Discover seven benefits of magnesium and learn how this powerhouse nutrient can enhance physical performance and reduce stress.
What is magnesium?
Magnesium is an essential mineral that plays a critical role in muscle function, nerve transmission, and cellular energy production.
It also helps maintain a steady heartbeat, supports healthy bone structure, and assists in regulating balanced blood glucose levels.
While magnesium is found in various foods such as spinach, almonds, and avocados, many individuals don’t consume enough due to modern dietary habits and certain lifestyle factors, which may lead to magnesium deficiency.
Though symptoms and severity can vary, magnesium deficiency may affect muscle performance, mood regulation, and energy levels.
According to the National Institutes of Health (NIH), the recommended dietary allowance (RDA) for magnesium varies by age and gender.1
Here’s how much magnesium you should obtain daily based on gender and age:
- Males, 19-30 years: 400 mg
- Males, 31 years and older: 420 mg
- Females, 19-30 years: 310 mg
- Females, 31 years and older: 320 mg
Because magnesium supports cardiovascular health and has been linked to better blood pressure regulation, it’s important to maintain optimal levels through nutritious whole foods.

7 benefits of magnesium
Although magnesium supports many of the body’s core functions, it’s often overlooked in daily nutrition. From muscle movement to nervous system balance, magnesium is essential for helping your body operate efficiently.
Here are seven health benefits of maintaining optimal magnesium intake.
1. Supports energy production
Magnesium is crucial for helping the body generate energy as it’s needed to activate enzymes that produce adenosine triphosphate (ATP), which is the primary fuel source of the body’s cells and tissues.
Without sufficient magnesium, the cellular ability to convert macronutrients into ATP is impaired, leading to fatigue, reduced endurance, and an overall decline in physical and mental performance.
2. Promotes bone health
Magnesium may help maintain bone structure by regulating calcium transport and supporting vitamin D metabolism.
It also contributes to bone mineral density and is stored primarily in the bones, where it supports long-term skeletal integrity and resilience.
This is supported by a study published in Biometals, which found that those who consistently consumed less magnesium than recommended showed reduced skeletal strength and a greater risk of fractures.2
3. Assists in muscle function
“Magnesium is an essential mineral involved in approximately 800 biochemical reactions in the body, many of which are critical for muscle health,” explains Dr. Berg.
Magnesium works in combination with calcium in muscle function. While calcium triggers muscle contraction, magnesium is needed to relax the muscles afterward, helping to prevent cramping, tightness, and spasms.
Maintaining optimal magnesium levels is vital for preserving skeletal muscle integrity, especially as the body ages.
4. Help maintain balanced nervous system regulation
Magnesium supports a balanced nervous system by regulating neurotransmitters that facilitate nerve signal transmission throughout the brain and body.
Moreover, research published in Frontiers in Endocrinology found that “magnesium helps prevent events that could otherwise lead to intensified inflammation and neuronal injury.” 3
This highlights magnesium’s integral part in protecting nerve cells from overstimulation and stress-related damage, helping to maintain long-term neural stability.
5. Supports healthy blood sugar levels
Evidence published in Diabetes Care showed that magnesium may help lower fasting blood sugar levels, which is crucial for those with diabetes and insulin sensitivity.4
It also revealed positive effects on markers of insulin sensitivity, linked to magnesium’s role in helping insulin bind to its receptors and supporting the movement of glucose into cells.
Additionally, maintaining adequate magnesium levels has been associated with better regulation of carbohydrate metabolism, which is essential for balanced blood sugar control.
6. Promotes cardiovascular health
A study published in Advances in Chronic Kidney Disease has found that low magnesium levels are associated with a greater risk of cardiovascular conditions such as atherosclerosis and arrhythmias.5
Adequate magnesium intake may support optimal heart function by helping regulate nerve signals, heartbeat rhythm, and blood vessel tone.
7. May offer antioxidant effects benefits
Magnesium deficiency has been linked to increased oxidative stress, which occurs when unstable molecules called free radicals damage cells and disrupt normal biological functions.
Lack of magnesium is also associated with elevated oxidative markers that affect lipids, proteins, and DNA. This can increase the risk of chronic diseases such as cardiovascular disease, neurodegeneration, and certain types of cancer.
What causes low magnesium?
Low magnesium can result from various factors that disrupt the body’s ability to absorb or retain this essential mineral.
Inadequate dietary intake is a common cause, especially when meals lack magnesium-rich foods such as leafy green vegetables, nuts, and seeds.
Additionally, certain lifestyle factors, such as excessive alcohol consumption or high levels of physical stress, can reduce magnesium levels by increasing urinary mineral loss.
Individuals with low stomach acid and poor digestive functions, as well as those with intestinal tract disorders, such as Crohn’s disease or celiac disease, may also struggle to absorb magnesium efficiently, leaving them at risk of deficiency.
Certain medications, such as diuretics, proton pump inhibitors (PPIs), and certain antibiotic drugs, may also interfere with magnesium absorption or promote excretion, further contributing to deficiency.
Signs of magnesium deficiency
While mild magnesium deficiency may go unnoticed, more pronounced or prolonged low levels can lead to noticeable physical and neurological signs.
Here are common signs of magnesium deficiency:
- Muscle cramps or spasms
- High blood pressure
- Abdominal and digestive discomfort
- Migraine headaches
- Irregular heartbeat
- Changes in blood sugar regulation
- Numbness or tingling
If you have developed signs of low magnesium or are concerned about your nutritional status, it’s recommended to consult a healthcare provider for an evaluation of your symptoms and personalized advice.
A blood test is typically used to evaluate magnesium status and determine whether additional intake is needed.
