What Is DIOSMIN?
Diosmin is a semisynthetic flavonoid glycoside, often combined with hesperidin in a 9:1 ratio as micronized purified flavonoid fraction (MPFF). It works by improving venous tone, reducing capillary permeability, protecting endothelial function, and exerting anti-inflammatory effects primarily through modulation of inflammatory markers and oxidative stress pathways. Primarily used for chronic venous disease, hemorrhoids, and venous leg ulcers.

*Based on large scale analysis of publicly available user experiences
Users report generally positive experiences with diosmin, particularly for hemorrhoids, venous issues, and circulation improvement. Many report noticeable benefits for vascular health and erectile function, though effectiveness varies and high doses are often needed for hemorrhoid treatment.
DIOSMIN Benefits, Dosage & Side Effects
- Hemorrhoid Relief: Users report significant improvement in hemorrhoid symptoms, though often requiring higher than recommended doses (2-4g daily combined with hesperidin)
- Vascular/Circulation Benefits: Multiple users report improved erectile function, larger erection volume, and better overall circulation when combining with other vascular supplements
- Anti-inflammatory Action: Research and user reports indicate reduced inflammation in venous disease, with effects on inflammatory markers like IL-6, TNFα, and COX-2
- Wound Healing: Users taking for anal fissures and research on venous ulcers suggest accelerated healing, though individual results vary
- Chronic Venous Disease: Strong evidence from systematic reviews showing improvement in venous symptoms, signs, and quality of life across severity spectrum
- Hemorrhoid Treatment: Mixed user experiences - some find it ineffective at standard doses (450-500mg), many report needing 2-6g daily combined with hesperidin for noticeable results
- Dose-Response Relationship: Both research and users indicate higher doses (1-2g+) are more effective than standard recommendations, particularly for hemorrhoids and venous issues
- Synergistic Effects: Users report better results when combining with hesperidin, rutin, horse chestnut, and other flavonoids rather than using diosmin alone
- Standard Medical Dose: 450-500mg twice daily for chronic venous disease, often combined with hesperidin in 9:1 ratio (MPFF formulation)
- High-Dose Protocol for Hemorrhoids: Users report taking 2-4g daily (4-8 tablets of 450/50mg diosmin/hesperidin) for severe hemorrhoid symptoms
- Athletic Recovery: 100mg/kg body weight used in research for reducing DOMS; users experimenting with 500-1000mg for circulation and performance
- Duration: Users report needing several weeks to months for full effects on venous issues; acute hemorrhoid flares may require 3-5 day high-dose protocols
- Gastrointestinal Stress: Multiple users concerned about liver/kidney stress from high doses, particularly when combining multiple flavonoids and supplements
- Bleeding Risk: One case report of spontaneous intraventricular hemorrhage with prolonged use, users report blood-thinning properties when combined with other supplements
- Copper Depletion: Users report zinc-copper imbalance concerns when taking high-dose flavonoids alongside zinc supplementation
- Telomerase Inhibition: Some users concerned about hesperidin's strong telomerase inhibition, though unclear if this affects normal cells or primarily cancer cells
- Common Brands: quality brands widely mentioned but facing quality concerns after Chinese acquisition; users seeking alternatives with better quality control and COAs
- Formulations: Most commonly found as diosmin/hesperidin combination (450/50mg or 500/50mg), also available in MPFF (Daflon) branded formulation
- Sourcing Challenges: Users report difficulty finding reputable brands; quality brands offers rutin and horse chestnut but not pure diosmin, leading to multi-supplement stacking
