Psyllium Husk

A soluble fiber studied for cholesterol and digestive regularity.

Evidence category: Systematic review. This describes the source category, not approval or certainty.

Regulatory statement in source: Not separately recorded; do not infer approval from the evidence category.

Psyllium is a soluble, viscous fiber derived from the husk of Plantago ovata seeds, commonly used as a bulk-forming laxative and fiber supplement. Randomized controlled trials have examined its effects on chronic constipation and on blood lipid levels including LDL cholesterol. Pooled meta-analyses of these trials report consistent improvements in stool frequency for constipation and reductions in LDL and non-HDL cholesterol compared with placebo.

Benefits reported in the imported source

  • Randomized trials consistently show reductions in LDL and non-HDL cholesterol compared with control diets
  • Well-supported as a bulk-forming fiber for relieving chronic constipation

Risks and limits

  • Mild gastrointestinal effects such as bloating and gas are commonly reported, especially when starting
  • Product adulteration with cheaper fillers such as amaranth or wheat bran has been documented in the psyllium supplement market

Source bottom line: Trial evidence solidly supports psyllium for improving cholesterol markers and relieving constipation, making it one of the better-evidenced fiber supplements on the market.

Uncertainty: Reference information only. Not medical advice.
