Neuro Drinks contains L-theanine, which is a compound that occurs naturally in green and black tea and is also available in supplement form. According to several studies, L-theanine provides various health benefits, including improved mental focus and sleep quality.
A Primer on L-theanine
The Neuro Drinks team explains that L-theanine is an amino acid naturally found in green tea, black tea, and specific types of mushrooms. It cannot be produced by the human body.
Research has shown that L-theanine has an observable effect on the levels of certain chemicals in the brain, such as dopamine and serotonin, both of which influence sleep, mood, and emotion. L-theanine also influences the level of cortisol in the body. Cortisol helps the body cope with stress.
Neuro Drinks’ team of experts points out that a shift in the balance of these chemicals is enough to change a person’s mood or stress levels.
The Benefits of Taking L-theanine
As mentioned earlier, consuming food, drink, or supplements with L-theanine may benefit your health. For example, many people drink green or black tea at work to boost their mental focus.
In a recent study, researchers observed that people who took 100 mg of L-theanine made fewer errors during an attention-centered task than those in the placebo group. Researchers also found that drinking 50 mg of caffeine or mixing the L-theanine with the caffeine also improved participants’ focus.
L-theanine has also been known to aid with sleep. Several studies have suggested that L-theanine may help people relax before bedtime. As a result, it may help them fall asleep more easily and deeply. This may result from specific effects of amino acids on brain chemicals that affect sleep.
In a 2018 study, researchers observed that, among a group of participants prescribed antidepressants for anxiety, those taking 450–900 mg of L-theanine daily for eight weeks reported greater overall sleep satisfaction.
Researchers also noted that the L-theanine in green or black tea might contribute to relaxation by slowing down a person’s resting heart rate, according to the experts at Neuro Drinks.
In 2016, researchers and scientists reviewed previous studies into the benefits of L-theanine. They concluded that this compound could improve a person’s mental and physical health and noted that L-theanine might carry certain neuroprotective effects that protect the brain and improve brain function.
Scientists have observed that on its own, L-theanine may improve a person’s attention and reaction times. When combined with caffeine, a stimulant, it may lead to additional improvements in their number skills and alertness.
If you’re on a weight-loss journey, replacing a sugar-rich soda or fruit juice with Neuro Drinks or another low-calorie beverage could help you achieve your goals.
However, one of the most significant benefits of L-theanine is its positive effect on the body’s immune system. Studies have found that L-theanine may help the body fight off illness by strengthening a person’s immune system. To add to this, the potential anti-inflammatory effects of the compound open up its possible use for treating symptoms related to sprains, arthritis, headaches, or even some long-term pain-related illnesses.
L-theanine may also help reduce stress, increase relaxation and lower the heart rate. These benefits may help lower blood pressure and the risk of developing cardiovascular ailments such as heart disease or stroke.
The Neuro Drinks team reviewed preliminary studies suggesting that L-theanine may increase the effectiveness of doxorubicin, a drug used in chemotherapy. L-theanine may make doxorubicin more effective by increasing the amount of the drug inside cancer cells.
Though there is growing evidence that L-theanine could benefit people’s mental and physical health, more studies will be needed to confirm the compound’s exact mechanism of action.
Per experts’ advice, the FDA has approved the additive as safe when people follow the instructions on the packaging. The research team with Neuro Drinks is excited to see the results as more studies look at the positive benefits of L-theanine.
