Ranking the Best Magnesium Supplements of 2023

Table of Contents

Magnesium is an essential mineral that our bodies require to function properly. It helps maintain healthy bones, muscles, and heart health. Check out the best magnesium supplements of 2023.

Magnesium is an essential mineral that helps build bones and muscles. It also helps regulate blood pressure, heart rate, and muscle contractions. It is found naturally in nuts, seeds, beans, and whole grains. Besides, magnesium is also available in supplement form.

The importance of Magnesium Supplements

Magnesium supplements are available in a variety of forms. They include magnesium oxide, magnesium hydroxide, magnesium chloride, magnesium citrate, and magnesium sulfate.

Magnesium oxide is the most common supplemental form (about 60 percent elemental magnesium). It is inexpensive and provides a relatively large amount of essential magnesium per pill (about 60 percent). However, it may have a laxative effect because only a tiny portion of the magnesium is absorbed.

Milk of magnesia contains magnesium hydroxide. It has a high water solubility but usually causes diarrhea when used as a supplement (20 to 30 percent elemental magnesium).

Magnesium chloride (12 percent elemental magnesium) is available in topical preparations as an antiperspirant or for relief from muscle cramps. On the other hand, magnesium lactate (12 percent essential magnesium) has less of a laxative effect than other forms. Typically helps to treat indigestion, heartburn, or upset stomach. They are both highly soluble.

Magnesium citrate is absorbed well and is commonly used as a laxative (10 to 20 percent elemental magnesium).

Moreover, magnesium gluconate has a high percentage of absorption. However, it contains only about 5 percent elemental magnesium. It may be better tolerated than some other forms of magnesium.

Who should buy magnesium?

Magnesium is an essential nutrient that helps boost energy levels, improve moods, help prevent migraines, and even increase bone density. Magnesium supplements may be beneficial for some people who fall into these categories. Among these conditions is male hypogonadism (low testosterone levels) Kallmann syndrome. There are plenty of testosterone boosters available for men who want to increase their levels naturally. However, some people may find that they need an estrogen blocker instead.

Older men with low magnesium levels are at greater risk for having lower androgen levels than younger men. Taking a magnesium supplement may help them raise their testosterone levels. If you have insomnia, magnesium may be helpful for you. Magnesium is essential for healthy bones, but recent research shows that low blood concentrations of magnesium may play a critical role in causing insomnia. For this reason, some people use magnesium supplementation to help them get better rest at night.

It may be helpful for restless leg syndrome (RLS), which causes an intense urge to move one’s legs during restful periods. However, there has been no research into whether magnesium supplements improve RLS symptoms.

How we ranked

We reviewed the top 10 best magnesium supplements based on their ability to provide easily adjustable doses. Magnesium supplements should be taken with meals to avoid gastrointestinal upset.

Some products also include iron, zinc, calcium, vitamin D, and potassium. We looked at how easy it was to adjust the dose and checked out the ingredients list to ensure no potentially harmful substances.

Benefits of Magnesium Supplements

Magnesium supplements used to be called ‘nature’s aspirin’ because it has so many pain-relieving properties. Magnesium is extraordinary, and it is the cheapest and most common of minerals. It can benefit hypertension, kidney disease, irregular heartbeat, migraines, sleeping problems, and premenstrual syndrome. And that’s just for starters…

Besides, magnesium supplements are very helpful in treating bone health, mental health, natural ingredients, physical performance, and more.

Magnesium supplements are necessary for bone health. It is an essential part of the human skeletal system. Magnesium helps keep calcium in the bones where it helps form them and make them strong. When magnesium levels are low in the bloodstream, your body will take what it needs from your bones. 

Magnesium plays a role in mental health as well as physical health. It helps with anxiety, depression, insomnia, ADHD, and other mental disorders.

Magnesium is an essential mineral with many benefits. Food is the most effective way to get magnesium, especially dark-green leafy vegetables, whole grains, nuts, seeds, and legumes. However, some people don’t get enough magnesium in their diet.

