Vitamin D: Vital to Bone Health

Vitamin D is vital to bone health and if you don't get enough, you increase your risk of broken bones caused by osteoporosis. Yet despite the essential role of vitamin D in bone health, more than 50% of postmenopausal women with osteoporosis have inadequate levels of vitamin D.

Osteoporosis is a disease of the bones which makes them weak and more likely to break, mostly at the wrist, hip or spine. From the age of 50 onwards, 1 in 3 women and 1 in 5 men will suffer from osteoporosis.

Bone is not static, which means that old bone is constantly breaking down and being renewed. While most people understand the role that calcium plays in this process, many don't realise that calcium intake alone is not enough in order to maintain healthy bones.

Vitamin D plays an important role in ensuring that the body can absorb calcium from food and supplements. In other words, without an adequate intake of vitamin D, your body cannot unlock the benefits of calcium which can put you at risk of osteoporosis. Vitamin D is therefore an essential component of osteoporosis treatment.

  • Postmenopausal women with adequate vitamin D levels had up to 65% greater calcium absorption.
  • Vitamin D reduces the risk of fractures by up to 20%, and fractures of the hip, wrist, forearm or spine by up to 30%.
  • Vitamin D in the presence of calcium works to help reduce bone loss and fracture risk in people with osteoporosis.
  • Vitamin D has been demonstrated to improve muscle strength and reduce body sway, helping to prevent falls in people with, or at risk of, osteoporosis.
