In the world of essential minerals, magnesium often finds itself overshadowed by its more glamorous counterparts like calcium and iron. Yet, the significance of magnesium in the human body cannot be overstated.

Nutritionists and doctors alike attest to the vital role this unsung hero plays in numerous bodily functions, contributing significantly to overall health.

“Magnesium plays a pivotal role in human health, impacting around 300 enzymatic reactions vital for cellular functions,” Priya Nagwani, renowned nutritionist, tells South First.

Magnesium’s role

Research has illuminated the multifaceted functions of this indispensable mineral. Nagwani elucidates that magnesium serves as a cofactor in the production of adenosine triphosphate (ATP), the body’s primary source of energy.

Without adequate magnesium levels, energy production may falter, leading to fatigue and weakness.

Simultaneously, Shashikant Iyengar, a metabolic health coach, emphasises its role in regulating muscle contractions, making it essential for activities ranging from a casual handshake to intense physical workouts.

“Magnesium also supports the proper functioning of nerve cells, enabling effective communication between the brain and muscles,” Nagwani adds.

Heart health 

Meanwhile, renowned cardiologist Dr Manjunath CN, Director of Jayadeva Institute of Cardiac Sciences in Bengaluru, underscores magnesium’s crucial role in maintaining a healthy heart rhythm.

Magnesium aids in regulating the flow of calcium in and out of heart muscle cells, reducing the risk of arrhythmias and supporting overall cardiovascular health.

Dr Manjunath also highlights magnesium’s ability to relax blood vessels, contributing to the maintenance of healthy blood pressure levels. “Especially in pregnant women with conditions like pre-eclampsia or eclampsia, they will need magnesium to help balance their hypertension,” he notes.

Moreover, doctors affirm that magnesium contributes to maintaining robust bones and preventing osteoporosis.

Do you have enough magnesium?

Determining if you have sufficient magnesium in your system can be challenging, as most of it resides within cells and bones rather than in the bloodstream. However, there are signs that may suggest a deficiency:

  • Muscle cramps and spasms
  • Fatigue and weakness
  • Irregular heartbeat
  • Nausea and vomiting
  • Loss of appetite
  • Numbness or tingling
  • Abnormal heart rhythms

However, Dr Manjunath cautions that magnesium checks are not part of routine blood tests and are not universally recommended. “Only those with conditions like pre-eclampsia or hypertension with arrhythmic heartbeats might be suggested to get their magnesium checked. Only such patients will be asked to take supplements,” he adds.

Nutritionists recommend incorporating magnesium-rich foods into one’s diet to bolster magnesium levels. Leafy greens, such as spinach and kale; nuts and seeds like almonds and pumpkin seeds; whole grains, and beans are excellent dietary sources.
