A four-week hold is roughly the window needed for a step to reach steady state and for the gut to adapt to it, which is why escalating before the block is complete effectively means judging a dose you have not yet fully experienced
Risk factors that should prompt consideration of B12 deficiency include advancing age (reduced stomach acid production), strict vegan or vegetarian diets, pernicious anaemia, gastrointestinal surgery (particularly gastric bypass or ileal resection), long-term use of certain medications (metformin, proton pump inhibitors, H2-receptor antagonists), nitrous oxide exposure (including recreational use), and conditions affecting the gut such as Crohn's disease or coeliac disease
Their cost-effectiveness and favorable pharmacokinetic properties (e.g., efficient absorption and potent bioactivity) make them attractive candidates for localized and targeted wound therapies [29, 54-57]
