A natural, intensely sweet extract whose sweet compounds are barely absorbed and do not raise blood sugar. Its clearest value is replacing sugar without the calories or blood-sugar rise. Broader antioxidant, anti-inflammatory, and throat-soothing claims stay unproven in people. Most reported downsides trace to the erythritol filler, not monk fruit itself; pure products avoid them.

| Marker | Target | Why |
|---|---|---|
| Fasting glucose | 70–85 mg/dL | Tracks whether cutting sugar improves fasting glucose control |
| HbA1c | < 5.4% | Captures the sustained glucose benefit of replacing sugar |
| Fasting insulin | < 6 µIU/mL | Detects improving insulin sensitivity as sugar load falls |
| Triglycerides | < 90 mg/dL | High sugar intake raises triglycerides, so reduction signals success |
| hs-CRP | < 1.0 mg/L | Gauges low-grade inflammation, relevant to the antioxidant rationale |
Cadence: Baseline before a deliberate substitution; for metabolic use, re-check glucose and HbA1c at ~3 months, then every 6–12 months; otherwise no scheduled labs
