Bone Health

Have you ever noticed how your grandmother seems to have gotten shorter over the years, or worried after hearing that a friend's mother broke a wrist from a fall that wouldn't have caused an injury when she was younger? Bone health is one of those things most of us don't think about until something goes wrong, yet the foundations for strong bones are built through nutrition and lifestyle decades before any problem shows up.

In my practice, I find bone health comes up most often around two life stages: for people with a family history of osteoporosis who want to be proactive, and for women approaching or going through menopause, when bone density changes become a genuine concern. The good news is that nutrition, alongside the right kind of exercise, plays a significant role in supporting strong bones throughout life.

Something I find genuinely useful for clients to understand is the concept of 'peak bone mass'. Most of us build the majority of our bone density by our late twenties to early thirties, after which the focus shifts from building to maintaining what we have, and eventually managing natural age-related loss. This means the foods and habits you put in place now matter, whatever age you're starting from, whether that's building peak bone mass in your twenties or protecting what you already have from your forties onwards.

The key nutrients your bones rely on

Bone is living tissue that's constantly being broken down and rebuilt, and it depends on a handful of key nutrients to do this well:

• Calcium – the main structural mineral in bone, found in dairy foods, fortified plant milks, tinned fish with bones (like sardines), tofu, and leafy greens such as kale
• Vitamin D – essential for calcium absorption; the UK's limited sunshine means most adults are advised to consider a supplement, particularly over autumn and winter, alongside food sources like oily fish and eggs
• Vitamin K2 – involved in directing calcium to the bones rather than soft tissue, found in fermented foods and in small amounts in eggs and cheese
• Magnesium – supports bone structure and works alongside calcium and vitamin D; found in nuts, seeds, wholegrains and leafy greens
• Protein – bone is around half protein by volume, so adequate intake from foods like eggs, fish, pulses, dairy and lean meat matters more than people often realise

NHS guidance suggests most adults need around 700mg of calcium a day, roughly the amount in a pint of milk, though needs can be higher at certain life stages. I always encourage clients to think about this as a running total across the day rather than one big dose, since your body absorbs calcium more effectively in smaller amounts spread across meals. If you're dairy-free, this is easily achievable through calcium-set tofu, fortified plant milks, tinned fish eaten with the bones, and leafy greens, so there's no need to worry that avoiding dairy automatically means your bone health will suffer.

Why exercise matters just as much as diet

Nutrition alone isn't the whole picture. Bones respond to load, meaning weight-bearing and resistance exercise, like walking briskly, dancing, climbing stairs or strength training, sends a signal to your body that bone strength needs to be maintained or built. I always encourage clients to think of diet and movement as a partnership rather than treating one as a substitute for the other. Even a daily walk, combined with a couple of sessions of resistance-based exercise each week, can make a meaningful difference over time.

Bone health at menopause

Bone health becomes particularly relevant around menopause, because oestrogen plays a protective role in maintaining bone density, and levels decline significantly during this transition. This can lead to a period of more rapid bone loss, which is one of the reasons calcium, vitamin D and protein intake deserve extra attention at this life stage, alongside the weight-bearing exercise mentioned above. If you're navigating this transition, it's worth looking at nutritionist support through menopause, since bone health is just one part of a wider picture that includes energy levels, mood and metabolic changes too.

It's also worth remembering that bone health isn't only an issue for later life. Building strong bones during childhood and the teenage years, when the skeleton is growing fastest, sets the foundation for decades to come, so if you're thinking about this for your family too, it's worth considering children's nutrition alongside your own, particularly around calcium and vitamin D-rich foods during the school years.

When a DEXA scan reveals an unsettling T-score or perimenopause accelerates bone loss, simply swallowing daily calcium chews is rarely enough. True bone remodelling relies on precise co-factors, gut absorption, and dietary protein working in harmony.
