Explore our core pharmacological-grade and dietary supplement active ingredients, sourced and processed under strict global guidelines.
Lemon Bioflavonoids refer to a complex of bioactive polyphenolic compounds extracted from the peel, pulp, and juice of the Citrus limon fruit. The major constituents include Eriocitrin, Hesperidin, Naringin, and Rutin. Known for their structural characteristics as flavonoids, they possess strong antioxidant capacities that scavenge reactive oxygen species (ROS) and block lipid peroxidation pathways.
Eriocitrin is particularly prominent in lemon extract compared to other citrus species. It is a highly soluble eriodictyol glycoside known for its clinical efficacy in reducing oxidative stress associated with metabolic syndromes and supporting healthy blood glucose levels. When sourced in bulk, these compounds are standardized to specific percentages (ranging from 10% to 90% total bioflavonoids) via high-performance liquid chromatography (HPLC) or UV-Vis spectrophotometry to ensure efficacy in functional formulations.
Why international dietary supplement and pharmaceutical buyers choose Chinese exporters for global raw materials sourcing.
China is home to vast agricultural citrus belts (such as the Anyue region in Sichuan, which accounts for over 80% of China's lemon cultivation). This direct integration of farming and industrial processing guarantees stable, year-round access to fresh lemon peels, shielding global buyers from price volatility.
Our extraction facilities rely on state-of-the-art countercurrent extraction lines, multi-stage macroporous resin purification, and spray drying systems. This industrial infrastructure enables high-throughput processing while maintaining batch-to-batch consistency and minimizing thermal degradation of flavonoids.
By complying with USP, EP, and ChP monographs, Chinese manufacturing plants meet global market demands. We implement comprehensive testing protocols for heavy metal limits (Pb, As, Hg, Cd), pesticide residue screens (over 400 components via LC-MS/MS), and residual solvent control.

Providing functional bioflavonoid formulations across global health and wellness applications.
Our bioflavonoids strengthen capillaries, enhance venous tone, and optimize blood micro-circulation. They are typically combined with Vitamin C to generate highly synergistic antioxidant formulations (such as Citrus Bioflavonoid tablets and capsules).
Using proprietary debittering processes, our water-soluble lemon bioflavonoid complexes provide stable citrus notes without adding harsh bitterness. Perfect for sports drinks, energy formulas, dry mixes, and antioxidant teas.
Eriocitrin acts as a natural skin-brightening agent. It limits UV-induced intracellular oxidative stress and inhibits melanin biosynthesis pathways. Additionally, it targets AGE (advanced glycation end-product) formation to protect collagen integrity.
