Top outcomes
1000mg MPFF daily (900mg diosmin + 100mg hesperidin); acute hemorrhoid protocols use higher short-term doses (a typical label dose, no cited trial states the dose it used)
With meals
MPFF (micronized diosmin + hesperidin)
Supplements commonly provide 99 mg per serving, and food provides more (no cited trial states the dose it used). No upper limit is established, so no maximum is stored. That is not a statement that larger amounts are safe.
