Naringin is a citrus flavonoid the body converts into the more active naringenin. Laboratory and animal research shows wide-ranging promise — calming inflammation, reducing cell damage, improving blood fats, and protecting organs — but human evidence is scarce and absorption is poor, so its real value for long-term health remains genuinely uncertain.

| Marker | Target | Why |
|---|---|---|
| LDL cholesterol | < 100 mg/dL | Tracks the most plausible lipid benefit |
| Triglycerides | < 80 mg/dL | Flavanones may modestly lower triglycerides |
| HDL cholesterol | > 50 mg/dL (women), > 40 mg/dL (men) | Possible small increase reported |
| hs-CRP | < 1.0 mg/L | Reflects the anti-inflammatory effect, if any |
| ALT / AST | ALT < 25 U/L, AST < 25 U/L | Safety: detects any liver stress at higher doses |
| eGFR / creatinine | eGFR > 90 mL/min/1.73 m² | Safety: monitors kidney function with chronic use |
| Fasting glucose | 70–90 mg/dL | Tracks any metabolic effect |
Cadence: Baseline before starting; retest at 8–12 weeks, then every 6–12 months if continued, with liver and kidney function checked if used at concentrated doses long-term.
