According to product listings and nutritional information, the Monster Ultra Fantasy Ruby Red energy drink, like other Monster energy drinks, is a caffeinated beverage. A 16 fl oz can typically contains around 150-160mg of caffeine, though some versions may differ slightly based on region. The "Ultra" line of Monster, which includes the Ruby Red flavor, is specifically known for being a zero-sugar option, but it still delivers the classic Monster energy blend.
