CLEAR or an energy drink?
CLEAR is a caffeinated drink powder. Here is how its label compares with three canned energy drinks on serving size, caffeine, sugars, and calories.

CLEAR is sold as a zero-sugar powder; its Supplement Facts panel does not list a sugars line. “Not listed on Monster’s page” means Monster’s product page does not give that value. Monster’s product page states its caffeine content for 16 fl oz and does not state the serving for its calorie figure.
Reading the numbers
Common questions.
How much caffeine is in one scoop of CLEAR?
The Supplement Facts label lists 200mg caffeine from green tea per two-scoop serving, so one scoop contains 100mg.
Do these drinks list B vitamins?
CLEAR’s label lists seven B vitamins. Red Bull and Red Bull Sugarfree list niacin, pantothenic acid, vitamin B6, and vitamin B12. Monster’s product page does not list vitamins.
