Hi, I would like to know the percentage of absorption in the three routes of consumption of mb12: injections(IM), sublinguals, and oral route. I know it is variable and differs from person to person, but a rough estimation of how much of the amount consumed is actually absorbed by us in each of the three routes would be really helpful. I read somewhere that injections have 50 % absorption, sublinguals around 25 % and oral around 2 %. I would like to know if this information is correct or not. Thanks!
