How do I keep my bones strong after the menopause?
You can protect your bones well after the menopause with hormone therapy, adequate calcium and vitamin D through diet, and regular exercise. Discuss the best approach for your situation with your doctor.
After the menopause, oestrogen levels drop sharply, and this has a direct effect on the bones. The fastest bone loss occurs in the first two to three years. This makes the menopausal period the most important moment to intervene.
Menopausal hormone therapy with oestrogen is the most powerful protection available. It reduces the risk of fractures throughout the body by 20 to 40 percent, and is the only treatment that also works in women who still have a low fracture risk. A patch or gel generally has a more favourable safety profile than a pill. If you also suffer from menopausal symptoms, this is certainly an option worth discussing with your doctor.
Calcium and vitamin D are the second pillar. The strongest results come from fortified dairy products: these increase bone density in the spine, hip and arm, and reduce the risk of a hip fracture. Standalone calcium tablets without vitamin D are not recommended for fracture prevention in postmenopausal women in general. Vitamin K2 also appears to be involved in bone metabolism, but the data are not yet convincing enough for a firm recommendation. Too little is known about magnesium supplements to say anything meaningful about them, unless a deficiency is present.
Exercise has a moderately positive effect on bone mass and helps to prevent falls. The latter is at least as important in osteoporosis as bone density itself. Smoking and more than moderate alcohol use demonstrably cause additional damage to the bones, so stopping or cutting back is an immediate gain.
If you do not benefit from hormone therapy or have a contraindication to it, bisphosphonates such as risedronate are a proven alternative for bone protection and fracture prevention.
This answer draws on several international guidelines and summaries of research into bone health after the menopause. The evidence for hormone therapy and bisphosphonates is solid: multiple large studies confirm fracture reduction. For calcium and vitamin D through diet the evidence is reasonable, and for standalone supplements less consistent. For vitamin K2 and magnesium the evidence is thin and not convincing enough for recommendations.
Does strength training make your bones stronger after the menopause?
Strength training likely makes bones stronger after the menopause, but the effect on bone density is limited in size and the quality of the evidence is low to moderate. Training three times a week with sufficient load, preferably sustained for at least a year, offers the best chance of measurable bone gains.
Why do bones become more brittle after menopause, and what can help?
Menopause causes bone loss because oestrogen disappears and disrupts the balance between bone breakdown and bone formation. Several proven treatments are available, but the choice between them is best discussed with your doctor.
How do I know whether my bones are strong enough (osteoporosis)?
With a bone density scan and, where appropriate, a fracture risk calculation, your GP can check whether your bones are strong enough, especially if you have risk factors or have previously broken a bone from a minor fall.
Is soy good or bad for your bones after menopause?
Soy isoflavones probably do not protect the bones of postmenopausal Western women in any clinically meaningful way. It is better to focus on proven measures such as adequate calcium, vitamin D and exercise.
Does my weight and metabolism change during the menopause transition?
During the menopause transition, your body composition changes profoundly: more fat mass, less muscle and more dangerous abdominal fat. Your total weight on the scale may barely shift, yet something genuinely significant is taking place.
Which supplements actually help with menopause?
Red clover isoflavones and black cohosh have the strongest evidence for reducing hot flashes; soy isoflavones also help to some extent. For bone health, vitamin D is well supported. The effects are modest, and for severe complaints it is best to discuss the options with your doctor.
