Brief Summary:
The purpose of this pilot study is to determine the effects of a Single and Double Dose of Fermented Dairy Beverage on immune health and inflammatory status in healthy adults undergoing stressful exercise.

Condition or disease Intervention/treatment Phase
Healthy Subjects Other: Placebo comparator Other: Single Active dose Other: Double Active dose Not Applicable

Detailed Description:

This is a "pilot" study. A total of 45 male subjects will be randomized to receive either Active product (in 2 doses) or placebo. This is a single-blind design (subjects are unaware of product type they are receiving). Randomization is in a 1:1:1 ratio for active test product (in different doses) versus placebo. Products will consume the beverages for a 10-day period. The subjects will be subjected to a defined strenuous exercise protocol on Days 1 and 10 of the study. Blood will be collected on the exercise days (pre- and post-exercise) on Days 1 and 10.

Blood will be analyzed for markers of Immunity and Inflammation, to assess the immuno-supportive and anti-inflammatory properties of the Active product. Product acceptance and tolerability will also be assessed using a VAS scale.

Outcome analysis will be based upon changes over time (from time-point 0) for within group changes as well as between group differences. That is, study will examine differences in end-points from baseline to end-of-study; as well as differences among the three groups.

Arm Intervention/treatment
Active Comparator: Single Active Dose
Subjects are assigned to receive a single Active beverage and a single placebo beverage.
Other: Single Active dose
Subjects consume 1 placebo + 1 Active beverages daily for 10 days. The dose-response controls for volume consumed.

Active Comparator: Double Active Dose
Subjects are assigned to receive 2 doses of Active beverage.
Other: Double Active dose
Subjects consume 2 Active beverages daily for 10 days. The dose-response controls for volume consumed.

Placebo Comparator: Placebo comparator
Subjects are assigned to receive 2 doses of a placebo beverage.
Other: Placebo comparator
Subjects consume 2 placebo beverages daily for 10 days. The dose-response controls for volume consumed.




Primary Outcome Measures :
  1. Changes in Inflammatory and immune biomarkers o IL-6, IL-10, IL-1 beta and TNF-alpha [ Time Frame: Days 1 and 10 of study ]

    IL-6, IL-10, IL-1 beta and TNF-alpha; IgA, IgG, IgM, absolute neutrophil count, absolute lymphocytes, absolute monocytes, and other immune cells.

    As there are multiple variables, statistical Outcome analysis for "within and between group differences" will be based upon changes over time (from time-point 0) for within group changes [in each outcome measure] as well as between group differences. P value for significance is set at P< 0.05 for significance and will include 95% Confidence Intervals where appropriate. As this is a pilot study, no corrective factors for multiple sets of analysis will be employed.



Secondary Outcome Measures :
  1. Ease of consumption (tolerability) of products [ Time Frame: Day 10 of study ]
    Product ease of consumption (tolerability) will be measured by a Visual Analog Scale. On the VAS scale of 1-10, each subject is asked: "How would you rate your tolerability, your acceptance of this product?" This will be done to compare tolerability of the two product types.

Criteria

Inclusion Criteria:

  • 1. Males, aged 18 to 50 years of age (inclusive) at the time of screening, nonsmokers for at least 10 years at the time of screening and throughout the study.

    2. BMI between 20.0 and 34.9 kg/m2 (inclusive) at the time of screening. 3. Subject is currently exercising less than 150 minutes per week. 4. Subject is in good health and appropriate for exercise as determined by physical examination, medical history, laboratory tests, cardiac monitoring and Physical Activity Readiness Questionnaire (PAR-Q) 5. Subjects must be able to understand the study, agree to the requirements and restrictions, and be willing to give voluntary consent to participate in the study.

    6. Subject states that he is able to jog, run and/or walk on a treadmill for 60 minutes.

Exclusion Criteria:

  • 1. History of any clinically significant cardiovascular (e.g., blocked coronary artery disease, hypertension, hyperlipidemia, Wolff-Parkinson-White syndrome, etc.), respiratory, endocrine (e.g., diabetes I or II, etc.), renal, hepatic, gastrointestinal, hematologic, neurologic, psychiatric, connective tissue (e.g., Marfan syndrome, etc.) disease or disorder, or any uncontrolled medical illness which in the opinion of the Investigator would jeopardize the safety of the subject, interfere with study assessments, or impact the validity of the study results.

    2. Family history of any first degree relative (mother, father, sibling, child) with myocardial infarction before age 50 or any first degree relative with sudden, unexplained cardiac death.
