The Proven Benefits of Magnesium for Longevity and Healthy Ageing

Magnesium is often overlooked, yet it plays an essential role in maintaining our health and potentially extending our lifespan.

This essential mineral is involved in over 300 biochemical reactions in the body, making it indispensable for everything from energy production to muscle function. But what does the science say about magnesium’s role in longevity? 

What is Magnesium and Why is it Important? 🧠

Magnesium is the fourth most abundant mineral in the human body, following calcium, sodium, and potassium. It’s a powerhouse nutrient that supports a wide range of bodily functions. Here’s why it matters:

  • Energy production: Magnesium helps convert food into usable energy by activating ATP (adenosine triphosphate), the body’s energy currency.
  • Muscle and nerve function: It regulates muscle contractions and ensures nerve signals are transmitted effectively.
  • Blood sugar control: Magnesium improves insulin sensitivity and helps maintain stable glucose levels.
  • Blood pressure regulation: It relaxes blood vessels, contributing to healthy circulation.
  • Bone health: Around 60% of the body’s magnesium is stored in bones, where it supports strength and density.
  • Nervous system function: Magnesium aids in neurotransmitter regulation, which can influence mood and stress levels.

Despite its importance, magnesium deficiency is surprisingly common. Studies suggest that up to 50% of adults in the UK may not meet their daily magnesium needs. This can worsen with age, as absorption decreases and certain medications, like diuretics or proton pump inhibitors, can deplete levels further.

So, how does this mineral tie into living a longer, healthier life? 

Magnesium and Longevity: What the Science Says 🔬

 Magnesium has been linked to several aspects of healthy ageing, from protecting your brain to strengthening your heart. 

1. Magnesium and Cognitive Function 🧠

Cognitive decline is a major concern as we age, with conditions like dementia affecting millions worldwide. Magnesium may help keep your brain sharp well into your later years.

  • A study from the Australian National University followed over 6,000 adults aged 40-73 and found that higher dietary magnesium intake was linked to larger grey matter and hippocampal volumes. These brain regions are vital for memory and learning, and preserving their size is associated with better cognitive health. Participants consuming 550 mg or more of magnesium daily had brain structures resembling those of someone a year younger. Read the study here.

  • Another insight comes from a post on X, which highlighted that middle-aged adults consuming over 196 mg of magnesium daily had a 37% lower risk of dementia compared to those getting less than 174 mg. It also noted that individuals with Alzheimer’s disease often have low plasma magnesium levels. See the post here.

2. Magnesium and Cardiovascular Health ❤️

Heart disease remains a leading cause of death in the UK, but magnesium could be a simple yet powerful ally in protecting your heart.

  • A comprehensive analysis of over 1 million people showed that every 100 mg per day increase in magnesium intake was linked to a 10% reduction in all-cause mortality. It also found a 6% lower risk of death from all causes and a 5% reduction in cancer mortality with the same increase. Read the study here.

  • Magnesium also supports healthy blood pressure. A review of multiple studies found that supplementation led to a small but significant drop in blood pressure, especially in people with hypertension. Read the review here.

3. Magnesium and Bone Health 🦴

Maintaining strong bones is essential for staying active and independent as you age. Magnesium works hand-in-hand with calcium and vitamin D to keep your skeleton robust.

  • Research published in the Journal of Clinical Endocrinology & Metabolism showed that daily magnesium supplementation reduced bone turnover in young adults, helping to preserve bone density. This is particularly relevant for postmenopausal women, who are at higher risk of osteoporosis. Read the study here.

  • Another study found that elderly individuals with higher magnesium intake had greater bone mineral density (BMD), reducing the risk of fractures. Read the study here.

4. Magnesium and Overall Mortality ⚖️

The ultimate measure of longevity is how long we live, and magnesium appears to tip the scales in our favour.

  • A study shared on X revealed that men with the highest magnesium levels had a 40% lower risk of all-cause mortality and a 50% reduced risk of cancer death compared to those with lower levels. See the post here.

  • In a mouse model of progeria—a rare condition causing rapid ageing—magnesium supplementation extended lifespan. While this was an animal study, it hints at magnesium’s broader potential for human longevity. Read the study here.

How Much Magnesium Do You Need? 📊

The amount of magnesium you need depends on your age and sex. The UK’s Office of Dietary Supplements provides these recommended dietary allowances (RDAs):

Males (mg/day)

Females (mg/day)

19-30 years

400

310

31-50 years

Keep in mind that these are general guidelines. Your needs might differ if you’re pregnant, breastfeeding, or managing a health condition that affects magnesium absorption.

How to Get Enough Magnesium 🥬

Getting sufficient magnesium doesn’t have to be complicated. Here are two practical ways to boost your intake:

1. Magnesium-Rich Foods

The best starting point is your diet. Incorporate these magnesium-packed foods into your meals:

  • Leafy greens: Spinach, kale, and Swiss chard are excellent sources.
  • Nuts and seeds: Almonds, cashews, and pumpkin seeds deliver a hefty dose.
  • Whole grains: Opt for brown rice, quinoa, or oats over refined grains.
  • Legumes: Black beans, chickpeas, and lentils are nutrient powerhouses.
  • Fish: Mackerel and salmon provide magnesium alongside omega-3s.

2. Supplements

If your diet falls short, or if you’re at risk of deficiency due to age or medication, supplements can help. Look for bioavailable forms like magnesium glycinate or citrate, which your body absorbs more efficiently.

For a premium option, consider Healthspan Formulas’ longevity supplements. Their Magnesium Complex blends multiple forms of magnesium to optimise absorption, making it an easy way to support your health goals, especially if you’re focused on healthy ageing.

Magnesium and Longevity: A Quick Recap 📝

Magnesium is a cornerstone of healthy ageing, with benefits that span your brain, heart, bones, and beyond. Here’s what we’ve covered:

  1. Brain boost: Higher magnesium intake supports cognitive function and may lower dementia risk.
  2. Heart helper: It regulates blood pressure and reduces cardiovascular mortality.
  3. Bone strength: Magnesium maintains bone density, helping prevent osteoporosis.
  4. Life extender: Adequate levels are linked to lower all-cause mortality.

By prioritising magnesium through diet and, if needed, supplements, you’re investing in a longer, healthier life.
