Black pepper's health relevance comes almost entirely from one compound, piperine. Its clearest, most reliable effect is boosting how much of certain other compounds—above all turmeric's curcumin—reaches the bloodstream. Broader benefits for cholesterol, inflammation, and blood sugar almost always test piperine combined with curcumin, leaving its own contribution uncertain. The same property is also its main risk.

| Marker | Target | Why |
|---|---|---|
| Triglycerides | < 100 mg/dL | Tracks the main lipid benefit of curcumin-piperine |
| Total & LDL cholesterol | LDL < 100 mg/dL (lower if high-risk) | Captures lipid-lowering effect |
| HDL cholesterol | > 50 mg/dL (women), > 40 mg/dL (men) | May rise modestly with the combination |
| hs-CRP | < 1.0 mg/L | General marker of inflammation that the combination may lower |
| Fasting glucose | 70–85 mg/dL | Tracks any glycemic effect in metabolic users |
| ALT / AST | ALT < 25 U/L (women), < 30 U/L (men) | Liver enzymes; baseline matters because piperine inhibits liver clearance of drugs |
Cadence: Baseline before starting, then ~8–12 weeks after starting, then every 6–12 months (more frequent if interacting medications are involved)
