OLFE: oligomerized lychee fruit extract. Presented values are the mean ± SD. The p value was calculated for the difference among the groups by one-way ANOVA. The participants in the placebo group were significantly younger. They were also lower in body weight, BMI, body fat and fat-free mass compared to the other groups.
