THE SHORT ANSWER
Yes. This is actually the standard clinical formulation for venous insufficiency. Diosmin and hesperidin are citrus-derived flavonoids commercially combined as micronised purified flavonoid fraction (MPFF), sold as Daflon in Europe. This combination is a first-line pharmaceutical treatment for chronic venous disease, haemorrhoids, and lymphoedema in many countries, with robust clinical trial support.
How They Support Vascular Health
Diosmin (90% of the MPFF formulation) and hesperidin (10%) work together to improve venous tone, reduce capillary permeability, and decrease inflammation in the vascular walls. Diosmin increases venous wall tension and reduces venous capacitance, essentially making weak, floppy veins more taut and functional. It also inhibits leukocyte adhesion and activation at the venous valve level, reducing the inflammatory cascade that drives chronic venous disease progression.
Hesperidin contributes additional anti-inflammatory and antioxidant activity. It inhibits prostaglandin and thromboxane synthesis, reduces capillary permeability (which decreases oedema), and protects the endothelial lining from oxidative damage. The micronised formulation (particle size below 2 micrometres) is critical: it increases oral bioavailability by approximately 50% compared to non-micronised versions.
Clinical Evidence
The evidence base for MPFF is substantial. A Cochrane review and multiple meta-analyses have confirmed that MPFF significantly reduces symptoms of chronic venous insufficiency: leg heaviness, pain, swelling, cramps, and restless legs. It also accelerates healing of venous leg ulcers when used alongside compression therapy. For haemorrhoids, MPFF reduces bleeding, pain, and discharge during acute episodes and reduces recurrence when used as maintenance therapy. The RELIEF study, involving over 5,000 patients across 23 countries, demonstrated significant symptom improvement with MPFF treatment.
Dosing and Timing
Standard MPFF dose: 1,000mg daily (900mg diosmin + 100mg hesperidin) as a single dose or split into two 500mg doses with meals. This is the dose used in most clinical trials.
Acute haemorrhoids: 3,000mg daily for 4 days, then 2,000mg for 3 days, then maintenance at 1,000mg daily.
Formulation: Insist on micronised formulations. Non-micronised diosmin has dramatically lower bioavailability. Daflon (Servier) is the reference pharmaceutical product. Generic micronised versions are also available.
Duration: For chronic venous disease, this is typically used as ongoing maintenance therapy. Symptom improvement begins within 2-4 weeks, with maximum benefit at 2-3 months.
Safety Considerations
Excellent safety profile: MPFF has been used clinically for decades with minimal reported adverse effects. Mild GI symptoms (nausea, abdominal discomfort) occur in approximately 5% of patients and are usually transient.
Pregnancy: MPFF has been used in clinical trials during pregnancy (second and third trimester) for haemorrhoid treatment without reported adverse effects. However, first trimester use lacks sufficient data. Consult your obstetrician.
Drug interactions: Hesperidin may inhibit certain CYP enzymes at very high doses, but at standard MPFF doses, clinically significant drug interactions are rare. Theoretically, it may enhance the effects of anticoagulants, so monitor if relevant.
Anticoagulants: While not a strong interaction, inform your prescriber if you take warfarin or NOACs, as flavonoids can have mild effects on platelet function.
An Educational Perspective: This is one of the few supplement combinations that is actually a recognised pharmaceutical treatment in Europe. I prescribe MPFF for individuals with chronic venous insufficiency (heavy legs, varicose veins, ankle oedema) and as adjunctive treatment for haemorrhoids. The evidence is strong, the safety profile is excellent, and in my experience, patients notice meaningful symptom relief within 3-4 weeks. For anyone with regular leg heaviness, evening ankle swelling, or spider veins, MPFF at 1,000mg daily alongside regular walking and compression stockings is the evidence-based approach.
