Muscle Monster Energy Drink is the latest product from Monster Energy.

Basically, these drinks are a line of creamy energy drinks that also are infused with liquid protein. Muscle Monster launched with three flavors; Chocolate, Vanilla, and Coffee.

Update: Since this review was posted, the line up has changed.

Other protein infused energy drinks like XAPP Energy Drink  add protein and still keep the supplement light and carbonated, but Muscle Monster is more like Muscle Milk beverages.

The sports supplement industry is huge, so it will be interesting to see how Muscle Monster competes with giants like BSN and Muscle Milk. We recently bought a can at 7-Eleven to try for ourselves.

Here's What We Thought

We tried the coffee flavored Muscle Monster and despite the words "Energy Shake" on the can, shaking the beverage causes it to "squirt" and make a small mess.

It has a light coffee flavor and is pretty sweet to the taste. Although Muscle only contains 16g of sugar per can, it is further sweetened by the use of Sucralose and Ace-K.

The drink overall reminds us a lot of Java Monster, except this one has a dose of protein.

Ingredients in Monster Muscle Energy Drink

From what is printed on the can, Muscle Monster Energy contains the following per 15 fl.oz. can:

  • 25 grams of protein.
  • Milk: skim milk, reduced fat milk, and calcium caseinate.
  • Monster's standard energy blend, which puts the beverage at 156mg of caffeine. (looks like the coffee flavor adds about 2mg of caffeine per 8 fl.oz.
  • Along with the protein is some sugar and fat for a total of 200 calories per can.

Two in One

Muscle Monster is a pretty good two in one supplement for those that like both protein shakes and energy drinks. Muscle Monster pumps up the protein content of this drink with casein instead of whey, giving it a smoother texture. Also, this is why the product doesn't have to be shaken before drinking.

We bought ours at 7-11 and at $3.54 a can, Muscle Monster certainly isn't cheap, but muscle building supplements seldom are.

Monster Energy still ranks a solid second in world-wide energy drink sales, so we'll have to wait and see if this new product line gives them big enough muscles to catch and bring down the Bull.
