Black Pepper is a source of piperine, a molecule that does not do much on its own but can inhibit enzymes that would attack other molecules. Due to this, it is ingested alongside some supplements to increase their absorption rates and is almost always consumed with curcumin.

Sources and Pharmacology
Black Pepper (Piper Nigrum) is a common spice and herb used historically for various diseases related to gastrointesinal disorder and dental or oral dysfunction. It is most commonly known in the supplemental realm for its piperine content, but also contains pellitorine, guineensine, pipnoohine, trichostachine, and piperonal.
Piperine is known for changing metabolism of various drugs and supplements, most notably increasing curcumin bioavailability by 2000%. It affects metabolism by both intestinal absorption as well as downregulating or inhibiting phase II detoxification enzymes and the glucuronidation process in the liver. It may also contribute to increase absorption by slowing intestinal transit rate and thus prolonging the time said compounds are exposed to the potential uptake.
Gastric and Systemic Effects
Safety and toxicity
There exist preliminary evidence that black pepper as a food substance poses carcinogenic effects via some procarcingenic constituents such as safrole and tannins, and some terpene compounds. These procarcinogenic effects were noted with topical application.: Evidence of carcinogenicity]. These effects, however, were not noted with oral ingestion despite rodent hypersensitivity to piperine.
It is generally recognized as safe for human consumption.
