Diosmin + Hesperidin (MPFF) 1,000mg Cuts Leg Edema -38%, Pain -42% in 12-Week CVI RCT
The standard MPFF (micronized purified flavonoid fraction, diosmin 900mg + hesperidin 100mg) at 1,000mg/day for 12 weeks reduced leg edema -38%, heaviness·pain -42%, night cramps -32%, leg circumference -2.8cm, raised venous tone +25% in 250 chronic venous insufficiency (CVI) patients, according to 2025 data in Phlebology (SAGE). New RCT validation for the European·Latin American venous insufficiency standard prescription with 30+ year clinical use.
The trial enrolled 250 CVI (CEAP C1~C4) patients across 12 weeks. Results: leg edema -38% (water displacement), heaviness·pain·burning -42%, night cramps -32%, itching·skin changes -28%, leg circumference -2.8cm (evening measurement), venous tone (air plethysmography) +25%, quality of life (CIVIQ) +35%. Adverse events: minor (mild gastric discomfort 6%).
Chronic venous insufficiency (CVI) — common missed diagnosis
What it is:
- Vein valve weakness → blood reflux → leg vein pressure ↑
- Failure of return blood flow from legs to heart
- CEAP classification: C0 (symptoms only)~C6 (ulcers)
- 50
60% of women, 4050% of men experience it in lifetime
Symptoms:
- Leg edema (especially evening·after long standing)
- Heaviness·burning·pain
- Night leg cramps
- Spider veins (C1) → varicose veins (C2) → skin changes (C4) → ulcers (C6)
- Itching·skin pigmentation
Risk factors:
- Female, pregnancy, hormones (oral contraceptives·HRT)
- 50+, obesity, family history
- Long standing·sitting (hairdressers·teachers·office workers)
- Sedentary·chronic constipation
MPFF — venous insufficiency standard matrix
Diosmin 90% + Hesperidin 10%:
- Citrus flavonoids (orange·lemon peel)
- Micronized form — particle size ↓ → absorption ↑
- European·Latin American CVI prescription drug (Daflon·Detralex)
Multi-target mechanisms:
1. Venous tone enhancement:
- Vein smooth muscle norepinephrine response ↑
- Vein diameter ↓ → pressure ↓
- Valve function support
2. Lymphatic drainage acceleration:
- Lymphatic vessel contraction frequency ↑
- Core mechanism for leg edema reduction
- Anti-edema effect
3. Capillary protection:
- Capillary permeability ↓
- Microbleeding·skin change prevention
- Leukocyte-endothelium interaction ↓
4. Anti-inflammatory:
- Prostaglandins·leukotrienes ↓
- Vein inflammation·thrombosis risk ↓
- CRP reduction
5. Antioxidant:
- Oxidized LDL ↓
- Endothelial function support
- Oxidative stress ↓
Clinical data
- Phlebology 2025 RCT 250 patients 12 weeks: edema -38%, pain -42%
- 2024 meta-analysis: 30 years MPFF data, 25 trial meta-consistent efficacy
- 2023 trial: pregnancy CVI 100 patients 8 weeks edema -32%
- 2022 trial: venous ulcer (C6) adjunct 80 patients 6 months healing +35%

Korean market context
Supplements·prescription:
- MPFF tablets (diosmin 900mg + hesperidin 100mg) 60 tabs: 30,000~60,000 KRW
- Diosmin standalone 500mg 60 caps: 25,000~50,000 KRW
- OTC (not prescription-only) available at pharmacies
- Matrix (MPFF + horse chestnut + butcher’s broom): 50,000~100,000 KRW
Adjunct — compression stockings:
- Medical compression stockings (15~30mmHg)
- MPFF + compression matrix superior to single
- Long-standing jobs·travel
Diet — natural flavonoids:
- Citrus (orange·lemon·grapefruit) peel·flesh
- Buckwheat (rich in rutin)
- Berries (blueberry·blackberry)
- Onion·green tea
Lifestyle:
- Leg elevation (15 min × 3/day)
- Calf exercise (vein pump)
- Adequate hydration
- Constipation prevention
- Avoid salty foods (worsens edema)
Cautions
- Pregnancy·lactation: MPFF safety data (European prescription use). Physician assessment
- Liver enzyme impact: chronic use liver function testing recommended
- Gastric discomfort: micronized form improves, some mild gastric burden
- Anticoagulant warfarin·DOAC: bleeding risk. Physician assessment
- MAO inhibitors: some interactions possible. Physician assessment
- 3~6 month cumulative assessment: venous tone recovery is cumulative
- Inappropriate for short-term edema (injury·exercise): CVI chronic target
- C5~C6 ulcers: MPFF alone insufficient, comprehensive medical treatment
Synergy matrix
- MPFF (diosmin + hesperidin): CVI first-line matrix
- + Horse chestnut extract (aescin): vein connective tissue support
- + Butcher’s broom (Ruscus): enhanced venous tone
- + Grape seed OPC·pycnogenol: microcirculation matrix
- + Gotu kola (Centella): vein·lymph support
- + Compression stockings + exercise: matrix adjunct
