Monster Energy is halal by its ingredients. Its taurine is made in a lab, not taken from animals, and the standard flavors contain no alcohol and no ingredients from animals. We mark it "depends" rather than a simple yes because not every Monster flavor is certified, and the huge range of flavors can vary. The classic green Monster and Zero Ultra are the most widely accepted. Some Monster drinks distributed by Coca-Cola carry a halal symbol in other countries.

The short answer
Monster is halal by its ingredients. Its taurine is made in a lab, and it has no alcohol and no ingredients from animals. We mark it "depends" because of certification and the very large number of flavors.
Does the taurine in Monster come from bulls?
No. This is the most common worry about energy drinks. Taurine was first found in animals, which is where the myth comes from. However, the taurine in Monster is made in a lab, so it does not come from animals.
Why do we mark Monster "depends"?
The standard Monster flavors, such as the classic green Monster and Zero Ultra, are widely accepted as halal by their ingredients. However, Monster sells a very large range of flavors that changes often, and most of them are not officially certified in the United States. So a simple "yes" for every flavor would go too far. Some Monster drinks distributed by Coca-Cola carry a halal symbol in certain countries.
