Hesperidin, the main plant compound in oranges and sold as a supplement for circulation and metabolic health, most clearly lowers blood fats and eases vein-related leg symptoms. Blood pressure and inflammatory markers improve mainly in people who already have a metabolic disorder; blood sugar control does not respond. Stomach upset is the main complaint. Gut bacteria must release the active form, so response varies widely between people. (Full Review)
| Marker | Target | Why |
|---|---|---|
| LDL cholesterol | < 100 mg/dL; < 70 mg/dL with existing vascular disease | Primary endpoint with the strongest pooled evidence |
| Total cholesterol | 150–200 mg/dL | Second lipid endpoint reduced in pooled trials |
| Triglycerides | < 100 mg/dL | Reduced in the broader cardiometabolic synthesis |
| High-sensitivity C-reactive protein | < 1.0 mg/L | Tracks the inflammatory effect, the clearest signal after lipids |
| Fasting glucose and insulin | Glucose 70–85 mg/dL; insulin < 6 µIU/mL | Establishes metabolic status, which predicts whether any benefit will appear |
| HbA1c | < 5.4% | Confirms the pooled finding of no glycemic effect at the individual level |
| Alanine aminotransferase and gamma-glutamyl transferase | ALT < 25 U/L (men), < 20 U/L (women); GGT < 20 U/L | The liver-fat endpoint from the fatty liver disease trial |
| Home systolic blood pressure | < 120 mmHg | Detects both the intended reduction and excessive lowering on combined therapy |
| Platelet count | 150–400 × 10⁹/L | Baseline for anyone on antiplatelet or anticoagulant therapy |
| Body weight and waist circumference | Weight: change from own baseline; waist < 94 cm (men), < 80 cm (women) | Tests the pooled weight-gain signal in the individual |
Cadence: Baseline, first recheck at 12 weeks, then at 6 months, then annually once a response is established; home blood pressure logged weekly for the first four weeks in anyone on antihypertensive therapy.
