Hydroxycitric acid tripotassium hydrate (Potassium citrate monohydrate) is the major active ingredient of Garcinia cambogia and a derivative of citric acid. Hydroxycitric acid tripotassium hydrate competitively inhibits ATP citrate lyase with weight loss benefits. Hydroxycitric acid tripotassium hydrate effective inhibits stones formation and also inhibits HIF, and has antioxidation, anti-inflammation and anti-tumor effects.

HCA (Hydroxycitric acid) treatment could reduce markers of renal impairment (Blood Urea Nitrogen and serum creatinine). There was significantly less calcium oxalate crystal deposition in mice treated with HCA. Calcium oxalate crystals induced the production of reactive oxygen species and reduced the activity of antioxidant defense enzymes. HCA attenuated oxidative stress induced by calcium oxalate crystallization. HCA had inhibitory effects on calcium oxalate-induced inflammatory cytokines, such as MCP-1, IL- 1 β, and IL-6. In addition, HCA alleviated tubular injury and apoptosis caused by calcium oxalate crystals[5]. Hydroxycitric acid shows an HIF inhibitory effect compared with the control group in ARPE19 cells and 661W cells. Hydroxycitric acid can downregulate Hif1a and the downstream genes in ARPE19 cells and 661W cells. Hydroxycitric acid suppresses HIF-1α protein expression increased by CoCl2 administration in ARPE19 cells and 661W cells[6].
