Vitamin Test (A, B3, B5 & Biotin)

About this test

Key Benefits

• Measure important vitamins such as A, B3, B5, and biotin, which play key roles in overall health

• Gain insight into energy levels, skin, hair, and nervous system function

• Helps identify potential vitamin deficiencies that may not be routinely tested

• Useful for those on restricted or specialized diets, including vegans

• Supports more informed decisions around nutrition and supplementation

• Simple at-home blood test, no clinic visit required

What This Test Measures

This test analyzes:

• Vitamin A (Retinol): Important for vision, skin, and normal cell function

• Vitamin B3 (Niacin): Supports energy metabolism, helps reduce fatigue, and contributes to nervous system function

• Vitamin B5 (Pantothenic acid): Involved in energy production, mental performance, and hormone synthesis

• Vitamin B7 (Biotin): Supports hair, skin, and macronutrient metabolism

These vitamins are essential for maintaining normal body functions, including energy production, skin health, and overall nutritional balance.

Who Should Take This Test?

This test is suitable for individuals who want to better understand their vitamin levels, especially those experiencing fatigue, hair loss, or skin issues. It may also be relevant for people with restricted diets, such as vegans, or anyone looking to optimize their nutritional intake.

How It Works and Sample Collection

Order your kit online, collect a finger-prick blood sample at home, and send it back using the prepaid envelope. Your digital results are provided once the analysis is complete.

For best accuracy, the test should be taken in the morning while fasting.

Analysis Method and Laboratory

Your sample is analyzed in an accredited laboratory using ELISA, HPLC, and LC-MS, ensuring high precision, accuracy, and reliable results.

Biomarkers included

• Vitamin B12: Vitamin B12 (cobalamin) is a water-soluble vitamin essential for DNA synthesis, red blood cell formation, and neurological function. It's primarily found in animal products, making vegetarians and vegans at higher risk of deficiency. B12 deficiency can lead to pernicious anemia, fatigue, neurological problems (including numbness, tingling, and memory issues), and elevated homocysteine levels, incr
• Coenzyme Q10: CoQ10 (Coenzyme Q10) is a vital compound that plays a key role in energy production within every cell of the body. It also functions as a powerful antioxidant, helping to protect cells from oxidative damage. CoQ10 is essential for supporting overall health and proper cellular function.
• Vitamin D: Vitamin D is a fat-soluble vitamin crucial for calcium absorption and bone health, playing a key role in phosphorus metabolism and immune system function. Its importance extends to muscle function, nerve signaling, and reducing inflammation. Maintaining adequate vitamin D levels is vital for overall well-being and disease prevention.
• Vitamin E: Vitamin E is a fat-soluble vitamin and a powerful antioxidant that protects cells from damage caused by free radicals. It is crucial for immune function, skin health, and red blood cell formation. Measuring Vitamin E levels helps assess nutritional status and antioxidant capacity.
• Folate: Folate (vitamin B9) is a water-soluble vitamin essential for DNA synthesis, cell division, and normal red blood cell formation. It is especially important during pregnancy because adequate folate status supports early fetal development and helps reduce the risk of neural tube defects. Folate also participates in methylation pathways and homocysteine metabolism, where low folate can contribute to e

How to prepare

**1-2 weeks before:** Avoid high-dose vitamin supplements, unless you want it reflected in your results. **24-48 hours before:** No alcohol, smoking or excessive caffeine and excerise. **8-12 hours before:** Only drink water. **Medications:** Medications, such as retinoids (for Vitamin A), corticosteroids, and antibiotics, can influence vitamin levels.
