Fatigue. Low Mood. Aches. The Silent Signs of Vitamin D Deficiency.
Author: Tharb Faisl
Do you feel constantly tired, achy, or under the weather — even when you’ve had enough sleep?
You could be low in vitamin D, a crucial nutrient for energy, bone health, and immunity. At Marylebone Diagnostic Centre, we offer a fast, affordable private vitamin D blood test in London, with same-day appointments and results in 24–48 hours.
What Is a Vitamin D Test?
A vitamin D blood test measures your level of 25-hydroxyvitamin D (25-OH D) — the most accurate marker of vitamin D status in the body.
It’s a simple blood draw that takes less than 10 minutes.
Why Should You Get a Private Vitamin D Blood Test?
Low vitamin D levels can impact your:
- Energy levels and overall vitality
- Mood, mental wellbeing & focus
- Muscle and bone strength
- Immunity — especially during flu season
- Pregnancy, fertility, and hormonal balance

Are You at Risk of Deficiency?
You may be more likely to need a private vitamin D blood test if you:
- Spend most of your time indoors or wear sunscreen constantly
- Have darker skin, which lowers natural vitamin D production
- Follow a vegan or vegetarian diet
- Are pregnant, breastfeeding, or over 50
- Experience chronic fatigue, muscle aches, or frequent infections
Symptoms of Vitamin D Deficiency
- Tiredness or constant fatigue
- Muscle weakness or leg cramps
- Bone/joint pain or stiffness
- Low mood, irritability or brain fog
- Frequent colds or slow wound healing
In many cases, symptoms are subtle — or absent. That’s why a vitamin D test in London is a smart first step toward better health.
