Black pepper enhances bioavailability primarily through piperine, which inhibits drug-metabolizing enzymes (such as CYP3A4) and P-glycoprotein efflux pumps in the intestinal lining. By slowing the breakdown and elimination of compounds, piperine allows higher concentrations of nutrients or drugs to enter the bloodstream. This mechanism is well-documented in increasing curcumin absorption by up to 2000% (Evidence Level: C).
Does black pepper interact with prescription medications?
Yes, black pepper and piperine supplements can interact with medications. Piperine inhibits liver enzymes responsible for metabolizing drugs, specifically cytochrome P450 pathways. This inhibition can increase the blood concentration and effects of certain drugs, such as phenytoin, theophylline, and anticoagulants, potentially leading to adverse effects or toxicity. Patients taking prescription medications should consult a healthcare provider before taking concentrated piperine extracts (Evidence Level: C).
What is the recommended dosage for black pepper extract?
For therapeutic use as a bioenhancer, the typical dosage is 5–20 mg of piperine extract daily. This amount is sufficient to improve the absorption of other nutrients like curcumin. For general digestive support, liberal culinary use of whole or ground peppercorns is standard. Concentrated supplements should be taken with food to minimize potential gastrointestinal irritation (Evidence Level: C).
Is black pepper safe to eat during pregnancy?
Black pepper is considered safe during pregnancy when consumed in normal culinary amounts. Traditional use and general consensus support its safety as a food seasoning. However, pregnant women should avoid taking high-dose piperine supplements or concentrated extracts, as the safety of these therapeutic doses has not been thoroughly established in clinical trials (Evidence Level: Traditional/C).
Who should avoid taking black pepper supplements?
Individuals with active peptic ulcers or those recovering from abdominal surgery should avoid medicinal doses of black pepper, as it may irritate the gastrointestinal mucosa. Additionally, people taking medications metabolized by the liver should exercise caution due to potential drug interactions. While culinary use is generally safe, concentrated extracts can cause GI irritation in sensitive individuals (Evidence Level: Traditional).

Résumé
Black pepper (Piper nigrum) is a widely used spice and medicinal herb characterized by its pungent alkaloid, piperine [PMID:32929825, PMID:17987447]. It is recognized for diverse pharmacological activities, including antioxidant, anti-inflammatory, and bio-enhancing effects [PMID:23625885, PMID:38405638].
Contexte
Piper nigrum, belonging to the family Piperaceae, is a climbing perennial plant used globally as a food spice, preservative, and medicinal agent [PMID:32929825, PMID:35196422].
Usages traditionnels
Traditionally used for arthritis, bronchitis, gastritis, diarrhea, snake bite, menstrual pain, fever, and bacterial infections [PMID:34996326]. In India, it is reportedly used to increase milk supply [PMID:35349239].
Composés actifs
The primary pungent constituent is the alkaloid piperine, which comprises 2-7.4% of the plant [PMID:32929825, PMID:17987447]. Other bioactive components include the lignan cubebin [PMID:36775642] and essential oil volatiles such as alpha-pinene, sabinene, beta-pinene, delta-3-carene, limonene, and beta-caryophyllene [PMID:31766491].
Mécanisme d'action
Piperine enhances the oral bioavailability of other compounds (e.g., curcumin) and drugs by modulating gastrointestinal absorption and altering the activity of transporters like p-glycoprotein and various enzyme systems [PMID:35349239, PMID:23625885, PMID:34996326]. It protects against oxidative damage by inhibiting or quenching free radicals and reactive oxygen species [PMID:17987447]. Anticancer mechanisms include inducing apoptosis and inhibiting tumor proliferation, migration, and invasion [PMID:27529277].
Preuves cliniques
Preuve CCancer
Piperine demonstrates antiproliferative, antitumor, and antimetastatic effects in various in vitro and in vivo models [PMID:32929825, PMID:38405638, PMID:40439931].
Preuve CDigestive Health
Dietary piperine stimulates pancreatic digestive enzymes, enhancing digestive capacity and reducing gastrointestinal food transit time [PMID:17987447].
Preuve CChronic Diseases
Piperine is associated with the reduction of insulin resistance and improvement of hepatic steatosis [PMID:27671817].
Preuve CCardiovascular Health
Black pepper and its terpene constituents (e.g., beta-caryophyllene) exhibit cardioprotective effects via anti-hypertensive and anti-atherosclerotic mechanisms [PMID:37299525].
Preuve CNeurological Disorders
Black pepper is noted for neuroprotective properties in the context of age-related neurological disorders [PMID:37191428].
Sécurité et effets indésirables
High daily bolus doses of isolated piperine in animal studies have indicated disturbances in spermatogenesis and maternal reproductive and embryotoxic effects [PMID:34574230].
Grossesse et allaitement
Piperine can be found in breastmilk after maternal ingestion, though levels from typical dietary amounts appear to be below the taste threshold [PMID:35349239].
Interactions médicamenteuses
Isolated piperine can interact with several drugs, typically increasing their bioavailability, which may lead to unintended or adverse drug effects [PMID:34574230, PMID:23625885].
Synthèse des preuves
The majority of evidence is derived from review articles and in vitro/in vivo experimental trials (Level C and D), indicating strong pharmacological potential but a need for more clinical trials in humans.
