About
The purpose of this study is to examine the rate and concentration of amino acid absorption after a three-week pattern of milk protein supplementation with and without the addition of a single strain probiotic.
Full description
The study will be conducted using a randomized, double-blind, crossover study design. Thirty healthy men and women between 18 - 35 years of age will be recruited to participate in this study. Two supplementation protocols that each span three weeks will be completed and separated with a washout period of three weeks. Participants will be assigned in a randomized, double-blind, crossover fashion to ingest a single daily 25-gram dose of a powder milk protein and placebo or a single daily 25-gram dose of a powder milk protein plus a single strain probiotic. Upon arrival for each study visit, participants will have their resting heart rate, blood pressure, body mass, height, and body composition measured. On the day of experimental testing, subjects will arrive to the laboratory in a fasted state. Subjects will rest semi-supine for multiple blood sampling. Following baseline sampling, participants will ingest their respective supplement plus a standard bolus of milk protein (powder form, mixed with 12 fl oz of cold water). Thereafter, blood samples will be taken at 30, 60, 90, 120, 180, and 240 minutes post-ingestion. Study participants will be provided an additional three-week supply of the alternative treatment to begin after observing a three-week washout. After three weeks of supplementation, study participants will return to the laboratory for their remaining testing visit.
