BioPerine
Also known as: piperine, black pepper extract, Piper nigrum extract
Effective Dosage
2.5–10 mg daily (as bioavailability enhancer, based on study doses)
What the Science Says
BioPerine is a patented extract of black pepper standardized to piperine, the compound responsible for pepper's pungency. It is used almost exclusively as a bioavailability enhancer — meaning it is added to supplements to help the body absorb other ingredients more effectively, not as an active ingredient on its own. In the studies provided, it appeared alongside curcumin, Nigella sativa oil, and multi-ingredient sports formulas at doses of 2.5–10 mg, always in a supporting role.
What It Doesn't Do
BioPerine itself is not shown to improve strength, endurance, or athletic performance — the sports supplement studies it appeared in showed no benefit over placebo. It has no proven standalone health benefits from the provided research. It won't fight cancer, reduce cholesterol, or relieve allergies on its own — those effects came from the other ingredients it was paired with. Don't assume a product works better just because it contains BioPerine.
Evidence-Based Benefits
BioPerine is a standardized extract of black pepper that contains piperine, which has been shown to enhance the bioavailability of various nutrients and compounds, including curcumin and certain vitamins. Some clinical trials suggest that it may improve absorption and effectiveness of these substances.

Absorption & Bioavailability
Unknown for BioPerine itself — it is intended to enhance the absorption of other compounds, not to be absorbed for its own effects. No standalone bioavailability data provided in the studies.
Red Flags to Watch For
- BioPerine is almost always a minor ingredient used to justify premium pricing — the real active ingredient is something else entirely
- Piperine can interact with certain medications by inhibiting drug-metabolizing enzymes (e.g., CYP3A4), potentially raising blood levels of drugs to unsafe levels — consult a doctor if you take prescription medications
- None of the provided studies tested BioPerine alone, so any claimed standalone benefits are unsupported by this evidence base
- Appearing in 1,000+ registered supplement products does not mean it is effective — widespread use reflects marketing trends, not proven efficacy
