Strong Bones for Life: The Complete Bone Health Guide for Men and Women

Bone health is rarely something we think about when we’re younger. But as we get older, it often starts to appear on our radar. We may notice we’re not quite as strong or flexible as we used to be, or hear friends and family talking about osteoporosis, arthritis, or broken bones.

Think of your skeleton as the scaffolding that supports your entire body. From your feet to the top of your head, it provides the framework that allows you to stand upright, move with confidence, and protect your vital organs.

But your bones don’t work alone. Together with your muscles, joints, cartilage, tendons, and ligaments, they form your musculoskeletal system—a remarkable network that keeps you moving every day.

The good news is that there’s a lot you can do to support your musculoskeletal system throughout life. While aging is inevitable, many of the factors that influence your bone, muscle, and joint health are within your control. The choices you make today can help you stay active, mobile, and independent for years to come.

Why Does Our Musculoskeletal System Change with Age?

Our musculoskeletal system is remarkably resilient, but like every other part of the body, it also changes over time. From our 30s onwards, the natural balance between building and repairing tissues gradually begins to shift. These changes happen slowly and often go unnoticed for many years.

The tissues that make up your musculoskeletal system are constantly being repaired and renewed. Bones continually remodel themselves, while muscles, cartilage, tendons, and ligaments are all regularly maintained and repaired by your body. As we age, however, these processes become less effective.

At the same time, hormonal changes, reduced physical activity, certain medical conditions, and nutritional deficiencies can all contribute to a gradual decline in musculoskeletal health.

The good news is that this doesn’t mean weaker bones, stiffer joints, or loss of muscle are inevitable. Many of these age-related changes can be slowed—and in some cases partly reversed—through healthy lifestyle choices.

Understanding why these changes occur is the first step towards protecting your musculoskeletal health and maintaining your strength, mobility, and independence as you age.

How Bones Stay Strong: Understanding Bone Remodeling

Many people think of bones as lifeless structures that simply support the body, but they are actually living, active tissues. Throughout our lives, our skeleton is constantly renewing itself through a natural process known as bone remodeling.

Think of it as your body’s ongoing maintenance program. Every day, your body removes tiny amounts of old or damaged bone and replaces them with new, healthy bone. This process helps keep your skeleton strong while repairing the small amounts of wear and tear that naturally occur through everyday activities.

Behind this continuous renewal are two specialized types of bone cells: Osteoclasts break down and remove old bone tissue, while osteoblasts build new bone in its place. In healthy adults, these two processes work together to maintain bone strength and density.

When we’re younger, bone formation generally keeps pace with—or even exceeds—bone breakdown. As we age, however, this balance gradually begins to shift.

The body starts replacing bone more slowly than it removes it, causing bones to become thinner and less dense over time. Hormonal changes, reduced physical activity, poor nutrition, smoking, certain medications, and some medical conditions can all accelerate this process.

Although these changes are a natural part of aging, they don’t happen overnight, and they don’t affect everyone in the same way. The encouraging news is that healthy lifestyle habits—including regular weight-bearing and resistance exercise, eating a balanced diet, and getting enough key nutrients—can help support healthy bone remodeling throughout life.

What Is the Musculoskeletal System?

Bone health isn’t just about your bones. It’s about the entire musculoskeletal system working together to support the body and keep us moving throughout life.

Part of the Musculoskeletal  System	Primary Function
Bones	Provide the body’s framework, protect vital organs, store minerals such as calcium and phosphorus, and produce blood cells.
Muscles	Generate the force needed for movement while helping to support and stabilize the skeleton.
Joints	The connections between bones that allow different types of movement and provide stability.
Cartilage	Provides cushioning and support, helping absorb shock, reduce friction, and protect joints during movement.
Tendons	Strong connective tissues that attach muscles to bones, allowing movement.
Ligaments	Strong bands of connective tissue that stabilise joints and help prevent excessive movement.

Although each part has its own function, they all depend on one another. Healthy bones need strong muscles, healthy joints rely on supportive ligaments and cartilage, and regular movement helps keep the entire system functioning well.

Why Our Musculoskeletal System Changes with Age

Aging affects every part of the musculoskeletal system, not just our bones. While these changes are a normal part of growing older, they can make us more susceptible to fractures, muscle weakness, joint stiffness, and reduced mobility if we don’t take steps to look after ourselves.

