The problem of this study was to determine the effect of supplemental liquid protein in women 40-70 years of age over a 4-week period. Weeks 1 and 3 served as the control period. During this time, no particular diet regime was required, but protein drinks were prohibited. The treatment condition occurred during Weeks 2 and 4. During this time, subjects consumed two protein drinks each day for a period of 7 days. Twenty-four hour urine collections occurred at the end of each week. Urine was analyzed for the presence of urea nitrogen. The dependent variables were urinary urea nitrogen, self-perceived wellness levels, and body weight. The results indicated that supplemental liquid protein of 30 g per day does have an effect upon urea nitrogen excretion in women 40-70 years of age. The supplemental protein did not affect self-perceived sleep, stress, food intake, exercise, or body weight levels. Energy levels were, however, higher during the supplement weeks than during the control weeks.
