An open, parallel study on elderly persons (70-96 years) living in an institution and suffering from constipation. The aim was to study whether orange juice with probiotics could reduce constipation.
The control group (n=6) ingested ordinary juice throughout the 10-week study period. Two groups were given probiotics, but began with ordinary juice for 3 weeks, then 4 weeks with probiotic juice and 3 follow-up weeks with ordinary juice. One group (n=12) was given juice containing Lactobacillus reuteri ATCC 55730 and another group (n=8) was given juice with a bacteria blend of Propioniibacterium freudenreichii and Lactobacillus rhamnosus.
A modest positive effect on increased frequency of defecation was seen in both probiotic groups: during the active treatment period in the group ingesting the bacteria blend and during the follow-up period in the Lactobacillus reuteri group.
Conclusion: The ingestion of a probiotic-containing orange juice by elderly in an institution had a modest effect on relief of constipation.
