Psyllium 10 g/day added to a weight-loss diet and physical-activity advice,
does it really help with Improved ALT and FibroScan liver-function measures over ten weeks in adults with overweight or obesity and MASLD?
research showsGrade C. In a ten-week trial randomizing 80 adults to psyllium 10 g/day or ground wheat 10 g/day while both groups received weight-loss and activity advice, ALT, P=.006, and a FibroScan fibrosis score, P=.001, favored psyllium, while AST was null, P=.98. Exact between-group effect sizes, confidence intervals, and the prespecified primary hierarchy were not verified, so this does not establish reduced MRI liver fat or disease modification.
ads claimSaying that psyllium removes liver fat adds an MRI or histologic outcome the study did not measure. The evidence concerns selected enzymes and an elastography-related measure.
Useful facts when choosing a product
- The trial used psyllium 10 g/day.
- Control participants received ground wheat and the same lifestyle advice.
- A FibroScan measure is not the same as MRI liver fat.
What the research actually shows
Eighty adults with overweight or obesity and MASLD were block-randomized to psyllium or ground wheat, both 10 g/day, and 78 completed ten weeks. Both arms received a weight-loss diet and physical-activity advice. Adjusted ALT and the FibroScan score favored psyllium, while AST had P=.98.
Why this is classified as C (50)
Selected surrogate signals are offset by unclear effect sizes and prespecification, completer-focused analysis, small sample, and ten-week duration, giving C with 50 points.
Counterpoint. Psyllium requires adequate fluid and can pose specific risks in dysphagia or intestinal narrowing.

| Endpoint | S | Surrogate marker - laboratory or imaging measures |
| Replication | R1 | Single confirmatory trial |
| Independence | I2 | Decisive evidence is publicly or non-profit funded |
| Effect size | EX | The clinical size of the effect could not be judged |
The scoring table and the verdict agree (C).
Sub-claim grades by effect
This ingredient is marketed for several effects. A single overall grade blends strong and weak claims together, so each effect is graded separately here. The overall grade reflects the strongest disconfirming or core claim.
| Effect (sub-claim) | Grade | Basis |
|---|---|---|
| Improved ALT and FibroScan measures over ten weeks | C | Some between-group P values were positive, but effect size and prespecified hierarchy are unclear. |
| Reduced MRI-measured liver fat | ? | This was not measured. |
