Values are means±SEM and were analyzed using a linear mixed model with group (SUPP or CON), time (prior to study entry, and weeks 6 and 19), and the group-by-time interaction as fixed factors; subject as a random factor; and baseline values as covariates. For each outcome, different superscript letters represent significant differences over time within each group. Significance accepted as P < 0.05. DXA, dual-energy x-ray absorptiometry; BMI, body mass index; SUPP, supplement group (n = 25); CON, control group (n = 24).

¹Group-by-time interaction (P < 0.05).

²Main effect for time (P < 0.05).
