The strength of bones is often described by bone mineral density (BMD), which reflects how much mineral content is present within bone tissue.
Specialised cells called osteoblasts help build new bone by producing a collagen framework. Minerals such as calcium and phosphorus are then deposited into this framework, helping bones maintain their structure and strength.
Nutrients such as calcium, vitamin D3 and vitamin K2 are often discussed for the roles they play in supporting this process.


Vitamin D3 plays an important role in how the body manages calcium. It helps the body absorb calcium from food through the digestive system and supports normal calcium levels in the bloodstream.
When vitamin D levels are low, the body may not absorb calcium as efficiently. Maintaining adequate vitamin D levels is therefore considered an important factor in supporting overall bone health.


Vitamin K2 is often discussed alongside vitamin D3 because of its role in supporting how calcium is used in the body.
Research suggests vitamin K2 helps activate certain proteins involved in bone metabolism. These proteins help guide calcium into bone tissue, where it contributes to normal bone structure.


Bone health can be influenced by a range of factors, including ageing, physical activity levels and hormonal changes such as those that occur during menopause.
Maintaining a balanced diet that includes key nutrients such as calcium, vitamin D and vitamin K, along with regular weight-bearing activity, helps support healthy bones throughout life.
