If you are new to the world of nootropics, then the best nootropic to start with is the combination of caffeine and L-Theanine in capsule form, as caffeine l-theanine stack. Nootropics are naturally occurring compounds that are used to enhance brain activity and increase mental alertness.  In fact, both of these are vital parts of most nootropic medicines and are therefore quite potent regarding the results that they provide.

Caffeine is widely known as the dominant element found in coffee and can have a great impact on a person’s mind. L-Theanine, on the other hand, is the dominant feature found in green tea and produces an alert mind. A combination of the two has a huge impact on the way the mind works and makes people extremely alert.

The best way to avail these naturally is by consuming coffee and tea. Although it might sound unsettling to consume both at once, you can consider drinking green tea 30 minutes after consuming coffee or vice versa. Either way, your body will have the chance to take advantage of the benefits of both of the compounds found in these beverages. If you are not a coffee or tea drinker, then you can always settle for supplements. Both of them are available in supplement form and can be consumed to utilize their positive effects on the mind.

Caffeine and L-Theanine supplements are both readily available over the counter and can be consumed orally to avail mind-altering effects.

Mechanism of Actions

L-Theanine, predominantly found in tea, is known to increase the level of GABA in the brain. GABA is a neurotransmitter that effectively calms a person down and at the same time enhances brain activity. This molecule is stronger in green tea and because of this is prescribed as a solution to anxiety and depression. Just a small amount of green tea can have a calming effect on the mind and make the person quite alert.

Research has proven that tea helps in keeping you awake and your mind alert. You achieve the same effect by consuming supplements. Caffeine has properties that energize the mind owing to the positive effects it has on it. A person will feel alert and active in no time at all, and also experience a physical boost. When the two combine, they leave a lasting effect on the person’s mind.

These two naturally occurring nootropics work towards enhancing the person’s mental alertness and dismiss the effects of anxiety and stress. The combination effectively eliminates the adverse effect of just caffeine and improves a person’s ability to focus on a task in a better manner.

The tiredness that most people feel at the end of the day is effectively eliminated, and the person feels quite energetic throughout the day.
