Frequently asked questions
Can a blood test detect osteoporosis?
Can a blood test detect osteoporosis?
Blood tests cannot directly measure bone density, which requires a DEXA scan. However, they identify underlying drivers of bone loss including vitamin D deficiency, elevated parathyroid hormone, calcium imbalances, and bone turnover markers. Addressing these early can significantly slow bone loss.
How does vitamin D affect bone health?
How does vitamin D affect bone health?
Vitamin D is essential for calcium absorption in the intestine. Without adequate vitamin D, even a calcium-rich diet results in poor calcium uptake, forcing the body to draw calcium from bones. Chronic vitamin D deficiency accelerates bone resorption and increases fracture risk.
Who is most at risk of poor bone health?
Who is most at risk of poor bone health?
Postmenopausal women experience the most rapid bone loss due to the withdrawal of oestrogen. Other high-risk groups include men over 70, people on long-term corticosteroids, those with coeliac disease or other malabsorption conditions, and anyone with a history of fragility fractures.
What nutrients are most important for bone health beyond calcium?
What nutrients are most important for bone health beyond calcium?
Vitamin D, magnesium, vitamin K2, and phosphate all play critical supporting roles. Vitamin K2 directs calcium into bones rather than arteries. Magnesium is involved in vitamin D activation and osteoblast function. A comprehensive bone health panel measures all of these.
