Supplement
Black pepper is a common spice whose active compound, piperine, gives it its bite and slows some of the enzymes your body uses to break down nutrients. People mostly look at it to help the body absorb other compounds, and studies found it raised absorption of curcumin, CoQ10, beta-carotene, selenium, vitamin B6 and resveratrol, with the evidence rated moderate. Findings on inflammation and metabolic rate were limited, and most studies were fairly small.

| Grade | Outcome | Effect | Size | Studies | People | Studies list |
|---|---|---|---|---|---|---|
| Curcumin Bioavailability 20mg piperine increased curcumin bioavailability by 2000% in humans (PMID: 9619120); consistent enhancement across multiple studies | Improves (the measure goes up) | Large effect | 60 people |
| Grade | Outcome | Effect | Size | Studies | People | Studies list |
|---|---|---|---|---|---|---|
| Nutrient/Drug Absorption Piperine enhances absorption of CoQ10, beta-carotene, selenium, vitamin B6, and resveratrol via enzyme inhibition | Improves (the measure goes up) | Moderate effect | 200 people |
Inflammation
- Inflammatory Markers: improves
| Grade | Outcome | Effect | Size | Studies | People | Studies list |
|---|---|---|---|---|---|---|
| Inflammatory Markers Modest reduction in inflammatory markers; synergistic anti-inflammatory effect when combined with curcumin | Improves (the measure goes down) | Small effect | 120 people |
Metabolic Health
- Thermogenesis: improves
| Grade | Outcome | Effect | Size | Studies | People | Studies list |
|---|---|---|---|---|---|---|
| Thermogenesis TRPV1 activation increases thermogenesis; modest effect on metabolic rate in humans | Improves (the measure goes up) | Small effect | 40 people |
