This study aimed to investigate the effects of germinated black Hang rice extract on nutritional composition, blood glucose levels, lipid profiles, and toxicity markers in overweight and obese elderly. A randomized, double‐blind, placebo‐controlled trial involving 30 participants was conducted. They were assigned to either control group (CG), which received maltodextrin, or treatment group (TG), which received germinated black Hang rice extract. A dose of 500 mg/capsule, 2 capsules/day, was orally administered to both groups for 8 weeks. The outcomes analyzed included nutritional composition, blood glucose levels, lipid profiles, hematological parameters, and liver and kidney functions. The germinated black Hang rice extract was found to be rich in gamma‐aminobutyric acid (GABA) at 2.45 mg/100 g and dietary fiber at 20.36 g/100 g. After 8 weeks of supplementation, the treatment group showed a significant decrease in LDL compared to the (CG: 150.31 ± 9.11 before and 180.96 ± 14.76 after; TG: 149.65 ± 8.84 before and 141.09 ± 10.77 mg/dL after, p < 0.05). Data including HbA1C, FBG, cholesterol, triglyceride, and HDL were not significantly different between groups. Moreover, hematological parameters and kidney and liver functions remained within normal range, indicating no toxicity. In conclusion, germinated black Hang rice extract significantly reduced LDL levels, potentially as a safe dietary for lipid management in overweight and obese elderly people.
