About this trial
This randomized, double-blind, crossover trial (Phase IV) aims to compare the absorption of a novel permeability-enhanced oral vitamin B12 formulation (Ampli-B) versus standard oral vitamin B12 in 12 healthy adults aged 50 years and older. Each participant receives a single dose of each formulation in randomized sequence, separated by a minimum 10-day washout. The primary outcome is time to peak serum concentration (Tmax) of total and active vitamin B12 (holotranscobalamin). Secondary outcomes include Cmax and AUC parameters.
