Show Your Bones Some Love: How Women 40+ Can Keep Their Skeleton Strong

As women, we often focus on visible health markers—weight, skin, or energy levels—but one critical part of our body is too often overlooked: our bones. Many of us assume that once our bones are formed, that’s it—they’re solid, unchanging, and “set for life.” The reality, though, is very different.
Bones are living tissues, constantly renewing themselves. Cells called osteoclasts break down old bone, while osteoblasts build new bone. During childhood and adolescence, the emphasis is on growth—building strong, dense bones. By your mid to late twenties, you reach peak bone mass, the point at which your skeleton is at its strongest.
After 40, however, the ageing process begins to tip the balance. Bones start to break down faster than they rebuild, and density gradually declines. This natural process can increase the risk of fractures, joint issues, and conditions like osteoporosis.
Osteoporosis: The Silent Thief
Osteoporosis often feels like a distant concern until it’s diagnosed, or worse, until a fracture occurs. Age can quietly erode up to 25% of your skeleton by the time you hit 50. Women are particularly vulnerable after menopause, when falling levels of oestrogen and progesterone accelerate bone loss. Smaller, less dense bones compared to men also increase risk.
Men aren’t immune either; osteoporosis affects roughly one in five men, often triggered by declining testosterone or other underlying health conditions.
Are You at Risk?
While genetics play a role, lifestyle factors can significantly influence bone health. Some key risk factors include:
Previous fragility fracture (breaking a bone from a minor incident)
Family history, such as a maternal hip fracture
Thin or small bone frame
Low levels of sex hormones (oestrogen/progesterone in women, testosterone in men)
Low BMI
Digestive conditions like Crohn’s or coeliac disease
Conditions such as rheumatoid arthritis, hyperthyroidism, and parathyroid disease
Long-term use of steroids, anti-epileptic drugs, or antacids
Excess alcohol intake
Smoking
Low calcium intake
Low vitamin D levels
Lack of weight-bearing exercise
Being aware of these risk factors is the first step to protecting your skeleton.
It’s Not Just About Calcium
Calcium often steals the spotlight when we think of bone health, but the reality is more complex. While calcium is the primary mineral in bones, osteoporosis is rarely just a matter of calcium deficiency.
Other key nutrients include:
Magnesium – critical for bone formation; even mild deficiency can increase osteoporosis risk
Vitamin D – essential for calcium absorption
Boron – assists in incorporating calcium into bones
Vitamin C – supports collagen production
Zinc – helps create new bone cells
Vitamin K2 – prevents calcium loss from bones
Phosphorus – a building material for bones
Supplements can help, but it’s better to tailor intake with the guidance of a qualified nutrition professional and your GP, ensuring your plan fits your unique needs.
Common Diet Mistakes That Weaken Bones
Even with a balanced diet, certain habits can undermine bone health:
Too much refined sugar or carbs – depletes essential minerals
Excess caffeine or alcohol – increases mineral excretion
Cola drinks – high phosphorus content promotes calcium and magnesium loss
Very high protein diets – protein is acid-forming, requiring calcium from bones to neutralise blood pH
Insufficient fruit and vegetables – diets rich in fruit and veg reduce bone turnover and improve density (Prynne CJ et al., 2006)
Foods That Strengthen Your Bones
Rather than relying solely on supplements, food sources provide essential nutrients in forms your body absorbs well.
Calcium-rich foods:
Dark leafy greens: kale, rocket, watercress
Almonds, cheese, yoghurt, broccoli
Seeds: chia, sesame, tahini
Fish with edible bones: sardines, canned salmon
Plant-based proteins: edamame, tofu, whey protein
Vitamin D:
Oily fish: salmon, trout, mackerel, sardines, fresh tuna
Egg yolks, liver, cheese
Vitamin K2:
MK-4: liver, eggs, meat
MK-7: fermented foods like cheese, sauerkraut, natto
Collagen & Vitamin C:
Collagen: bone broth
Vitamin C: broccoli, cauliflower, kale, red pepper, kiwi, strawberries, citrus
Magnesium, Zinc & Phosphorus:
Magnesium: dark chocolate, avocados, almonds, legumes, tofu, seeds, whole grains, leafy greens
Zinc: beef, prawns, spinach, flaxseeds, oysters, pumpkin seeds
Phosphorus: pork, cod, salmon, tuna
Healthy Weight, Happy Bones
Weight matters for bone health—but not just in one direction. Very low-calorie diets (under 1,000 calories/day) can lower bone density, even in normal-weight adults (Villareal et al., 2015). Being underweight, especially around perimenopause, contributes to bone loss (Rav et al., 1999).
Conversely, obesity can impair bone quality and increase fracture risk due to stress on the skeleton (Sundh et al., 2015). Maintaining a healthy weight supports both bone and overall health.
Stress and Your Skeleton
Chronic stress isn’t just mentally draining; it affects your bones, too. Increased levels of the hormone cortisol can reduce calcium absorption, leading to mineral deficiencies and bone loss (Deutsch, 1978).
A robust stress management plan—including relaxation techniques and quality sleep—supports healthy bones and your overall well-being.
Exercise to Strengthen Bones
Weight-bearing exercise is essential for strong bones. Activities where your body supports its weight help maintain bone mineral density and reduce fracture risk. These include:
Walking, dancing, climbing stairs, hiking
Strength training with weights or resistance bands
Sports: tennis, rope skipping, kettlebells, gardening
Exercise also strengthens muscles, improves balance, and reduces falls. The Royal Osteoporosis Society recommends around 50 minutes of moderate weight-bearing activity most days.
The key is choosing activities you enjoy—this makes it sustainable. Start gradually, listen to your body, and consult your GP if you have concerns.
Taking Action
Bones are not just structural—they’re central to your mobility, independence, and quality of life. Nourishing them requires more than a calcium supplement. A balanced diet, adequate nutrients, weight-bearing exercise, healthy body weight, and stress management all play a vital role.
If you’re ready to make your bone health a priority, working with a qualified nutrition professional can make all the difference. Together, we can create a tailored plan that fits your lifestyle and unique needs, ensuring your skeleton stays strong for years to come.
If you want guidance on diet, supplements, and lifestyle choices to strengthen your bones and feel confident in your health beyond 40, I can help. Let’s work together to show your bones some love and keep you moving safely and strongly.
