The Lo Carb (just 9 grams) version of Monster Energy Drinks contains 140 mg of caffeine per 16 ounce can or 8.75 mg per fluid ounce.

A regular Monster Energy has 230 calories and 58 grams of carbs while the Lo Carb option has just 30 calories and 9 grams of total carbs. While these energy drinks will never really be considered "healthy", this version is closer to that title.

Is Monster Lo Carb's Caffeine Content Considered High?

At 140 mg of caffeine per can the overall caffeine content would be considered somewhat high but not all that much more than a standard 12oz cup of coffee and less than the standard Monster Energy Drink.

Where Monster Energy drinks out perform coffee in terms energy is from the stimulant stack added on top of the caffeine. This drink has 500% of your suggested daily value of B12 in just one can.

The FDA's recommended limit for adults is 400mg per day, so while this is considered to be well within the healthy limits, we do not suggest consuming more than one of these daily due to the high stimulant levels and massive amounts of added sugar.

Caffeine can have side effects like nausea and irregular heartbeat if too much is taken at once. Because of this, it's best not to consume more than two cans in a 24-hour period unless you know what you're doing—or else ask your doctor first!

Is Monster Lo Carb's Sugar Content Considered High?

According to, the average adult should consume no more than 30-40 grams of sugar per day. Since Monster Energy has just 6 grams of added sugar in a can, the sugar content compared to most energy drinks is actually considered low. However, it is still not zero and it is not suggested to consume more than one of these a day.

One can of Monster Lo Carb has 30 calories.

How Long Does Caffeine Stay in Your System?

Caffeine has a half-life of 6 hours, meaning that half of the amount you consumed will be out of your body within 6 hours. The other half will take another 4-6 hours to leave, so that means you'll need to wait 12 hours for complete clearance from your system. But this is just an average; some people may clear it more quickly than others due to individual factors such as age and genetics.
