Building bone density after 60 is harder than it was at 30, but it’s far from impossible. The right combination of exercise, nutrition, and sometimes medication can slow bone loss, modestly increase density in key areas, and significantly reduce your fracture risk. The strategy depends on where you’re starting from, so understanding your current bone health is the first step.
Why Bones Weaken After 60
Your skeleton is constantly rebuilding itself. Specialized cells break down old bone while others lay down new bone in its place. This cycle, called remodeling, stays roughly balanced through middle age. After 60, the balance tips: the cells that break bone down become more active, while the cells that build new bone slow down and decline in number. The net result is that you lose more bone than you replace with each remodeling cycle.
Part of the problem is biological. The stem cells that would normally become bone-building cells increasingly turn into fat cells instead, a shift that accelerates with age. At the same time, dying bone cells release signals that recruit even more bone-destroying cells to the area. The internal scaffolding of bone (the spongy, honeycomb-like interior) thins out and develops wider gaps, while the hard outer shell gets thinner too. Over time, this makes bones lighter, more porous, and more prone to fracture, particularly at the hip, spine, and wrist.
For women, estrogen loss after menopause dramatically accelerates this process, which is why bone density screening is recommended for all women at age 65. For men, the evidence on routine screening is less clear, but those with risk factors should discuss testing with their doctor.
Know Your Starting Point: DEXA Scans
A DEXA scan measures your bone mineral density and produces a number called a T-score. A T-score of negative 1 or higher is considered healthy. Between negative 1 and negative 2.5 indicates osteopenia, a milder form of bone loss. A T-score of negative 2.5 or lower points to osteoporosis.
Knowing your T-score matters because it shapes your entire approach. Someone with mild osteopenia may do well with exercise and dietary changes alone. Someone with osteoporosis will likely need medication on top of those lifestyle changes. If you’re over 60 and have never had a scan, it’s worth getting a baseline measurement so you’re not guessing.
Your doctor may also use a tool called FRAX, which estimates your 10-year probability of a major fracture. It factors in your age, sex, weight, smoking status, alcohol use, family history of hip fracture, steroid use, and whether you have conditions like rheumatoid arthritis or type 1 diabetes. Your DEXA result can be plugged in too, making the prediction more precise.
Exercise That Actually Builds Bone
Not all exercise helps bone density equally. Bones respond to mechanical stress: when you load them with impact or resistance, they adapt by becoming denser. Swimming and cycling, while great for cardiovascular health, don’t provide enough skeletal loading to stimulate meaningful bone growth.
The two categories that matter most are weight-bearing exercise and resistance training. Weight-bearing exercise means anything where your feet and legs support your body weight against gravity: walking, hiking, dancing, stair climbing, or low-impact aerobics. The Bone Health and Osteoporosis Foundation recommends 30 minutes of weight-bearing activity on most days of the week. You can split that into shorter sessions throughout the day if a single 30-minute block is too much.
Resistance training, where you push or pull against external weight, is where the stronger evidence lies. A systematic review of high-velocity resistance training in older adults found that two or more sessions per week produced bone density improvements ranging from 0.9% to 5.4% at the lumbar spine, total hip, and femoral neck. Those percentages may sound small, but at an age when the baseline trend is losing bone every year, even a 1 to 2% gain represents a meaningful reversal. Aim for two to three resistance training sessions per week, and don’t be afraid of heavier loads. Light weights with high repetitions are less effective at stimulating bone than moderate to heavy weights with fewer repetitions. If you’re new to this, working with a physical therapist or trainer experienced with older adults is a smart investment.
You don’t need to do everything in one session. Working your arms one day, legs the next, and trunk the day after that is a perfectly reasonable approach if time is limited.
Calcium and Vitamin D Requirements
Calcium is the primary mineral in bone, and your body can’t build new bone without an adequate supply. The recommended daily intake for adults over 60 depends on your age and sex. Men between 51 and 70 need 1,000 mg per day. Women in that same age range need 1,200 mg. After age 70, both men and women should aim for 1,200 mg daily.
