Strong bones, healthy teeth, and proper muscle function all rely on balanced levels of calcium and Vitamin D. Many people in the UK have low Vitamin D due to limited sunlight exposure, and calcium imbalances can go unnoticed until health problems arise. Our Calcium + Vitamin D blood test provides a simple and reliable way to check your levels from the comfort of home.
Calcium is the body’s most abundant mineral, making up a large part of your bones and teeth. It also plays a vital role in:
Muscle contraction
Nerve signalling
Heart rhythm regulation
Blood clotting
Low calcium levels (hypocalcaemia) can cause symptoms such as muscle cramps, tingling, brittle nails, and in the long term, reduced bone strength. High calcium levels (hypercalcaemia) may point to issues with the parathyroid glands, kidneys, or vitamin D metabolism.
Vitamin D helps your body absorb calcium and maintain strong bones. Without enough Vitamin D, even a calcium-rich diet may not be effective. In the UK, deficiency is common—particularly in autumn and winter—leading to fatigue, muscle weakness, bone pain, and increased risk of fractures.
Checking your Vitamin D levels ensures you know whether supplementation or lifestyle changes are needed to protect your long-term health.
This blood test is recommended for anyone who wants to monitor their bone and muscle health, particularly if you:
Have symptoms of Vitamin D deficiency (fatigue, bone pain, frequent infections)
Experience muscle weakness or cramps
Are at risk of osteoporosis or low bone density
Follow a vegan, vegetarian, or dairy-free diet
Spend limited time outdoors or cover your skin when outside
Have a condition affecting calcium metabolism (kidney disease, parathyroid disorders)
Are pregnant, breastfeeding, or over 50 years old
By testing early, you can take action before deficiencies or imbalances impact your quality of life.

Serum Calcium – measures calcium circulating in the blood, helping identify deficiency, excess, or underlying metabolic conditions.
25-hydroxy Vitamin D (25(OH)D) – the most accurate marker of Vitamin D status, showing whether your levels are sufficient, insufficient, or deficient.
Normal levels – reassurance that your calcium and Vitamin D intake and metabolism are balanced.
Low calcium or Vitamin D – may suggest dietary insufficiency, lack of sunlight exposure, or absorption issues.
High calcium – could indicate parathyroid gland problems, kidney issues, or excessive supplementation.
If your results are outside the healthy range, follow-up with a GP is advised.
