About this test

How can a vitamins blood test help you?

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.
