Protein Malabsorption
Conditions
Brief summary
The purpose of this study is to examine the pattern of plasma amino acid appearance after a two-week daily regimen of milk protein concentrate supplementation with and without the addition of Bacillus coagulans GBI-30, 6086 among older women.
Detailed description
Once determined eligible and providing consent, participants will be assigned in a randomized, double-blind, crossover fashion to ingest a single daily 25-gram dose of a milk protein concentrate or a similar dose of milk protein concentrate plus bacillus coagulans GBI-30, 6086. Upon arrival for each study visit, participants will have their resting heart rate, blood pressure, body mass, height, and body composition measured. Upon ingestion of their final assigned supplementation dose, standard multiple sample phlebotomy approaches will be used to collect approximately 10mL of venous blood from a forearm vein at specific time intervals up to four hours after ingestion of their final assigned supplementation dose for that period in the study protocol.
Interventions
In a randomized, double-blind, crossover fashion, study participants will supplement on a daily basis for two weeks during one study period with a 25-gram dose of either milk protein concentrate or a 25-gram dose of milk protein concentrate with bacillus coagulans GBI-30, 6086. Each dose will be ingested at the same time of day with 8 - 12 fluid ounces of cold tap water. All participants will be required to complete a supplementation log to document when each dose of their assigned protein is consumed. Upon completion of their first assigned study protocol period, participants will observe a three-week washout period by returning to their normal dietary intake and physical activity habits before beginning supplementation for the remaining study period.
