    Bone health refers to the strength of bones and the quality of bone structure. Bone health is usually measured as bone mineral density. Bone health is affected by nutrient intake, hormonal regulation, exercise, and age, among other factors.

    Bone Health falls under the Joints & Bones category.

    What is bone health?

    Bones are dynamic, specialized connective tissue that play an integral role in maintaining the proper functioning of the body. Healthy bones are strong and dense, and play the following essential roles in the body:

    • providing support for body structure and muscle attachment, allowing us to move and exercise freely
    • protecting vital organs
    • housing bone marrow, where blood and bone cells are formed
    • participating in hormonal homeostasis
    • serving as a storage depot for minerals like calcium and phosphorus

    Given this remarkable range of responsibilities, bone health is multifaceted and inextricably linked to other organ systems (e.g., muscular, endocrine, and gastrointestinal).

    What determines bone health?

    How is bone health measured?

    Bone health is first assessed by a medical provider through a detailed history and physical exam, which may include validated risk factor screening tools for bone-related issues. Findings from this assessment dictate whether and how bone health will be measured. Bone mineral density (BMD) is the most common way to measure someone’s bone health.

    What are some common ways to measure bone health?

    How does physical activity affect bone health?

    An appropriate and well-designed exercise program is an excellent way to preserve and improve bone health. Not only does exercise increase BMD, but it also protects against falls/injuries through enhanced muscle strength, balance, and coordination. The exercises that are most beneficial for bone health vary somewhat depending on one’s age and comorbidities, but resistance training (like weight lifting),[1] plyometrics (like bodyweight jumps),[2] weight-bearing exercises (like running and stair climbing),[3] and activities that promote multidirectional loading of bone tissue (like playing sports)[4] are all effective for promoting bone health. Resistance training may be especially important for postmenopausal individuals and older adults who are at higher risk of osteoporosis.[1][5]

    It is important to note that too much exercise may be detrimental to bone health. Excessive exercise without adequate recovery and nutrition may result in a condition known as relative energy deficiency in sport (RED-S), which is characterized by decreased bone mass.[6]

    What are some types of exercise that can improve bone health?

    Have any supplements been studied for bone health?

    Calcium and vitamin D have been extensively studied for their effect on bone health in a variety of populations. Although a diet that contains adequate calcium and vitamin D is important for bone health, there is little evidence that calcium supplements — administered with or without vitamin D — reduce the risk of fractures.[7] However, calcium and/or vitamin D supplementation may confer a small benefit to BMD and reduce fracture risk in two groups of people: those with extremely low baseline levels of calcium or vitamin D, and older adults who are at an increased risk of osteoporosis.[8]

    Other supplements that may affect bone health can be found in the Examine Database for bone health, below.

    How can diet affect bone health?

    A well-balanced diet that matches a person’s energy needs is important for bone health. Three nutrients that are particularly vital for bones are calcium, vitamin D, and protein. These nutrients contribute to establishing peak bone mass in childhood, and, in adults, they maintain bone mass and prevent bone loss with age. Low-protein diets are associated with reduced bone mass and fracture risk in older adults.[9] A lack of vitamin D and calcium can cause soft, weak bones in children, a condition known as rickets. In adults, this condition is known as osteomalacia.[10]

    Other beneficial nutrients for bone health include copper, zinc, fluoride, magnesium, phosphorus, vitamin C, vitamin K, and omega-3 fatty acids.[11][12] Diets that contain fruits and vegetables (e.g., the Mediterranean diet), dairy products, seafood, and a low intake of alcohol, caffeine, and sodium are all associated with better bone health.[11]

    The best diet for bone health also depends on a person’s pre-existing medical conditions. For example, a gluten-free diet may improve bone mass in people with celiac disease.[13]

    What is the link between gut health and bone health?

    Which other factors can affect bone health?

