What Is Magnesium?

Magnesium is a remarkable chemical element, represented by Mg and atomic number 12. Its glossy silver-white composition makes it one of the most plentiful elements in our planet’s crust.

Magnesium also plays an essential role in biology, since it acts as a crucial part of numerous enzymes while participating in different cellular activities.

MgMagnesium stands out due to its remarkable lightweight quality. In fact, it’s one of the lightest metals with a density of 1.74 g/cm³- making it perfect for creating alloys that are lighter in weight and applicable across numerous industries, most notably aerospace engineering.

Mg is a highly reactive element that quickly forms compounds with numerous other elements.

For instance, when it comes into contact with oxygen, magnesium oxide – a white powdery compound – is produced; and when exposed to water, magnesium hydroxide, and hydrogen gas emerge as the result.

In the human body, magnesium is an essential mineral that is involved in numerous biological processes. It plays a role in the production of energy, the synthesis of DNA and RNA, the regulation of muscle and nerve function, and the maintenance of healthy bones and teeth.

Leafy green vegetables, nuts, seeds, whole grains, and legumes all contain substantial amounts of magnesium. Unfortunately, though, this essential nutrient is often lacking in people struggling with medical conditions like diabetes or gastrointestinal disorders as well as those who frequently drink alcohol.

The Benefits and Side Effects of Magnesium

Should I take magnesium supplements? Yes. Magnesium is an essential and invaluable mineral needed for human physiological processes to function efficiently. It is important to maintain adequate levels of magnesium for optimal health. Here are some of the benefits and side effects of magnesium:


  • It is vital for keeping bones and teeth healthy. It helps to regulate calcium levels and aids in the absorption of vitamin D, which are both essential for strong bones.
  • It plays a critical role in regulating blood sugar and maintaining optimal health. It aids in the metabolism of glucose, affects insulin sensitivity, and encourages efficient insulin secretion – all essential for managing your blood sugar levels.
  • It has been proven to have a soothing result on the nervous system and can diminish symptoms of both depression and anxiety. With magnesium, you can enjoy peace of mind knowing your mental health is being supported.
  • It is key to soothing muscle cramps and spasms, as well as aiding in proper muscular function and exercise performance. Moreover, it can also help improve sleep quality by encouraging relaxation while lowering stress levels!

Side Effects:

For certain individuals, ingesting high doses of supplements may lead to a bout of diarrhea.

  • Taking magnesium supplements can lead to nausea and vomiting, particularly when taken on an empty stomach. To minimize potential side effects, it is best to take the supplement with food or consult a doctor for further advice.
  • Taking magnesium supplements can lead to unwanted gastrointestinal side effects, such as bloating and gas.
  • For those with low blood pressure, Magnesium supplementation can be incredibly advantageous; however, it can also have an adverse effect on individuals whose blood pressure is already naturally too low.
  • Before taking magnesium supplements, it is essential to have a conversation with your healthcare provider if you are on any other medications. This is because the intake of certain antibiotics and diuretics can interact negatively when taken in conjunction with magnesium supplements.

Ultimately, magnesium is essential for our well-being and has multiple advantages. Although it can be deemed harmless to the majority of people, it’s still necessary to consult with a healthcare professional before taking supplemental doses of magnesium in case there are any existing medical issues or drugs taken.

How to Choose a Magnesium Supplement

After deciding which Mg supplement is most suitable for your needs, it’s time to search for what product will best meet these criteria:

  • High bioavailability: Above all, if you’re consuming a magnesium supplement daily, it should be easy on the stomach. A higher bioavailability level typically means an improved result for long-term usage.
  • Manageable format: If you are taking a magnesium supplement, the number of capsules needed for daily dosage will depend on its design. For some, popping three to four pills won’t be an issue; however, for those who find it bothersome, it might be better to look into other options with more manageable serving sizes.
  • Reasonable price: When shopping for magnesium supplements, you’ll notice a wide range of prices. Basic stand-alone formulations are more cost-effective than blends that contain other nutrients or botanicals to enhance their efficacy. To ensure you’re getting the most bang for your buck, look for premium products with clean ingredients and no GMOs, gluten, dairy, soy, or major food allergens when possible.
  • Safe dosing: Lastly, unless otherwise advised by your physician, opt for a dietary supplement that is at or below the tolerable upper intake level of magnesium.

To reduce the chance of any negative consequences, your healthcare practitioner should always be consulted if higher doses are deemed necessary for medical purposes.

Delivering science-backed doses of magnesium without unnecessary additives, these supplements are the crème de la crème when it comes to convenience and efficiency.

Forms of Magnesium

  • Bisglycinate: The combination of magnesium and two glycine amino acids, magnesium bisglycinate (also sometimes called magnesium glycinate) is one of the most bioavailable forms of magnesium. The combination is easy for the body to absorb, making it gentle on the stomach and GI tract. There are some other forms of magnesium, which we’ll cover below, that are taken specifically to get the bowels moving at high doses. This is not Mg glycinate’s primary design (although all forms of magnesium support digestive motility to some degree). Instead, the amino acid glycine shows the most promise in helping promote high-quality sleep, making a nightly magnesium bisglycinate supplement a good choice for healthy magnesium levels and more restful slumber.
  • Chloride: a blend of magnesium and chlorine, can be extracted from brine or seawater. It has a relatively high bioavailability and is a solid supplement to take if you’re just looking to boost your dietary intake of magnesium.
  • Citrate: A combination of magnesium oxide and citric acid, magnesium citrate can help promote healthy bowel movements. Since it also has a relatively high bioavailability, it, too, can be used as a daily magnesium supplement in the right dose. This form of magnesium dissolves readily in water, making it a popular pick for magnesium powders and liquids.
  • Oxide: The most common (and least expensive) form of magnesium, this one is formed by combining magnesium and oxygen ions. This simple form has a lower absorption rate and is most often taken to encourage bowel movements, and acts as a helpful buffer for other magnesium forms.
  • Malate: Together, magnesium and malic acid are relatively bioavailable and seem to stick around in the bloodstream, for longer than some other forms of magnesium. There is also some anecdotal evidence magnesium malate can promote muscle comfort, but clinical results are mixed.
  • Sulfate: The magnesium and sulfate pairing can be used to replenish electrolytes and encourage bowel movements, and it’s often found in supplements and other remedies like Epsom salts. (Fun fact: The man who brought magnesium to Western medicine was said to be a farmer working in Epsom, England, who noticed that the salts in his well water had soothing effects on his cattle. These days, many people take Epsom salt baths to soothe muscles, though there isn’t much research to back this up.

