Product Introduction
Premium Citrus Bioflavonoid Complex – Professional Plant Extract Manufacturer
Kang Biotech provides Citrus Bioflavonoid Complex from managed plantations in Hunan Province, China, sourced from approximately 20,000,000 m² of regulated cultivation. Standardized formulations with 10%-98% HPLC-verified total flavonoids, including 98% pure Hesperidin (CAS 520-26-3), are available from our 11 years of production and 20 years of citrus extraction technology experience. Our 33,000 m² ISO 9001, ISO 22000, HACCP, Halal, and Kosher-certified facility runs 9 modern manufacturing lines to ensure batch-to-batch consistency and meet worldwide food, nutraceutical, and pharmaceutical standards. We have available stock and accept 1 kilogram OEM/ODM orders.
What Makes Our Citrus Bioflavonoid Complex Different?
Our product is a concentrated phytochemical extract from Citrus sinensis, Aurantium, and other citrus species. It retains Hesperidin, Naringin, Eriocitrin, and Neohesperidin's synergistic ratio.
This complex solves major industry issues. Bioavailability is poor for isolated flavonoids. The natural chemical ratios in our formulation improve systemic absorption. In immune and vascular health products, it stabilizes Ascorbic Acid, avoiding fast oxidation.
Citrus-scented bright yellow to gray-brown fine powder is the extract. It dissolves and mixes well with drinks and solid dosage forms.

Versatile Applications Across Industries
Dietary Supplements for Wellness Support
Citrus Bioflavonoid Complex is a key element in premium supplements. Combining with Vitamin C boosts capillary permeability and antioxidants. Bioflavonoids synergize to improve health absorption and efficacy.
Sport Nutrition and Performance
The compound promotes microcirculation and works well under high oxidative stress in B2B pre-workout and recovery formulations. This steady profile makes it suitable for solutions targeting energetic people needing nutritional assistance during severe physical exercise.
Food and Beverages with Function
The complex is a liquid antioxidant with clear label. Its chemical stability preserves fruit juices and functional waters' organoleptic characteristics and color. It preserves naturally without affecting flavor or appearance.
Rigorous Quality Control and Testing Protocols
Quality control starts with our regulated citrus orchards and continues throughout production. Products are tested to international standards.
Active Component Analysis
We measure Hesperidin, Naringin, and other flavonoids using HPLC. This approach removes UV-related non-specific results and verifies synthetic adulterants are absent.
Tests for safety and purity
Our GC-MS/MS screening for over 400 pesticide residues meets EU and USDA organic standards. Heavy metal analysis (ICP-MS) reveals Pb <0.5 ppm, Cd <0.5 ppm, Hg <0.1 ppm, and As <1.0 ppm
Microbe Profiling
All batches are tested according to USP <61> and <62> standards. We ensure a total aerobic microbial count of <1,000 CFU/g and no Salmonella, E. Coli, or Staphylococcus aureus before discharge.
Botanical Verification
TLC and HPTLC fingerprinting identify botanicals and avoid non-citrus fillers and synthetic substances. Safety of extraction solvents is verified by residue testing.
