Bone Health Knowledge Hub

Bone density refers to the amount of mineral content in a given volume of bone, measured by imaging tests. Bone strength, however, encompasses not only density but also bone quality, architecture, and the integrity of the bone matrix. A bone can have good density but poor quality if collagen and other structural proteins are compromised. Both factors are essential for fracture resistance and overall skeletal health.

The recommended dietary allowance (RDA) for calcium is 1,000 mg per day for adult men aged 19 to 70 years, and 1,200 mg per day for men over 70. These recommendations are established by major health organisations based on research demonstrating the amounts needed to maintain bone health and support other physiological functions. Individual needs may vary based on dietary patterns, absorption efficiency, and other factors, so consulting our nutrition guide and personalised strategies is beneficial.

Exercise is a powerful stimulus for bone formation and can significantly improve bone density, particularly resistance and weight-bearing activities. However, exercise works most effectively when combined with adequate nutrition. Without sufficient calcium, vitamin D, protein, and other essential nutrients, even rigorous training will not optimise bone health outcomes. The most effective approach combines both nutritional strategies and regular physical activity tailored to your age and current fitness level.

Whole foods provide nutrients in their natural context, alongside beneficial compounds like fibre, polyphenols, and other bioactive substances that work synergistically. Supplements can be valuable for filling specific gaps or when food sources are insufficient, but they should not replace a nutrient-dense diet. The most effective strategy typically involves optimising dietary intake first, then using targeted supplements where needed based on individual assessment and needs. Our guides explore both approaches in detail.

Assessment begins with understanding your personal risk factors, including age, family history, lifestyle habits, and current nutritional patterns. Imaging tests such as dual-energy X-ray absorptiometry (DXA) scanning provide objective measurements of bone density. Healthcare providers can recommend appropriate testing based on your individual circumstances. Our comprehensive guides walk you through understanding these assessments and what they mean for your specific situation and goals.
