You’ve had a Vitamin D blood test, but what do the numbers actually mean? At Pharmacyexprezz, we often see patients confused by their results. This guide explains everything in simple terms so you can understand your Vitamin D levels and what to do next.
What Does the Vitamin D Test Measure?
The test measures 25-hydroxy vitamin D — the main form of Vitamin D stored in your blood. It shows how much Vitamin D your body has available to use.
Vitamin D Blood Test Result Ranges
Here’s what your result typically means:
- Severe Deficiency: Below 25 nmol/L
- Deficiency: 25 – 49 nmol/L
- Insufficient: 50 – 74 nmol/L
- Sufficient (Normal): 75 – 150 nmol/L
- High: Above 150 nmol/L (rare, usually from excessive supplements)
Most experts recommend keeping your levels above 75 nmol/L for optimal health.
What Do Low Vitamin D Levels Mean?
If your result is low, you may experience:
- Constant tiredness and fatigue
- Muscle aches and weakness
- Bone or joint pain
- Frequent colds or infections
- Low mood or depression
- Slow healing of wounds
What Should You Do Next?
If your levels are low or insufficient:
- Book an appointment at Pharmacyexprezz

If your levels are normal:
