When it comes to bone health, most people immediately think of calcium and vitamin D. While these are crucial, there’s another often-overlooked nutrient that helps prevent falls and fractures—magnesium.
As we age, maintaining strong bones and preventing falls becomes increasingly important. Falls are one of the leading causes of injuries, hospitalisations, and loss of independence in older adults. However, what many people don’t realise is that poor muscle function, weakened bones, and impaired balance—all factors that contribute to falls—can be linked to low magnesium levels.
If you’re not paying attention to your magnesium intake, you could be missing a crucial element in protecting your bones and reducing your risk of fractures. Let’s explore why magnesium is essential, how it supports bone and muscle health, and how you can ensure you’re getting enough.
The Link Between Magnesium and Bone Strength
Magnesium helps support muscle function, nerve signalling, and bone metabolism. While calcium is often hailed as the key nutrient for bone health, magnesium is just as important for maintaining bone density, strength, and flexibility.
How Magnesium Supports Bone Health
- Enhances Calcium Absorption – Magnesium helps regulate the levels of calcium in the body, making sure that calcium is deposited into bones rather than accumulating in arteries or soft tissues.
- Stimulates Bone Formation – Magnesium plays a role in activating vitamin D, which is important for absorbing calcium and in bone development. Without enough magnesium, vitamin D can’t do its job properly.
- Improves Bone Density – Studies have shown that people with higher magnesium levels have greater bone mineral density, minimising the risk of fractures and osteoporosis.
In fact, research suggests that low magnesium intake is linked with higher risk of fractures—especially in older adults who are already vulnerable to bone loss.
How Magnesium Helps Prevent Falls
Beyond bone health, magnesium also plays a crucial role in muscle function, coordination, and balance—all of which are essential for fall prevention.
Magnesium’s Role in Fall Prevention
- Improves Muscle Strength – Magnesium is essential for proper muscle contraction and relaxation, helping to prevent weakness and instability.
- Enhances Nerve Function – This mineral supports healthy nerve signalling, reducing the likelihood of missteps, loss of coordination, or delayed reflexes.
- Reduces Muscle Cramps and Stiffness – Magnesium deficiency can lead to muscle cramps, tightness, and spasms, which makes movements a lot less fluid and increasing the risk of falls.
- Regulates Blood Pressure and Heart Function – Since magnesium helps maintain stable blood pressure, it reduces dizziness and sudden decline in blood pressure that can cause falls.
Older adults who experience frequent muscle weakness, balance issues, or fatigue may unknowingly be dealing with magnesium deficiency.
Signs You May Be Low in Magnesium
Even though magnesium is found in many foods, deficiency is surprisingly common due to poor dietary habits, high stress levels, and certain medical conditions. Some signs of low magnesium include:
- Muscle cramps or spasms
- Frequent fatigue or low energy
- Weak bones or increased fracture risk
- Numbness or tingling in the limbs
- Poor sleep or restlessness
- Anxiety or mood swings
- High blood pressure
If you experience any of these symptoms, it’s worth evaluating your magnesium intake and making dietary adjustments.
How to Get Enough Magnesium
Unlike calcium, which is supplemented in large doses, magnesium is best obtained through food sources to ensure optimal absorption.
Magnesium-Rich Foods to Add to Your Diet
- Leafy greens – Spinach, kale, and Swiss chard
- Nuts and seeds – Almonds, cashews, pumpkin seeds, and sunflower seeds
- Whole grains – Brown rice, quinoa, oats
- Legumes – Lentils, chickpeas, and black beans
- Avocados – One of the best plant-based sources of magnesium
- Dark chocolate – It has high amounts of magnesium and antioxidants
- Fatty fish – Salmon and mackerel provide magnesium along with omega-3 fatty acids
Adding a variety of these foods into your daily diet can help boost magnesium levels and support overall bone and muscle health.
Should You Take a Magnesium Supplement?
If you struggle to get enough magnesium through food alone, a high-quality magnesium supplement may be beneficial. However, magnesium supplements are made differently..
Best Forms of Magnesium for Absorption:
- Magnesium Glycinate – Best for relaxation, sleep, and muscle recovery
- Magnesium Citrate – Supports digestion and absorption
- Magnesium Malate – Aids in production of energy and in muscle function
- Magnesium L-Threonate – Known for its cognitive and memory benefits
Avoid magnesium oxide, as it has poor absorption and is mainly used as a laxative.
How Much Magnesium Do You Need?
The ideal daily intake of magnesium varies by age and gender:
- Men (31+ years old): 400-420 mg per day
- Women (31+ years old): 310-320 mg per day
If you have existing bone or muscle health concerns, consult a healthcare provider to determine whether boosting your magnesium intake through supplements or food is necessary.
Other Ways to Strengthen Bones and Prevent Falls
- Stay Active with Strength and Balance Exercises
- Weight-bearing exercises (like walking, jogging, or resistance training) help build stronger bones.
- Balance exercises boost coordination and lower the risk of falls.
- Stretching routines keep muscles flexible and prevent stiffness that could contribute to instability.
- Optimise Vitamin D and Calcium Intake
- Magnesium, vitamin D, and calcium work together for optimal bone strength.
- Get sun exposure or take vitamin D supplements if needed.
- Include calcium-rich foods like dairy, tofu, and leafy greens in your diet.
- Keep Your Home Fall-Proof
- Install non-slip mats in bathrooms and kitchens.
- Ensure adequate lighting in hallways and staircases.
- Remove clutter and loose rugs to prevent tripping hazards.
While calcium and vitamin D often take the spotlight in bone health, magnesium is just as important for preventing falls and fractures. This underconsumed nutrient plays a crucial role in bone density, muscle function, and balance, reducing the risk of injuries as we age.
By eating magnesium-rich foods, staying active, and maintaining a balanced diet, you can support long-term bone health and protect yourself from falls—one of the most common risks for older adults.
Taking control of your magnesium intake today could mean stronger bones and better mobility for years to come.

FAQs
How does magnesium compare to calcium for bone health?
Magnesium helps regulate calcium absorption, preventing calcium buildup in soft tissues and ensuring it is deposited into bones where it belongs.
Can I get magnesium from food alone?
Yes, if you eat a diet rich in leafy greens, nuts, seeds, whole grains, and legumes, but many people still don’t reach optimal levels.
Can I take magnesium supplements every day?
Yes, but stick to the recommended dosage to avoid digestive issues. If unsure, consult a doctor before starting a supplement.
