92 mg in a 16 oz can
Mtn Dew Kickstart is a juice-flavored, carbonated energy drink from PepsiCo. A full 16 oz can contains 92 mg of caffeine. The nutrition label lists two 8 oz servings of 46 mg each, but the can is sold as a single container, so the practical dose is the full 92 mg unless you split it.
At 92 mg, Kickstart is a moderate dose. It is slightly more than the caffeine in a typical 8 oz cup of black tea and about half the caffeine of a 12 oz Red Bull. For many adults, it is below the 200 mg single-dose figure EFSA notes can affect sleep in some people.
Serving-size confusion
Because the label uses two 8 oz servings, the caffeine line can make the drink look weaker than it is. The can is 16 oz and is typically consumed in one sitting, so 92 mg is the number to track. If you drink two cans, the caffeine is 184 mg, close to the EFSA single-dose threshold for sleep-sensitive adults.
The figure above is for the Orange Citrus flavor. Other Kickstart flavors may vary slightly, so check the specific can if the exact number matters.
Where it fits in a daily total
A 92 mg can is a modest contribution to a 400 mg daily ceiling. It is comparable to a 12 oz Mountain Dew and lower than most energy drinks in the same price bracket. Because it is lightly carbonated and juice-flavored, it is easy to drink quickly, so pacing it can help you notice the caffeine rather than stacking another drink on top before the first one peaks.
