HighWhat the studies found
By outcome
Black Pepper Extract has an evidence score of 7.5/10 — strong evidence based on 47 indexed studies, including 10 meta-analyses. Inhibits drug-metabolizing enzymes to boost absorption of curcumin, CoQ10, and other supplements by up to 2,000%.
The commonly studied dose of Black Pepper Extract is 5-20mg piperine daily. Research points to an estimated optimal dose around 15mg, with a minimum effective dose near 5mg. Individual response varies — start low and adjust.
The best time to take Black Pepper Extract is with meals. Take it with food. Piperine inhibits UDP-glucuronosyltransferase, CYP3A4, and P-glycoprotein efflux pumps in the intestine and liver.

Black Pepper Extract, standardized to piperine (commonly sold as BioPerine), is best known as a bioavailability enhancer. It can dramatically increase the absorption of many supplements including curcumin, CoQ10, resveratrol, and vitamins. Piperine works by inhibiting enzymes that metabolize compounds and by increasing intestinal absorption.

5-20mg piperine daily
Loading: Not required; take with the supplement you want to enhance
Take with food
| Form | Type |
|---|---|
| 💊BioPerine (95% piperine standardized extract) | Recommended |
| 💊Generic piperine extract | Alternative |
| 🧪Black pepper powder (much less potent) | Alternative |
BioPerine is the most researched branded form. 5mg BioPerine = approximately 1 tsp black pepper.
Minimum: 1 weeks
Optimal: 4 weeks
Cycling: Not required
Note: Take at the same time as the supplement you want to enhance (e.g., curcumin, CoQ10).
Evidence from multiple studies showing piperine enhances absorption of co-administered compounds like curcumin. Most studies used 5-20mg range. Conservative effectiveness estimates due to variable study designs and co-administration contexts. May also enhance drug absorption leading to potential interactions.
Dramatically increases absorption of many supplements
Can also increase absorption of medications
Consult pharmacist or doctor before use
Can increase blood levels of many drugs including statins, blood thinners, antidepressants
May alter drug levels; avoid without oncologist guidance
Tip: Take with food
Black Pepper Extract is generally safe at recommended doses, with a few precautions worth noting. The most commonly reported side effects are GI irritation. Use caution if any of these apply to you: Taking medications with narrow therapeutic windows.