Other health benefits of magnesium include:

  • Improves sleep quality
  • Promotes healthy bones and teeth
  • It helps maintain normal heart rhythm
  • Prevents kidney stones
  • Reduces the risk of diabetes
  • Increases insulin sensitivity
  • Relieves anxiety and stress
  • Boosts immunity

Magnesium Deficiency

When you don’t get enough magnesium in your diet, your muscles will become weak and spasm easily. If you have frequent muscle spasms or cramps, or tense muscles that won’t relax, you could be deficient in magnesium. Magnesium is also crucial for regulating blood pressure and heart rhythm. Low levels can contribute to irregular heartbeats and high blood pressure. It also plays a role in blood sugar control. If you have diabetes, taking magnesium supplements regularly can regulate your glucose levels and improve how well your body processes sugar.

Magnesium is involved in more than 300 biochemical reactions in the body, including protein synthesis, muscle and nerve function, blood glucose control, and blood pressure regulation. It also helps promote normal bone formation. Magnesium also plays a vital role in the production of energy.

Some of the health conditions associated with magnesium deficiency include:

  • Brain – Headaches/migraines; insomnia; depression; anxiety; confusion; fatigue; poor memory; irritability
  • Cardiovascular – Blood pressure; irregular heartbeat; arrhythmia
  • Digestive – Constipation/diarrhea; nausea/vomiting
  • Musculoskeletal – Pain
  • Nervous System – Irritability/anxiety/insomnia/mood swings
  • Renal – Frequent urination or loss of bladder control
  • Other – Asthma attacks; tremors or muscle twitches due to low calcium levels

What you need to know about magnesium supplements

Various foods are good sources of magnesium

There are several types of magnesium supplements. They all contain varying amounts of the mineral, depending on their recommended dosage. Magnesium is typically sold in chelated magnesium citrate, magnesium glycinate, orotate, and magnesium taurate.

These forms are absorbed better by the body than other forms of magnesium, so they are recommended for use when trying to increase your intake of the mineral.

Many of the best magnesium supplements on the market come from food sources. Whole grains, nuts, and vegetables are rich in magnesium.

In addition to its role as a cofactor for enzymes involved with energy metabolism, magnesium helps maintain healthy bones and teeth. It can help prevent heart disease by lowering blood pressure and helping to regulate cholesterol levels. And it may play a role in preventing or treating depression and anxiety disorders.

Your RDA for magnesium is 400 milligrams per day. That’s about half of what most Americans consume on average. But there’s no specific upper limit set for this mineral.

You need your age, gender, and other factors.

If you have a family history of high blood pressure or heart disease, getting more than the recommended daily allowance may be beneficial. Consult with your doctor before taking any additional magnesium supplements.

We wanted to find out if there were any supplements the user could adjust to get just enough magnesium without having too high a dose.

We prefer taking our supplements at dosages between 50mg and 150mg daily because splitting larger doses makes them easier to consume throughout the day. However, if you’re willing to experiment with different dosing levels, feel free to go ahead and use whatever works best for you!

Magnesium doses were either too high or too low for products on Google’s organic results pages. Moderate dosages are essential for optimal absorption. Very high dosages are not absorbed because you cannot take too much at once.

We then removed any product that didn’t provide at least 100% of its daily value for magnesium alone. Despite being one of the most popular supplements sold online, Solaray Calcium Magnesia Zinc did not make the grade because they were too expensive for consumers at $40 per bottle. Since these extra ingredients make it hard for you to adjust your magnesium dose, you’ll need to be careful not to exceed recommended amounts of calcium and zinc when using them.

How we rate magnesium supplements?

We rated magnesium supplements by their cost per serving (mg) and whether they were available in a soluble or insoluble form. Magnesium citrate was better than magnesium oxide because it costs less per mg but has similar effects.

