Potassium citrate tribasic solution is provided as a 1M solution in water. Used in the laboratory as a buffering agent and chelator. In renal function studies, potassium citrate is used as an alkanizing agent where the citric acid is a metabolic substrate in renal cells. Studies have shown that potassium citrate may increase bone density, it is therefore used in research experiments related to the treatment of osteoporosis.|Also available: Potassium citrate monobasic ; Potassium citrate tribasic monohydrate .
