Did you know that magnesium is a crucial mineral for maintaining a healthy heart? It’s true – this often overlooked nutrient plays a vital role in many of the body’s functions, including regulating heart rhythm and maintaining healthy blood pressure levels.
While many of us are aware of the importance of eating a balanced diet and getting regular exercise for heart health, the role of specific nutrients like magnesium is not always well-known. Yet, studies have shown that magnesium deficiency can increase the risk of heart disease and other cardiovascular issues.
In this article, we’ll explore the many ways in which magnesium supports heart health, as well as the signs of deficiency and how to ensure you’re getting enough of this vital mineral in your diet. Whether you’re looking to prevent heart disease or simply maintain optimal heart function, understanding the importance of magnesium is a crucial step towards achieving your goals.
Magnesium is Essential for a Healthy Heart
- Magnesium is a mineral that is present in large quantities in the body and plays a role in over 600 biochemical reactions. Studies indicate that even a mild deficiency of magnesium can have negative effects on heart health.
- Magnesium is essential for proper cellular metabolic function and mitochondrial health. Studies have shown that magnesium deficiency is strongly linked to heart disease.
- Magnesium plays a vital role in chromosome folding, which enables cellular division, multiplication, and regeneration to compensate for the loss or damage of cells.
- It is recommended to monitor your RBC magnesium levels and symptoms of magnesium insufficiency to determine the appropriate amount of magnesium needed. Low levels of potassium and calcium in lab results are commonly associated with magnesium deficiency.
- To increase magnesium levels, consuming foods high in magnesium or taking a magnesium supplement is recommended. Additionally, taking Epsom salt baths can also be an effective method for boosting magnesium levels.
Magnesium deficiency is a prevalent issue, and recent studies indicate that even mild deficiency can impact heart health. Magnesium plays a crucial role in brain health, cellular function, detoxification, and the optimization of mitochondria. Overall, magnesium has significant potential to impact general well-being, particularly in terms of preventing heart disease and cancer, as well as improving energy and athletic performance.
Why You Need Magnesium
Magnesium is a mineral that ranks fourth in abundance in the human body and participates in over 600 biochemical reactions. One of its vital functions is to play a significant role in:
- Creation of adenosine triphosphate (ATP), the energy currency of your body1,2
- Mitochondrial function and health. Magnesium is required both for increasing the number of mitochondria in your cells and for increasingmitochondrial efficiency
- Relaxation of blood vessels and normalizing blood pressure
Magnesium deficiency, even at subclinical levels, can have negative effects on heart health.
A deficiency in magnesium can result in various health issues as it is necessary for the proper functioning of most cells in the body.
Consuming this is beneficial for heart health, aiding in the maintenance of normal blood pressure and providing protection against stroke.
A 2013 scientific review, which incorporated studies from as early as 1937, concluded that low magnesium levels could be a more accurate predictor of heart disease than cholesterol or saturated fat intake. Lead author Andrea Rosanoff, Ph.D., informed journalists of this finding.
Several studies have shown a correlation between low magnesium levels and cardiovascular risk factors such as high blood pressure, cholesterol, atherogenesis, and calcification of soft tissues.
In recent years, there has been a focus on reducing cholesterol and avoiding a high saturated-fat diet. However, some experts suggest that low magnesium may be the true culprit.
Dr. Sanjay Gupta, a British cardiologist, states that magnesium supports heart health in multiple ways. It fights inflammation, which can prevent hardening of your arteries and high blood pressure. It relaxes your arteries, improving blood flow, and prevents blood from thickening, making it flow more smoothly. These effects are all crucial for optimal heart function.
The Open Heart journal recently published a paper that cautions about the potential cardiovascular risks associated with subclinical deficiency, as outlined by the authors.
Research indicates that supplementing with at least 300 mg of magnesium can lead to increased serum magnesium concentrations and lowered risk of chronic diseases for many individuals.
The recommended dietary allowance (RDA) for magnesium is between 300 and 420 mg/day for most people, which can prevent magnesium deficiency. However, it may not be sufficient for optimal health and longevity, which should be the ultimate goal.
