Magnesium and magnesium supplements

Magnesium is a micronutrient that is essential for many biological processes in the body. It is the fourth most abundant mineral in the human body and is involved in over 300 biochemical reactions.

Some of the roles of magnesium in the body include:

Muscle and nerve function: Magnesium helps regulate muscle and nerve function by maintaining proper electrolyte balance and supporting nerve impulses.
Energy metabolism: Magnesium is involved in the production and utilization of energy in the body, including the metabolism of carbohydrates and proteins.
Protein synthesis: Magnesium is necessary for the synthesis of proteins in the body, including enzymes and other molecules that play important roles in cellular function.
DNA and RNA synthesis: Magnesium is important for the synthesis of DNA and RNA, which are the genetic building blocks of the body. Magnesium also plays a role in repairing DNA, which undergoes breaks, incidentally making magnesium a significant player in slowing down aging by helping fix broken DNA strands.
Bone health: Magnesium plays a role in bone health by supporting the absorption and metabolism of calcium.
Cardiovascular health: Magnesium is important for cardiovascular health by helping regulate blood pressure and supporting normal heart rhythm.

The body uses magnesium for these and many other functions, and a deficiency in magnesium can lead to a variety of health problems. It is important to maintain adequate magnesium intake through diet or supplements to support optimal health.

How common is magnesium deficiency

Magnesium deficiency is a common issue worldwide, with an estimated 60% of adults in the United States not meeting the recommended daily intake of magnesium (28). Magnesium deficiency is also prevalent in other parts of the world, particularly in low-income countries where access to magnesium-rich foods may be limited (29). However, the exact proportion of the world’s population that is deficient in magnesium is difficult to estimate, as studies have reported varying rates of deficiency depending on the population and geographic region.

Factors that may contribute to magnesium deficiency include poor dietary intake, certain medical conditions such as gastrointestinal disorders or kidney disease, medications that interfere with magnesium absorption, and excessive alcohol consumption (30).

It’s worth noting that not all individuals who have low magnesium levels will necessarily be deficient or experience symptoms of deficiency. Magnesium deficiency is typically diagnosed based on blood tests that measure serum magnesium levels, as well as symptoms such as muscle cramps, weakness, and fatigue. However, some individuals with low magnesium levels may not experience symptoms or may have subclinical deficiencies that are not detected through routine testing.

Magnesium in muscle and nerve function

Magnesium plays a critical role in muscle and nerve function by regulating the flow of ions across cell membranes. Specifically, magnesium helps to maintain the proper balance of calcium and potassium ions in muscle and nerve cells, which is necessary for proper muscle contractions and nerve impulse transmission.

When magnesium levels are low, it can lead to muscle and nerve problems due to a disruption in this balance. For example, low magnesium levels can cause muscle weakness, tremors, and spasms, as well as neurological symptoms such as numbness, tingling, and seizures.

There have been several studies that have investigated the link between magnesium deficiency and muscle and nerve problems. For example:

A study published in the Journal of Clinical Neurophysiology found that patients with low magnesium levels were more likely to experience muscle cramps and fasciculations (muscle twitches) than those with normal magnesium levels (1).
Another study published in the Journal of Neurology found that magnesium supplementation improved muscle strength and reduced muscle pain in patients with fibromyalgia, a chronic pain disorder (2).
A study published in the Journal of the American College of Nutrition found that magnesium supplementation improved nerve conduction velocity in healthy adults, suggesting that it may have a protective effect on nerve function (3).

Magnesium plays a critical role in muscle and nerve function and magnesium deficiency can lead to a range of muscle and nerve problems. It is important to maintain adequate magnesium levels through diet or supplements to support optimal health. A part of lifestyle connected to optimal health is exercise and athletes could benefit from adequate magnesium intake.

Muscles, athletes, and magnesium

Magnesium is an important mineral for athletes, particularly those involved in endurance and strength training activities. It plays a key role in muscle function and energy metabolism, and can also help to prevent cramping and muscle fatigue.

Here are some studies that have investigated the role of magnesium in exercise and muscle building for athletes:

A study published in the Journal of the International Society of Sports Nutrition found that magnesium supplementation improved running performance and reduced muscle damage in male soccer players (4).
Another study published in the Journal of Sports Science and Medicine found that magnesium supplementation improved cycling performance and reduced lactate levels in male cyclists (5).
A review published in the Journal of the American College of Nutrition found that magnesium supplementation improved muscle strength and endurance in older adults (6).
A study published in the Journal of Strength and Conditioning Research found that magnesium supplementation improved muscle power and velocity in female basketball players (7).

Magnesium supplementation can be beneficial for athletes, particularly for improving exercise performance and reducing muscle damage and fatigue. In addition to being important for muscles, magnesium is also important for bone health.

