One in three people who break their hip will be dead within 1 year. After 10 years, only 8.5% will be alive, compared to 39.8% in the general population [1].
Those numbers reflect a broader pattern seen across orthopaedic wards: patients with hip fractures typically have severely weakened bones, and a hip fracture is a marker of deep frailty. The build-up to that moment is decades in the making, and the trouble begins much earlier than most people realize. The good news is that bone loss is largely preventable — and the earlier action is taken, the greater the benefit.

Why Bone Loss Happens
Bone is a living, dynamic tissue. It's constantly undergoing reconstruction — old bone is removed and replaced with new bone. When people are young, this process maintains bone mass and strength. But as the body ages, bone breaks down more quickly than it is replaced. The result: weaker bones [2].
What's surprising is how early this decline begins. During childhood and adolescence, bone mass increases, peaking in the 20s — earlier for women, later for men [3]. After that peak, bone quality starts to slowly decline, with the process becoming noticeable around age 40 [2].
Importantly, bone loss doesn't mean bones are shrinking in size — they're just thinning inside, losing the density that gives them strength. Like termites in wood, the structure remains, but it's hollowed out.
The rate of bone loss also differs between men and women. After menopause, women lose bone at an accelerated rate — 3% to 5% per year for about 5 to 7 years [4].
Globally, around 200 million people have osteoporosis [5]. In the U.S., about 27% of women and 6% of men over age 65 have it [6].
Many assume this is a concern only for older adults. But what is done during earlier decades significantly affects risk later. And when bones become too weak, fractures follow. Only around 40% to 60% of people who fracture their hip recover the ability to live as they did before [6]. The health consequences are enormous.
How to Prevent Bone Loss with Exercise
Fortunately, there is a way to reduce risk: exercise.
Bone, like muscle, adapts to the stress placed on it. When bones are not loaded sufficiently, the cells that build bone become less active while those that break it down become more active [2]. But when bones are loaded — through impact or lifting — bone-building activity increases [2].
One clinical trial showed that a 20-week high-intensity exercise programme significantly improved bone structure in older women [7]. An earlier meta-analysis found that exercise could prevent or reverse about 1% of bone loss per year in women [8].
So what kinds of exercises are most effective?
Research points to combining both external loads (like running and jumping) and internal loads (like weightlifting). This combination is most effective for stimulating bone growth [7].
The takeaway: resistance training, impact training, and high-intensity workouts like jumping exercises are all beneficial [5]. They improve bone density and also increase muscle strength and balance, reducing fall risk.
The Role of Calcium, Vitamin D, and K2
Calcium supplements are often the first thing people reach for when thinking about bone health. But the evidence is more nuanced than most expect.
Some studies show calcium supplements reduce fracture risk [9]. But others — especially those with lower risk of bias — show no benefit at all [9]. And excessive calcium may carry health risks, making routine supplementation a topic worth discussing with a doctor.
The research picture is clearer for three other nutrients: Vitamin D3, Vitamin K2, and Magnesium. Vitamin D3 helps the body absorb calcium efficiently. Vitamin K2 acts as a director, channelling calcium into the bones rather than into soft tissue. And magnesium supports the cellular processes involved in bone formation [10]. Together, these three nutrients help create the internal environment bones need to stay strong.
From the MicroVitamin range
MicroVitamin includes Vitamin D3, Vitamin K2 MK-7, and magnesium glycinate — the three nutrients discussed in this section — alongside 22 other evidence-based ingredients. MicroVitamin.
Still, supplements are not the main event. Exercise is the primary driver of bone adaptation. Nutritional support ensures the necessary raw materials are available, but without the exercise stimulus, supplementation alone is unlikely to preserve bone density.
Lifestyle Risks to Avoid
Two lifestyle factors have a well-established negative effect on bone health: smoking and excess alcohol.
Both have been shown to increase the risk of bone loss and fractures [11].
Smoking accelerates bone loss, while alcohol impairs bone formation. Reducing or eliminating these habits can make a meaningful difference to long-term bone health.
Should You Get a DEXA Scan?
Osteoporosis is a silent condition. Most people don't know they have weak bones until they suffer a fracture. That's where screening comes in.
The most common screening tool is a DEXA scan, which measures bone mineral density. This measurement, combined with risk factors like age and sex, can be used to estimate fracture risk.
But should everyone get screened?
Not necessarily.
According to the U.S. Preventive Services Task Force, women aged 65 and older should be screened. So should younger postmenopausal women at increased risk — for example, those with low body weight, a history of smoking, or a family history of fractures [6].
Screening in these groups has been shown to reduce fracture rates. One meta-analysis showed a 17% lower risk for hip fractures among screened individuals [12].
For men, the evidence is less clear. The task force could not make a firm recommendation due to insufficient data. The decision is best made on an individual basis in consultation with a doctor [6].
What to Do If You're Diagnosed
If screening reveals low bone density, the first line of action remains exercise and nutrition. But for high-risk individuals, doctors may recommend bisphosphonates — a class of medications that slow bone breakdown.
Bisphosphonates can reduce hip fracture risk by around 35% over a period of 2 to 4 years [13]. However, long-term use carries some rare but serious risks, including atypical fractures and osteonecrosis of the jaw [13].
Treatment is therefore a shared decision between patient and doctor, carefully weighing individual risks and benefits.
Final Thoughts
Bone loss is a hidden epidemic that begins much earlier than most people realize — but it is also one of the most preventable. Prioritising high-impact exercise, meeting nutritional needs for D3, K2, and magnesium, and avoiding harmful lifestyle habits are the primary tools for building a strong skeletal foundation. Starting early makes the biggest difference.
