The Great British Bone Check: Why Vitamin D and Calcium Testing Matters
By Dr Lauren Holland | Marylebone Diagnostic Centre, London
As winter approaches and sunlight fades, millions across the UK experience low vitamin D levels – a hidden cause of fatigue, bone pain, and muscle weakness.
It’s no coincidence that osteoporosis and vitamin D deficiency are rising nationwide, prompting many experts to call for what’s being dubbed “The Great British Bone Check.”
At Marylebone Diagnostic Centre (MDC), we support this movement by offering fast, accurate testing that helps you understand your bone strength and vitamin balance before problems arise.
Why Vitamin D and Calcium Matter
Your bones are living tissue, constantly regenerating. Vitamin D helps your body absorb calcium – the mineral that gives bones their strength.
When either is low, bones gradually weaken, increasing the risk of:
- Osteoporosis and fractures
- Chronic back or joint pain
- Fatigue and muscle cramps
- Slow healing and low immunity
Without testing, many people never realise their levels are suboptimal until a fracture or persistent pain reveals the problem.
Who Needs a Bone Health Check?
You may benefit from testing if you:
- Spend little time in sunlight or work indoors
- Follow a vegan or low-dairy diet
- Are post-menopausal or over 50
- Take long-term medication (e.g. steroids, anticonvulsants)
- Have chronic fatigue, weakness, or bone/joint aches
The Bone Health Profile at MDC
At Marylebone Diagnostic Centre, we provide a simple yet comprehensive Vitamin D & Bone Health Blood Test, analysing the key nutrients that influence bone metabolism.
Vitamin D (25-Hydroxy-Vitamin D)
Measures your body’s active vitamin D level – essential for calcium absorption and immune function.
Calcium & Phosphate
Evaluates bone mineralisation and parathyroid activity.
Magnesium
Supports bone density and prevents muscle cramps.
Parathyroid Hormone (PTH)
Assesses hormonal regulation of calcium – crucial in diagnosing early bone weakness.
All tests are performed under our QC-validated laboratory system, ensuring precision that meets the Marylebone High Standard.
Why Testing Is Better Than Guessing
Supplements help only if you know what your body truly needs.
Too much calcium without enough vitamin D can lead to kidney strain or calcification; too little may cause brittle bones.
Testing allows personalised, safe, and effective correction.
