    Introduction Metabolism is the sum of all anabolic and catabolic reactions within a living organism to sustain life. The energy required to perform these reactions is provided by oxygen in the form of ATP, therefore the oxygen consumption rate can be measured to determine the metabolic rate. Since oxygen is obtained through respiration, the efficiency of an organism’s respiratory system affects its metabolism.

    How strong the effects of the stimulant are is an area of debate, but some studies show that any amount above 400 milligrams of caffeine per day is unsafe for adults, and particularly dangerous for children (Mayo Clinic). Drinking amounts above this causes a variety of neurological side effects, such as irritability, insomnia, nausea, and anxiety (Drugs.com). Studies have also found that L-Theanine, a major chemical found in caffeinated tea, makes these effects stronger and more pronounced, as it allows your body to absorb the caffeine more efficiently (J, Bryan). But you do not need to consume a large amount of caffeine to experience these side effects, even in the average person just a small dosage can cause pronounced symptoms, though they are less severe in strength (Mayo Clinic).
