| Marker | Target | Why |
|---|---|---|
| LDL Cholesterol | < 100 mg/dL | Tracks the most reproducible catechin benefit |
| Total Cholesterol | < 180 mg/dL | Captures overall lipid response |
| Blood Pressure | < 120/80 mmHg | Detects the small blood-pressure effect |
| Ferritin | 50–150 ng/mL | Guards against iron depletion from catechins |
| ALT | < 25 U/L | Screens for the rare catechin liver effect |
| Fasting Glucose / HbA1c | < 90 mg/dL / < 5.4% | Monitors glycemic response |
Cadence: Baseline, then 8–12 weeks; every 6–12 months thereafter (liver enzymes every 3–6 months with concentrates)
