<prompt> Inhibition of bile secretion will NOT reduce the intestinal absorption of:Vitamin AVitamin B1Vitamin KVitamin D  <response>: Inhibition of bile secretion will have little effect on the intestinal absorption of a water-soluble vitamin B1 thiamine. All of the other structures listed are fat-soluble and for a successful intestinal absorption should be emulsified by the bile acids glycocholic and taurocholic acid.
