L - theanine in tea and its great health effects you may not know
Tea offers numerous health benefits, a fact well-known to many. But what makes tea such a healthy beverage? In addition to its antioxidants, tea contains a unique amino acid called L-Theanine. Various studies have demonstrated the potential of L-Theanine in enhancing mood, promoting better sleep, and preventing illnesses. Since the human body cannot produce L-Theanine on its own, tea is the best natural source of this compound.
What is L-Theanine?
L-Theanine is an amino acid found in some types of mushrooms and notably, in the Camellia sinensis tea plant. All types of tea made from this tea plant (including black tea, green tea, oolong tea, and white tea) contain varying levels of L-Theanine. Alongside epigallocatechin gallate (EGCG), L-Theanine is a natural component of tea that has positive effects on the human body.
Health benefits of L-Theanine
Stress and anxiety eduction
L-Theanine in tea has long been proven to have anxiety-relieving properties and mood-enhancing effects. The mechanism of action involves reducing negative emotional responses in the body while promoting relaxation without causing drowsiness. Other studies also suggest that L-Theanine may act as a neuroprotective agent, activating alpha brain waves, enhancing relaxation, focus, and creativity.
Improved sleep quality
L-Theanine is considered a safe and natural sleep aid. Research indicates that consuming approximately 200mg of L-Theanine before bedtime can enhance overall sleep quality without adverse effects. Notably, L-Theanine can also be used during the day to help maintain calm and relaxation, thanks to its ability to increase the levels of neurotransmitters GABA and glycine in the brain, reducing anxiety-inducing stimulants and thereby supporting better sleep.
Blood pressure regulation
Another function of L-Theanine is regulating blood pressure. You can control blood pressure by boosting the production of nitric oxide (NO), which dilates blood vessels and enables them to function normally. High NO levels can also help reduce high blood pressure. However, NO levels are modulated when exposed to L-Theanine. Additionally, L-Theanine can relax arterial walls, reducing the risk of cardiovascular disease through blood pressure regulation.
Depression treatment
L-Theanine has been demonstrated as a natural substitute for prescription antidepressants. This amino acid works by increasing alpha brain wave activity and dopamine levels in the brain. Enhanced alpha waves create feelings of tranquility and relaxation, while increased dopamine restores chemical balance in the brain. This is why many people turn to L-Theanine for depression treatment. Furthermore, L-Theanine benefits the balance of essential neurotransmitters in the brain responsible for mood stability.
How L-Theanine and caffeine work together?
In addition to L-Theanine, tea also contains caffeine. The combination of these two substances has multiple positive effects, enhancing each other's benefits more than when they work separately.
-
Energy boost: By stimulating neurotransmitters like glutamate and dopamine, both L-Theanine and caffeine can provide an energy boost.
-
Cognitive improvement: They improve cognitive function, increasing focus and accuracy for challenging tasks.
-
Limiting caffeine jitters: L-Theanine mitigates the side effects of caffeine, ensuring stable blood pressure and heart rate.
-
Reducing headaches and anxiety: It minimizes caffeine-induced negative effects, such as headaches, fatigue, and anxiety.
These cognitive-enhancing and memory-boosting properties of L-Theanine and caffeine combined can put you in the best state for a productive and efficient day.
In summary, L-Theanine in tea provides numerous positive effects on health. Even when tea contains caffeine, it doesn't produce unwanted side effects. On the contrary, caffeine, along with L-Theanine, offers significant benefits for improving memory, alertness, focus, and various cognitive functions. Therefore, if you face issues with excessive coffee consumption, tea is a healthy alternative.
