What the rows share
From the rowsThe best-graded row, grade B, is a meta-analysis of 962 people (2024) and found an improvement.
The rows run from 354 to 962 people, published from 2023 to 2024: 2 pooled reviews and 0 single studies.
The rows
1 improved · 1 mixed- BGrade BFasting blood sugar, HbA1c and insulin resistance · Improved
Meta-analysis · n 962 · 2024 · Adults in 19 RCTs
Varied; subgroups below and above 10 g/day · Varied; fasting blood sugar not significant in trials shorter than 50 days
Fasting blood sugar fell by 6.89 mg/dL, HbA1c by 0.75 and HOMA-IR by 1.17 versus placebo; insulin did not change significantly. HbA1c was not significantly lower with less than 10 g/day.
- CGrade CBody weight, BMI and waist size · Mixed
Meta-analysis · n 354 · 2023 · Participants with overweight or obesity in 6 RCTs of at least 2 months
Mean 10.8 g/day · Mean 4.8 months
Body weight fell by 2.1 kg, BMI by 0.8 and waist by 2.2 cm. A 2020 meta-analysis of 22 RCTs found no significant change in weight, BMI or waist, and a 2025 analysis of 27 RCTs reported weight 3.57 kg higher with psyllium, so the overall picture is conflicting.
