| How it works | Activates AMPK by the same energy-sensor route as metformin. The AMPK switch → the AMPK pathway. Downstream: lowers hepatic glucose output, improves insulin sensitivity, shifts fuel toward fat oxidation, and reshapes gut microbiota. Its… | Dual agonist of GIPR (GIP receptor) and GLP1R. GIP receptor activation in the hypothalamus and adipose tissue synergises with GLP-1, producing greater appetite suppression and fat loss than GLP-1 alone. |
| In plain English | "Nature's metformin" — it flips the same low-fuel switch (AMPK). Best for pre-diabetes and high triglycerides. Poorly absorbed, so split the dose with meals or use dihydroberberine. | Hits two "I'm full" gut-hormone switches at once instead of one — so it works even better. SURMOUNT-1: 22.5% bodyweight lost, approaching bariatric-surgery territory. |
| Bottom line | Strong metabolic supplement; pair with glucose monitoring. | Currently the most effective approved obesity drug. |
| Availability | Available over the counter | Prescription only |
