Raw Material Display & Product Portfolio
Explore our premium raw materials and discover customizable API options tailored to your specific formulation needs.
Diosmin Ingredient
Our ultra-pure Diosmin is a flagship active pharmaceutical ingredient (API) and dietary supplement standard. Extracted from natural citrus sources, it serves as the foundational active ingredient in vascular health formulations, targeting venous tone, lymphatic drainage, and capillary resistance. We offer micronized grades to optimize absorption and efficacy in leg support and circulation products.
Citrus Bioflavonoids
As an industry-leading citrus bioflavonoid supplier, we extract complex mixtures of natural citrus flavonoids (including Hesperidin, Naringin, and Neohesperidin) from immature citrus fruits. These compounds act as potent antioxidants, protecting cells from oxidative stress and supporting the structural integrity of the cardiovascular system.
Custom Formulations
Our contract manufacturing services enable supplement brands to develop proprietary blends. By combining the diosmin ingredient with hesperidin or custom sports nutrition matrices, we assist health food companies in creating high-performance, clean-label products tailored to strict European and global regulatory standards.

Targeted Leg Support & Circulation
Our specialized flavonoids play a critical role in mitigating the symptoms of chronic venous insufficiency (CVI). Formulators rely on our high-quality diosmin ingredient to construct products that alleviate heavy legs, reduce swelling, and promote healthy microcirculation. By strengthening capillary walls and improving venous tone, our plant extracts serve as the active benchmark for premium vascular health supplements worldwide.
For sports nutrition brands, citrus bioflavonoids offer dual benefits: enhancing blood flow to active muscles and accelerating recovery times by combatting exercise-induced oxidative damage. Partnering with a dedicated flavonoid manufacturer ensures your brand receives consistent, active-rich materials that deliver real results.
Antioxidant Properties & Clean Label Appeal
The demand for clean-label, natural-origin ingredients is reshaping the European health food market. Our citrus extracts are processed using advanced green extraction techniques, eliminating harmful solvents and chemical additives. The resulting bioflavonoids are rich in active polyphenols, which provide comprehensive cellular defense against free radicals.
As a specialized citrus bioflavonoid supplier, we ensure that our ingredients are free from GMOs, allergens, and artificial carriers. This enables your brand to market products with clean, transparent ingredient lists that resonate with health-conscious consumers seeking pure, plant-based nutrition.
