- Baxter , JH . 1968 . “Absorption of Chlorophyll Phytol in Normal Man and in Patients with Refsum's Disease” . J Lipid Res , 9 : 636 – 641 . The metabolism of chlorophyll in vivo has not been studied extensively. reported that most of the ingested dietary chlorophylls (95%) were recovered in the feces as pheophytins, a chlorophyll‐like compound rendered free of Mg ++ by stomach acid. Since free phytol is readily absorbed, the author suggested that the phytyl‐ester linkage in the chlorophyll molecule is resistant to action of intestinal enzymes.
