A flavonoid compound derived from citrus fruits, often chemically converted (hesperidin methylated to diosmin) and used in a micronized form in venous health supplements.

Why it’s used

Taken to support vein health, particularly for symptoms associated with chronic venous insufficiency such as leg heaviness or swelling.

What the evidence is for

easing symptoms of chronic venous insufficiency.

What the evidence says

A 2026 systematic review and meta-analysis pooled five studies (411 patients, mostly women, mean age 40) testing micronized purified flavonoid fraction (MPFF, a mixture dominated by diosmin with other citrus flavonoids) at 1000 mg daily in early-stage chronic venous disease (C0s-C1). It reported reductions in self-rated pain and heaviness scores and improved quality-of-life scores compared with baseline/control. The authors note two of the five studies had high risk of bias, heterogeneity across studies was frequently high, and several authors are employees of or paid consultants to the product's manufacturer, limiting confidence in the magnitude and consistency of effect.

Context

Most positive trials use a combined micronized diosmin-hesperidin product rather than diosmin alone, and study populations are typically adults with diagnosed venous disorders rather than the general population.
