Updated October 30, 2023 by Scott Lindsay
L-theanine is a natural ingredient found in tea that has been studied for its potential to improve sleep and promote relaxation.
It is an amino acid that affects neurotransmitters in the brain, including gamma-aminobutyric acid (GABA), dopamine, and serotonin.
Research suggests that L-theanine can increase alpha brain waves, promote relaxation, and reduce anxiety, making it potentially beneficial for sleep.
Many products recommend a dosage for sleep of around 200 milligrams taken before bed.
So let's see if L-Theanine should be part of your Slumber Stack Protocol ...

How Does L-Theanine Affect Sleep?
L-Theanine, a natural amino acid found in tea, has been shown to have positive effects on sleep by influencing neurotransmitters and promoting relaxation in the brain.
When consumed, L-theanine crosses the blood-brain barrier and interacts with various neurotransmitters, including gamma-aminobutyric acid (GABA), dopamine, and serotonin.
One of the key ways L-theanine affects sleep is by increasing alpha brain waves, which are associated with a relaxed yet wakeful state of mind.
By boosting alpha brain wave activity, L-theanine promotes a sense of calmness and relaxation, making it easier for individuals to fall asleep and improve the quality of their sleep. This can be particularly beneficial for men who struggle with anxiety or racing thoughts at bedtime.
L-Theanine also blocks the binding of glutamate (a neurotransmitter associated with wakefulness) to brain cells.
By reducing the levels of glutamate, L-theanine helps promote a more relaxed and sleep-friendly environment in the brain, making it easier for individuals to transition to a state of sleep.
Overall, the effects of L-theanine on sleep are promising. It can help individuals achieve a more relaxed state of mind, fall asleep faster, and potentially improve the overall quality of their sleep.

Side Effects and Dosage of L-Theanine
When it comes to using L-theanine for sleep, it is important to be aware of the potential side effects and the recommended dosage.
While L-theanine is generally considered safe, it can cause gastrointestinal upset, especially when taken in high doses.
It is advisable to start with a lower dose and gradually increase it if needed, while monitoring any adverse reactions.
It's worth noting that green and black teas, which naturally contain L-theanine, also contain caffeine.
Caffeine can counteract the sleep-promoting effects of L-theanine, so it's recommended to opt for decaffeinated or low-caffeine options if using tea as a source of L-theanine. This will help ensure that you can fully reap the benefits of L-theanine for improved sleep without any interference from caffeine.
While L-theanine is generally safe for most men, it is important to exercise caution if you have any underlying liver problems. Although rare, there have been reports of liver problems associated with the use of green tea extract, which contains L-theanine.
If you have any pre-existing liver conditions or concerns, it is advisable to consult with a healthcare professional before incorporating L-theanine supplements into your routine.
Other Health Benefits of L-Theanine
In addition to its potential sleep benefits, L-Theanine has been studied for its effects on anxiety, focus, immunity, blood pressure, and sinusitis.
Research suggests that L-Theanine may help reduce symptoms of anxiety and promote relaxation without causing drowsiness.
It works by increasing levels of gamma-aminobutyric acid (GABA) and serotonin, which are neurotransmitters that contribute to feelings of calm and well-being.
Even cooler, L-Theanine has been found to enhance focus and improve cognitive functions.
It may help men maintain mental clarity and attention, making it a valuable supplement for those seeking improved productivity and performance.
Preliminary studies also suggest that L-Theanine may have immune-boosting properties, helping to support overall health and well-being.
Finally, L-Theanine has been studied for its potential to provide relief for symptoms of sinusitis.
Sinusitis is an inflammation of the nasal passageways that can cause congestion, facial pain, and pressure. L-Theanine's anti-inflammatory properties and ability to enhance immune function may help reduce inflammation and alleviate sinusitis symptoms.
