Magnesium: Health Benefits & Types Of Magnesium

What Is Magnesium?

Magnesium is an essential mineral and the fourth most abundant element in the human body, playing a pivotal role in various physiological functions. As the second most abundant intracellular cation after potassium, magnesium is a cofactor in over 300 enzymatic reactions, including those involved in energy metabolism, protein synthesis, and nucleic acid synthesis. 

Approximately half of the body’s magnesium is stored in bones, with the remainder distributed in soft tissues and a small percentage circulating in the blood. Magnesium is crucial for muscle function, nerve transmission, blood pressure regulation, and glucose metabolism, making it vital for maintaining overall health and preventing various diseases.

What Are The Benefits Of Magnesium?

Magnesium, an essential mineral, offers a multitude of health benefits due to its role in various physiological processes. Here are some key health benefits of magnesium:

Magnesium impacts to your body

Magnesium Improves Cardiovascular Health

Magnesium plays a critical role in maintaining cardiovascular health by regulating blood pressure, reducing the risk of atherosclerosis, and preventing cardiac arrhythmias. Low magnesium levels are associated with an increased risk of cardiovascular diseases such as hypertension, coronary artery disease, and heart failure.

Low magnesium levels are closely linked to the development of atherosclerosis. Magnesium deficiency can lead to endothelial dysfunction, which is a key initiating event in atherosclerosis. Low magnesium levels can increase the concentration and oxidative modification of low-density lipoprotein (LDL) cholesterol, promoting inflammation and plaque formation in arteries. Additionally, a study found that individuals with lower serum magnesium levels had significantly higher odds of developing coronary artery calcification, a marker of atherosclerosis.

Moreover, magnesium deficiency is associated with a higher risk of coronary artery disease (CAD). Low serum magnesium levels have been linked to increased coronary artery calcification, a significant predictor of coronary artery disease. For instance, the Atherosclerosis Risk in Communities (ARIC) study demonstrated that lower serum magnesium concentrations were associated with a higher incidence of CAD. Moreover, another study indicated that low serum magnesium is associated with increased carotid intima-media thickness, an early marker of atherosclerosis and cardiovascular risk.

Magnesium Reduces The Risk Of Diabetes and Metabolic Syndrome

Magnesium plays a significant role in glucose metabolism and insulin action. Adequate magnesium intake improves insulin sensitivity and helps regulate blood glucose levels, thus reducing the risk of type 2 diabetes and metabolic syndrome. This is crucial for preventing the development and progression of these metabolic conditions.

How does magnesium lower the risks of diabetes? Firstly, magnesium is vital for the proper functioning of insulin receptors, which allows insulin to effectively manage blood sugar levels. It also acts as a cofactor for enzymes involved in glucose metabolism, enhancing the body’s ability to process and use glucose efficiently.

Moreover, magnesium has anti-inflammatory properties that help reduce chronic inflammation, a factor often linked to insulin resistance and diabetes. It also reduces oxidative stress, protecting insulin receptors from damage. Additionally, magnesium improves lipid profiles by lowering bad cholesterol (LDL) and triglycerides while increasing good cholesterol (HDL), which is beneficial for metabolic health. Lastly, it supports the health and function of beta cells in the pancreas, ensuring efficient insulin production.

Magnesium Improves Bone Health

Magnesium contributes to bone health by regulating calcium and vitamin D levels, which are critical for bone formation and maintenance. Low magnesium levels are linked to osteoporosis and increased fracture risk. Supplementation can improve bone mineral density and reduce the risk of fractures. 

Magnesium plays a crucial role in maintaining and improving bone health by enhancing bone mineral density (BMD), regulating calcium utilisation, and balancing bone formation and resorption. Higher magnesium intake is linked to increased BMD, particularly in the hip and femoral neck, which helps prevent osteoporosis and fractures. Magnesium aids in the proper utilisation of calcium, ensuring it is deposited in bones rather than soft tissues, thus preventing osteoporosis. It also influences bone metabolism by reducing bone resorption and increasing bone formation markers, contributing to stronger bones.

Moreover, magnesium helps suppress inflammatory cytokines, reducing bone resorption and promoting better bone health. It supports the biomineralisation process, crucial for forming strong bone structure, by aiding in the deposition of minerals and collagen in the bone matrix. Ensuring adequate magnesium intake through diet or supplements can significantly improve bone health, making bones stronger and more resilient against osteoporosis and fractures.

Magnesium Improves Mental Health

Magnesium influences brain function and mood regulation, making it beneficial for mental health. It helps reduce symptoms of depression, anxiety, and stress by modulating neurotransmitter activity and brain function. Supplementation with magnesium has shown to improve mental health outcomes and quality of life in individuals experiencing high stress levels.

Magnesium significantly improves mental health by influencing several key mechanisms in the brain. It plays a critical role in neurotransmitter regulation, particularly in managing the balance of glutamate and GABA, which are essential for maintaining mood stability. Magnesium acts as a natural N-methyl-D-aspartate (NMDA) receptor antagonist, reducing excitatory neurotransmission and thus mitigating anxiety and depressive symptoms. 

Additionally, magnesium supports the production and function of serotonin, a neurotransmitter commonly associated with feelings of well-being and happiness. Supplementation with magnesium has been shown to reduce symptoms of depression and anxiety, as well as improve overall quality of life in individuals with low magnesium levels.

Magnesium Boosts Exercise Performance

Magnesium boosts exercise performance through several mechanisms that enhance energy metabolism, muscle function, and recovery. Firstly, it plays a critical role in energy production by participating in the synthesis of adenosine triphosphate (ATP), the primary energy carrier in cells. This helps increase the availability of glucose in the blood, muscle, and brain during exercise, thereby improving endurance and reducing fatigue. 

Additionally, magnesium aids in reducing the accumulation of lactate in muscles, which is a common cause of muscle soreness and fatigue during intense physical activity.

Magnesium also supports muscle function by regulating muscle contractions and maintaining electrolyte balance, which is essential for preventing cramps and enhancing muscle strength. Studies have shown that magnesium supplementation can improve various measures of muscle performance, including grip strength, lower-leg power, and knee extension torque. 

Moreover, magnesium’s anti-inflammatory properties help in reducing inflammation and muscle soreness after exercise, leading to quicker recovery times and better overall performance. Overall, ensuring adequate magnesium intake can significantly enhance exercise performance and recovery, making it a valuable nutrient for athletes and physically active individuals.

What Are The Types Of Magnesium Supplement?

Magnesium supplements come in various forms, each with different absorption rates and uses. The most common magnesium supplements are listed below. 

Magnesium Citrate

Widely used for its high bioavailability, making it easily absorbed by the body. It’s often recommended for improving digestion and alleviating constipation.

Side Effects: May cause diarrhea, abdominal cramps, and nausea in some individuals. 

Magnesium Oxide

Known for its high magnesium content by weight but has lower bioavailability compared to other forms. It’s often used as a laxative or to treat magnesium deficiency.

Side effects: Low bioavailability and may cause digestive issues like diarrhea. 

Magnesium Glycinate

Highly absorbable and gentle on the stomach. It’s commonly recommended for those with magnesium deficiency and for promoting relaxation and sleep.
