What it does: Naringin acts as a potent antioxidant, helping to neutralize free radicals, and is known to affect liver enzymes (notably CYP3A4), which play a key role in metabolizing medications and nutrients.
How it is used: It is most often used in supplements for metabolic support, antioxidant effects, and to increase the absorption and action of other nutrients by impacting liver enzyme activity.
Natural sources and supplement forms: Grapefruit peel is the main dietary source, with much smaller amounts found in other citrus fruits. Naringin is available as grapefruit extract or as an isolated compound, typically in capsules or powders.
Why it appears in supplement formulas: Supplement makers include naringin to support antioxidant status, metabolic processes, and boost the bioavailability of other active ingredients in blends, especially where interactions with liver enzymes are desired.
What to know before use: Naringin can alter the breakdown of many medications, so consult a healthcare provider before use if you are taking prescription drugs.
Interesting Fact
Naringin: The Compound Behind Grapefruit's Signature Bitterness
Naringin is a natural flavonoid found mainly in grapefruit and gives the fruit its distinct bitter taste. This citrus compound is commonly included in supplements for its role as an antioxidant. Interestingly, naringin can influence how the body processes certain nutrients and other compounds, which is one reason it's sometimes paired with other ingredients in supplement blends.