Magnesium and bone health

Magnesium is an important nutrient for bone health and strength because it is required for the formation of bone tissue and the maintenance of bone density. Magnesium plays a key role in bone metabolism, including bone formation, mineralization, and resorption.

Magnesium is involved in the activation of enzymes that are necessary for the production of collagen, a major component of bone tissue. Magnesium also regulates the activity of osteoblasts and osteoclasts, the cells that are responsible for building and breaking down bone tissue. In addition, magnesium is important for the absorption and utilization of calcium, another mineral that is essential for bone health.

Studies have shown that magnesium deficiency can have negative effects on bone health, including decreased bone density and increased risk of fractures. For example:

A study published in the American Journal of Clinical Nutrition found that magnesium intake was positively associated with bone mineral density in men and women (17).
Another study published in the Journal of Bone and Mineral Research found that magnesium supplementation improved bone density and strength in postmenopausal women (18).
A review published in the journal Nutrients found that magnesium deficiency can contribute to the development of osteoporosis and increase the risk of bone fractures (19).

Athletes involved in resistance training may benefit from magnesium supplementation, as it has been shown to improve muscle performance and recovery. Magnesium plays a key role in energy metabolism and muscle contraction, and magnesium deficiency can lead to muscle weakness and fatigue. Studies have also shown that magnesium supplementation can improve muscle strength and power in athletes (20).

Overall, these studies and others suggest that magnesium is important for bone health and strength, and that magnesium deficiency can have negative effects on bone density and fracture risk. Athletes involved in resistance training may benefit from magnesium supplementation to support muscle performance and recovery.

Magnesium and metabolism

Magnesium plays an important role in energy metabolism by acting as a cofactor for several enzymes involved in the production and utilization of energy in the body. It is also involved in maintaining the health of cells and mitochondria, the energy-producing organelles within cells.

Magnesium is necessary for the function of the ATP (adenosine triphosphate) synthase enzyme, which is responsible for producing ATP, the primary energy currency of the body. Magnesium is also involved in the metabolism of carbohydrates and fats, which are important energy sources for the body.

In addition, magnesium helps to maintain the health of cells and mitochondria by protecting against oxidative stress and promoting mitochondrial biogenesis (the production of new mitochondria). Magnesium also helps to regulate calcium levels within cells, which is important for many cellular processes.

When magnesium levels are low, it can lead to a variety of energy-related symptoms, including fatigue, weakness, and decreased exercise performance. There have been several studies that have investigated the link between magnesium deficiency and energy metabolism. For example:

A study published in the Journal of the International Society of Sports Nutrition found that magnesium supplementation improved exercise performance and reduced fatigue in healthy adults (8).
Another study published in the Journal of the American College of Nutrition found that magnesium supplementation improved energy levels and reduced symptoms of fatigue in patients with chronic fatigue syndrome (9).
A review published in the Journal of Nutrition found that magnesium deficiency can lead to decreased energy production and impaired mitochondrial function (10).

There is enough evidence to suggest that magnesium plays an important role in energy metabolism and cellular health and that magnesium deficiency can lead to a range of energy-related symptoms. It is important to maintain adequate magnesium levels through diet or supplements to support optimal energy levels and overall health.

Magnesium as an electrolyte

Electrolytes are minerals that carry an electric charge when dissolved in water. These charged minerals are important for many physiological functions in the body, including maintaining proper fluid balance, regulating muscle and nerve function, and supporting proper hydration.

A study published in the journal Nutrients in 2018 found that magnesium plays a critical role in maintaining proper electrolyte balance in the body and that magnesium deficiency can lead to electrolyte imbalances, which can contribute to a range of health problems, including muscle cramps, cardiovascular disease, and kidney disease(39).
Another study published in the journal Nutrients in 2017 found that magnesium supplementation can improve electrolyte balance and reduce the risk of developing hypertension, or high blood pressure(40).
A review article published in the journal Magnesium Research in 2013 highlighted the importance of magnesium as an electrolyte and summarized the evidence supporting the role of magnesium in maintaining proper fluid and electrolyte balance, as well as its role in supporting nerve and muscle function and cardiovascular health(41).
A study published in the journal PLOS ONE in 2015 found that magnesium supplementation can improve exercise performance and reduce muscle damage and inflammation in athletes, highlighting the importance of magnesium as an electrolyte for proper muscle function(42).

Numerous studies have highlighted the importance of magnesium as an electrolyte, and have shown that magnesium deficiency can lead to a variety of health problems.

Magnesium and protein synthesis

Magnesium plays an important role in protein synthesis, which is the process by which cells build proteins from amino acids. Magnesium is involved in the production of nucleotides, which are the building blocks of DNA and RNA, and are essential for protein synthesis.