Bones may gradually lose density, muscles naturally lose mass and strength, cartilage becomes thinner and less resilient, and tendons and ligaments become less flexible. Together, these changes can affect balance, posture, flexibility, and overall physical function.

The rate at which these changes occur varies from person to person. Although genetics play a role, lifestyle factors such as physical activity, nutrition, smoking, alcohol consumption, and certain medical conditions can all influence how well our musculoskeletal system ages.

How Hormones Affect Bone and Muscle Health

Hormones play an important role in maintaining healthy bones, muscles, and joints throughout life. As hormone levels naturally change with age, they can affect the balance between building and breaking down bone, influence muscle mass and strength, and contribute to changes in joint health.

Although hormonal changes affect everyone as they age, their effects differ between women and men. Both sexes produce estrogen and testosterone, but in different amounts. Together, these hormones play essential roles in maintaining healthy bones, muscles, and joints throughout life.

Women: The Role of Estrogen

Estrogen plays a vital role in maintaining healthy bones and muscles throughout a woman’s life. As estrogen levels decline during menopause, changes to the musculoskeletal system become more noticeable, making bone health an important priority.

Estrogen and Women’s Bone Health
Bone density	Helps maintain bone density by slowing bone breakdown.
Menopause	Bone loss accelerates during the years around menopause as estrogen levels fall.
Muscle health	Declining estrogen may contribute to reduced muscle strength and function.
Joint health	Some women notice increased joint stiffness or aches during and after menopause.
Long-term effect	Lower estrogen increases the risk of osteoporosis and fractures if bone loss becomes significant.
Testosterone	Women also produce small amounts of testosterone, which helps support muscle strength, bone health, energy levels, and overall well-being.

Men: The Role of Testosterone

Testosterone also plays an important role in maintaining healthy bones and muscles. Although testosterone levels usually decline more gradually than estrogen, these changes can still affect musculoskeletal health over time.

Testosterone and Men’s Bone Health
Bone density	Helps maintain bone density and supports healthy bone remodeling.
Muscle health	Supports muscle mass, strength, and physical performance.
Aging	Testosterone levels usually decline gradually with age.
Bone loss	Lower testosterone may contribute to reduced bone density and a higher risk of osteoporosis.
Long-term effect	Osteoporosis is less common in men than in women, but is often underdiagnosed and undertreated.
Estrogen	Men also produce small amounts of estrogen, which plays an important role in maintaining bone density and supporting healthy bone remodeling.

Essential Nutrients for Healthy Bones, Muscles, and Joints

While calcium is often the first nutrient that comes to mind, it’s only one piece of the puzzle. Keeping your musculoskeletal system healthy requires a balanced diet that provides a wide range of vitamins, minerals, protein, healthy fats, and other compounds needed to build, repair, and maintain bones, muscles, joints, cartilage, tendons, and ligaments throughout life.

Alongside well-known nutrients such as calcium, vitamin D, protein, magnesium, and vitamin K, compounds like collagen and hyaluronic acid also play important roles in supporting different parts of the musculoskeletal system.

The table below highlights some of the most important nutrients and their primary roles.

Nutrient / Compound	Primary Role
Calcium	The main mineral that gives bones their strength and structure.
Vitamin D	Helps the body absorb calcium and supports healthy bones and muscle function.
Protein	Essential for building and maintaining muscles and provides the structural framework for bones and connective tissues.
Magnesium	Supports bone formation, muscle function, nerve signalling, and energy production.
Vitamin K	Helps regulate bone mineralisation by directing calcium into bones.
Vitamin C	Essential for collagen production and helps maintain healthy bones, cartilage, tendons, ligaments, and skin.
Omega-3 Fatty Acids	Help support joint health and healthy inflammatory responses throughout the body.
Collagen	The body’s most abundant protein, providing structure and strength to bones, cartilage, tendons, ligaments, and skin.
Hyaluronic Acid	Helps lubricate joints and cushions cartilage, allowing smooth movement.
Creatine	Creatine helps support muscle strength and physical performance, particularly when combined with resistance training.
Glucosamine & Chondroitin	Naturally occurring compounds found in cartilage that are often taken together as supplements to help support joint health. They do not build bone but may help some people with osteoarthritis symptoms.

