Intravenous administration results in even more rapid excretion with little opportunity for liver storage
Once injected, it is converted into these active forms, which serve as essential cofactors in key metabolic processes such as DNA synthesis, fatty acid metabolism, and neuronal myelin formation
Independent groups have characterised the compound across overlapping research model systems, providing cross-laboratory replication for the core observations documented in the foundational papers
We start with tests for serum vitamin B12 and methylmalonic acid (MMA) levels
A finished preparation should be visually transparent with no suspended particulate
