Grapefruit peel extract naringin
Product Introduction
Our grapefruit extract (naringin) is a natural active ingredient derived from the dried outer peel of high-quality grapefruit (*Citrus paradisi* Macf.). With naringin as its core active component, it is refined using advanced alcohol extraction, separation, chromatography, and crystallization processes. Produced without any artificial additives, it retains the full biological activity of citrus flavonoids.
The raw material is sourced from the peels of mature grapefruits grown in prime domestic citrus orchards. Each batch undergoes verification by a third-party testing agency prior to warehousing to ensure purity meets food-grade standards. The product appears as an off-white to pale yellow fine powder; the 98% HPLC high-purity grade passes through an 80-mesh sieve, offering flowability and solubility suitable for diverse downstream manufacturing applications.
Product benefits
Powerful Antioxidant & Anti-Aging Effect
Naringin is a natural high-activity flavonoid polyphenol, which can effectively clear free radicals in the human body and inhibit oxidative stress reaction. It reduces cell aging damage, delays skin and body aging, and has better antioxidant activity than ordinary citrus extracts, which is widely used in anti-aging product formulas.
Anti-Inflammatory & Protective Effects
The studies prove that naringin has significant anti-inflammatory, anti-apoptotic and tissue protective effects. It can protect the cardiovascular system, reduce vascular inflammation, regulate blood lipid and blood sugar levels, and has auxiliary protective effects on liver, kidney and nerve tissues, helping improve body metabolic health.
Assist Fat Metabolism & Digestion Improvement
Naringin can inhibit fat absorption in the intestine, accelerate body energy metabolism, and assist in healthy weight management. Meanwhile, it can promote gastrointestinal peristalsis, relieve bloating and constipation, and improve digestive system function, which is a safe natural ingredient for weight management health products.
Natural Antibacterial & Preservative Auxiliary
It has natural antibacterial activity against common bacteria and molds. It can be used as a natural preservative auxiliary in food and cosmetic products, reducing the use of chemical preservatives, and improving product safety and shelf stability.

Oral Care Products: Leverage antimicrobial properties when added to toothpaste and mouthwash formulations to inhibit *Streptococcus mutans* adhesion, aiding in cavity prevention.
Customer case study
We have long-term stable cooperative customers in more than 80 countries and regions such as Europe, America, Southeast Asia and Australia, providing customized raw material solutions for well-known brands in multiple industries:
North American Metabolic Supplement Brand – A California-based dietary supplement brand focused on metabolic health has sourced 98% purity naringin raw material from us since 2023 for use in its flagship blood-lipid-regulating capsules. To date, we have delivered 12 batches, maintaining purity variance within 0.3%—far below the industry standard of 1%. This consistency helped the product pass the FDA’s comprehensive compliance audit for dietary supplements, and the product achieved a 32% increase in repurchase rates following its launch.
EU Natural Skincare Brand – An organic skincare brand based in Berlin, Germany, selected our grapefruit extract for the formula of its oil-control serum designed for oily skin. We developed a customized specification featuring low microbial counts and minimal odor. After the product launched, the serum achieved a 94% positive rating for oil-control efficacy on local beauty platforms, prompting the brand to incorporate our raw material into three additional skincare product lines.
Domestic Functional Beverage Company – A leading domestic beverage group sourced our grapefruit extract (standardized to 60% flavonoids) for use in a newly launched citrus-flavored functional beverage. We collaborated with the client on stability testing and assisted in successfully completing the domestic regulatory filing for food additives; the beverage sold over one million bottles in its first month on the market.
