Psyllium

Glucose and metabolic health markers is closer to a research marker, so it should be read separately from a directly felt benefit.

The 63.9 score includes research signals from patient or disease contexts. General supplement evidence is not repeated enough, so the B tier remains conservative.

Representative tier calculated from paper evidence that passed the collection audit.

Paper IDs and full lists are private. Only study types and summaries are shown.

Key Evidence #1
Public scholarly dataCitation signal: 261
meta-analysis

Dietary fiber intake can obviously increase stool frequency in patients with constipation but it does not obviously improve stool consistency, treatment success, laxative use and painful defecation.

Key Evidence #2
Public scholarly dataCitation signal: 168
observational

It is found that psyllium supplementation increased stool water and this was associated with significant changes in microbiota, most marked in constipated patients.

Key Evidence #3
Public scholarly dataCitation signal: 167
observational

It is found that the dietary fibers or probiotics may relieve hard stool, with intervention-specific changes in gut microbiota relevant to constipation relief, in 250 adults with functional constipation.
