Artificial flavors and colors

You will be terrified to know that certain energy drinks flavors are chock full of toxic chemical coloring. Manufacturers use several different food dyes, but one of the most common is red 30 even those which are not red. It has been tied to reactions ranging from migraines and headaches to temper tantrums, dizziness, aggressive behavior, hyperactivity, uncontrollable screaming and crying, nervousness, kicking, inability to sit still or concentrate in children.
Adrenal fatigue
Some people become tired after caffeine intake. This is a symptom of adrenal fatigue when the adrenalin system of your body becomes overtaxed by constant high caffeine consumption.

Remember it is hard to choose a safe dose because it varies from person to person and according to an individual tolerance. Between 499 milligrams to 999 milligrams in a day period will probably lead to some of the more severe side effects.

L-Theanine
This amino acid is derived from green tea and most energy drinks and shots have begun putting so called green tea extract in their beverages. It can produce a different type of alertness than caffeine and there has been no scientific evidence of it causing adverse side effects.
