What researchers measure

Primary outcomes

  1. Safety

    Participants will be asked to note any adverse events that might occur during 45 days study treatment period in the participant diary 1 and 14 days follow-up period in the participant diary 2 and to call the investigator if any clinically significant events occur. The investigator will review the returned participant diaries together with the participant. Based on the adverse events marked in the diaries and written in medical records the number of adverse event occurrences, their nature and causality will be evaluated in all study regimes.

    Time frame: 45 days

Secondary outcomes

  1. Immunomodulation

    Evaluate difference in salivary IgA in experimental groups compared to placebo

    Time frame: 45 days

  2. Regularity

    Evaluate difference in stool consistency according to Bristol stool chart, and regularity of defecation from baseline to day 45 in experimental groups compared to control group and from baseline to end of 14 days follow up period (59 days) in the experimental groups compared to control group. Participants will be asked to track the type of their stool using the bristol stool chart, and times of defecation during the 45 day treatment period and 14 days follow up period in their diaries. On visit 2 and during the follow up phone call the investigator will review the participant diary together with the participant.

    Time frame: 45 days

  3. GI Health

    Assess number of days with gastrointestinal problems in experimental groups compared to placebo.

    Time frame: 45 days

  4. Respiratory Health

    Assess number of days with respiratory infections in experimental groups compared to placebo.

    Time frame: 45 days

Other outcomes

  1. Heart Health

    Assess the change in blood lipids from baseline to finish in experimental groups compared to plcaebo

    Time frame: 45 days

  2. Inflammation

    Assess the change in cytokines in experimental groups compared to placebo.

    Time frame: 45 days
