Effect of yogurt containing polydextrose, Lactobacillus acidophilus NCFM and Bifidobacterium lactis HN019: a randomized, double-blind, controlled study in chronic constipation
Open accessAbstract
BACKGROUND: Constipation is a frequent complaint and the combination of a prebiotic and probiotics could have a potentially synergic effect on the intestinal transit. The present study therefore aims to investigate the combination of polydextrose (Litesse), L. acidophilus NCFM® and B. lactis HN019 in a yogurt on intestinal transit in subjects who suffer from constipation. METHODS: Patients with constipation were randomly divided into two groups, Control Group (CG) and Treatment Group (TG), and had to eat 180 ml of unflavored yogurt every morning for 14 days. Those in the CG received only yogurt, while the TG received yogurt containing polydextrose, L. acidophilus NCFM (ATCC 700396) and B. lactis HN019 (AGAL NM97/09513). RESULTS: Favourable clinical response was assessed since Agachan score had a significant reduction at the end of the study in both groups and tended to be better in the TG. The subjects in the treatment group also had a shorter transit time at the end of the intervention compared to the control group (p = 0.01). CONCLUSION: The product containing yogurt with polydextrose, B. lactis HN019 and L. acidophilus NCFM® significantly shortened colonic transit time after two weeks in the TG compared to CG and may be an option for treatment of constipation.

Written from the paper’s full text.
TL;DR
In adults with chronic constipation, 14 days of yogurt containing polydextrose, *Lactobacillus acidophilus* NCFM, and *Bifidobacterium lactis* HN019 significantly shortened colonic transit time compared with control yogurt. Both groups improved on the Agachan constipation score, but bowel movement frequency did not change.
Key findings
- Of 47 participants, 43 (91.5%) were women; the Control Group had 21 participants and the Treatment Group had 26.
- Agachan score decreased significantly in both groups: CG from 14.3 ± 2.4 to 8.3 ± 3.5; TG from 13.8 ± 2.1 to 5.3 ± 2.9, with final TG lower than final CG (p = 0.005).
- Colonic transit time at the end of intervention was shorter in the TG than in the CG (24.6 ± 12.8 h vs 33.9 ± 12.4 h; p = 0.01).
- Bowel movements per day remained unchanged: CG 0.7 ± 0.3 to 0.7 ± 0.3; TG 0.7 ± 0.3 to 0.8 ± 0.3 (p > 0.05).
Methods
- Randomized, double-blind, controlled study in volunteers aged 18–45 with chronic constipation and Agachan score 10–20; exclusions included hypothyroidism, antidepressant use, and normal CTT (≤24 h) or CTT >96 h.
- Participants consumed 180 ml unflavored yogurt every morning for 14 days: CG received yogurt only; TG received yogurt with polydextrose, *L. acidophilus* NCFM (ATCC 700396), and *B. lactis* HN019 (AGAL NM97/09513), with at least 10^9 CFU per strain per portion.
- Outcomes were Agachan score, colonic transit time by abdominal X-ray after radio-opaque markers, and daily bowel movement records; analyses used Fisher’s exact test, Mann-Whitney U test, and t-test with significance at 5%.
Limitations
- The paper does not state a limitations section.
- Evident from the text: small sample (47 participants), predominantly women (43/47; 91.5%), short 14-day intervention, and no long-term follow-up.
- Also evident: bowel movement frequency did not change, both groups improved on Agachan score, and several authors are DuPont Nutrition and Health employees, the source of the tested strains.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-09, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-09 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
