Conclusion. Multivitamins and minerals and fat burners are popular supplements used by boxers because of their convenience and more beneficial benefits. However, boxers are still less concerned about how to use supplements. It is evident from the results that show that many boxers feel in the categories of "enough", "low" and "very low" in the use of supplements but boxers think that the use of supplements is really needed. Further research is expected, to determine the amount and type of supplement recommended specifically for boxing athletes.