Reasearch About Magnesium and Heart Health
Research has shown that there is a correlation between higher levels of magnesium and a decreased risk of disease and mortality.
A 2016 meta-analysis of 40 studies, which included over 1 million participants from nine countries, showed that individuals with the highest magnesium intake had better outcomes compared to those with the least magnesium intake.
The study found a 10% decreased risk of coronary heart disease and a 12% decreased risk of stroke.
There is a 26% reduced risk of developing Type 2 diabetes.
A 100 mg increase in daily magnesium intake resulted in a lower risk for participants.
Research shows that there is a 22% decrease in heart failure and a 7% decrease in stroke.
Diabetes by 19%
All-cause mortality by 10%
Magnesium is an essential nutrient for maintaining the health of mitochondria.
Mitochondria are organelles found inside cells that are responsible for producing adenosine triphosphate (ATP), the main source of energy in the body. Studies indicate that many health issues can be linked to mitochondrial dysfunction.
Mitochondrial function is crucial for overall health, disease prevention, and physical performance, therefore consuming the appropriate nutrients and precursors is imperative.
According to Rhonda Patrick, Ph.D., magnesium is a crucial factor in improving mitochondrial health. Without it, other strategies may not be as effective.
Athletic performance is partly influenced by oxidative capacity, which is related to the mitochondria’s production of ATP through oxygen consumption within the cell. To increase oxidative capacity, magnesium is necessary and can be achieved through two methods.
- Engaging in exercise can increase the total number of mitochondria in your cells, but it is important to have sufficient amounts of magnesium for new mitochondria to be created.
- The process of improving mitochondrial efficiency for repair and ATP production necessitates the presence of magnesium as a co-factor.

Magnesium plays a crucial role in the process of cell division.
According to recent research, magnesium plays a critical role in chromosome folding, which is necessary for cell division, multiplication, and regeneration to replace lost or damaged cells.
The authors state that the findings offer a new mechanism for organizing chromosomes.
Japanese researchers utilized a new ion detector, called magnesium ratiometric indicator for optical imaging (MARIO), to observe the impact of changes in free magnesium ion concentration on chromosome folding within cells. The researchers concluded that:
During cell division, the condensation of chromosomes is facilitated by the neutralization of their negative charge through the presence of free magnesium.
The concentration of magnesium ions increases significantly during cell division, reaching its highest point during the transition from metaphase to anaphase, which is a stage where the cell membrane starts to show signs of dividing into two cells.
There is a correlation between the amount of ATP in a cell and the quantity of free magnesium ions. As the ATP level decreases, the free magnesium level increases, leading to greater chromosome condensation and more effective cell function.
The hypothesis proposed by the authors is that ATP-bound magnesium is released through hydrolysis, which refers to the chemical process of releasing energy stored in ATP.
Most People Are Magnesium-Deficient
Chlorophyll molecules contain magnesium at their center, therefore a lack of fresh leafy greens in your diet may result in insufficient magnesium intake. Even consuming organic whole foods may not guarantee avoidance of magnesium deficiency, due to nutrient depletion in most soils.
The absorption of magnesium depends on the presence of selenium, parathyroid hormone, vitamins B6 and D, while excess intake of ethanol, salt, coffee, and phosphoric acid in soda can hinder it. Additionally, factors such as sweating, stress, lack of sleep, excessive menstruation, and certain drugs, particularly diuretics and proton-pump inhibitors, can deplete the body of magnesium.
Many experts suggest that taking a magnesium supplement may be beneficial, especially if you have the following conditions or concerns.
One may exhibit symptoms of insufficiency or deficiency.
Incorporate frequent bouts of vigorous physical activity into your routine.
Studies indicate that engaging in strenuous physical activity for a period of six to 12 weeks can lead to a deficiency in magnesium, which may be the cause.
Patients who are taking diuretics or medication for hypertension, particularly thiazides, may experience magnesium deficiency that is difficult to detect through serum tests.
Ways to increase your magnesium levels.
The recommended daily intake of magnesium is between 310 to 420 mg, varying with age and gender. However, some experts suggest that 600 to 900 mg per day may be necessary, similar to the magnesium consumption during the Paleolithic era.
