Description
Yoshihide Ogawa reviews in 2026 more than forty years of rat research on where the oxalate behind many kidney stones actually comes from. Advice to patients has long stressed avoiding oxalate-rich foods, yet the body itself makes much of the oxalate found in urine.
Experiments tracked how several chemical precursors convert into oxalate, with two compounds proving most potent. Lack of vitamin B6 stood out as a gatekeeper: deficiency raised conversion rates dramatically in some tests by weakening a liver enzyme. Ogawa argues stone prevention should shift toward managing precursor load and correcting B6 status, rather than relying on diet restriction alone.