Food sources are preferable to supplements when possible. A cup of milk or fortified plant milk provides roughly 300 mg. Yogurt, cheese, canned sardines and salmon (with bones), fortified orange juice, tofu made with calcium sulfate, and leafy greens like kale and bok choy are all good sources. If you can’t consistently reach your target through food, a supplement can fill the gap, but there’s no benefit to exceeding the recommended amount.
Vitamin D is essential because it controls how much calcium your intestines absorb. Without enough vitamin D, you could take all the calcium in the world and still not get it into your bones. Most guidelines recommend 600 to 800 IU per day for adults over 60, though many clinicians suggest higher doses for people who are deficient. A simple blood test can check your levels. Sun exposure helps your body produce vitamin D, but after 60 the skin becomes less efficient at this process, making dietary sources and supplements more important.
Protein and Other Nutrients
Calcium and vitamin D get most of the attention, but protein plays a critical supporting role. About half of bone volume is protein, and inadequate protein intake is associated with lower bone density and increased fracture risk. Older adults often eat less protein than they need. Aiming for a source of protein at every meal (eggs, poultry, fish, beans, dairy, tofu) helps maintain both bone and the muscle that protects it.
Magnesium, vitamin K, and potassium also contribute to bone metabolism. A diet rich in vegetables, fruits, nuts, seeds, and whole grains generally covers these without the need for individual supplements.
Alcohol and Smoking
Regularly drinking three or more alcoholic drinks per day is an established risk factor for osteoporosis and fractures. The FRAX fracture risk calculator specifically flags this threshold. Research shows no significant increase in fracture risk at two drinks per day or fewer, so moderate consumption doesn’t appear to be a major concern. Three or more drinks daily, however, is clearly harmful to bone.
Smoking accelerates bone loss through multiple pathways, including reducing blood supply to bone and interfering with calcium absorption. Current smoking is another independent risk factor in the FRAX model. Quitting at any age provides some benefit.
When Medication Makes Sense
If you have osteoporosis or have already fractured a bone from a minor fall, lifestyle changes alone are usually not enough. Several classes of medication can help, and most work by slowing down the cells that break bone apart. Bisphosphonates are the most commonly prescribed first-line treatment, available as weekly or monthly pills or as an annual infusion. Denosumab is an alternative given as an injection every six months, often used when bisphosphonates aren’t tolerated or kidney function is reduced.
For people with very low bone density, a history of fractures, or bone loss caused by steroid use, bone-building medications may be prescribed. These drugs actively stimulate new bone formation rather than just slowing breakdown. They’re typically used for one to two years because their benefits fade quickly after stopping. Once the course is complete, you’ll usually switch to a bisphosphonate or similar medication to preserve the gains.
The choice of medication depends on the severity of your bone loss, your fracture history, other health conditions, and how well you tolerate specific drugs. What matters from a practical standpoint is that these medications meaningfully reduce fracture risk, and that any bone-building treatment works best when paired with adequate calcium, vitamin D, and exercise.
Putting It All Together
Improving bone density after 60 isn’t about any single intervention. It’s the combination that produces results. Get a DEXA scan to establish your baseline. Build a weekly routine that includes both weight-bearing activity and resistance training at least twice a week. Make sure you’re hitting your calcium and vitamin D targets through food first and supplements if needed. Keep alcohol under three drinks a day. If your T-score puts you in osteoporosis territory, have a direct conversation about medication options.
Progress is slow. Bone remodels on a timeline of months to years, not weeks. A follow-up DEXA scan is typically done one to two years after starting a new treatment or exercise program. Even if your numbers only hold steady rather than climbing, that’s a win at an age when the natural trajectory is downward. The goal isn’t to rebuild the skeleton you had at 30. It’s to make the skeleton you have now as strong and fracture-resistant as possible.
