Moreover, the total abdominal and subcutaneous fat areas were significantly decreased following 2855 mg of PGE supplementation (p < 0.05). Regarding the safety hepatic and renal function markers in plasma were analyzed for safety assessment. When all participants were analyzed (n = 100), there were no significant changes (p > 0.05) in the safety-related markers of liver or renal function among the four groups.