Magnesium is also necessary for the activation of enzymes involved in protein synthesis, such as RNA polymerase and aminoacyl-tRNA synthetase. In addition, magnesium is involved in the formation of peptide bonds, which link amino acids together to form proteins.

When magnesium levels are low, it can lead to impaired protein synthesis, which can have a range of negative effects on the body. For example, magnesium deficiency can lead to muscle weakness and wasting, as well as impaired immune function due to decreased production of antibodies and other immune proteins.

There have been several studies that have investigated the link between magnesium deficiency and protein synthesis. For example:

A study published in the Journal of Nutrition found that magnesium deficiency can lead to decreased protein synthesis and impaired muscle function in rats (11).
Another study published in the Journal of Clinical Endocrinology and Metabolism found that magnesium deficiency can lead to decreased insulin-like growth factor-1 (IGF-1) production, which is essential for protein synthesis and muscle growth (12).
A review published in the Journal of Nutrition found that magnesium deficiency can lead to decreased protein synthesis and impaired wound healing in humans (13).

Magnesium plays an important role in protein synthesis, which is an essential process that our body requires to function. Magnesium deficiency can lead to a range of negative effects on the body by impairing our ability to synthesize proteins that are the building blocks of life.

Magnesium and DNA

Magnesium is essential for DNA and RNA synthesis, which is the process by which cells produce new copies of DNA and RNA molecules. Magnesium is involved in the formation of nucleotides, the building blocks of DNA and RNA, and is required for the activation of enzymes involved in DNA and RNA synthesis.

In addition, magnesium plays an important role in protecting DNA from damage and in repairing broken DNA. Magnesium is involved in the regulation of DNA repair pathways and has been shown to enhance the activity of DNA repair enzymes. Magnesium also has antioxidant properties, which help to protect DNA from oxidative damage caused by free radicals.

There have been several studies that have investigated the link between magnesium and DNA protection. For example:

A study published in the Journal of Nutrition found that magnesium supplementation can reduce DNA damage in human lymphocytes, which are a type of white blood cell involved in the immune response (14).
Another study published in the journal Mutation Research found that magnesium can protect against DNA damage caused by exposure to ultraviolet radiation (15).
A review published in the Journal of Nutrition and Metabolism found that magnesium plays an important role in protecting against oxidative stress and DNA damage (16).

DNA and RNA synthesis is hugely important for our cells, as the constant process of cell division can be impaired by cells’ inability to synthesize DNA and RNA. Magnesium plays an important role in protecting DNA from damage and repairing broken DNA. It is important to maintain adequate magnesium levels through diet or supplements to support optimal DNA function and overall health.

Magnesium and beauty

Magnesium is important for maintaining healthy skin, hair, and nails due to its role in several key biological processes. Magnesium is involved in collagen production, which is a protein that gives skin its elasticity and strength. It also helps to regulate inflammation and oxidative stress, which can contribute to skin aging and damage.

There is some evidence to suggest that magnesium deficiency may contribute to premature aging of the skin. A study published in the International Journal of Cosmetic Science found that magnesium deficiency can lead to decreased collagen production and increased skin inflammation, both of which are associated with skin aging (21). Additionally, magnesium deficiency has been linked to oxidative stress, which can damage skin cells and lead to premature aging (22).

In terms of hair and nail health, magnesium is important for maintaining strong, healthy hair and nails. Magnesium is involved in protein synthesis and can help to promote the growth and development of hair and nails. Studies have shown that magnesium supplementation can improve hair and nail health in individuals with magnesium deficiency (23).

There is evidence to suggest that magnesium is important for maintaining healthy skin, hair, and nails, and that magnesium deficiency may contribute to premature aging of the skin.

Magnesium and sleep

Magnesium has been shown to play a role in regulating sleep and promoting deep sleep. One potential mechanism of action is through its involvement in the production of melatonin, a hormone that helps regulate sleep-wake cycles.

Studies have suggested that magnesium supplementation can increase melatonin levels and improve sleep quality in individuals with insomnia or sleep disorders (34, 35). In addition, magnesium has been shown to have a calming effect on the nervous system, which may contribute to its ability to improve sleep (36).

Another potential way that magnesium may help with sleep is through its role in regulating the body’s internal clock, or circadian rhythm. The circadian rhythm is responsible for regulating many physiological processes, including sleep, and disruptions to this rhythm can lead to sleep disturbances and other health problems.

Research has suggested that magnesium may play a role in regulating the expression of genes involved in the circadian rhythm, and that magnesium deficiency may contribute to disruptions in the sleep-wake cycle (37, 38).

In addition to helping with exercise, magnesium also helps with sleep, all of which are very important for slowing down aging. Magnesium is one of the most underappreciated micronutrients that is often neglected. An adequate intake of magnesium either through diet or through supplementation will help prevent accelerated aging.

