Patients on long-term loop diuretics might benefit from B supplementation, and the B-Complex Injection can help replete thiamine in those individuals

Unlike deficiency states, which produce well-characterised neurological and haematological symptoms, there is no clearly defined clinical syndrome associated with B12 excess from supplementation alone
However, a very small number of peptides can have solubility or stability issues with benzyl alcohol
