Last updated: June 2026 · Reviewed by the FactoWiki Editorial Team for clarity and source accuracy
Quick summary
Naringenin is a citrus flavonoid (notably in grapefruit) studied for metabolism. Evidence is largely preclinical, and grapefruit's drug interactions are a relevant caution.
What is Naringenin?
Naringenin is a flavonoid found in citrus fruits, especially grapefruit, sold as an antioxidant and metabolic supplement.
What Naringenin is commonly used for
In supplements, Naringenin is most often included for weight & metabolism, blood sugar & metabolism support. It is used as nutritional support, not as a treatment for any medical condition — the distinction matters, because the claims on a sales page are often stronger than the evidence allows.
How Naringenin works
Naringenin has antioxidant and anti-inflammatory activity and, in laboratory studies, effects on fat and sugar metabolism, the basis for its metabolic marketing.
What the evidence says
Here's an honest snapshot of what published research suggests about Naringenin — including where the evidence is limited.
- Most naringenin evidence is from laboratory and animal research; human clinical data are limited, so its metabolic benefits are unproven.
- Study quality and doses vary, and a result seen in research doesn't guarantee the same for any individual — use the sources below to check the current evidence on Naringenin rather than relying on marketing claims.
Typical dosage used in studies
Supplement doses vary; dietary intake comes from citrus fruits. This is general information from research, not a personal recommendation or a dosing instruction.
Side effects and safety
Naringenin is generally well tolerated from food; like other grapefruit compounds it may affect the enzymes that metabolise many medications, so caution applies if you take prescription drugs. As with any supplement, it's sensible to introduce Naringenin on its own, use a trusted brand, and stop if you notice any reaction.
Medication interactions and who should avoid Naringenin
Medication & safety check
Naringenin can interact with certain medications or health conditions in ways that aren't always obvious. If you take any regular medication, are pregnant or breastfeeding, or manage a health condition, confirm Naringenin is appropriate for you before starting.
This is general information, not personal medical advice. If you take any medication, are pregnant or breastfeeding, or have a health condition, confirm it's safe to use Naringenin with your doctor or pharmacist first.
