Brief Summary

The aim of the study is to evaluate the impact of a synbiotic containing fructo-oligosaccharides (FOS) and Bifidobacteria (VES002 LMG P-28149) on intestinal transit in middle-aged subjects characterized by a low number of defecations per week.

Detailed Description

Middle-aged subjects, who met ROME III criteria for constipation, received daily two sachets of either synbiotic or for 5 days, then they received daily 1 sachet for the next 25 days.

The primary endpoint of this trial is to evaluate the effect of supplementation in synbiotic containing fructo-oligosaccharides (FOS) and Bifidobacteria (VES002 LMG P-28149) on intestinal transit in middle-aged subjects characterized by a few bowel movements per week. The secondary endpoints are to evaluate both clinical criteria such as changes in stool appearance, quality of life and mood, relief and satisfaction of participants; and biological criteria such as changes in markers of gut function, low-grade chronic inflammation markers and gut microbiota composition. The safety of product use and compliance are also evaluated

Synbiotic group. The dietary supplement under study was composed of fructo-oligosaccharides - FOS: 4.95 gr / sachet and Bifidobacterium animalis lactis: VES002 (LMG P-28149): 5 billion / sachet. Sachets of powder were diluted in a in 200 ml of water at room temperature to be taken before breakfast. Doses were 2 sachets per day for the first 5 days and then 1 sachet per day for the next 25 days.

Placebo group. The placebo looked strictly identical to the synbiotic and contained only excipients (60% maltodextrin / 40% sucrose). Sachets of powder were diluted in a in 200 ml of water at room temperature to be taken before breakfast. Doses were 2 sachets per day for the first 5 days and then 1 sachet per day for the next 25 days.
