Active individuals and elite athletes use caffeine to
improve performance. Being alert and having a quick reaction time and increased
endurance and energy are vital to any athlete for optimal performance. Caffeine
along with L-Theanine has shown positive effects on mood and cognition.
Caffeine is a well-known ergogenic compound to improve
mental focus, alertness, and energy. L-Theanine is known for its positive
effect on cognition.
By combining L-Theanine with caffeine, some of the
undesirable effects of caffeine use are lessened. L-Theanine reduces caffeine’s
stimulatory effects without modifying the other mechanisms for focus that
caffeine offers. L-Theanine interacts with caffeine by “taking the edge off”
and still allows the alertness provided by caffeine to remain.
The combination of L-Theanine with caffeine also may improve
cognitive function, may eliminate the blood vessel constriction normally
experienced with caffeine, and help keep the mind from experiencing wandering,
or distraction.
Our Formulation
Unived natural Caffeine and L-Theanine contains 200mg of
natural caffeine and 100mg of natural L-Theanine is a blend of 200mg of natural
caffeine and 100mg of natural L-Theanine extracted from green tea, per capsule.
Mode of Action:
1. Caffeine: Caffeine is an adenosine receptor antagonist,
meaning it prevents adenosine from being active. Adenosine is one of the
neurotransmitters responsible for drowsiness, and caffeine provides wakefulness
through this mechanism of blocking adenosine
Caffeine also interacts with the serotonergic system and can
cause changes in the acetylcholine and dopamine systems within the body.
Caffeine ingestion prior to exercise increases performance
during prolonged endurance exercise and short-term intense exercise lasting ~5
min [1].
2. L-Theanine: L-Theanine reaches blood-brain barrier that
works through glutamate receptors and increases levels of GABA and glycine in
the brain which causes relaxation. Increased GABA and glycine may increase
serotonin and dopamine, it has also been noted that L-Theanine may decrease or
inhibit serotonin synthesis.
Studies indicate that L-Theanine has pronounced effects on
attention performance and reaction time response [2].
