/ Naringin / Citrus Extract is a botanical extract derived from Pomelo/grapefruit peel, standardized to Naringin. With CAS registry number 10236-47-2, this ingredient belongs to the Novel & Emerging Ingredients category of weight management actives. Naringin improves lipid metabolism + antioxidant activity. Also modulates drug metabolism (CYP3A4 inhibition — caution with medications). Grapefruit naringin is the reason grapefruit interacts with many drugs — this is mechanistic, not a safety failure. As a B2B manufacturer, Shaanxi Baisifu Biological Engineering Co., Ltd. supplies Naringin / Citrus Extract in bulk quantities with full Certificate of Analysis (COA), ensuring consistent Naringin content and regulatory compliance for dietary supplement, functional food, and nutraceutical applications.
Standard specifications for Naringin / Citrus Extract bulk supply from Baisifu:
Naringin improves lipid metabolism + antioxidant activity. Also modulates drug metabolism (CYP3A4 inhibition — caution with medications). Grapefruit naringin is the reason grapefruit interacts with many drugs — this is mechanistic, not a safety failure.
Level III. Lipid metabolism improvement demonstrated in preclinical studies. Human weight loss data limited.
⚠CYP3A4 inhibition → increases blood levels of many drugs (statins, calcium channel blockers, immunosuppressants). This is naringin's known property — requires clear labeling. Not for individuals on CYP3A4-metabolized medications.

• Naringin content verification (HPLC/UV)
• Heavy metals, microbial, moisture compliance
• Pesticide residue testing (where applicable)
• Stability data and shelf life confirmation Available forms: powder extract, oil-based softgel fill, microencapsulated powder
Minimum order: 1 kg (sample quantities available)
Lead time: 7–15 business days
Packaging: 25 kg/drum, double-layer PE bag + fiber drum, nitrogen flush available
Q1: Why does grapefruit interact with medications?
Naringin inhibits CYP3A4 enzyme in liver/intestine → drugs metabolized by CYP3A4 reach higher blood levels → potential toxicity. This is naringin's pharmacological property, not a contaminant. Requires clear labeling on supplement products.
For complementary weight management formulations, consider combining Naringin / Citrus Extract with: Hesperidin, Nobiletin, Quercetin, Berberine. Multi-ingredient stacks targeting different mechanisms (lipase inhibition, AMPK activation, thermogenesis, appetite suppression) produce synergistic effects superior to single-ingredient products.
