

Best Food Sources of Magnesium

According to the National Institutes of Health, some of the best food sources of magnesium include:

  • Pumpkin seeds (156mg of magnesium / 37% DV per 1 ounce serving)
  • Chia seeds (111mg of magnesium / 26% DV per 1 ounce serving)
  • Almonds (80mg of magnesium / 19% DV per 1 ounce serving)
  • Spinach (78mg of magnesium / 19% DV per ½ cup of boiled spinach)
  • Peanuts (63mg of magnesium / 15% DV in ¼ cup of roasted peanuts)
  • Soymilk (61mg of magnesium / 15% DV in 1 cup serving)
  • Peanut butter (49mg of magnesium / 12% DV in 2 tablespoon serving)

Yogurt, breakfast cereals, oatmeal, bananas, salmon, milk, raisins, avocados, beef, broccoli, rice, and apples also have significant doses of magnesium.

Magnesium Benefits: What Does Science Say?

Magnesium is an essential mineral for health and wellness. Studies have validated the use of magnesium, the risk of magnesium deficiency, and the benefits of a magnesium-rich diet. We’ll explore some of those benefits below to explain how magnesium supplements may be able to help.

One large meta-analysis found that a dose of 300mg of magnesium per day for one month was associated with a reduction in systolic and diastolic blood pressure. In another study, researchers reviewed the evidence on magnesium supplementations. They found that taking 365mg to 450mg of magnesium per day for 1 to 6 months lowered blood pressure in individuals with insulin resistance, type 2 diabetes, and other severe health conditions. Because of these studies and others, many magnesium supplements are advertised to support cardiovascular health.

Some people with diabetes take magnesium supplements, and studies have validated the use of magnesium in some people with diabetes. In this study, researchers found that supplementing with magnesium for four months could improve glucose control and insulin resistance while increasing insulin sensitivity in some individuals. Researchers also found magnesium supplementation was associated with better metabolic health and a reduced risk of type 2 diabetes.

Others take magnesium daily for bone health and osteoporosis. In this study, researchers found that magnesium was associated with increased bone density and a reduced rate of fractures. Because of this study and others, many supplement companies advertise magnesium to support bone health.

Other studies have shown that magnesium can suppress the rate of bone turnover, which is a marker of bone loss. Researchers have observed these effects in healthy young men and postmenopausal women. Researchers believe this effect is linked to the importance of magnesium for vitamin D absorption: your body needs magnesium to absorb and fully activate vitamin D.

There’s some evidence you can use magnesium as a bodybuilding supplement. In this study, researchers found that people with high serum magnesium levels had better grip strength, leg power, jumping performance, and torso mobility. The link was observational, although researchers believe magnesium can improve performance in various types of exercise. Similarly, this study found that magnesium supplements, when added to a strength training program, led to more significant gains. Researchers found magnesium oxide supplementation increased quadriceps muscle torque more than a program with only strength training (without the supplement).

Finally, some studies have linked magnesium to cognitive effects. In this 2010 study, researchers found that magnesium supplementation was associated with better short-term memory, long-term memory, working memory, and overall learning abilities. Meanwhile, this study found that you could reverse mood issues linked to magnesium deficiency by following a high magnesium diet.

Overall, most of the benefits of magnesium supplementation are linked to protective effects – not specific health benefits. Studies show that people who get their daily recommended magnesium intake have better biomarkers of various health measures. If you already get your daily intake of magnesium, then you may not experience more significant benefits through supplementation. However, magnesium-deficient people could particularly benefit from the protective effects of a magnesium supplement.
