Piperine is a bioactive alkaloid found in black pepper (Piper nigrum) and long pepper. It is commonly used in supplements to enhance the absorption of certain compounds.

How does piperine increase bioavailability?

Piperine can reduce the breakdown and efflux of some compounds by influencing drug-metabolizing enzymes and transporters. This may increase blood levels of certain co-administered nutrients or supplements, such as curcumin.

What are the main potential benefits of piperine?

Piperine is best known for supporting absorption (bioavailability). It also has antioxidant activity and is being studied for potential neuroprotective and cognitive-support roles.

What is a typical piperine dosage in supplements?

Common supplemental amounts are often in the 5–20 mg range per day. The best dose depends on the product and what it is paired with.

Are there safety concerns or interactions with piperine?

Because piperine can affect enzymes and transporters involved in drug metabolism, it may interact with some medications. People who take prescription drugs, are pregnant, or have medical conditions should consult a clinician before use.
