g., phenolic compounds, will provide more information of other ingredients in the CAJ that may have an effect on lipid metabolism. Conclusions The findings of this study suggest that CAJ enhanced fat oxidation during exercise and may enhance endurance performance, but specific studies are needed to assess this possibility.
