Psyllium Fiber Supplement

Reviewed by the Nimbera editorial team · Last updated May 2026

Moesgaard et al. 1982 double-blind RCT (Dis Colon Rectum, PMID 6284457) - psyllium-based fiber supplement (Vi-Siblin) significantly reduced bleeding and pain in hemorrhoid patients versus placebo.$10-$20 per month.

How to use

Take 5-10 g of psyllium husk powder (e.g. Metamucil) mixed in a full glass of water (250 ml) once or twice daily. Take at the same time each day and always with plenty of fluid to prevent choking or obstruction. Allow 1-3 days to notice softer stools.

How it works

Psyllium is a soluble fiber that absorbs water and forms a gel in the gut, softening stool and increasing bulk. Softer, well-formed stools reduce straining during defecation, which is the primary mechanical driver of hemorrhoidal engorgement, prolapse, and trauma.

Where to buy

Pharmacies and supermarkets (Metamucil, Fybogel, store-brand psyllium husk). Available as powder, capsule, or wafer forms.

Typical cost: $10-$20 per month.

Safety notes

Always take with a full glass of water - dry psyllium can swell in the throat and cause choking. Start with a low dose and increase gradually to avoid gas and bloating. Not suitable for people with difficulty swallowing or bowel obstruction. May slow absorption of some medications - take 1-2 hours apart.
