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.
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.
