The body is undergoing metabolic shifts as fat oxidation increases
Conclusion Healthy B12 levels rely entirely on effective B12 intake and absorption
Moreover, if the person gets treated for the vitamin B12 deficiency and uses nitrous again after treatment, it can undo whatever progress they had made towards recovery
However, the underlying cause of the deficiency must also be addressed in order to prevent relapse and further complications
Common examples include fatigue or low energy with normal blood results, brain fog or reduced concentration without confirmed vitamin B12 deficiency, stress-related exhaustion or burnout, increased metabolic demand such as during illness recovery, high workload, or intense training, restrictive or inconsistent dietary intake, or suspected poor oral absorption despite normal serum levels
If needed for a clear medical indication (such as treating pellagra in a pregnant patient), niacinamide can be used with caution, but unnecessary high-dose B supplementation is avoided in pregnancy
