About Citrus Bioflavonoids
Citrus bioflavonoids are a group of polyphenolic compounds found in citrus fruits, primarily hesperidin, naringin, rutin, and diosmin. Often included in vitamin C supplements as co-factors. The most clinically studied components are hesperidin (cardiovascular, blood pressure) and diosmin (venous insufficiency — Daflon 500mg is a prescription product in Europe). As a generic 'bioflavonoid complex,' the composition varies widely between products and is rarely standardized, making dosing comparisons difficult. Individual components (hesperidin, rutin) have their own evidence base and are scored separately when listed.

How much Citrus Bioflavonoids to take
Clinical studies typically use 250–1000 mg of Citrus Bioflavonoids. Typical supplement range 250–1000 mg/day. Often a mix of hesperidin, naringin, rutin, and other flavanones. Standardized extracts (e.g. Diosmin/Hesperidin 90:10) are better studied.

Clinical evidence
Limited clinical evidence. Mixed flavonoid complex; individual components (hesperidin, diosmin) have moderate evidence, but generic complexes are poorly standardized