Research suggests that a daily intake of 1 to 2 grams (1,000 to 2,000 mg) of elemental magnesium may have potential benefits for individuals exposed to EMF, which cannot always be fully avoided.
The term “elemental” pertains to the amount of pure magnesium contained in each mg or the percentage of actual magnesium, which varies and affects the necessary dosage. Some supplements require a higher dose due to lower magnesium percentage. Typically, supplements provide 10-15% of the total dose as elemental magnesium after considering absorption.
Magnesium threonate is considered to be one of the most effective forms as it has shown to efficiently penetrate cell membranes, including the mitochondria and blood-brain barrier.
Taking Epsom salt baths and consuming magnesium malate can effectively increase magnesium levels in the body. A recommended dosage is two ounces per week for Epsom salt and malic acid found in magnesium malate can aid in ATP production.
A supersaturated solution of Epsom salts is prepared by dissolving 7 tablespoons of the salt into 6 ounces of water and heating it until all the salt has dissolved. It is then applied to the skin and fresh aloe leaves are rubbed over it to dissolve.
Consuming magnesium through Epsom salt baths is a cost-effective and simple method to enhance your magnesium intake, while avoiding its laxative properties and allowing for higher dosages.
For those who support higher doses of magnesium, it is recommended to take it in evenly divided amounts.
To prevent loose stools, take magnesium in doses throughout the day. It can be taken with or without food. If you’re taking calcium, take them together. If you exercise regularly, take your calcium and magnesium in a ratio of one part calcium to two parts magnesium with your pre-workout meal.
The recommended magnesium to calcium ratio is 1-to-1, however, many individuals consume more calcium than magnesium in their diet. Therefore, some may require two to three times more magnesium supplementation than calcium.
Magnesium is typically obtained through food, with high-fiber options being good sources. Leafy greens like spinach, legumes, nuts, seeds, and whole grains are among the recommended sources of magnesium.
Different types of water, including tap, mineral, and bottled, can serve as sources of magnesium. The amount of magnesium present in each brand may vary.
Health Direct provides a list of foods that are rich in magnesium, along with their corresponding amount in milligrams (mg).
- A serving of pumpkin seeds, weighing 30g, contains 156mg.
- 30g of chia seeds contain 111mg.
- almonds, 30g — 80mg
- A serving of boiled spinach, measuring ½ cup, contains 78mg.
- cashews, 30g — 74mg
- A serving of peanuts contains 63mg of a certain nutrient.
- One cup of soymilk contains 61mg.
- One hundred grams of rolled oats, cooked in unsalted water, contain 29 milligrams.
- Two slices of whole wheat bread contain 46mg.
- One cup of cubed avocado contains 44mg.
- One serving of brown rice (½ cup, cooked) contains 42mg.
- One cup of milk contains 24mg.
A high fat diet could potentially reduce the absorption of magnesium from food.
Indicators of insufficient magnesium levels.
To determine magnesium levels and potential deficiencies, individuals can obtain an RBC magnesium test to measure the amount of magnesium in red blood cells. Monitoring signs and symptoms of magnesium deficiency is also recommended, along with keeping track of potassium and calcium levels as they may indicate a deficiency.
Signs and symptoms of magnesium insufficiency include those listed in Dr. Carolyn Dean’s post, “Gauging Magnesium Deficiency Symptoms.” If you frequently experience any of these, it may indicate a need for more magnesium.
Common symptoms may include seizures, muscle spasms (particularly in the calf muscle when stretching), and eye twitches.
The Trousseau sign is assessed by inflating a blood pressure cuff around the arm to measure pressure.

Optimizing magnesium intake can contribute to better health.
It is advisable to obtain magnesium from dietary sources in addition to supplementation. Opting for organic unprocessed foods would be beneficial, however, magnesium depletion in soil may result in low levels even in organic produce. Dark green leafy vegetables contain high levels of magnesium and juicing them is an effective way to increase intake.
Foods that are high in magnesium can improve overall well-being and reduce the chances of chronic illness. It is recommended to incorporate magnesium-rich foods in one’s diet and consider supplementation if necessary, as it is a cost-effective method to decrease the risk of heart disease.
