What happens to your bones after 60

Your bones stop building new density around age 30, and after that they slowly lose more than they gain. In your 60s, this loss picks up speed — especially for women after menopause, when the hormone estrogen (which helps hold calcium in bone) drops sharply. Men lose bone density more slowly, but they lose it too. The result is that bones become more porous and brittle, which means a fall that would have bruised you at 40 can break you at 65.

The good news is that bone loss is not inevitable or unstoppable. Exercise, calcium, vitamin D, and sometimes medication can slow the loss and even rebuild some density. The earlier you start, the more you can prevent, but it is never too late to make a difference.

Key Takeaways

  • Bone density peaks in your 30s and declines after that, but exercise and nutrition can slow or partially reverse the loss in your 60s.
  • Weight-bearing exercise (walking, dancing, climbing stairs) and strength training are the most powerful tools you have, because they directly signal your bones to stay strong.
  • Most people over 60 need 1,200 mg of calcium and 800 to 1,000 IU of vitamin D daily, but the amount varies by sex and individual factors.
  • A bone density scan (DEXA scan) tells you whether you have normal bone density, osteopenia (mild loss), or osteoporosis (significant loss), and helps your doctor decide on treatment.
  • Falls are the real danger in your 60s — preventing them through balance work, home safety, and vision checks matters as much as building bone.

Exercise that actually strengthens bone

Bone responds to stress by getting stronger. When you put weight on a bone or pull on it with muscle, your body rebuilds it denser. This is why astronauts lose bone in space — without gravity, their bones have no load to carry. You do not need to become an athlete, but you do need to move in ways that challenge your skeleton.

Weight-bearing exercise means your feet or legs carry your body weight against gravity. Walking, dancing, climbing stairs, and hiking all count. Aim for 30 minutes most days of the week. If you have joint pain or arthritis, water aerobics and swimming are gentler on joints but still work your bones because you are moving your body weight through space.

Strength training pulls on bone through muscle attachment, which is a different signal than weight-bearing alone. You do not need heavy weights. Resistance bands, light dumbbells, or your own body weight (like push-ups against a wall or squats) work. Two to three sessions a week, 8 to 10 exercises targeting major muscle groups, is enough. A physical therapist or trainer can show you safe form for your joints.

Balance work is not about bone directly, but it prevents the falls that break bones. Tai chi, yoga, and straightforward exercises like standing on one foot while brushing your teeth all train your body to catch itself. This matters more in your 60s than building perfect bone density, because a strong bone that does not break is only useful if you do not fall.

Getting enough calcium and vitamin D

Calcium is the mineral your bones are made of. Vitamin D is the hormone that lets your gut absorb calcium. Without enough of either, your bones cannot stay strong no matter how much you exercise. Most adults over 60 need 1,200 mg of calcium daily and 800 to 1,000 IU of vitamin D daily, though some people need more based on their sex, weight, and other factors.

Calcium comes from dairy (milk, yogurt, cheese), leafy greens (kale, collards, bok choy), fortified plant milks, canned fish with bones (salmon, sardines), almonds, and tofu made with calcium sulfate. A cup of milk has about 300 mg; a cup of yogurt has 200 to 450 mg depending on the type; a cup of cooked kale has about 180 mg. If you cannot eat enough through food, a supplement fills the gap. Calcium supplements work best when taken with food and in doses of 500 mg or less at a time, because your body absorbs more that way.

Vitamin D comes from fatty fish (salmon, mackerel, sardines), egg yolks, and fortified milk and cereals. Your skin also makes vitamin D when exposed to sunlight, but after 60 your skin is less efficient at this, and many people do not spend enough time in the sun. Most people over 60 need a supplement. Vitamin D3 (cholecalciferol) is more effective than D2 (ergocalciferol). Ask your doctor whether 800 to 1,000 IU daily is right for you, or whether you need more — some doctors recommend higher doses for people with osteoporosis.

Getting a bone density test and understanding your results

A DEXA scan (dual-energy X-ray absorptiometry) is a quick, painless X-ray that measures how dense your bones are. It takes about 10 to 30 minutes and uses less radiation than a chest X-ray. The scan compares your bone density to that of a healthy 30-year-old and gives you a T-score.

The results fall into three categories. A T-score of -1.0 or higher is normal bone density. A score between -1.0 and -2.5 is osteopenia, meaning your bones are weaker than normal but not yet in the osteoporosis range. A score of -2.5 or lower is osteoporosis, meaning your bones are significantly weakened and fracture risk is high. Your doctor uses your T-score, your age, your sex, and other risk factors (like whether you smoke or take certain medications) to decide whether you need treatment.

