The Benefits Of Magnesium For Seniors

Why Is Magnesium Important for Seniors?

Magnesium is involved in hundreds of processes throughout the body, including energy production, muscle contraction, nerve signalling and maintaining healthy bones.

These functions are important at every age, but they become particularly relevant as we get older.

Research suggests that older adults are more likely to have inadequate magnesium intake than younger people. Changes in digestion, dietary habits, certain health conditions and medications can all influence magnesium levels.

Fortunately, many everyday foods provide magnesium, making it possible to support healthy intake through a varied diet.

What Are the Benefits of Magnesium for Seniors?

Magnesium has a hand in some pretty important bodily functions, from keeping muscles moving to helping the body produce energy. Researchers are also exploring whether it may offer additional benefits for cognitive health as we age.

Magnesium Supports Muscle Function

Whether you're out in the garden, heading off on a walk or keeping up with the grandkids, your muscles have plenty of work to do.

Magnesium helps regulate muscle contraction and relaxation, working alongside other minerals such as calcium and potassium to support normal muscle function.

Getting enough magnesium helps keep muscles functioning as they should, although supplements aren't a proven solution for age-related muscle loss or everyday cramps unless inadequate magnesium intake is contributing to the problem.

Magnesium Helps Maintain Healthy Bones

Calcium often gets all the attention when it comes to bone health, but magnesium deserves a place in the conversation, too.

A significant proportion of the body's magnesium is stored in bones, where it contributes to their structure and supports normal bone metabolism.

Magnesium also plays a role in processes involving vitamin D and calcium, two nutrients important for maintaining healthy bones.

As bone density changes with age, getting enough magnesium is one piece of the puzzle, alongside regular weight-bearing exercise and adequate protein, calcium and vitamin D.

Can Magnesium Support Cognitive Health in Older Adults?

Keeping your brain healthy is just as important as looking after the rest of your body as you age.

Magnesium supports normal nerve signalling and plays a role in processes involved in brain function.

Research suggests that maintaining adequate magnesium levels may be particularly important for cognitive health in older adults, with potential implications for reducing the risk of neurodegenerative conditions.

Other studies have found associations between magnesium intake and cognitive function, while exploring how magnesium may help protect nerve cells from inflammation and oxidative damage.

While these findings are interesting, they don't establish that magnesium supplements can prevent cognitive decline or conditions such as Alzheimer's disease.

For now, getting enough magnesium remains a sensible part of maintaining a balanced diet as we age.

Magnesium Contributes to Energy Production

Whether you're tackling the gardening, heading out for a walk or chasing after the grandkids, your body needs energy to keep up.

Magnesium helps the body convert food into usable energy through its involvement in cellular energy production.

Of course, taking extra magnesium won't necessarily put an extra spring in your step if you're already getting enough.

Magnesium Supports Normal Heart Function

Your heart works hard for you every day, and magnesium plays a role in keeping it functioning normally.

It contributes to normal heart rhythm and supports processes involved in blood pressure regulation.

Research has explored the relationship between magnesium intake and cardiovascular health, although this doesn't mean magnesium supplements can prevent or treat heart disease.

Getting enough magnesium through a balanced diet is one way to support normal heart function as you age.

Why Are Older Adults More at Risk of Low Magnesium?

Your magnesium requirements don't suddenly increase when you reach a certain age, but getting enough can become more challenging.

There are a few reasons why.

Changes in Magnesium Absorption

As we age, changes in digestive function may affect how efficiently the body absorbs certain nutrients, including magnesium.

Changes in kidney function can also influence how magnesium is regulated.

Changes in Appetite and Diet

Smaller meals, reduced appetite or less variety in the diet can make it harder to get enough essential nutrients.

For some older adults, shopping for groceries or preparing meals can also become more challenging.

Medications and Health Conditions

Certain medications, including some diuretics and medicines used to manage stomach acid, can affect magnesium levels.

Some health conditions can also influence how magnesium is absorbed or how much is lost through urine.

If you take regular medication, it's worth checking with your GP or pharmacist before adding a magnesium supplement.

How Much Magnesium Do Seniors Need Each Day?

According to Australia's Nutrient Reference Values, adults aged 51 and over need:

These recommendations include magnesium from food, drinks and supplements combined.

And here's something you might not expect: magnesium requirements don't increase after age 70. The challenge for some older adults is simply getting enough through their regular diet.

What Are the Signs of Low Magnesium in Older Adults?

Low magnesium can be tricky to recognise because its symptoms often overlap with those of other health conditions.

Possible signs include:

More severe deficiencies can affect normal heart rhythm and other important bodily functions.

Of course, experiencing these symptoms doesn't automatically mean you're low in magnesium.

If you're concerned about magnesium deficiency, speak with your GP rather than attempting to diagnose or treat it yourself.

What Are the Best Magnesium-Rich Foods for Seniors?

The good news is that getting more magnesium into your diet doesn't have to mean overhauling everything on your plate.

Plenty of everyday foods provide magnesium, including:

And you don't need to get too creative in the kitchen. A bowl of porridge topped with seeds, a handful of nuts or some chickpeas added to a salad are all simple ways to bring more magnesium to the table.

Should Seniors Take Magnesium Supplements?

Not necessarily. For many older adults, a varied and balanced diet provides enough magnesium to meet their daily needs.

However, some people may struggle to get enough through food alone, particularly if they have restricted diets, certain health conditions or medications that affect magnesium levels.

In these cases, a healthcare professional may recommend supplementation.

There are several forms available, including magnesium citrate, glycinate and oxide, each with different absorption and digestive characteristics.

Can Seniors Take Magnesium Every Day?

Magnesium is something your body needs every day, but that doesn't mean everyone needs a daily supplement.

Many older adults can meet their requirements through food. If supplementation is needed, the appropriate dose depends on individual health, kidney function and medications.

It's best to check with a healthcare professional before making magnesium supplements part of your daily routine.

Making Magnesium Part of Healthy Ageing

There's no magic ingredient for healthy ageing, but making sure you're getting the nutrients your body needs is a pretty good place to start.

From keeping muscles moving to supporting healthy bones, magnesium has plenty of important jobs to do as we get older.

And the best part? For many people, getting enough can be as simple as making a few small changes to what's on the menu.

If you're concerned about your magnesium intake or thinking about supplementation, your GP or pharmacist can help you work out what's right for you.
