Probiotic supplementation for respiratory and gastrointestinal illness symptoms in healthy physically active individuals
Open accessAbstract
Background & aims To examine the effect of supplementation with probiotics on respiratory and gastrointestinal illness in healthy active men and women.Methods A randomised double-blind placebo-controlled trial was conducted. Four hundred and sixty five participants (241 males; age 35 ± 12 y (mean ± SD) and 224 females; age 36 ± 12 y) were assigned to one of three groups: Group 1 - Bifidobacterium animalis subsp. lactis Bl-04 (Bl-04) 2.0 × 10(9)colony forming units per day, CFU per day, Group 2 - Lactobacillus acidophilus NCFM and Bifidobacterium animalis subsp. lactis Bi-07 (NCFM & Bi-07) 5 × 10(9) CFU each per day) or Group 3 - placebo mixed in a drink.Results The risk of an upper respiratory illness episode was significantly lower in the Bl-04 group (hazard ratio 0.73; 95% confidence interval 0.55-0.95; P = 0.022) compared to placebo. There was no significant difference in illness risk between the NCFM & Bi-07 group (hazard ratio 0.81; 0.62-1.08; P = 0.15) and the placebo group. There was a 0.7 and 0.9 month delay in the median time to an illness episode in the Bl-04 and NCFM & Bi-07 groups respectively compared to placebo (placebo 2.5 months; Bl-04 3.2 months; NCFM & Bi-07 3.4 months). There were insufficient GI illness episodes for analysis. The NCFM & Bi-07 group but not the Bl-04 group undertook significantly more physical activity (8.5%; 6.7%-10%; P < 0.003) than the placebo group.Conclusion The probiotic Bl-04 appears to be a useful nutritional supplement in reducing the risk of URTI in healthy physically-active adults.Trial registration Australia New Zealand Clinical Trials Registry: Number ACTRN12611000130965.

From International Society of Sports Nutrition Position Stand: Probiotics (2019) · cites this paper as [68]
In the citing paper
“Daily B. animalis ssp. lactis Bl-04 supplementation for 150 days was associated with a 27% reduction in the risk of any URTI episode compared to placebo supplementation.”
From International Society of Sports Nutrition Position Stand: Probiotics (2019) · cites this paper as [68]
In the citing paper
“Similar to the type of probiotic used, the duration of supplementation has also been variable in the studies reviewed (Table 3). The shortest duration lasted 7 days [75, 76] and the longest lasted 150 days [68].”

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.
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.
