Nowadays, more and more people are looking for natural ways to improve their well-being and concentration. One such ingredient that is gaining popularity both in dietary supplements and functional beverages is L-theanine. But what makes L-theanine so special, and why is it worth choosing products containing the natural extract of this substance? Let’s take a closer look at this extraordinary amino acid and the benefits it can provide.
What is L-theanine?
L-theanine is a natural amino acid found primarily in the leaves of green tea (Camellia sinensis). It is known for its calming effect on the nervous system while also enhancing concentration and focus. Unlike many other dietary supplements that may cause feelings of fatigue or drowsiness, L-theanine helps achieve a state of relaxation without causing sleepiness.
How does L-theanine work?
L-theanine affects the brain by increasing the levels of neurotransmitters such as GABA, dopamine, and serotonin. These play a key role in regulating mood and emotions. Increasing serotonin and dopamine levels helps improve mood and reduce feelings of stress. GABA, on the other hand, acts as an inhibitory neurotransmitter that lowers excessive neuron activity. This leads to a sense of relaxation and reduced anxiety. As a result, L-theanine supplements can help reduce stress and anxiety, improve mood, and support cognitive functions such as memory and concentration.
Mitigating the Effects of Caffeine
Many people are familiar with the feeling of anxiety after consuming too much coffee. This often manifests as excessive stimulation, concentration problems, or even sweating. Here, a drink with L-theanine can help. Research shows that L-theanine can help alleviate these effects, making it a natural choice for those who consume large amounts of caffeine. It is L-theanine that makes matcha, despite containing more caffeine than coffee, not cause feelings of jitters and anxiety—acting as a protective agent against caffeine.
Why is it worth choosing natural L-theanine extract?
When looking for products with L-theanine, it’s important to choose those that contain natural green tea extract. Why? Natural L-theanine extract is more bioavailable, meaning the body absorbs it better and can derive greater benefits from its effects. Additionally, natural extracts often contain extra antioxidants, such as catechins, which support heart health and overall well-being. It is also worth noting that only L-theanine from natural sources (green tea leaves) can be legally sold to consumers in the European Union. Synthetic L-theanine is not permitted for sale.
