Cordiart, a sweet-orange extract rich in the citrus compound hesperidin, sold as a supplement ingredient, is marketed to keep arteries flexible. Related orange extracts showed small exercise-power gains, but artery, blood-pressure, cholesterol and blood-sugar results conflict, and the product's own main study found no clear blood-vessel benefit. Safety looks good in short trials, though citrus compounds can reduce absorption of some blood-pressure and allergy medicines. The promised benefit remains unproven. (Full Review)
| Marker | Target | Why |
|---|---|---|
| Home blood pressure | 110–120 / 70–80 mmHg | Main vascular target; hypotension check |
| LDL cholesterol | Below 100 mg/dL (below 70 mg/dL with high risk) | Tracks lipid effect |
| High-sensitivity CRP | Below 1.0 mg/L | Tracks inflammation |
| Fasting glucose | 75–90 mg/dL | Tracks glycemic effect |
| HbA1c | Below 5.4% | Three-month glucose average |
| ALT | Below 25 U/L | Liver-fat and safety marker |
| FMD | No established optimal target; track change from own baseline | Direct artery-function readout |
| Body weight and waist | Stable within ±1 kg of baseline | Detects possible weight gain |
| INR (warfarin users) | Test at 1–2 weeks after starting | Detects altered anticoagulation |
Cadence: Baseline before starting; home blood pressure twice weekly for the first four weeks, then monthly; weight monthly for three months; repeat blood tests at 6–8 weeks, then every 6–12 months; warfarin users add an INR test at 1–2 weeks.
