What's covered in this blood test?

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.

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.