Magnesium and aging

Magnesium deficiency has been linked to a variety of cellular and molecular changes that can contribute to cellular damage, inflammation, and accelerated aging. Some of the mechanisms by which magnesium deficiency can impact cellular health include:

Oxidative stress,
Inflammation,
Impaired cellular energy metabolism
DNA damage.

Oxidative stress occurs when there is an imbalance between free radicals and antioxidants in the body, which can damage cells and contribute to aging. Magnesium is an essential cofactor for several antioxidant enzymes, and magnesium deficiency can lead to decreased antioxidant activity and increased oxidative stress (24).

Inflammation is another important mechanism by which magnesium deficiency can impact cellular health. Magnesium plays a key role in regulating the immune system and can help to modulate inflammatory responses. Magnesium deficiency has been linked to increased levels of pro-inflammatory cytokines, which can contribute to chronic inflammation and cellular damage (25).

Magnesium is also important for cellular energy metabolism, as it is involved in the production and utilization of ATP, the main energy currency of the cell. Magnesium deficiency can lead to impaired energy metabolism and decreased cellular energy production, which can contribute to cellular damage and aging (26).

Finally, magnesium deficiency has been linked to DNA damage and impaired DNA repair mechanisms, which can contribute to cellular damage and aging. Studies have shown that magnesium deficiency can lead to increased DNA damage and decreased DNA repair capacity (27).

These studies and others suggest that magnesium deficiency can have negative effects on cellular health and contribute to accelerated aging. Maintaining adequate magnesium levels through a balanced diet or supplementation may help to support cellular health and reduce the risk of age-related cellular damage and disease.

Dietary sources of magnesium

Magnesium is found in a wide variety of foods, with some of the best dietary sources including:

Dark leafy greens (such as spinach, kale, and Swiss chard)
Nuts and seeds (such as almonds, cashews, and pumpkin seeds)
Legumes (such as black beans, kidney beans, and lentils)
Whole grains (such as brown rice, quinoa, and whole wheat)
Fish (such as salmon, mackerel, and halibut)
Avocado
Dark chocolate
Bananas

In addition to these foods, certain herbs and spices can also be good sources of magnesium. For example, dried coriander, dill weed, and sage are all rich in magnesium and can be used to season foods.

It’s worth noting that some foods may be better sources of magnesium than others, and the amount of magnesium in a particular food can vary depending on factors such as soil quality and processing methods. For example, whole grains and nuts can be good sources of magnesium, but refined grains and nut butters may not contain as much magnesium.

If you’re looking to increase your magnesium intake, incorporating a variety of magnesium-rich foods into your diet can be a good place to start. Some affordable options include legumes, brown rice, and bananas, while dark leafy greens and nuts can be more expensive. Using herbs and spices to season your food can also be an easy way to boost your magnesium intake.

If you have concerns about your magnesium intake or are considering magnesium supplements.

Magnesium supplements

There are a variety of magnesium supplements available, each with different mechanisms of action and absorption rates. Some common types of magnesium supplements include:

Magnesium oxide: This form of magnesium has a high magnesium content and is often used as a laxative. However, it may not be as well absorbed as other forms of magnesium.
Magnesium citrate: This form of magnesium is well absorbed and is often used to help alleviate constipation.
Magnesium glycinate: This form of magnesium is well absorbed and may be less likely to cause gastrointestinal side effects than other forms.
Magnesium chloride: This form of magnesium is well absorbed and is often used topically in the form of magnesium oil.
Magnesium threonate: This form of magnesium is well absorbed and has been shown to have unique benefits for brain health.

The efficacy of different magnesium supplements for restoring magnesium deficiency can vary depending on factors such as absorption rate and dosage. In general, magnesium citrate and glycinate tend to be well absorbed and effective for raising magnesium levels in the body.

What to take alongside magnesium

In terms of other nutrients that may be helpful for maximizing magnesium intake and efficacy, vitamin D is one key nutrient to consider. Vitamin D is important for the absorption and utilization of magnesium, and studies have suggested that low vitamin D levels may impair magnesium absorption (31).

Additionally, calcium and magnesium have a complex interplay in the body, and it may be beneficial to ensure adequate calcium intake alongside magnesium supplementation. Some studies have suggested that high calcium intake may interfere with magnesium absorption, while others have suggested that a balanced ratio of calcium to magnesium may be important for overall health (32, 33).

Overall, incorporating a variety of magnesium-rich foods into your diet and considering supplements as needed can help to ensure adequate magnesium intake and support overall health and wellness. If you have concerns about magnesium deficiency or are considering magnesium supplements, it’s a good idea to talk to a healthcare provider to determine the best approach for your individual needs.
