About this test

How can a vitamins blood test help you?

This blood test is helpful if you want to measure your overall vitamin levels. Detecting a vitamin deficiency can help you understand if this could be linked to getting sick often, low energy levels, irritability, and feeling anxious.

Find out more about vitamin deficiencies, including:

  • vitamin D deficiency
  • vitamin B12 deficiency
  • vitamin B9 (folate) deficiency

Combined with a GP report and advice on how to improve or maintain your vitamin levels, we help you understand how to support your body.

We recommend taking a vitamins blood test every 3 months if you have a deficiency.

What's covered in this blood test?

  • Vitamin D: Vitamin D plays an essential role in your long-term health, particularly your bone health. It's also important for a strong immune system and is linked to your sleep, energy levels, and mood.
  • Vitamin B9 and B12 (active): An active vitamin B9 and B12 test measures the amount of vitamin B12 your body can actually use. It's essential for a healthy brain and nervous system. Both vitamins are linked to sleep, mood, and heart health.
