A Study Investigating the Effect of Floradapt Mature Immune Defense on Nutrient Uptake and Digestive Health in a Healthy Elderly Population

A Randomized, Double-blind, Placebo-controlled, Parallel Study to Investigate the Effect of Floradapt Mature Immune Defense on Nutrient Uptake and Digestive Health in a Healthy Elderly Population

This trial will be investigating the effect for Floradapt Mature Immune Defense on nutrient uptake and digestive health in a healthy elderly population. Approximately 120 healthy older adults will be enrolled into the study and will consume either the probiotic or placebo supplement for 84 days and complete questionnaires as well as provide blood samples for nutrient uptake analysis (for 50 participants), immunological markers, and general markers of health. Saliva samples will be provided for analysis of sIgA and cortisol.

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
The changes from baseline to day 42 between Floradapt Mature Immune Defense and placebo in digestive health as assessed by Gastrointestinal Symptoms Rating Scale (GSRS)	Five symptom clusters depicted as Reflux, Abdominal pain, Indigestion, Diarrhoea and Constipation will be assessed from the combination of the 15 items in the questionnaire (Abdominal pains, Heartburn, Acid regurgitation, Sucking sensations in the epigastrium, Nausea and vomiting, Borborygmus, Abdominal distension, Eructation, Increased flatus, Decreased passage of stools, Increased passage of stools, Loose stools, Hard Stools, Urgent need for defecation, Feeling of incomplete evacuation). All the domains will be scored on a 4-point scale where 0 represented no symptoms and 3 represented severe symptoms. A lower score represents less symptoms.	42 days
The changes from baseline to day 84 between Floradapt Mature Immune Defense and placebo in digestive health as assessed by Gastrointestinal Symptoms Rating Scale (GSRS)	Five symptom clusters depicted as Reflux, Abdominal pain, Indigestion, Diarrhoea and Constipation will be assessed from the combination of the 15 items in the questionnaire (Abdominal pains, Heartburn, Acid regurgitation, Sucking sensations in the epigastrium, Nausea and vomiting, Borborygmus, Abdominal distension, Eructation, Increased flatus, Decreased passage of stools, Increased passage of stools, Loose stools, Hard Stools, Urgent need for defecation, Feeling of incomplete evacuation). All the domains will be scored on a 4-point scale where 0 represented no symptoms and 3 represented severe symptoms. A lower score represents less symptoms.	84 days
The changes from baseline to day 42 between Floradapt Mature Immune Defense and placebo in bowel movements and stool consistency as assessed by daily bowel habits diary	The Bowel Habit Diary consisted of a 7 items questionnaire for evaluating each bowel movement. Bristol Stool Scale is a seven-stool description and image scale within the Daily Bowel Habit Diary to assess stool shape and consistency (type 1 is separate hard lumps, where type 7 is watery stools with no solid pieces). Stool consistency is a bowel function indicator due to its correlation with colonic transit time.	42 days
