Key takeaways:
Your bone density peaks once you hit age 30 and starts to decline at age 50.
You can prevent bone loss and even build bone density by doing strength training and weight-bearing exercises at least three to four times a week.
Eat a healthy diet stocked with bone-building foods that are high in calcium, vitamin D, and protein. Avoid smoking and excessive alcohol use.
As you age, it's important to prioritize keeping your bones and joints healthy. Increasing your bone density can significantly decrease your risk of falls and fractures, which is critical once you reach your 60s.
Some factors that have an impact on bone density are beyond your control, such as genetics and hormonal changes, including menopause. However, there are several lifestyle factors that you can control, such as your diet and exercise routine. Improving your bone density by just 10 percent could cut your risk of fractures in half.
During childhood and early adulthood, your bones continue to develop and gain strength. By the time you hit age 30, they reach their maximum bone mass and are at their strongest point. Your bone density stays relatively stable until you reach age 50. At this time, you start to lose bone faster than it is formed or rebuilt.
The time frame for when bone mass loss (also called osteopenia) occurs is different for men and women. For women, bone loss occurs more rapidly during menopause (around age 50 through 54) before it levels off. This is due to declining estrogen levels. Women can lose up to 20% of bone mass during perimenopause and menopause. Bone mass stabilizes after menopause, but at around age 70, bone loss resumes.
For men, bone loss peaks at age 65, and the decline continues. Both men and women can lose 25% of their bone mass after age 50 if steps aren’t taken to slow it down. If bone mass loss progresses, it can lead to osteoporosis, a condition that results in reduced bone mineral density and a higher chance of fractures.
There are several risk factors or conditions that make you more predisposed to losing bone density, according to the International Osteoporosis Foundation (IOF). These include:
Early menopause, especially before age 40
Family history of osteoporosis
Overactive thyroid
Chronic lung disease
Crohn’s disease
Celiac disease
Rheumatoid arthritis
Certain medications, including prednisone, cortisone, and anti-seizure drugs
Low body weight
Cigarette smoking and alcohol abuse
Low levels of vitamin D, calcium, protein, or potassium
Inactivity
Taking steps now with lifestyle, diet, and exercise changes can help prevent further bone loss — and, in some cases, even build up bone density. If you don’t take those healthy steps, experts say it can put you at risk of osteoporosis, falls, and fractures. This can limit your ability to live independently as you get older. Osteoporosis can cause symptoms including back pain, stooped posture, and even loss of height.
Roughly 50% of women over the age of 50 will break a bone due to osteoporosis. There are ways you can avoid being part of the statistic. Having some bone density loss as you age is inevitable, but you can make changes to maintain what you have and prevent osteoporosis. There are also ways you can increase bone density once you are 60 or older. The sooner you start, however, the better.
Calcium is the main mineral that keeps your bones strong and helps maintain bone density. Eating a healthy diet that contains calcium-rich foods is important. The Recommended Dietary Allowance (RDA) in the U.S. is 1,000 mg for those younger than 51 and 1,200 mg for women age 51 and older. Men should bump their calcium to 1,200 mg once they hit age 70.
The best way to get enough calcium is through eating calcium-rich foods. Calcium in your diet is preferred to taking a supplement. But if you can’t get enough calcium through food, talk with your primary care provider about a calcium supplement.
Focus on eating foods high in calcium, including:
Dairy products such as yogurt, milk, and cheese
Leafy vegetables, including kale and broccoli
Tofu
Nuts, such as almonds and hazelnuts
Fish, including sardines and salmon
Grains
Fortified orange juice
But talk to your primary care provider about the best sources of calcium for you.
Vitamin D keeps your bones strong as it helps your body absorb the calcium you eat. You can get vitamin D through food, such as salmon, egg yolks, or fortified milk. However, it can be difficult to get the recommended amount through diet alone, so you should also consider taking a supplement. The National Osteoporosis Foundation recommends that adults over 50 get between 800 and 1,000 IU of vitamin D every day.
Exposing your skin to sunlight for short periods is another way to boost levels of this important vitamin. Your liver and kidneys make vitamin D when the sun hits your skin. Experts say all it takes is sitting outside for 5 to 30 minutes without sunscreen for your body to make vitamin D.
Between your diet, supplements, and short daily exposure to sunlight, you should get enough vitamin D to strengthen your bones.
