The study was carried out to evaluate the role of fermented single bulb garlic (FSBG) with lactobacillus plantarum B1765 toward insulin–glucagon axis in Type 2 diabetes mellitus (T2DM). The research assessed the influences of FSBG administration at doses of 100, 200, and 300 mg/kg, (while metformin (9 mg/kg) served as the reference treatment) on the insulin regulation and secretion of glucagon in experimental rats induced with a high-fat diet (HFD) and 20 mg/kg streptozotocin (STZ). The outcomes indicate that FSBG effectively reduced insulin–glucagon axis secretion with the optimal effect observed at a dose of 300 mg/kg. While the reduction in insulin levels achieved by FSBG was not significantly different from that of metformin, FSBG demonstrated a superior effect in lowering glucagon levels. Hence, FSBG can serve as a potential alternative antidiabetic agent, offering beneficial bioactive compounds suitable for long-term consumption compared to conventional drugs such as metformin, which may cause adverse side effects. © 2026 Nazarend et al.