    Having underweight, smoking cigarettes, being a woman, being of white or Asian descent, having a family history of osteoporosis, and long-term use of certain medications (including corticosteroids, breast cancer treatments, selective serotonin reuptake inhibitors (SSRIs), and proton pump inhibitors) are risk factors for poor bone health.[14][15]

    Certain diseases may elevate the risk for poor bone health. These include anorexia, cancer, type 2 diabetes, inflammatory bowel disease, liver or kidney disease, multiple sclerosis, thyroid disorders, lupus, alcohol use disorder, Cushing’s disease, and rheumatoid arthritis.[16]

    Frequently asked questions

    What is bone health?

    Bones are dynamic, specialized connective tissue that play an integral role in maintaining the proper functioning of the body. Healthy bones are strong and dense, and play the following essential roles in the body:

    • providing support for body structure and muscle attachment, allowing us to move and exercise freely
    • protecting vital organs
    • housing bone marrow, where blood and bone cells are formed
    • participating in hormonal homeostasis
    • serving as a storage depot for minerals like calcium and phosphorus

    Given this remarkable range of responsibilities, bone health is multifaceted and inextricably linked to other organ systems (e.g., muscular, endocrine, and gastrointestinal).

    What determines bone health?

    Bone health is determined by genetics and the environment. Throughout life, both internal (e.g., genetics and hormones) and external (e.g., exercise and diet) factors are continually modeling and remodeling bones. The remodeling occurs via a complex and carefully orchestrated interplay between bone resorption (bone breakdown) and bone deposition (bone formation). Bone mass, i. e., the amount of minerals in the bone, reflects the interplay between these two processes.

    Most bone mass is accrued early in life, with peak bone mass achieved by the age of 30. In later life, bone remodeling continues, but more bone is generally lost than gained. However, this doesn’t mean bone health can’t improve at any age. In fact, it is estimated that most of the adult skeleton is replaced every ten years, and lifestyle choices can modify the strength and health of these “new” bones.

    How is bone health measured?

    Bone health is first assessed by a medical provider through a detailed history and physical exam, which may include validated risk factor screening tools for bone-related issues. Findings from this assessment dictate whether and how bone health will be measured. Bone mineral density (BMD) is the most common way to measure someone’s bone health.

    What are some common ways to measure bone health?

    One common measurement of bone health is a BMD test.[17] A BMD test measures bone density in the hip and lumbar spine. It is used to diagnose osteoporosis, predict fracture risk, and monitor therapeutic outcomes. The results of a BMD test are provided as a T-score, which compares your BMD to established norms for your sex, age, and other demographic information. Results of a BMD test are presented as “normal”, “low bone mass”, “osteoporosis”, and “severe or established osteoporosis”.

    Other measures that may be used to assess bone health include imaging (e.g., X-rays), genetic testing, and blood tests for hormones (e.g., growth hormone, parathyroid hormone, calcitonin, cortisol, and sex hormones); markers of bone turnover (e.g., C-telopeptide crosslink, bone-specific alkaline phosphatase, and amino-terminal propeptide of type I procollagen); and certain nutrients (e.g., vitamin D and calcium).

    How does physical activity affect bone health?

    An appropriate and well-designed exercise program is an excellent way to preserve and improve bone health. Not only does exercise increase BMD, but it also protects against falls/injuries through enhanced muscle strength, balance, and coordination. The exercises that are most beneficial for bone health vary somewhat depending on one’s age and comorbidities, but resistance training (like weight lifting),[1] plyometrics (like bodyweight jumps),[2] weight-bearing exercises (like running and stair climbing),[3] and activities that promote multidirectional loading of bone tissue (like playing sports)[4] are all effective for promoting bone health. Resistance training may be especially important for postmenopausal individuals and older adults who are at higher risk of osteoporosis.[1][5]

    It is important to note that too much exercise may be detrimental to bone health. Excessive exercise without adequate recovery and nutrition may result in a condition known as relative energy deficiency in sport (RED-S), which is characterized by decreased bone mass.[6]

    What are some types of exercise that can improve bone health?

    To improve bone strength, exercise should be dynamic, induce a high strain on the bone, and be applied rapidly in multiple directions. One way to achieve this is through progressive, high-load resistance training.[18] For the best effects, it’s important to utilize a heavy load (80%–85% of your maximal strength), perform training at least twice per week, and involve major muscle groups. High-impact, high-load exercises, such as jumping, bounding, skipping, drop jumps, and (to some extent) running, are also effective for stimulating bone. Incorporating these exercises 4–7 times per week at a dose of 10–50 “impacts” per day appears to be optimal.[19] Combining high-impact exercise with vitamin D and calcium or progressive resistance training can lead to further improvements in bone health.

