Percentage values of recommended daily intake for vitamins/minerals with diet alone according to the existing D-A-CH nutritional recommendations (D-A-CH 2016) in adolescent males. Data are presented separately for those who did not meet the recommendations (all columns left from the 100% line) and for those who did (all columns right from the 100% line), both for DS non-users and DS users. Significant differences in the percentages of recommended daily intakes for different vitamins/minerals between non-users and users are also presented (* p < 0.05; ** p < 0.01; *** p < 0.001; tested with Mann Whitney U-test)
