About
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.
Full 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.

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.
Subject with a positive result for or history of positive test result(s) for human immunodeficiency virus (HIV) antibody, Hepatitis B surface antigen or Hepatitis C antibody.
Subject has a history of cancer (except localized skin cancer without metastases) within five years prior to screening.
Subject has any current orthopedic problem(s) or clinically significant history of musculoskeletal injury(ies) of the legs that the PI feels may interfere with the study exercise.

Subject has a known or suspected allergy or hypersensitivity to trial product(s), including lactose intolerance and or dairy allergies or related product(s).
Subject exhibits evidence of hepatic or renal dysfunction as evidenced by ALT or AST being ≥ 2 times the upper limit of normal or serum creatinine value ≥ 2.0 mg/dl or other clinically significant abnormal clinical laboratory value per PI discretion.
Abnormal electrocardiogram (ECG) results thought to be potentially clinically significant according to the Investigator, or QT prolongation, as evidenced by QTcF >450 msec.
Subject has a recent history (within 12 months of Screening) of substance or alcohol abuse.
Subject has taken an investigational product within 30 days of study enrollment (Visit 1).
