B12 can be tricky to pin down. It can be falsely elevated by vitamins. You need cofactors, e.g. a B2 deficiency could falsely give the impression of repletion.

This is ON TOP of the really loose grounding of accepted ranges for various vitamins. Many of the levels are established on the basis of avoiding severe disease like vitamin D: "no rickets above this level" and B12: "no anemia above this level." Which is completely different than assessing optimal levels.

Many of the levels are established on the basis of avoiding severe disease like vitamin D: "no rickets above this level" and B12: "no anemia above this level." Which is completely different than assessing optimal levels. This is concerning. Is there anyone keeping a database of optimal rather than minimal levels?
