Benefits and Uses of L-Theanine

Benefits and Uses of L-Theanine

L-theanine is an amino acid found most commonly in tea leaves. It has been shown to promote relaxation and ease stress and anxiety, and has some cognitive benefits, including improved memory and attention. (1) L-theanine is commonly used as a supplement to help with sleep.

What is the best dosage for L-theanine?

L-theanine is believed to work by changing the way the brain works, increasing the production of serotonin and other chemicals that have an effect on your mood. (2)


What is the best dosage for L-theanine?

The ideal dosage of L-theanine for anxiety will vary from person to person. Still, the recommended daily intake is between 200-400 mg. (3) If you're looking at using this supplement alone, it's important that before taking any steps, do research on how much would be optimum based on your body weight and goals with reducing stress or improving sleep quality, etc. Larger doses may be more effective but can also cause side effects.

L-theanine is generally considered safe and well-tolerated, but it's important to consult with your doctor before starting to take L-theanine. There can potentially be interactions with other medication or side effects if you have a pre-existing condition. Always read labels carefully and follow the instructions correctly.


How much L-theanine do you need for sleep?

Sleep is a complex process that is vital to our health and well-being, but not everyone gets the right amount of sleep (4). This can be because of a wide range of factors.

The recommended dose of L-theanine for sleep is usually between 100-400 mg, and it can be taken up to two hours before bedtime. L-theanine has a mild sedative effect (but is not a sedative itself) and can help you relax and fall asleep. It may also improve sleep quality and reduce the number of times you wake up during the night. (5)

L-theanine supplements are generally considered safe when used as directed, so if you're looking for a natural way to improve your sleep, L-theanine may be a good option. Unlike sleeping pills, L-theanine works with your body and the natural sleep process to help you get the maximum benefit from your sleep. Sleeping pills often work against the body's natural processes, resulting in certain side effects. (6)

L-theanine has been shown to increase sleep efficiency (7), so you spend more time in deep sleep and less time in light sleep. L-theanine has also been shown to increase the amount of time spent in the REM sleep stage (8). This is where most dreaming occurs.


The Benefits of Taking Melatonin and L-theanine Together

Melatonin and L-theanine are a great pair for helping you sleep. Some people find that this combination helps them fall asleep quicker, while others have noted increased restfulness during their slumber with the help of these two supplements alone. What could be better than getting some much-needed shut-eye? Melatonin and L-theanine together can help to reduce stress and anxiety.

The Benefits of Taking Melatonin and L-theanine Together

Melatonin is a hormone that's produced in response to darkness. If you keep your lights on during the night or go out into bright light after taking melatonin, this will stop its production and make it difficult to sleep. The hormone is used by the body to regulate the sleep-wake cycle. (9) Higher melatonin levels can help you fall asleep more quickly and stay asleep throughout the night.

L-theanine and melatonin side effects are rare when taken at the recommended dosage but can include mild headaches, dizziness, nausea, rashes, and irritability.


The benefits of taking an L-theanine supplement

The benefits and uses of l-theanine are varied, and here are just a few of them.

1. L-theanine is a great source of antioxidants.

L-theanine has strong anti-inflammatory and antioxidant-like properties that are capable of improving brain and gastrointestinal function. (10) Keeping your L-theanine levels in check is crucial for maintaining good health and preventing diseases.

2. L-theanine can help improve mental focus and cognitive function.

Research suggests that L-theanine can help improve cognitive function in older adults and those with Alzheimer's disease and dementia. (11) L-theanine can also help improve mental focus and cognitive function in healthy adults and those suffering from anxiety disorders.

3. L-theanine can help reduce anxiety and stress levels.

Anxiety reduction is enabled through the action of L-theanine on the production of serotonin, a neurotransmitter that is involved in mood, anxiety, aggression, and sleep. L-theanine can help to reduce stress levels (12) and improve mood and feelings of well-being (13).

It also seems to increase brain serotonin, dopamine (a neurotransmitter involved in pleasure, motivation, and focus), and GABA levels (14). GABA is an inhibitory neurotransmitter involved in anxiety and stress control.

Because of the increased production of these neurotransmitters, you are much less likely to be stressed out and more able to relax.

4. L-theanine liquid can improve sleep quality.

By reducing stress levels, most people will find it easier to get to sleep after taking l-theanine. L-theanine also supports longer sleep duration and deeper sleep, which leads to improved recovery. (15)

5. L-theanine liquid can boost the immune system.

L-theanine has been shown to help improve gut health by reducing inflammation and promoting the growth of good bacteria, both of which are beneficial to the immune system. (16) It helps reduce the risk of infections by boosting the immune system -  the good bacteria found in your gut is often the first line of defense against illness.
