Lithium citrate (Litarex) tetrahydrate is the major active ingredient of Garcinia cambogia. Lithium citrate tetrahydrate competitively inhibits ATP citrate lyase with weight loss benefits. Lithium citrate tetrahydrate effective inhibits stones formation and also inhibits HIF, and has antioxidation, anti-inflammation and anti-tumor effects[1][2][3][4].
Lithium citrate tetrahydrate shows an HIF inhibitory effect compared with the control group in ARPE19 cells and 661W cells. Lithium citrate tetrahydrate can downregulate Hif1a and the downstream genes in ARPE19 cells and 661W cells. Lithium citrate tetrahydrate suppresses HIF-1α protein expression increased by CoCl2 administration in ARPE19 cells and 661W cells[2].
In chicken hepatocytes, Lithium citrate tetrahydrate decreases the accumulation of lipid droplets and accelerated energy metabolism. Lithium citrate tetrahydrate protects the cells from ER stress by increasing the antioxidant status and mitochondrial functions[2].
Lithium citrate (100-200 mg/kg) tetrahydrate treatment could reduce markers of renal impairment (Blood Urea Nitrogen and serum creatinine). There is significantly less calcium oxalate crystal deposition in mice (male C57BL/6J mice) treated with Lithium citrate tetrahydrate. Lithium citrate tetrahydrate attenuates the oxidative stress induced by calcium oxalate crystallization. Lithium citrate tetrahydrate has inhibitory effects on calcium oxalate-induced inflammatory cytokines, such as MCP-1, IL-1 β, and IL-6. In addition, Lithium citrate tetrahydrate alleviates tubular injury and apoptosis caused by calcium oxalate crystals[1].
The administration of Lithium citrate tetrahydrate can suppress body weight gain and fat accumulation in animals[3].
