Monster Energy Ultra Vice Guava Review

Monster Energy Ultra Vice Guava is the kind of drink that announces itself before you even open the can. The packaging is loud, the flavor is tropical, and the whole thing leans heavily into Miami-energy branding.

Monster Ultra Vice Guava Flavor

The flavor is unmistakably guava-forward: sweet, tropical, and brighter than the heavier fruit-punch style energy drinks. It finishes relatively crisp for something this aggressively flavored, which makes it easier to drink cold than the branding might suggest.

Calories, Sugar, and Caffeine

Monster’s current U.S. product page lists the 16-ounce Ultra Vice Guava at 10 calories, 0 grams of sugar, and 150 mg of caffeine. That makes it a zero-sugar option, but it is still a caffeinated energy drink rather than a general hydration beverage.

Because caffeine tolerance varies widely, the useful number here is the label itself. People who are sensitive to caffeine, pregnant, managing a health condition, or otherwise unsure about stimulant intake should use that information rather than treating “zero sugar” as the only thing that matters.

Who Is Ultra Vice Guava For?

If you already like Monster’s Ultra line and want something more tropical than the citrus-heavy options, Vice Guava is easy to understand. The appeal is flavor plus caffeine, not any special wellness claim.

I would not frame it as something that “keeps energy soaring” or guarantees focus. In my experience, it is simply a strong-flavored caffeinated drink that tastes better than many of the syrupier options in the category.

Is Monster Ultra Vice Guava Worth It?

If you like guava and already buy zero-sugar energy drinks, yes. The product is still current in Monster’s U.S. lineup, so this is not a discontinued-flavor time capsule.
