Bones are made of living cells and contain collagen and calcium phosphate primarily. Under normal circumstances, bones are as strong as cast iron. They provide support for your body so you can stand upright and walk; they protect vital organs such as your brain, heart, and lungs, and produce white blood cells for your immune system. While osteoporosis is often thought of as a woman’s issue, two million American men currently have osteoporosis, and one in four men will experience a fracture due to thinning bones. In this article, we discuss bone loss and osteoporosis risk in men. Then, we discuss how men can maintain healthy bones as they age.
Bone Loss and Osteoporosis
In most people, bone mass peaks in your 30s ; bones will start to thin after that. When your bones begin to thin, it makes them more fragile and prone to fractures. Loss of bone usually happens slowly over time, and fractures or falls may be the first sign that you have weak bones, or have developed osteoporosis. In addition to being very painful, fractures later in life can become a significant threat to your mobility, independence, and quality of life. Once you have osteoporosis, even minor falls can result in fractures.
By 2020 approximately over 12 million Americans over the age of 50 will develop osteoporosis. According to the International Osteoporosis Foundation, 25% of hip fractures occur in men over the age of 50. Hip fractures, in particular, can be debilitating, and men have a harder time recovering from hip fractures than women. For men over the age of 50, the risk of developing a fracture is 16% higher than the risk of developing prostate cancer.
Male Osteoporosis Risk Factors
Although many believe osteoporosis primarily affects postmenopausal women, many men are also at risk. According to the National Institutes of Health, risk factors for men include:
- Race: White men are at increased risk, but all men can develop osteoporosis.
- Age: The older you are, the higher the risk.
- Genetics: A family history of fractures puts you at higher risk.
- Unhealthy lifestyle: Smoking, excessive alcohol use, low calcium intake, and sedentary way of life all increase the risk of osteoporosis.
- Medications: Regular prolonged use of steroid medications to treat asthma or rheumatoid arthritis called glucocorticoids increase the risk of osteoporosis.
- Low testosterone levels: Certain prostate cancer treatments designed to lower testosterone levels, and undiagnosed low testosterone levels for other reasons increase the risk of osteoporosis.
- Chronic disease: Certain chronic diseases of the lungs, kidneys, stomach, and intestines can limit absorption of calcium or change hormone levels. These issues may result in a higher risk of osteoporosis.
What Can Men Do To Maintain Healthy Bones?
If you have any number of the risk factors outlined above or had a fall or fracture, your bone mineral density can be determined via a DEXA or DXA scan. If the scan shows that you have low bone mineral density, or you are diagnosed with osteoporosis, increasing calcium and vitamin D intake is often recommended to help maintain bone mass.
Calcium for Bone Health
The National Academy of Medicine recommends an intake of 1000 mg of calcium daily for men between the ages of 19-70, while men over 70 need 1200 mg of calcium daily. Table 1 lists foods rich in calcium. When grocery shopping, it’s helpful to read food labels. A good practice is to choose foods that have 10 percent or more of the Daily Value for calcium.
Your body absorbs calcium food sources more efficiently if you eat them at different times throughout the day. Here are some suggestions on how to spread out your calcium intake:
- Make your breakfast oatmeal with milk instead of water
- Have yogurt as a mid-day snack
- Top your baked potato at dinner with steamed broccoli and shredded cheese
- Enjoy calcium-fortified tofu as a plant-based option for dinner
Eating a healthy diet provides many nutrients needed to maintain healthy bones, such as potassium, magnesium, phosphorus, and phytochemicals.

Don’t Forget Vitamin D for Bone Health
Vitamin D is a nutrient that is also needed to maintain strong bones as it helps the body absorb calcium from the foods you eat. The amount of vitamin D you need depends on your age, current vitamin D level, and health status. The current Recommended Dietary Allowance (RDA) is 15 – 20 mcg (600-800 IU) per day, depending on age, and the upper limit for daily intake is 100 mcg (4,000 IU).
Vitamin D rich foods are fatty fish (such as salmon, tuna, and mackerel). Beef liver, cheese, mushrooms, and egg yolks provide small amounts of vitamin D. Some breakfast cereals and milk are often fortified with vitamin D. Drinking one cup of milk gives you about 2.5 mcg (100 IU) of vitamin D.
Your body also makes vitamin D when your skin is exposed to the sun. Make it a goal to go outside every day for a brisk walk (10 to 15 minutes) and expose your unprotected arms or legs to the sun to get some additional vitamin D.
Ultimately, a multipronged approach is recommended for the prevention of bone loss, including participating in regular weight-bearing and resistance exercises, such as walking or running, and weight lifting, eating a well-rounded, balanced, healthy diet, limiting alcohol intake, and avoiding smoking.
