Caffeine is an extremely common stimulant used around the world, and has been proven to increase energy levels, delay fatigue, and increase concentration. It is obtained from coffee beans or manufactured in a lab. Caffeine is able to benefit both anaerobic and aerobic exercises by delaying the onset of muscle fatigue and lengthening the time to exhaustion. Other benefits include supporting a healthy metabolism, which helps to burn more calories. Alertness, concentration, and short-term memory are all supplemented by the use of caffeine.
Along with caffeine, these capsules also contain L-Theanine. Theanine’s main benefit is to promote relaxation. Because caffeine can cause jitters and headaches in some users, theanine is used to offset these effects while still retaining the benefits of alertness, reaction time, and delayed fatigue. Each capsule contains a mix of 200mg of theanine and 100mg of caffeine, and are provided in an easy and pre-measured dosage that takes away the trouble of having to take two different supplements. The recommended dosage is one capsule per day.
