Details about Vitamin B5 (Pantothenic Acid)

What is a Vitamin B5 test?

A Vitamin B5 test measures the level of pantothenic acid in your blood. Vitamin B5 is essential for the production of coenzyme A, which is critical for converting fats, carbohydrates, and proteins into usable energy.

It also plays a key role in adrenal hormone production, skin health, and nervous system function.

Why do I need a Vitamin B5 test?

Low Vitamin B5 levels may contribute to fatigue, poor stress tolerance, and skin issues, often without obvious cause.

Reasons for testing include:

• Persistent fatigue
• High stress levels or burnout
• Acne or skin problems
• Poor concentration
• Digestive issues or malabsorption
• Restricted or poor diet

Benefits of the test

1. Assesses cellular energy production

2. Supports adrenal and stress response evaluation

3. Helps explain fatigue and burnout

4. Supports skin and nerve health assessment

5. Detects hidden nutritional deficiency

6. Important for metabolism of fats and carbohydrates

7. Useful in digestive or absorption issues

8. Guides precise supplementation

Expanded benefit explanation
Vitamin B5 is vital for energy metabolism and adrenal function. Identifying deficiency helps address fatigue, stress intolerance, and skin concerns.

How to Prepare for Your Test

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.

Frequently Asked Questions

The test quantifies pantothenic acid — Vitamin B5 — in your blood, reflecting your biochemical status of this micronutrient. Pantothenic acid is essential for energy metabolism, fatty acid synthesis, and adrenal hormone production.

No. Unlike lipid or glucose tests, a Vitamin B5 Test does not require fasting. You can eat and drink normally before your appointment.

Symptoms can be non-specific but may include fatigue, abdominal discomfort, tingling in hands or feet, irritability, or poor stress tolerance. Because these overlap with other deficiencies, testing helps clarify if B5 is a contributor.

Yes. Recent use of high-dose B-vitamin supplements can elevate pantothenic acid levels temporarily. Disclose any supplement use before the test so your clinician can interpret accordingly.

The test is performed in a UKAS-accredited laboratory using high-performance liquid chromatography (HPLC), which is a highly precise and validated method for measuring small-molecule nutrients like Vitamin B5.

A level below the normal range may signal insufficient dietary intake, impaired absorption, or increased demand. It should prompt nutritional review and possible dietary or supplement intervention.

Yes. We offer at-home phlebotomy blood draws across various UK locations, with a trained professional visiting your home or hotel to collect the sample.

Results are typically ready within 10 business days from when your sample reaches the lab, with notifications sent to your secure online portal.

The GP consultation is optional, but recommended if your results are outside the normal range or if you need guidance on diet, supplements, or further testing.

Vitamin B5 results are most informative when interpreted alongside other B-vitamin tests (e.g., B6, B12, Folate) and metabolic markers to provide a complete nutritional profile.
