Details about Vitamin Profile
What is the Vitamin Profile test?
The Vitamin Profile is a focused blood test that measures Vitamin D, Vitamin B12, and Folate, three of the most commonly deficient and clinically important vitamins. Together, these nutrients play a central role in bone health, immune function, neurological health, and red blood cell formation.
This profile is often used as a first-line nutritional screen, particularly when symptoms are non-specific. It provides a balanced overview without the need for extensive micronutrient testing.
Clinically, it is used to investigate fatigue, recurrent infections, bone or muscle pain, anaemia, and neurological symptoms.
Why do I need a Vitamin Profile test?
Deficiencies in Vitamin D, B12, and Folate are widespread in the UK, even in otherwise healthy individuals. These deficiencies can develop due to limited sun exposure, dietary habits, absorption issues, or increased physiological demand.
Symptoms may overlap and are often mistaken for stress or lifestyle-related fatigue. Testing allows accurate identification and targeted correction, avoiding unnecessary supplementation.
You may benefit from this test if you experience:
- Persistent tiredness or low energy
- Frequent infections or slow recovery
- Bone, muscle, or joint pain
- Brain fog or poor concentration
- Tingling or numbness
- Anaemia or abnormal blood results
- Limited sun exposure or dietary restrictions
Biomarkers included (3 total)
- Vitamin D (25-Hydroxyvitamin D)
- Vitamin B12 (Cobalamin)
- Folate (Vitamin B9)

- Targets the most common deficiencies
Covers three vitamins frequently low in the UK population. - Supports energy and fatigue investigation
All three nutrients are linked to energy metabolism. - Supports immune health
Vitamin D and B12 play key roles in immune function. - Assesses bone and muscle health
Vitamin D is essential for calcium metabolism. - Supports neurological function
B12 and folate are critical for nerve and brain health. - Supports anaemia assessment
B12 and folate are required for red blood cell production. - Guides safe supplementation

Your results explained
Low vitamin levels
Low levels in Vitamin D, B12, or Folate indicate deficiency, which may affect immunity, energy, bone health, neurological function, or blood formation.
Typical UK interpretation (low):
- Vitamin D: < 25 nmol/L
- Vitamin B12: < 130 ng/L
- Folate: < 3 µg/L
Normal vitamin levels
Normal results indicate adequate vitamin availability to support physiological functions.
Typical UK interpretation (normal):
- Vitamin D: 50 – 125 nmol/L
- Vitamin B12: 130 – 700 ng/L
- Folate: 3 – 20 µg/L
High vitamin levels
High levels are usually linked to supplementation. Fat-soluble vitamins such as Vitamin D require careful interpretation.
Typical UK interpretation (high):
- Vitamin D: > 150 nmol/L
- Vitamin B12: > 700 ng/L
- Folate: > 20 µg/L

Follow these guidelines for accurate results
Sample Timing
Where possible, attend your blood test between 7am and 12pm. Please wait until any short-term illness or infection has fully resolved before testing. Avoid intense exercise for 24–48 hours beforehand, as this can affect certain markers.
Fasting & Hydration
Fasting is not always required, but some tests may recommend it. If fasting is advised, avoid food for 8–12 hours before your appointment and drink water only. Stay well hydrated, as this helps with sample collection and accuracy.
Medications & Supplements
Continue prescribed medications unless advised otherwise by your clinician. Avoid vitamin, mineral, or biotin supplements for at least 24–48 hours before your test, as these can interfere with results. If you are unsure about any medication or supplement, please let us know before your appointment.
Hormones & Menstrual Cycle
For hormone-related tests, timing within your menstrual cycle may be important. If relevant, follow any specific guidance provided on your test page.
If you have any questions or special circumstances, our team is happy to advise before your appointment.