While these are among the best-known nutrients and compounds involved in musculoskeletal health, they’re not the only ones. 

Other nutrients—including phosphorus, zinc, manganese, copper, boron, and silicon—also help to maintain healthy bones and connective tissues. Deficiencies in these nutrients are less common in people eating a varied, balanced diet.

Where Can You Get These Nutrients Naturally?

No single food contains everything your musculoskeletal system needs. Rather than focusing on individual “superfoods,” aim for a varied, balanced diet that includes dairy or fortified alternatives, lean protein, fish, legumes, whole grains, nuts, seeds, fruit, and plenty of vegetables. Over time, it’s the overall quality of your diet—not any single food—that makes the biggest difference.

Getting enough calcium isn’t just about how much a food contains—how well your body absorbs and retains it matters too. A high-sodium diet can increase calcium loss through urine, so regularly eating large amounts of salty, highly processed foods may not be ideal for bone health.

What you drink can matter too. Some research has linked frequent consumption of carbonated soft drinks—particularly cola—with lower bone density, especially in women. The reason isn’t entirely clear and may involve phosphates, caffeine, or replacing calcium-rich foods and drinks with soda. Carbonation itself doesn’t appear to be the problem, so sparkling water isn’t the same as cola.

Some plant foods, including spinach and beetroot, are high in oxalates, which can bind to calcium and reduce its absorption. There’s no need to avoid these nutritious foods—just make sure you’re also getting calcium from more readily absorbed sources.

While a balanced diet should be the foundation of good musculoskeletal health, some people may benefit from supplements due to a diagnosed deficiency, certain medical conditions, dietary restrictions, or increased nutritional needs.

Calcium, vitamin D, magnesium, creatine, collagen, and glucosamine are among the supplements commonly discussed in relation to bone, muscle, and joint health. If you’re considering taking supplements, speak with your healthcare provider, as individual needs can vary.

Exercise: The Best Investment in Your Musculoskeletal Health

While good nutrition provides the building blocks for healthy bones, muscles, and joints, exercise gives your body a reason to use them. Regular physical activity not only strengthens muscles but also encourages bones to stay strong, improves balance, keeps joints flexible, and helps maintain mobility and independence as we age.

One of the most fascinating things about our skeleton is that bones respond to mechanical stress. Every time we walk, lift a weight, climb stairs, or perform resistance exercises, our bones experience gentle pushing and pulling forces. These forces signal the body to maintain and strengthen bone tissue—a process that helps support healthy bone remodeling throughout life.

Just as importantly, building a strong core helps protect the spine. Your abdominal muscles, back muscles, and pelvis work together to stabilise the body during everyday movements. A stable core improves posture, reduces strain on the back, and creates a solid foundation for the arms and legs to move efficiently.

Rather than focusing on one exercise, aim for a combination of activities that challenge different parts of your musculoskeletal system, including:

• Resistance training, using body weight, resistance bands, machines, free weights, or the natural resistance of water through activities such as Aqua Pilates. Water provides gentle, even resistance while reducing stress on the joints, making it an excellent way to build strength and improve stability. It’s also a popular option for rehabilitation following certain injuries or surgery, although you should always follow the advice of your healthcare provider or physiotherapist.

• Weight-bearing activities, such as walking, hiking, dancing, or stair climbing, which place gentle stress on the skeleton and encourage healthy bone remodeling.

• Balance and coordination exercises, such as heel-to-toe walking, standing on one leg, or tai chi, which help improve stability and are among the most effective ways to reduce the risk of falls.

• Flexibility and mobility exercises, including stretching or yoga, to help maintain joint movement, posture, and overall mobility.

You don’t have to become an athlete to benefit. Even moderate amounts of regular physical activity can make a meaningful difference over time. The key is consistency. Choosing activities you enjoy makes it far more likely that you’ll continue them for years to come.

Everyday Habits That Help Protect Your Musculoskeletal System

Looking after your musculoskeletal system isn’t just about eating the right foods or exercising regularly. Small lifestyle habits can also make a significant difference to your long-term bone, muscle, and joint health.

Maintain a Healthy Body Weight – Why?

