Private Vitamin D Test in London – Are You Deficient Without Knowing It?
By Tharb Faisl
The Silent Epidemic – Why Vitamin D Deficiency Is So Common, Vitamin D plays a vital role in your bone health, immune system, energy levels, and even your mood. Yet in Central London, due to limited sunlight and busy indoor lifestyles, thousands of people walk around deficient without realising.
A Vitamin D blood test is the only way to know for sure — and at Marylebone Diagnostic Centre, we make it fast, affordable, and accurate.

Do These Symptoms Sound Familiar?
You may be deficient if you experience:

- Muscle weakness, cramps, or bone pain
- Feeling low or depressed (especially in winter)
- Frequent colds or infections
- Hair loss or brittle nails
- Poor sleep quality
- Difficulty focusing or ‘brain fog’

Who’s Most at Risk?
Here’s a quick look at the groups most likely to suffer from low Vitamin D in the UK:
Indoor workers, people with darker skin tones, and the elderly are especially vulnerable — particularly in cities like London where sunlight is scarce during most of the year.
What Does a Vitamin D Test Involve?
At Marylebone Diagnostic Centre, our Vitamin D test measures 25-hydroxyvitamin D (25-OH D) — the most accurate way to assess your body’s vitamin D stores.
| What We Test | What It Tells You |
| Vitamin D2 + D3 Total | Reflects your overall Vitamin D status |
| 25(OH)D level | Helps determine if you’re deficient, insufficient, or optimal |
| Optional Add-Ons | Calcium, Magnesium, and Bone Health markers |
