Brief Summary

The use of probiotics is a widespread clinical practice to improve the composition of the microbiota in healthy and pathological patients. However, in recent years, postbiotics have begun to be used that can exert a certain anti-inflammatory effect at the intestinal level. Among them, Bifidobacterium longum (CECT 7347) has been used in various clinical trials with promising results. It has immunoregulatory properties and an excellent ability to attenuate the activity of epithelial cells at the intestinal level. However, it is necessary to carry out clinical trials to verify its effects, preferably in healthy patients who show certain gastrointestinal discomfort. For this reason, a parallel, randomized, double-blind, controlled pilot clinical trial with 2 study arms has been proposed to assess the effect of habitual consumption of a heat treated postbiotic B. longum CECT 7347 on mild-moderate functional digestive disorders in a group of healthy people.

Outcome Measures

Primary Outcomes (1)

    Day 0 - Day 60

Secondary Outcomes (35)

  • Frequency of gastrointestinal symptoms

    Day 0 - Day 60

  • Gastrointestinal quality of life

    Day 0 - Day 60

  • Defecation pattern

    Day 0-Day 60

  • Visceral sensitivity

    Day 0- Day 60

  • Zonulin concentration

    Day 0 - Day 60

  • +30 more secondary outcomes

Masking Details
The masking of the study will be achieved through the identical presentation and characteristics of the product to be consumed. The principal investigator will supply the participants with both the experimental product and the placebo, depending on the randomization. Randomization will be done blindly, so that the participants and the researcher will not know which treatment has been assigned (Experimental or Placebo). Six codes have been generated, 3 for each arm (arm 1: 2325, 2329, 2324; arm 2: 2338, 2333, 2331). The unmasking will take place at the end of the experimental period.
