Oral flavonoid blends, usually built on diosmin and hesperidin, for bleeding and pain from hemorrhoids. The pharmaceutical-grade version (micronized purified flavonoid fraction) has real trial support; generic supplement blends are not the same product.

What the science says

  • Symptom relief in hemorrhoidal disease Moderate evidence

    A systematic review and meta-analysis of micronized purified flavonoid fraction found reduced bleeding, pain and itching, and lower recurrence, versus control. Many of the trials were industry-sponsored and of moderate quality.

  • Recovery after hemorrhoid surgery Moderate evidence

    A systematic review and meta-analysis of flavonoids and post-haemorrhoidectomy recovery reported less post-operative bleeding and pain. Effect sizes were modest and heterogeneity between trials was substantial.

Dosage & safety

Studied doseThe studied regimen is 1000–3000 mg per day of micronized diosmin/hesperidin: often 3000 mg daily for the first four days of an acute episode, then 2000 mg for three days, then 1000 mg daily. Supplement blends frequently contain unmicronized diosmin at lower doses.
SafetyUsually well tolerated; stomach upset and diarrhoea are the main effects. Not established in pregnancy or breastfeeding. Rectal bleeding needs medical assessment first, since it can indicate colorectal disease rather than hemorrhoids.

How to take it

TimingSplit the daily amount into two or three doses across the day.
With food?With meals, which reduces the stomach upset and diarrhoea that are the main complaints.
Worth knowingThe high loading dose is only for the first few days of an acute flare; fibre, fluids and not straining do more for hemorrhoids long-term than any flavonoid.

Frequently asked questions

Do diosmin and hesperidin supplements work for hemorrhoids?

The micronized purified flavonoid fraction of diosmin and hesperidin has moderate evidence: meta-analyses found less bleeding, pain and itching and lower recurrence versus control, though many trials were industry-sponsored. Generic hemorrhoid support blends often use unmicronized diosmin at lower doses and are not the same product that was tested.

How much diosmin should I take for a hemorrhoid flare?

The studied regimen for micronized diosmin/hesperidin is often 3000 mg daily for the first four days of an acute episode, then 2000 mg for three days, then 1000 mg daily. Split the daily amount into two or three doses with meals.

Do hemorrhoid flavonoid supplements help after hemorrhoid surgery?

A meta-analysis of flavonoids after haemorrhoidectomy reported less post-operative bleeding and pain, which is moderate-grade evidence. The effect sizes were modest and the trials varied considerably, so hemorrhoid flavonoid formulas are an add-on, not a substitute for post-operative care.

What are the side effects of hemorrhoid support supplements?

Hemorrhoid flavonoid formulas are usually well tolerated, with stomach upset and diarrhoea as the main effects, which taking them with meals reduces. Safety in pregnancy and breastfeeding is not established, and rectal bleeding should be medically assessed first because it can signal colorectal disease.