Vitamin K2 can help, too. It may keep your bones strong by helping your body metabolize calcium. Research suggests calcium, vitamin K2, and vitamin D may work together to increase bone mineral density. Animal products and fermented foods –– such as chicken breast and fermented soybeans –– are good sources of vitamin K2.
Eating enough protein is another way that you can keep your bones strong. Protein helps your body absorb calcium and helps with bone formation. A 2023 study found that those who had a higher protein intake had a higher total body bone density. An interesting note: The study found that this positive result was only seen in those eating animal protein; those eating plant protein had a lower bone density.
Eating enough protein can help prevent fractures, as well. A large 2014 study looking at over 144,000 postmenopausal women found that those who ate more protein had less chance of forearm fractures, as well as higher bone density overall.
Add more protein to your diet by eating foods such as meats, eggs, seafood, nuts, or seeds. You can also use protein powder in smoothies or drinks.
Exercise is a critical part of keeping your bones strong. It may increase bone mineral density in men and women as they age. For example, a Cochrane Library Review found that exercise not only prevented fractures in postmenopausal women but also increased bone density. Those who exercised had 3.2% less bone loss in their spine and 1.03% less bone loss in their hips compared with those who didn’t exercise.
A 2018 study found that two types of exercises helped increase bone density: weight-bearing and strength or resistance exercises. Both can help strengthen your bones and muscles and prevent or manage osteoporosis.
According to the IOF, you should try to do 30 to 40 minutes of exercise at least 3 to 4 times a week. Here’s how to add weight-bearing and strength-training moves to your exercise routine for strong bones.
Weight-bearing exercises challenge you to move against gravity while standing. For these exercises to build up bone density, researchers say they have to be fairly high-impact. Walking doesn’t create enough ground force to build up bone strength. Even so, walking has many other benefits and is recommended for overall health.
For bone-building benefits, you should also include exercises such as:
Dancing
Tennis or pickleball
High-impact aerobics, such as jogging, jumping rope, and plyometric exercises
Tai chi or yoga
If you have osteoporosis, you may need to avoid high-impact exercises. Talk to your doctor about the best exercises for you.
Exercises that build strength using resistance –– from free weights, machines, resistance bands or your body weight –– also increase bone density. For best results, studies have found that you should do resistance exercise three times a week. Work toward doing 8 to 10 exercise repetitions for 2 to 3 sets. Examples of resistance exercises that may build bone density include:
Weighted squats
Leg presses
Hamstring curls
Stair-climbing
Step boxes with weighted vests
Power cleans with weighted vests
Latissimus pull-downs
Seated rowing
If you have osteoporosis, use caution with twisting motions, bending at the waist, or doing sit-ups. You can talk to your primary care provider about suitable resistance exercises.
Maintaining a healthy weight –– which will be different for everyone –– is important as you get older. Being overweight negatively affects your health; however, being underweight can cause bone loss and a higher risk of fractures. If you are underweight, talk to your doctor about how to gain weight healthily. If you are overweight, it is important for your health that you lose weight, but it’s also important that you exercise. A 2015 study found that doing weight-bearing and resistance exercises helps prevent and maintain bone strength while losing weight.
Smoking and excessive drinking affect bone health. Smoking causes a significantly increased risk of fractures. If you do smoke, talk to your doctor for help quitting.
Excessive alcohol use increases fracture risk, decreases bone strength, and increases the risk of falls, according to a study in Osteoporosis International. Alcohol in moderation, which is defined as two glasses of wine per day, does not affect bone health, according to the IOF.
If you are at high risk of bone loss or fracture, your doctor may talk to you about osteoporosis medications to prevent bone loss and increase bone strength. Drug therapies may include raloxifene, bisphosphonates, bazedoxifene, or denosumab.
Hormone replacement therapy (HRT) for menopausal symptoms has several benefits, as it can help lower fracture risk and increase bone density in postmenopausal women. However, it does have some risks. Talk to your doctor to see if it is right for you.
Your bones reach their peak strength at age 30 and start to decline once you hit your 50s. For women going through menopause, it is especially important to focus on maintaining and building your bone strength, because you are at more risk for fractures. There are some things you can’t control, such as genetics and menopause. However, making lifestyle changes can help increase bone density after age 60.
Exercise regularly, focusing on strength training and weight-bearing exercises. Maintain a healthy weight, and make sure your diet has plenty of calcium, vitamin D, and protein. Get a little sunshine every day, and avoid smoking and excessive alcohol use. You can also talk to your doctor about medications to help preserve bone density.
