Some studies suggest that sublingual cyanocobalamin (131-133) and sublingual methylcobalamin (134, 135) are effective at increasing vitamin B 12 status
The corresponding pharmacokinetic parameters are listed as follows: T max = 0.167 h, C max = 155 11.8 ng Eq./ml, AUC 0t = 4945 417 h ng Eq./ml, AUC 0 = 12956 2074 hng Eq./ml, average residence time (MRT 0-t ) of plasma total radioactivity = 33.2 1.03 h, and t 1/2 = 102 h (Table 9)
