Monster Energy Zero Ultra Review – Is it Keto Friendly?

If you’re looking for an alternative to that morning coffee, check out Monster Energy Zero Ultra.

This energy blend is packed with caffeine and vitamins to rev up anyone’s morning.

It contains zero calories and zero sugar which makes it less sweet and lighter-tasting compared to the original Monsters.

But is it Keto friendly? Let’s find out!

What are the Ingredients?

How Does Monster Ultra Zero Taste?

Monster Ultra Zero drinks come in 6 different flavors.

  • White – Zero Ultra
  • Orange- Ultra Sunrise
  • Purple – Ultra Violet
  • Red – Ultra Red
  • Blue – Ultra Blue
  • Black -Ultra Black

The Zero Ultra tastes a little less sweet than the original monster but with a hint of citrus flavor. It’s very crisp and refreshing, especially when it is cold.

The Ultra Sunrise Orange flavor tastes kind of like an “Orange Sunkist” while the Ultra Violet tastes like any regular grape soda.

I haven’t tried the 3 other flavors yet, but I assume they’re just as good.

In my opinion, the best time to consume these Monster Ultra Zero Drinks would be right away in the morning, or before your workout. This will give you a clear-headed type of energy which will help you get through any tough task.

Does Monster Ultra Zero Contain Any Side Effects?

Most side effects will most likely be coming from the added 140mg mg of caffeine. Please try to limit your consumption to two cans a day.

People who are sensitive to caffeine, children, and those pregnant should not consume this beverage.

If it’s your first time trying these, its best to drink half the can to see how well you react.

And if any out of the ordinary symptoms arise, it is best to avoid completely.

Are Monster Ultra Zero Drinks Keto Friendly?

To answer the main question, are these keto friendly? Yes! The sweeteners they use is Erythritol and Sucralose, which has little to no effect on blood sugar. 

But make sure to limit yourself to a couple of cans a day because of the caffeine content.
