SelectedWhat is the Vitamin Profile 2 test?
Vitamin Profile 2 is a comprehensive micronutrient blood test that measures a wide range of fat-soluble and water-soluble vitamins essential for metabolic, neurological, immune, and skeletal health. It provides a detailed overview of nutritional status rather than focusing on a single vitamin.
This profile includes vitamins involved in energy production, nerve signalling, red blood cell formation, antioxidant defence, immune regulation, and bone metabolism. Some vitamins are measured in their most clinically relevant forms, such as Active Vitamin B12 and Red Cell Folate, offering greater diagnostic accuracy.
Vitamin Profile 2 is commonly used when symptoms are broad or unexplained, when multiple deficiencies are suspected, or for proactive health optimisation and monitoring.
Why do I need a Vitamin Profile 2 test?
Vitamin deficiencies often present with non-specific symptoms such as fatigue, brain fog, low immunity, or musculoskeletal pain. Testing a single vitamin may miss combined or interacting deficiencies that affect multiple systems.
This profile is especially valuable for people with digestive or absorption disorders, restrictive diets, chronic illness, high stress, or long-term medication use. It allows targeted correction rather than blind supplementation, reducing the risk of under- or over-treatment.

Your results explained
Low vitamin levels
Low levels in one or more vitamins indicate nutritional deficiency, impaired absorption, or increased metabolic demand. Deficiencies can affect energy, immunity, neurological function, bone health, and antioxidant protection.
Typical UK interpretation (low):
Low results may explain fatigue, infections, nerve symptoms, bone pain, or anaemia.
Normal vitamin levels
Normal results suggest adequate vitamin availability to support metabolic, immune, neurological, and skeletal functions.
Typical UK interpretation (normal):
Symptoms are unlikely to be caused by vitamin deficiency alone.
High vitamin levels
High levels are usually linked to supplementation. Fat-soluble vitamins (A, D, E) require careful interpretation due to storage in the body.
Typical UK interpretation (high):
Persistently elevated levels may require dose adjustment or clinical review.

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 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.
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.
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.
