Zen Cafe, Swiss Herbal, 30 capsules

Improves energy levels: Drowsiness is usually caused by adenosine. This inhibitory neurotransmitter is produced in the brain during wakefulness, but its levels decrease at night. If sleep is too short, adenosine levels can remain quite high. In such a situation, caffeine and theacrine can be a great support. They act as adenosine receptor antagonists - they can bind to those receptors without causing excitation, essentially blocking signal transmission. Adenosine is then unable to affect the neurons, so sleepiness is significantly reduced. But that's not all. Caffeine and theacrine can also improve levels of dopamine, a neurotransmitter that can be considered a source of energy and mental motivation. DLPA and L-DOPA are dopamine precursors. It is worth noting that the production of this neurotransmitter is a multi-step process. DLPA is converted to tyrosine, which is then converted to L-DOPA, which can ultimately be synthesized into dopamine. Our formula contains those two precursors that occur at different stages of dopamine production. As a result, the level of this compound can be raised quickly (thanks to L-DOPA) and remain high for a longer period of time (with DLPA). EGCG is another ingredient that plays an important role in this process. The human digestive tract contains an enzyme known as AAAD that converts L-DOPA to dopamine. However, this is undesirable, because in this situation dopamine cannot cross the blood-brain barrier, so it cannot get from the gastrointestinal tract to the brain. However, L-DOPA does not have as much trouble crossing the blood-brain barrier. EGCG inhibits the AAAD enzyme, preventing the conversion of L-DOPA to dopamine before reaching the brain. And let's remember that dopamine is indeed the primary neurotransmitter, but it can also be used as a substrate for the production of other neurotransmitters: epinephrine and norepinephrine. They produce a stimulating effect and mobilize the body, like dopamine, but mainly in the physical rather than the mental realm. Vitamin B12 is involved in the synthesis of all these compounds. In addition, it acts as a cofactor for enzymes that convert complex carbohydrates into glucose, the main source of cellular energy. Central nervous system stimulation is indeed a good way to reduce drowsiness, but when this stimulation is too intense, it can cause side effects such as nervousness, attention deficits and tremors. This effect can be counteracted by L-theanine, which stimulates the activity of GABA, the main inhibitory neurotransmitter that prevents overstimulation of the nervous system. By combining all these ingredients, we have a formula that can help you stay active after a sleepless night.

Improves intellectual stamina: To perform tasks that require a lot of concentration and mental resources, we may need the right level of motivation. In this regard, the ingredients in our formula can be helpful. DLPA and L-DOPA (supported by EGCG) are dopamine precursors, and B12 is a cofactor in the production of this neurotransmitter. Because dopamine affects energy and motivation levels, it can help you deal with procrastination and get things done on time. Or maybe tasks, we should say. In fact, dopamine is important for multitasking—the ability to smoothly shift focus between different objects. So, it can be easier to answer emails at the same time. letters and listen to the radio. It probably won't be that hard to get back on task quickly after being distracted. And since we mentioned distractions, L-theanine can reduce them (at least those caused by neuronal activity). This compound increases levels of GABA, a key neurotransmitter that helps calm stress and anxiety symptoms. Proper GABA activity is necessary to complete the task we have undertaken. In conclusion, our formula will make it easier to do what we planned for a particular day, even if there was a sleepless night before this day.

Supports learning abilities: Dopamine is important for the ability to focus. We have already mentioned that its activity can be improved by: DLPA and L-DOPA (as precursors), vitamin B12 and EGCG (indirectly) and caffeine with theacrine. However, the brain needs other neurotransmitters to function properly. One of them is acetylcholine, which improves the speed of information processing and stimulates cognitive functions. This neurotransmitter is crucial for memory processes, which are the basis of effective learning. Caffeine increases the release of acetylcholine in synapses and improves the density of its receptors on the surface of neurons. This effect is most intense in the hippocampus, a brain structure that controls most of the processes involved in long-term memory. EGCG is an acetylcholinesterase inhibitor, which means it inhibits the activity of the enzyme that breaks down acetylcholine. In fact, acetylcholine can have a more intense effect on neurons, making it easier to receive information. But there is another thing that can have a huge impact on our learning outcomes. Mood and general well-being, of course, because it's usually easier to learn new things when you're relaxed. In fact, there is even a state of neuronal activity called "relaxed awareness" that can be supported by L-theanine. This ingredient enhances alpha brain waves, cycles of bioelectrical activity in the brain with a frequency of 8-13 Hz. They induce not only a state of alertness, but also a state of relaxation, which can benefit cognitive functions that underlie learning. acetylcholine can have a more intense effect on neurons, making it easier to receive information.

Supports mental well-being: Bad mood after a night without or little sleep? You do not need! After all, your mood depends a lot on the activity of nervous processes and neurotransmitters. Thanks to DLPA, L-DOPA, EGCG, vitamin B12, caffeine and theacrine, we can improve dopamine activity, which helps to maintain high energy and motivation levels. In addition, this neurotransmitter is released in large amounts during activation of the reward system, a brain structure that regulates motivation and causes feelings of pleasure and satisfaction. Vitamin B12 is also a cofactor in the production of serotonin. Caffeine and theacrine increase the density of this neurotransmitter and the number of its receptors on the surface of the plasma membranes of neurons. It's no wonder that serotonin is called the "hormone of happiness" - balanced activity of this compound is necessary to achieve inner comfort and well-being. Improving serotonin activity will make it easier to enjoy a good mood. And if we wanted to stabilize it, we could consider L-theanine, which affects the activity of GABA, the main inhibitory neurotransmitter that shuts down unnecessary nerve impulses and thus helps maintain balanced brain activity. It plays an important role in stress resistance and relaxation. L-theanine can increase GABA levels by up to 20%! And because it can also improve alpha brain waves, the brain, like the whole body, is relaxed, but not drowsy. So, combined with the power of these ingredients, our formula will keep you going even after a tiring day or sleepless night.
