How much caffeine is in a can?

Monster does not print the exact figure on the Ultra line, but Ultra drinks carry roughly the caffeine of a strong coffee per 16 fl oz can. Treat it as a full-strength energy drink, not a light one.

Does it really have zero sugar?

Yes. Ultra Fantasy Ruby Red is sweetened without sugar, so it has no sugar and no calories.

How does it compare with other Ultra flavors?

It is fruitier and sweeter than Ultra White or Ultra Paradise. If you like candy-style flavors, it fits; if you prefer a drier taste, the other Ultras are closer.

Yes, it is a carbonated drink. It tastes best well chilled.

Anyone limiting caffeine, pregnant or nursing women, and children should skip it or check with a doctor first.

Our take on the Ultra Fantasy Ruby Red 15 Pack - 16 Fl Oz

Monster Energy Ultra Fantasy Ruby Red is a zero-sugar energy drink in the Ultra line, flavored with a ruby red fruit taste. Each can is 16 fl oz and carries the caffeine and B-vitamin blend Monster's Ultra drinks are known for, without the sugar or calories of the original green can. It suits people who want an energy drink with a lighter, fruit-forward profile rather than the heavy original. Against other Ultra flavors it is sweeter and more candy-like, which divides drinkers.