The U.S. Preventive Services Task Force recommends bone density screening for all women 65 and older and for men 70 and older. Women between 50 and 64 and men between 50 and 69 should talk to their doctor about whether screening makes sense for them, based on their risk factors. If you have had a fracture from a minor fall, or if osteoporosis runs in your family, screening earlier may be wise.

Medications that slow bone loss or rebuild bone

If exercise and nutrition are not enough, or if your DEXA scan shows osteoporosis, your doctor may recommend medication. The most common type is bisphosphonates (alendronate, risedronate, ibandronate, zoledronic acid), which slow the rate at which your body breaks down old bone. They are taken as a pill once a week or once a month, or as an infusion once a year, depending on which one. They work best when taken on an empty stomach with a full glass of water, and you must stay upright for 30 minutes afterward to avoid irritating your esophagus.

Other options include denosumab (an injection given twice a year), hormone-related therapy (estrogen or raloxifene, mainly for women), and teriparatide (a daily injection that actually rebuilds bone rather than just slowing loss). Your doctor will choose based on your bone density, fracture risk, kidney function, and other medications you take. Bisphosphonates are usually the first choice because they have a long track record and are well-studied in older adults.

All bone medications have side effects and are not right for everyone. Some people cannot take bisphosphonates because of kidney disease or stomach problems. Others worry about rare side effects like jaw problems or unusual fractures. Talk with your doctor about whether the benefits outweigh the risks for you, and ask what to watch for while taking the medication.

Preventing falls and protecting your bones

A strong bone that breaks is only a problem if you fall. In your 60s, preventing falls is as important as building bone density. Falls happen because of poor balance, weak legs, vision problems, medication side effects, and hazards in your home. You can address all of these.

Check your vision. Poor eyesight is a major fall risk. If you wear bifocals or progressive lenses, be careful on stairs — these glasses can distort your view of steps. Ask your eye doctor whether your prescription is right for your daily activities.

Review your medications with your doctor or pharmacist. Some blood pressure medications, sedatives, pain relievers, and other drugs can cause dizziness or balance problems. If you feel unsteady after starting a new medication, tell your doctor before you adjust the dose yourself.

Make your home safer. Remove throw rugs, find electrical cords, install grab bars in the bathroom, improve lighting (especially on stairs and in hallways), and keep frequently used items at waist height so you do not have to reach or bend. Wear shoes with good grip indoors, not socks or slippers.

Build leg strength and balance. Squats, step-ups, and single-leg stands strengthen the muscles that keep you upright. Tai chi and yoga teach your body to recover from a stumble. Even 10 minutes a day makes a difference.

Questions to ask your doctor about bone health

Before your appointment, write down what you want to know. Here are some starting points:

  • Should I have a bone density scan? If so, how often?
  • What is my 10-year fracture risk, based on my age, sex, and health?
  • How much calcium and vitamin D do I need daily, and should I take a supplement?
  • Are there any medications I take that affect bone health?
  • Do I need a bone-building medication, and what are the side effects?
  • What can I do to prevent falls in my home?
  • Should I see a physical therapist to learn safe exercises?

Frequently Asked Questions

Can you rebuild bone density once you lose it?

Partially, yes. Exercise and medication can slow bone loss and rebuild some density, but you cannot return to the density you had at 30. The goal is to keep the bones you have and prevent fractures. Studies show that people who exercise regularly and take vitamin D and calcium can increase bone density by 1 to 3 percent per year, which is meaningful over time.

Is it too late to start exercising if I am already in my 60s?

No. Your bones respond to exercise at any age. People who start strength training and weight-bearing exercise in their 60s, 70s, and beyond see improvements in bone density and, more importantly, in balance and muscle strength that prevent falls. Start slowly and build up gradually to avoid injury.

Do I need a calcium supplement if I eat dairy?

Not necessarily. If you eat three servings of dairy or calcium-rich foods daily, you may get enough. A serving is one cup of milk or yogurt, or 1.5 ounces of cheese. If you do not eat that much, or if you have trouble digesting dairy, a supplement makes up the difference. Your doctor can help you figure out whether you need one.

What is the difference between osteopenia and osteoporosis?

Osteopenia means your bones are weaker than normal but not yet in the fracture-risk range. Osteoporosis means your bones are significantly weakened and fractures are likely from minor falls. Both are measured by DEXA scan. Osteopenia does not always progress to osteoporosis — exercise and good nutrition can stop or slow the decline.

Can I take calcium and vitamin D together?

Yes. Many supplements combine them. Calcium and vitamin D work together — vitamin D helps your body absorb calcium — so taking them at the same time is fine. If you take a separate calcium supplement, take it with food for better absorption.