    Walking is often recommended as a way to maintain bone health. However, some meta-analyses suggest that walking has minimal to no effects on BMD, likely because the impact isn’t high enough.[20][21] In addition, prolonged endurance exercises like swimming, and cycling — while beneficial for cardiovascular health — provide very little osteogenic (bone-forming) activity.[22]

    Have any supplements been studied for bone health?

    Calcium and vitamin D have been extensively studied for their effect on bone health in a variety of populations. Although a diet that contains adequate calcium and vitamin D is important for bone health, there is little evidence that calcium supplements — administered with or without vitamin D — reduce the risk of fractures.[7] However, calcium and/or vitamin D supplementation may confer a small benefit to BMD and reduce fracture risk in two groups of people: those with extremely low baseline levels of calcium or vitamin D, and older adults who are at an increased risk of osteoporosis.[8]

    The best diet for bone health also depends on a person’s pre-existing medical conditions. For example, a gluten-free diet may improve bone mass in people with celiac disease.[13]

    What is the link between gut health and bone health?

    The relationship between gut health and bone health — known as the gut-bone axis — is an emerging area of research.[25] There are a number of potential ways in which the two may be connected. For one, gut dysbiosis impairs the absorption of calcium in the intestines. Additionally, several gut-derived metabolites exert control over cells that are responsible for bone turnover. Finally, gut-dysbiosis-induced intestinal permeability causes the release of inflammatory cytokines into the bloodstream, which can negatively affect BMD and other bone-health-related factors.

    Prebiotics and probiotics have been investigated for their ability to improve bone health via their effects on the gut microbiome. While more research is needed, some evidence suggests that probiotic supplementation may protect against the loss of BMD and improve markers of bone turnover in postmenopausal women.[25]

    Modulation of the gut microbiota through other means, such as diet, synbiotics, postbiotics, antibiotics, and fecal microbiota transplantation, is another avenue through which the gut-bone axis can be targeted to improve bone health. The Mediterranean diet may exert favorable effects on reducing fracture risk due to its high content of fiber, fermented dairy, and polyphenols, which favorably alter the composition of the gut microbiome.[26]

    Which other factors can affect bone health?

    Having underweight, smoking cigarettes, being a woman, being of white or Asian descent, having a family history of osteoporosis, and long-term use of certain medications (including corticosteroids, breast cancer treatments, selective serotonin reuptake inhibitors (SSRIs), and proton pump inhibitors) are risk factors for poor bone health.[14][15]

    Certain diseases may elevate the risk for poor bone health. These include anorexia, cancer, type 2 diabetes, inflammatory bowel disease, liver or kidney disease, multiple sclerosis, thyroid disorders, lupus, alcohol use disorder, Cushing’s disease, and rheumatoid arthritis.[16]

    How does aging affect bone health?

    In most people, bone health declines in later life. This includes a decrease in BMD (usually beginning in the early 40s for men and late 30s for women); an increased risk of osteoporosis, bone fractures, and certain bone cancers; and a higher prevalence of degenerative bone/joint conditions (such as osteoarthritis). Among these age-related concerns, the increased risk of osteoporosis is the most common cause of bone disease in older adults.

    This is because approximately 90% of our bone mass is acquired between birth and 20 years of age.[23] Peak bone mass is maintained in men until their early 40s, and in women until their late 30s, at which point BMD begins to decline. The decline begins earlier in women due to the hormonal changes that occur during perimenopause and menopause, especially the decline in estrogen.[24] After age 60, the rate of BMD loss in both men and women is around 1%–1.5% each year, and, by age 70, around 30%–40% of total bone mass is lost.[24] People who achieve a higher peak bone mass early in life are at a significantly reduced risk of osteoporosis. While bone mass is influenced by genetics, diet and physical activity can also help build more bone during childhood and attenuate the decline that begins around midlife.
