About
Black pepper (Piper nigrum L.) is the dried fruit of a tropical vine native to the Malabar Coast of India, used globally as a spice and flavoring agent. Its primary bioactive alkaloid, piperine (typically 3–9% by dry weight), imparts the characteristic pungent taste and contributes antioxidant, anti-inflammatory, and drug bioavailability-enhancing properties.
Safety summary
At culinary doses, black pepper is considered safe for the general population and is GRAS-listed by the FDA; dietary piperine exposure from food does not cause adverse health effects. High-dose isolated piperine supplements can inhibit drug-metabolizing enzymes, significantly increasing the bioavailability of co-administered drugs and potentially causing unintended adverse drug effects. Animal studies at high bolus piperine doses have shown embryotoxic effects and disturbances of spermatogenesis, warranting caution for pregnant women and those on multiple medications.
Regulatory landscape
| Jurisdiction | Status | Note |
|---|---|---|
| EFSA (European Food Safety Authority) (European Union) | Approved | Piperine (FL-no: 14.003), the principal bioactive of black pepper, was evaluated by EFSA's CEF Panel in FGE.86Rev2 (2015) as a flavoring substance. A NOAEL of 5 mg/kg bw/day was established from a 90-day rat dietary study. Black pepper as a whole spice is not restricted as a food additive; piperine derivatives are listed in the EFSA Compendium of Botanicals as substances of potential toxicological concern at high isolated doses, but no ADI or maximum limit applies to culinary use.source |
| FSSAI (Food Safety and Standards Authority of India) (India) | Approved | Black pepper (Piper nigrum L.) is a notified food spice regulated under FSS (Food Products Standards and Food Additives) Regulations, 2011, Chapter 2.9. Standards specify limits for moisture, piperine content (minimum % on dry basis), volatile oil, total ash, acid-insoluble ash, and microbiological contamination. Product must be free from added colouring matter and extraneous harmful substances.source |
| FDA (Food and Drug Administration) (United States) | Approved | Black pepper is explicitly listed by the FDA as an example of a GRAS (Generally Recognized as Safe) spice under 21 CFR Part 182. No maximum daily intake is established for whole pepper at culinary use levels. Piperine as a flavoring is also FEMA GRAS-evaluated.source |
