Partially Hydrolyzed Guar Gum (PHGG) and Psyllium Husk

Each entry’s own grades, side by side. A grade says how strong the evidence is for one outcome — it does not rank one entry over the other.

Compound or practice

Partially Hydrolyzed Guar Gum (PHGG)

A gentle, well-tolerated soluble fiber that helps both constipation and diarrhea — the low-FODMAP-friendly fiber for IBS.

Grade B2 graded outcomesrevised Jul 10, 2026

A structured monograph in Prometheus's bundled library. Its grades are the monograph's own reading of the evidence, not a peer-reviewed review.

Compound or practice

Psyllium Husk

The most boring A-grade on the shelf: a soluble fiber that improves regularity, LDL, and glucose — and binds your medications.

Grade A3 graded outcomesrevised Jul 10, 2026

A structured monograph in Prometheus's bundled library. Its grades are the monograph's own reading of the evidence, not a peer-reviewed review.

Swap the two

Graded in both

Outcomes are matched by name. Two entries can describe the same outcome in different words, so one listed further down may still be graded in the other.

No outcome has the same name in both entries. They may still overlap under different wording — read the two lists below.
