About This Test

Why Vitamin B12 Really Matters

Vitamin B12 plays a quiet but critical role in energy production, nerve protection and blood cell formation. Because your body can’t make it, levels depend on diet and absorption. A B12 blood test shows whether your current level is enough or whether a shortfall could explain ongoing tiredness, low mood or neurological symptoms that don’t seem to add up.