Being underweight can increase the risk of bone loss and fractures, while carrying excess weight places additional stress on weight-bearing joints such as the hips and knees. Maintaining a healthy weight helps support both your bones and your joints.

Why Does Smoking or Vaping Affect Your Bones?

Smoking or vaping has been linked to reduced bone density, slower healing, and an increased risk of osteoporosis and fractures. If you smoke or vape, reducing how much you use—or quitting if you’re able to—can benefit your overall health and may also help support your musculoskeletal system.

Can Alcohol Weaken Your Bones?

Regular excessive alcohol consumption can interfere with bone remodeling, increase the risk of falls, and contribute to weaker bones over time. Drinking less alcohol or keeping it within recommended limits may help support healthy bones and muscles. Even small, sustainable changes can make a positive difference over time.

What Does Sleep Have to Do with Bone Health?

Much of your body’s repair and recovery takes place while you sleep. Getting enough good-quality sleep helps support muscle recovery, tissue repair, and overall health.

Why Is Staying Hydrated Important?

Water is essential for every cell in the body, including those that make up muscles, bones, cartilage, and the fluid that lubricates your joints. Drinking enough water also supports overall physical performance and recovery.

Why Sitting Too Much Isn’t Good for Your Musculoskeletal System

Avoid sitting for long periods whenever possible. Regular movement throughout the day helps maintain muscle strength, joint mobility, and circulation, even if it’s just getting up to stretch or taking a short walk every hour.

Manage Stress: Why It Matters

Chronic stress doesn’t just affect your mental well-being—it can also influence your musculoskeletal health. Over time, persistently high cortisol levels may contribute to bone loss, muscle weakness, and slower recovery from injuries. Stress can also make it harder to maintain healthy habits such as exercising regularly, eating a balanced diet, and getting enough sleep. Finding healthy ways to manage stress can therefore benefit both your body and your mind.

Why Do We Shrink as We Age?

Have you ever noticed that people seem a little shorter as they get older? Or perhaps you’ve discovered that you’ve lost a centimeter or two yourself. Many people assume bones shrink with age, but that’s only part of the story.

One of the main reasons we lose height is because the intervertebral discs—the soft, cushion-like discs between the bones of the spine—gradually lose water and become thinner over time. As these discs compress, the spine becomes slightly shorter, leading to a gradual loss of height.

Changes in posture can also make us appear shorter. As the muscles that support the spine weaken and the spine naturally curves with age, many people develop a more rounded upper back, causing them to stoop slightly.

For some people, these age-related changes are compounded by a gradual loss of bone density. If osteoporosis weakens the vertebrae, small compression fractures can occur. These fractures may cause one or more vertebrae to collapse slightly, leading to a more noticeable loss of height over time. Although osteoporosis is more common in women—particularly after menopause—it can also affect men, especially as they get older or have other risk factors for bone loss.

When Should You Speak to Your Healthcare Provider?

While many changes to our bones, muscles, and joints are a normal part of aging, some symptoms shouldn’t be ignored. Early diagnosis and treatment can often help slow progression and reduce the risk of complications.

Consider speaking with your healthcare provider if you:

• notice a significant or rapid loss of height
• develop persistent back, bone, or joint pain
• experience a fracture after a minor fall or injury
• have a family history of osteoporosis
• go through early menopause
• have low testosterone levels or other hormonal conditions that may affect bone health
• take long-term corticosteroid medication
• have concerns about your bone or musculoskeletal health

A sudden or significant loss of height should not be ignored, as it may indicate an underlying condition such as osteoporosis or vertebral compression fractures. 

Your healthcare provider may recommend further assessment, including a bone density scan (DXA scan), to evaluate your bone health and determine whether treatment or lifestyle changes are appropriate.

Lillepin Takeaway

Looking after your musculoskeletal system isn’t about focusing on one nutrient, one exercise, or one stage of life. It’s about adopting healthy habits that support your bones, muscles, joints, tendons, and ligaments every day.

While we can’t stop the aging process, we can influence how well our bodies age. Eating a balanced diet, staying physically active, maintaining a healthy lifestyle, and addressing problems early can all help protect your strength, mobility, and independence for years to come.

It’s never too early—or too late—to start investing in your musculoskeletal health. Small changes made today can help build a stronger, healthier future.
