We explored the potential benefits of green tea catechin polyphenols (GTPs) in reducing the negative impacts of intermittent hypoxia (IH), which often occurs in sleep-disordered breathing. Over a period longer than 14 days, male Sprague-Dawley rats were provided with GTP in their drinking water as we assessed its effects on cognitive function, inflammation, and oxidative stress.
Our findings showed that GTP helped prevent some of the cognitive deficits associated with IH exposure. Notably, during cognitive tests using the Morris water maze, GTP-treated rats did not show the same decline in learning ability as their untreated counterparts, who experienced significant challenges.
Furthermore, GTP intervention also impacted biological markers. We observed that the untreated rats exhibited increased oxidative stress, evidenced by higher levels of malondialdehyde, while GTP-treated rats showed a remarkable reduction in these harmful compounds. The study also indicated a notable decrease in markers of inflammation and damage in the brains of GTP-treated rats, offering insights into how green tea might counteract the detrimental effects of sleep apnea.
Overall, this research highlights the potential of GTP as a complementary approach in managing the cognitive and biological challenges associated with sleep-disordered breathing. This opens up exciting avenues for future investigations into the therapeutic roles of dietary interventions in sleep health.

L-theanine improves sleep quality safely
We examined whether L-theanine, a natural amino acid found in tea, could improve sleep quality, especially for individuals affected by sleep apnea. Through various sleep assessments and questionnaires, we found that taking 200 mg of L-theanine before bedtime offers benefits not by putting one to sleep, but by easing anxiety.
This means users can experience better sleep without the sedative side effects commonly associated with traditional sleep aids. Importantly, L-theanine should not cause daytime drowsiness, making it a versatile option any time of the day.

After struggling with sleeping pills, I found this supplement to be the perfect alternative. I initially required substantial sleep but sought to manage my reliance on medication. This product has greatly reduced my stress and aided my ability to fall asleep naturally. It calms my overactive nerves, allowing me to relax without feeling drowsy during the day. It’s an ideal supplement for me, and I will continue to use it.

Wonderful! Theanine improves memory and enhances attention. It also aids sleep and relieves stress in both adults and children. I've noticed a significant difference in my child’s behaviour on days he takes it versus when he doesn’t. An excellent product!

It's a miraculous remedy. Thanks to it, my sleep has normalised and my nervous system has stabilised. The outcome compared to magnetic therapy plus vitamin B6 is incomparable. L-theanine is non-addictive in my case and shows visible results within a few days.

Improved sleep quality
1 people found this helpful
Better sleep and concentration under high stress! This is a great option for those needing to cope with high stress and improve mental endurance. Initially, I didn't feel the effect of Theanine immediately; it manifested gradually. I track my sleep quality daily with a bracelet. After a month, my deep sleep phase started to normalise, which had previously been lacking. I feel more cheerful, calmer, and focused, with fewer distractions. On particularly stressful days, I take two capsules. The effect has been significant; I highly recommend it.

Relieves insomnia
1 people found this helpful
Taking one tablet at night allows me to sleep well and wake up refreshed. L-theanine, an amino acid in teas and some mushrooms, has no side effects like melatonin. When I take magnesium with L-theanine, especially after a stressful day with excessive coffee, it alleviates my insomnia noticeably. I feel relaxed, waking as if from a deep sleep. The quality is good, and the taste is neutral, hence, I purchased a second bottle.

Effective calming aid

These caplets work great. I pair them with 5mg of melatonin and a couple of magnesium pills to help me sleep at night and have better energy the next day. They help me feel calm enough to sleep and quiet my anxious thoughts. The caplets are a good size and easy to swallow. This is a high-quality, effective product at a low price.
