What You Can Do to Lower Your Risk
You cannot prevent osteoporosis entirely, but you can slow bone loss significantly through choices you make now. The three things that matter most are getting enough calcium and vitamin D, doing weight-bearing exercise, and avoiding habits that weaken bones. Starting these habits in your 50s and 60s is still worthwhile — bone density can improve at any age, though the gains are larger the earlier you begin.
Your bones are living tissue that breaks down and rebuilds constantly. When you lose bone faster than your body replaces it, your bones become thinner and more fragile. The goal is to tip that balance the other way: give your body the raw materials it needs and the stimulus to use them.
Key Takeaways
- Calcium and vitamin D work together — your body cannot absorb calcium without enough vitamin D, so both matter equally.
- Weight-bearing exercise like walking, dancing, or climbing stairs signals your bones to stay dense; swimming and cycling do not provide this signal.
- Smoking and heavy alcohol use speed up bone loss, and quitting or cutting back will slow that loss within months.
- A bone density test (DEXA scan) shows whether your bones are thinning and helps your doctor decide whether medication would help.
Getting Enough Calcium and Vitamin D
Adults over 50 need 1,000 to 1,200 mg of calcium per day and 800 to 1,000 IU of vitamin D per day. Food is the best source if you can manage it. Dairy products — milk, yogurt, cheese — contain both calcium and vitamin D (if fortified). Leafy greens like kale and collards, canned fish with bones, and fortified plant-based milks also count.
If you cannot get enough from 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 — your body absorbs only what it can use in one sitting. Vitamin D supplements are easier: one dose per day works fine. Ask your doctor what dose makes sense for you, especially if you have kidney disease or take certain medications that affect how your body uses these nutrients.
Caffeine and salt can increase calcium loss through urine, but only in large amounts. A cup or two of coffee daily is not a problem. Very high sodium intake — more than what most people eat without thinking about it — does matter, so if you are watching your salt for blood pressure reasons, your bones benefit too.
Exercise That Strengthens Bones
Weight-bearing exercise is the kind where your bones support your body weight against gravity. Walking, dancing, hiking, stair climbing, and jogging all count. These activities create tiny stress on your bones that triggers them to rebuild stronger. Swimming and cycling are excellent for your heart and muscles, but they do not provide this bone-building signal because the water or seat supports your weight.
Aim for at least 150 minutes of moderate activity per week — that is 30 minutes five days a week, or three 50-minute sessions. You do not have to do it all at once. Three 10-minute walks spread through the day works. If you are not active now, start slowly: 10 minutes of walking most days, then add a few minutes each week.
Strength training also helps, especially exercises that work your hips and spine — the places where fractures hurt most. You do not need a gym. Bodyweight exercises like wall push-ups, step-ups, or standing on one leg while brushing your teeth all work. If you have balance problems or a history of falls, ask your doctor or a physical therapist what is safe for you before starting.
Habits That Speed Up Bone Loss
Smoking accelerates bone loss at any age. The good news: bone loss slows within months of quitting, and the longer you stay smoke-free, the more your bone density recovers. It is never too late to see a benefit.
Heavy alcohol use — more than one drink per day for women or two for men — interferes with calcium absorption and damages bone-building cells. If you drink more than that, cutting back will help your bones. You do not have to quit entirely unless your doctor recommends it.
Some medications increase bone loss, including long-term corticosteroids (like prednisone for asthma or rheumatoid arthritis) and certain seizure medications. If you take these regularly, tell your doctor — they may recommend a bone density test sooner than usual, or suggest a medication to protect your bones.
When to Get a Bone Density Test
A DEXA scan (dual-energy X-ray absorptiometry) measures how dense your bones are and compares them to healthy young bone. It is painless, takes about 10 minutes, and uses less radiation than a chest X-ray. The results tell you whether your bones are normal, show early thinning (osteopenia), or have osteoporosis.
Current guidelines recommend a DEXA scan for all women at age 65 and all men at age 70, even if you have no symptoms. If you are younger but have risk factors — a family history of osteoporosis, a previous fracture, or long-term use of corticosteroids — ask your doctor whether testing makes sense for you now. The test helps your doctor decide whether the steps you are taking are enough or whether medication would help.
If your first scan shows normal bones, you usually do not need another for 10 years. If it shows thinning, your doctor may repeat it every one to two years to see whether your changes are working or whether medication would help.
Preventing Falls When Your Bones Are Fragile
Even strong bones can fracture from a bad fall. If you have been told your bones are thinning, fall prevention becomes as important as bone-building. Remove tripping hazards — loose rugs, clutter on stairs, cords across walkways. Make sure your home is well-lit, especially at night and on stairs. Install grab bars in the bathroom and consider a shower chair if balance is shaky.
Vision and balance problems increase fall risk. If you have had a fall or feel unsteady, ask your doctor for a balance assessment. Physical therapy can improve balance and strength. Certain medications — sedatives, blood pressure drugs, pain relievers — can make you dizzy; your doctor can review whether any of yours are contributing.
Wear shoes with good grip and support, not socks or slippers on hard floors. If you use a cane or walker, use it every time, not just when you feel bad — the goal is to prevent the fall that would happen if you did not have it.
What to Ask Your Doctor
Before your next visit, write down these questions so you do not forget them:
- Should I have a bone density test, and if so, when?
- How much calcium and vitamin D do I need, and should I take a supplement?
- Are any of my medications affecting my bone health?
- What type of exercise is safe for me, and should I see a physical therapist?
- If my test shows thinning bones, would medication help, or should I focus on diet and exercise first?
Frequently Asked Questions
Can I reverse osteoporosis with diet and exercise alone?
Diet and exercise slow bone loss and can improve bone density, but they work best when started before bones become very thin. If a DEXA scan shows osteoporosis (not just early thinning), your doctor may recommend medication alongside these habits. Medication plus exercise and calcium works better than either one alone.
Is it too late to start if I am already 70 or 80?
No. Bone responds to exercise and good nutrition at any age, though the gains are smaller than they would be at 50. Even a small increase in bone density or strength can mean the difference between a fracture and a fall you walk away from. Starting now is better than waiting.
Do I need to take calcium supplements if I eat dairy?
Not necessarily. If you eat three servings of dairy or fortified plant-based milk daily, plus other calcium sources like leafy greens or canned fish, you may reach your target without supplements. A food diary for a few days can show you whether you are getting enough. If not, a supplement fills the gap.
What if I cannot do weight-bearing exercise because of arthritis or balance problems?
Talk to your doctor or a physical therapist about what is safe. Water aerobics, tai chi, and gentle strength training can help even when walking hurts. The goal is to do something that challenges your muscles and bones without causing pain or falls.
How long does it take to see results from diet and exercise changes?
Bone density changes slowly — usually 6 to 12 months before a DEXA scan would show improvement. But you will likely notice other benefits sooner: more energy, better balance, and stronger muscles within weeks. These changes reduce fall risk even before bone density improves.
