How phosphate levels are detected in mammals is unknown. The bone-derived hormone fibroblast growth factor 23 (FGF23) lowers blood phosphate levels by reducing kidney phosphate reabsorption and 1. 25(OH)2D production. but phosphate does not directly stimulate bone FGF23 expression. https://www.duospiritalis.com/limited-deal-Radio-Birdman-Rock-Roll-Soldiers-T-Shirt-super-grab/
