Vitamin B12
Vitamin B12 is a clinical biomarker on the Nutrients panel, reported in pg/mL. Standard reference range: 200–1100 pg/mL. Functional (optimal) range used by integrative practitioners: 525–1100 pg/mL.
What is Vitamin B12?
Vitamin B12 (cobalamin) is essential for DNA synthesis, myelin formation, and the conversion of methylmalonyl-CoA to succinyl-CoA; deficiency causes megaloblastic anemia and neurological damage.
Reference ranges
| Range type | Value (pg/mL) | Source |
|---|---|---|
| Standard (lab) | 200–1100 | Typical Quest / LabCorp adult reference |
| Functional (optimal) | 525–1100 | Integrative / functional medicine consensus |
How SomaVue interprets Vitamin B12
SomaVue maps every result for Vitamin B12 against four clinical lenses — nutrient cofactors, toxin exposure, infection drivers, and circadian/hormonal context — and connects each interpretation to specific peer-reviewed citations. Pre-mapped clinical reasoning and cross-marker pattern detection are available inside the practitioner workspace.