Consumer Reports

Magnesium users have seen astonishing results in their lives, such as improved moods and reduced anxiety and depression symptoms. Furthermore, users report that magnesium supplements can help reduce muscle cramps and spasms, improve sleep quality, lower blood pressure levels, and minimize migraine intensity & frequency.

However, some users have reported experiencing gastrointestinal side effects such as diarrhea and stomach upset. Therefore, as with any supplement, it is important to consult with a healthcare professional before adding magnesium to your regimen.

  • Almonds (1 ounce): 80mg
  • Avocado (1 medium): 58mg
  • Black beans (1 cup): 120mg
  • Dark chocolate (1 square): 24mg
  • Salmon (3 ounces): 26mg

It’s worth noting that the bioavailability of magnesium can vary depending on the food source and other factors, so it’s important to maintain a varied diet and possibly supplement if necessary to ensure adequate magnesium intake.

Dosage and Usage

While magnesium is naturally found in many foods, some individuals may require additional magnesium supplementation to meet their daily needs. Here are some guidelines for using magnesium supplements:


The recommended daily intake of magnesium varies depending on age and gender. The National Institutes of Health (NIH) recommends the following daily intake levels:

  • Adults 50 years and older: 420-450 mg

Magnesium supplements are available in various forms, such as magnesium oxide, magnesium citrate, and magnesium glycinate.

The amount of magnesium in each supplement can vary, so it is essential to read the label carefully and follow the recommended dosage instructions.

How to use:

  • It is best to take magnesium supplements with food to enhance absorption and reduce the risk of stomach upset.
  • Avoid taking magnesium supplements with other supplements or medications that can interfere with absorption, such as calcium or iron supplements, proton pump inhibitors, or antibiotics.
  • It is best to start with a low dose of magnesium and gradually increase it as needed to avoid digestive discomfort or diarrhea.
  • Always follow the dosage instructions provided by the supplement manufacturer or your healthcare provider.

If you experience any adverse effects or have any concerns about taking magnesium supplements, talk to your healthcare provider.
Overall, magnesium supplements can be a safe and effective way to meet your daily magnesium needs, but it is essential to use them correctly and follow recommended dosages to avoid any potential side effects.

People suffering from kidney issues should be especially mindful of potential side effects, and their physician will advise on how safe taking magnesium may be after assessing one’s health conditions and the medications they are presently using.

What Are the Long Term Effects of Magnesium Supplements?

Magnesium is an essential mineral involved in numerous physiological processes, including muscle function, nerve transmission, and energy production. While magnesium is obtainable from dietary sources like leafy greens, nuts, seeds, and whole grains, many individuals turn to supplements to ensure adequate intake. Understanding the long-term effects of magnesium supplementation is crucial for informed health decisions.

Cardiovascular Health

Long-term magnesium supplementation has demonstrated potential benefits for cardiovascular health. Magnesium plays a key role in regulating blood pressure and maintaining heart rhythm. Studies suggest that consistent magnesium intake can help lower blood pressure in individuals with hypertension and reduce the risk of cardiovascular diseases. Magnesium’s role in promoting vasodilation and preventing arterial stiffness is central to these benefits.

Bone Health

Magnesium is vital for bone health, as it influences the activity of osteoblasts and osteoclasts, the cells responsible for bone formation and resorption. Long-term supplementation has been associated with increased bone mineral density, particularly in postmenopausal women who are at higher risk for osteoporosis. By enhancing calcium absorption and metabolism, magnesium helps maintain strong and healthy bones.

antagonist, helping to modulate synaptic plasticity and neural excitability. Long-term magnesium supplementation has been linked to improved cognitive function and a reduced risk of neurodegenerative diseases such as Alzheimer’s. Furthermore, adequate magnesium levels are essential for managing conditions like migraines, anxiety, and depression.

Metabolic Benefits

Magnesium is a critical component in glucose metabolism and insulin function. Prolonged supplementation can improve insulin sensitivity and lower the risk of type 2 diabetes. Research indicates that magnesium aids in the regulation of blood sugar levels by enhancing the activity of insulin receptors and promoting the efficient use of glucose in the body.

Potential Risks and Considerations

While the benefits are substantial, it’s important to be aware of potential risks associated with long-term magnesium supplementation. Excessive intake, particularly from supplements, can lead to hypermagnesemia, a condition characterized by high levels of magnesium in the blood. Symptoms include nausea, vomiting, low blood pressure, and in severe cases, cardiac arrest. Individuals with kidney dysfunction are at higher risk, as their ability to excrete excess magnesium is impaired.

Magnesium supplements offer several long-term health benefits, particularly for cardiovascular, bone, and neurological health. However, it is essential to balance supplementation with dietary intake and consult healthcare professionals to avoid potential risks. By understanding both the advantages and the precautions, individuals can make informed decisions about their magnesium intake and overall health strategy.
