Visits 1 and 2
Informed consent was obtained, the SLUMS cognitive test was administered and scored, a history and physical performed, and a blood sample obtained. On the 2nd visit, a fasting blood sample (~ 30 mL) was drawn to determine baseline values and subjects were randomized in a double-blind method. A permuted block randomization procedure, stratified by gender, was used to assign subjects to EAAs or whey group. Subjects were provided with forms and training for recording their dietary intake over a 3-day period each week. Study staff dispensed approximately 10 days’ worth of study product and a consumption diary for subjects to complete after ingesting each dose.
