                                According to ingredient labels, the standard Mug Root Beer is sweetened with high fructose corn syrup, not artificial sweeteners. The answer to whether Mug Root Beer contains artificial sweeteners depends entirely on the specific version you are drinking, as the Zero Sugar variety does contain them.
