Monster Energy Ultra Red is a zero-sugar energy drink in the Ultra line, flavored with grapefruit and sold in a 16 fl oz can. Each can carries caffeine plus taurine and L-carnitine, with B vitamins and about 2 calories per 100 ml. It suits people who want a light, crisp energy drink without sugar, and it sits alongside Ultra White and Ultra Blue as a fruitier option in the same family. Buyers rate it highly, and the main knock is the artificial sweetener aftertaste that sugar-free energy drinks often carry.
