Monster Energy Drink and associated brands has become the number 2 top selling energy drink world-wide and can now be found in many countries.

Note: Monster Energy Drink in the UK, Australia, New Zealand, and most other countries come in a 500ml can with 160mg of caffeine.

The complete Monster Energy Drink line comes in over 25 different varieties and varies according to location. The original Monster Energy Drink comes in a 16oz can as well as Mega Monster size can, which is a 24oz resealable screw top.

Note: Consumer Reports recently tested Monster and found it to have, on average, 184mg per 16 fl.oz. can. This is slightly more than what Monster states, which we have listed above.

Many of the Monster drinks have the same caffeine content per ounce, but some are slightly higher due to the same energy blend being used in drinks with less volume.

The caffeine content is less per ounce in countries with stricter caffeine laws such as Australia and New Zealand. Popular variations of the Monster Energy Line are as follows:

  • Monster Extra Strength- Infused with nitrous oxide
  • Java Monster- Coffee flavored energy drinks
  • Monster Ultra- Zero Calorie beverages
  • Muscle Monster- Protein infused milk based energy drinks.

Of course there are many flavors in the standard Monster Energy line including juice varieties. Information on many of the different versions of Monster are found in our huge caffeine content database.

Monster Energy has a similar marketing plan to that of their biggest rival Red Bull. They sponsor huge extreme sporting events as well as individuals in each sport. Also, you will see them promoted at music festivals around the world.
