Brief summary

Active males and females consumed a probiotic for 28-days. Before and after the intervention period, participants reported to the lab in a fasted state where they consumed 25 grams of whey protein. Following drink consumption, participants provided blood draws at 15-minute intervals. Blood samples were analyzed for amino acid concentrations.