Magnesium salts like magnesium citrate and magnesium glycinate rely on your stomach acids to break down their molecules and release the magnesium ions for easier digestion and faster absorption. However, they’re less effective at reducing gastric acid levels than insoluble magnesium supplements.

Metal oxides absorb stomach acids, which means they could potentially be harmful if eaten by someone who has low levels of gastric juice (stomach acid).

We then add any remaining ingredients back into our bowl (minus the salt) until everything has been mixed. Magnesium comes in several forms, including tablets, powders, chews, and liquids. Combining these different types makes for an even easier way to consume magnesium than taking just one type.

Because they contain too much sugar, Natural Vitality Calm gummies are examples of several different magnesium supplements that didn’t make the top 10 list because of their excessive sugar levels.

Recommended dosage of magnesium supplements

Thus far, research is limited. Most studies use around 300 to 500 mg of magnesium per day. The tae kwon do study discussed earlier used a dose of 10 mg of magnesium per kilogram of body mass so that a 150-pound male would take a dose of 680 mg of magnesium per day.

These by-weight formulas help compensate for the fact that more prominent people need a larger dose of medication to get the same effect as a smaller person. Recall that the absorption of magnesium is related to the amount you take. If you tried to take 400 mg of magnesium all at once, your body would not absorb it as well as if you’d split that dose into four or five daily portions (Of course, this doesn’t stop some studies from taking this exact approach the insomnia study on elderly patients conducted in Iran used a straight 500 mg bolus before bed. In practice, this means that less than the total dosage was absorbed.

Keep in mind that your own needs might be lower if your diet is better than average. Indeed, if your diet is good enough, you probably don’t even need a magnesium supplement. The recommended upper limit of magnesium intake from supplements is 350 mg per day for healthy people without a deficiency.

Side effects of Magnesium Supplements

As a water-soluble nutrient that’s ubiquitous in many kinds of foods, the human body is well-equipped to tolerate a range of magnesium intakes.

Magnesium is an essential nutrient for the human body. Magnesium plays a role in more than 300 biochemical reactions in the body. It is necessary to maintain normal bones and teeth, helps regulate muscle and nerve function, promote normal blood pressure, support the immune system, and keep the heart rhythm steady. Magnesium also helps regulate blood sugar levels, promotes normal blood clotting, supports protein synthesis, and helps in energy metabolism.

Magnesium is absorbed best when combined with foods that contain some Vitamin C since Vitamin C increases magnesium absorption. The recommended daily intake for adults between ages 19-30 is 400 milligrams per day with an upper limit of 350 milligrams per day. People older than 30 years are recommended to consume 420 milligrams per day with no upper limits set. However, these are not complex numbers as it depends on individuals’ needs based on their diet and lifestyle choices.

The most common side effect of long-term magnesium supplementation is diarrhea which might be caused by

1) excess magnesium intake

2) taking magnesium together with calcium supplements

3) magnesium oxide (one of the cheapest forms of magnesium).

Other less common side effects include nausea, vomiting, weakness, excessive thirst or urination, weight loss, or gain.

The problem with taking magnesium supplements is you are not getting all of the nutrients your body needs. Magnesium can bind to other nutrients and block them from being absorbed by your body, making it harder for you to get the full benefits of those nutrients. Also, if you take too much of any supplement, your body will excrete what it doesn’t need. Taking too much magnesium can lead to diarrhea and abdominal cramping.


The best magnesium supplements of 2022 will help you get the most bang for your buck. Magnesium is an essential mineral that helps maintain muscle function, protects against heart disease, and promotes bone health. It also plays a role in maintaining normal blood pressure levels.

However, many people don’t consume enough magnesium, leading to fatigue, constipation, and other symptoms. To ensure you’re consuming enough magnesium, try to eat foods high in magnesium, such as nuts, beans, leafy greens, fish, whole grains, and dark chocolate.
