XS currently has 11 different flavors plus 3 caffeine-free versions which adds up to 14 different types. All its energy drinks are low in carbs and sugar, and loaded with B-vitamins to increase your energy. Too bad its B-vitamins are synthetic, making them less effective. Some of its energy drinks have no carbs, no sugar and no caffeine. One thing that concerned me about XS energy drinks are their high levels of synthetic vitamin B12. Most of them have 4,900 percent of the percent daily value. XS Gold has 8,000 percent. All of the XS energy drink flavors contain sucralose, an artificial sweetener known by independent researchers as a neurotoxin.
