Vitamins
4 markersActive Vitamin B12
pmol/LThe portion of B12 your cells can actually use.
Why it matters
More accurate than total B12, which can look normal while the usable fraction is low.
Vitamin D
nmol/LThe vitamin your skin makes from sunlight, essential for bone, muscle and immune function.
Why it matters
Deficiency is near-universal in northern Europe through winter, and among the easiest deficiencies to correct.
Vitamin B9 (Folate)
nmol/LVitamin B9, needed to build DNA and red blood cells.
Why it matters
Works together with B12 — treating one without checking the other can mask a serious deficiency.
