We set out to explore how long-term consumption of green tea could influence insomnia among postmenopausal women, a group known to face higher risks of depression and sleep disturbances. In our investigation, we had the opportunity to look at 386 women living in a tea-producing village. We divided them into two groups: one that regularly consumed green tea and a control group that did not.
Our findings revealed noteworthy differences between the two groups in several aspects, including the degree of insomnia. We observed that those who consumed green tea experienced less insomnia, suggesting that this delightful beverage might help improve sleep quality. Additionally, the study indicated that green tea consumption could be linked to positive changes in inflammation and estradiol levels, which might also play a role in enhancing overall well-being.
In summary, integrating green tea into the daily routine of postmenopausal women may offer a natural way to help diminish insomnia symptoms. This is a promising step toward promoting healthier lifestyles for women in this stage of life.

Insufficient evidence for L-theanine
We examined the effectiveness of various sleep medications, including L-theanine, for children and adolescents with ADHD. Out of 337 articles, only five were relevant.
While L-theanine showed some improvement in sleep efficiency, it did not significantly reduce sleep latency or increase overall sleep time. Other medications like clonidine and melatonin showed more promising results, reducing insomnia more effectively.
Overall, the lack of robust evidence for L-theanine suggests that more research is needed to confirm these findings and guide treatment options.

In our 10-week study with 46 participants diagnosed with Generalized Anxiety Disorder (GAD), we aimed to see if L-theanine could enhance sleep and reduce anxiety when combined with standard antidepressants.
While L-theanine didn’t significantly lower anxiety or insomnia severity compared to a placebo, participants on L-theanine did report feeling more satisfied with their sleep quality. Particularly, those experiencing non-clinical insomnia symptoms noted better outcomes.
These findings suggest that while L-theanine may not be a strong treatment for anxiety, it could have potential for improving sleep satisfaction.

The best natural product for insomnia I have ever used. I wake up slightly sleepy, but this passes after a shower. The calming effect lasts throughout the day, making my mind less cluttered and more focused. Definitely a keeper.

I had a paradoxical reaction which seems to be more common than I thought. Although this product works wonders for many, it worsened my insomnia and caused dizziness and a sense of sadness that I wouldn’t quite classify as depression. While it did improve my focus, I lacked the mental clarity I desired. I managed to finish two tedious tasks in three days, but that minor benefit didn’t outweigh the negatives for me. I’ll keep searching for something better.

After suffering from insomnia for five years, I was tense and exhausted despite trying countless remedies. This product has had a remarkable impact; I now sleep better and feel more energetic. Initially, I was cautious about dependency, but the effects after the first month were tremendous. Regaining a good night's sleep has revived my health and social life.

Restored deep sleep

If you have sleep troubles, I highly recommend this supplement. It saved me from severe insomnia caused by stress. Theanine has restored my deep sleep. My sister, who has chronic insomnia and relied on sleeping pills, has also seen great improvement. I take it in the morning with coffee, and it balances caffeine's effects while enhancing focus.

Improved sleep quality
2 people found this helpful
Excellent! I often experience anxiety and insomnia. After trying various medications, I found L-Theanine two weeks ago and immediately felt an enhancement. My sleep has returned to normal! I've even forgotten about a lovely dream, as I'm now sleeping soundly. The morning grogginess has disappeared too. Thank you to the developers. I will surely purchase it again.

Effective treatment

After a troubling family incident, I found myself wide awake in the middle of the night, unable to sleep. However, just 20 minutes after taking one capsule, I felt calmer and managed to drift off to sleep.

Calming sleep experience

Awesome dreams! I take this about an hour and a half before bed. I struggle with initial insomnia, but when I finally sleep, it’s wonderful. The dreams are great, unlike the creepy ones from melatonin. It’s quite a calming product; I will buy again. The shipping was super fast and perfect as always.

Not effective for me
1 people found this helpful
I purchased this to improve concentration and sleep, but it didn't help. After taking two pills, I ended up with a headache and still had insomnia. This may suit those with milder symptoms, but I've been battling severe insomnia for a long time, so calming remedies haven’t worked for me.

Reduces insomnia issues
1 people found this helpful
Taking one tablet at night helps me sleep well and wake up refreshed. L-Theanine, an amino acid from teas and mushrooms, lacks the side effects of melatonin. After consuming it alongside magnesium, my insomnia diminishes, and I feel tension relieved. Waking from deep sleep the next morning is invigorating. I'm pleased with the product's quality and have purchased a second bottle.

Recommended with caution
Definitely recommended for treating insomnia, especially when combined with 5-HTP for a synergistic effect. I enjoy great sleep and vivid dreams when using these alongside 'Only Trace minerals'.

Sleep aid for friends
9 people found this helpful
Upon taking it, the effects begin approximately 40-50 minutes later. I feel uncontrollably drowsy, as if something heavy is weighing me down, which I dislike. All my concerns fade away as I seek out the bed. However, it's a suitable sleep aid for my friend who suffers from insomnia and loves it for that purpose. Melatonin isn't for them, but this product helps to achieve timely sleep.

Calming but not for sleep
8 people found this helpful
This product works wonderfully for relaxation. It has a short half-life, so I take 100mg every four hours. I still struggle with insomnia at night, but it effectively calms mild anxiety during the day. For severe panic attacks, however, stronger medications may be needed.
