The absorption process is highly efficient at physiological doses, with approximately 50% of dietary B12 absorbed when consuming around 1 microgram

Animal data indicates rapid clearance typical of unmodified small peptides, generally minutes to low hours in plasma

The next question is why B12 becomes low in the first place
