Investigations were made on the absorbing mechanism of vitamin B_6. Vitamin B_6 was rapidly absorbed from small intestines in the order of pyridoxal, pyridoxine and pyridoxamine. Kallikrein and pituitrin acclerated the absorption, epinephrine inhibited it and insulin, thyroid hormone, cardiac hormone, sexual hormone and parotic hormone had no influence on the absorption. The effcts of bile and cholic acid on the absorption were uncertain. From these observations, the author supposed that vitamin B_6 was absorbed mainly by the physico-chemical processes, such as diffusion, osmosis etc., and a smaller part by phosphorylation.
