We investigated the role of melatonin in enhancing synaptic development in mouse models of autism. Through long-term oral administration over 28 days, melatonin improved social interactions and dendritic spine density in genetically modified mice.

Importantly, we found that melatonin's benefits are linked to the activation of a specific signaling pathway in the brain. However, when this pathway was blocked, the positive effects of melatonin on synaptic function were diminished. Overall, our findings highlight melatonin's promise for addressing certain autism-related challenges.

Excellent analogue of the pharmacy Melaxen. I gave melatonin to my son who struggles to fall asleep, especially when he's overexcited in the evenings. He is 6 years old and has autism. Children like him often have low melatonin levels, leading to sleep issues. Doctors often prescribe antidepressants that can harm not just the body but the brain. I sought a less harmful alternative and was recommended this melatonin. It calms my child effectively, allowing him to go to bed quietly without pills. I give him a quarter of a tablet, and he wakes up cheerful without headaches, which often accompany other medications. The price is very reasonable—240 tablets here were much cheaper than 24 in Russia. I highly recommend it!

Excellent analogue of pharmacy Melaxen! I gave melatonin to my son who struggles with sleep due to overexcitement in the evenings. He is 6 years old and has autism, often experiencing low melatonin levels. I sought a less harmful medication since many doctors prescribe antidepressants that adversely affect the brain. This melatonin has helped my child calm down and sleep well without pills; I administer a quarter dose. He wakes up cheerful and free from headaches common with other medications. I'm also pleased with the cost—24 tablets in Russia cost nearly 700 rubles, while here I get 240 tablets for a similar price. Highly recommend!

My neurologist suggested 3 mg a night to alleviate my chronic cough as a symptom of trigeminal autonomic cephalalgia. I find it works much better than the pharmacological treatments I tried, which not only failed to help but also caused debilitating side effects.

We explored how bright light therapy (BLT) can influence ADHD symptoms, especially in individuals with sleep-wake rhythm delays. The study involved participants undergoing standard treatments along with two weeks of morning BLT, which successfully advanced melatonin release and sleep timing.

As a result, we observed a significant reduction in ADHD symptoms, particularly in hyperactivity and impulsivity. Although the therapy did not change sleep quality significantly, it highlighted potential as a complementary approach to traditional ADHD treatments.

This study marks an encouraging step in finding effective alternatives for managing ADHD symptoms.

We focused on the effects of oral melatonin on anxiety and pain in children during the stressful process of venipuncture. In a double-blind, randomized controlled trial, we found that administering 0.5 mg/kg of melatonin 30 minutes before the procedure significantly reduced both pain and anxiety levels compared to a placebo.

The results showed that only 18.8% of the kids receiving melatonin reported pain, while 78.2% in the placebo group did. Furthermore, anxiety affected 44.6% of the melatonin group compared to 94.1% of those in the control group.

While melatonin appeared to improve experiences during venipuncture, its impact on the success rate was not statistically significant.

This drug was my salvation. I always suffered from anxiety, which would keep me awake for 2-3 hours. I often woke up in the middle of the night with a racing heartbeat. Taking one pill before bed works wonders; after about 20-25 minutes, I fall asleep peacefully. The sleep is very deep and enjoyable, with calm and colourful dreams. For the first time, I sleep 7-8 hours without disturbance and wake up feeling rested and ready to start my day. My overall condition has improved without any lethargy or weakness.

We evaluated the effects of melatonin treatment on emotion, sleep, and quality of life in 100 healthy perimenopausal women. Participants were divided into two groups: one receiving melatonin and the other a placebo over three cycles.

After analyzing various hormonal levels and using questionnaires to assess perimenopausal symptoms, sleep quality, anxiety, and mood, we found that melatonin significantly alleviated climacteric symptoms.

Participants reported improved sleep, enhanced mood, and a better overall quality of life without serious side effects.

After ten years of insomnia resulting from menopause, I found melatonin to be the most effective solution compared to GABA and tryptophan. For the first time in ages, I experienced actual sleepiness and could return to sleep if I woke during the night. Initially taking vitamin D prior to melatonin may have helped.

The product truly works. I bought it knowing its benefits, not really focusing on any downsides, as I haven’t encountered any. With this product, I enjoy a deep sleep and notice my rash is improved by morning. I wake up early, around 5 am, and aim to stay awake until 10 pm. I engage in morning workouts from 7 am before heading to work. Melatonin enables me to get sufficient rest and wake up refreshed. Just ensure that after taking a pill before bed, you switch off all lights and the TV. The hormone functions best in complete darkness. I highly recommend trying it; you won’t regret it.

We explored the impact of melatonin on patients with multiple sclerosis (MS), aiming to improve heart function and sleep. In a randomized controlled trial, participants received either melatonin or a placebo for 12 weeks.

We observed significant improvements in heart rate variability and markers of oxidative stress, suggesting that melatonin could enhance heart health and lower stress in MS patients. Additionally, sleep quality and quantity also improved with melatonin use.

This study indicates that melatonin might be a beneficial treatment option for managing cardiac issues and sleep disturbances in MS.

Really helps to establish a sleep routine and is non-addictive! I had a terrible schedule for years, only sleeping in the morning and working late at night. My body was exhausted, leading to hair loss and nodular alopecia, worsened by breastfeeding. After taking melatonin, I fell asleep quickly and adjusted my routine. My bald patches healed, and my hair stopped falling out. Occasionally, I stray from routine, but melatonin helps me return to normal.

We evaluated whether melatonin and bright-light phototherapy could help alleviate symptoms of chronic fatigue syndrome (CFS). In a controlled study with thirty participants, we assessed the effectiveness of these treatments by measuring various symptoms over several weeks.

Unfortunately, we found that neither melatonin nor phototherapy led to significant improvements in the patients’ symptoms or overall health. Our findings suggest that these treatments shouldn't be promoted for CFS unless proven beneficial.

We explored how melatonin could affect nausea in patients with small intestinal neuroendocrine tumors (SI-NETs). Our research involved studying tumor tissue from 26 patients, examining their primary tumors alongside metastases for the presence of melatonin and its receptors.

Interestingly, we found that higher melatonin levels in the body were linked to reported experiences of nausea. Specifically, patients with higher plasma melatonin levels at both time points indicated more frequent nausea occurrences. This underscores the potential role of melatonin in influencing nausea symptoms.

However, it's notable that in those cases where the disease was stable or improving, plasma levels of melatonin dropped after treatment, suggesting a complicated relationship between melatonin levels and treatment responses. These findings provide some valuable insights into the endocrine roles of melatonin in SI-NETs and signal a need for future studies to further dissect these relationships.

We developed a new way to deliver melatonin for those struggling with insomnia by creating microneedles made from silk fibroin. These tiny needles are designed to improve how the body absorbs melatonin, making it easier for people to get to sleep and stay asleep.

Our research shows that these microneedles can release melatonin steadily over a period of 11 hours. When we tested it on animals, we found that the microneedles maintained stable levels of drug in the bloodstream for up to 8 hours. This is promising news for individuals who may need help with their sleep cycles.

Additionally, the microneedles not only helped regulate sleep but also made a noticeable difference in anxiety levels in insomnia model rats. By improving the disrupted circadian rhythms, melatonin loaded into these microneedles could lead to significant therapeutic benefits.

We believe this innovative approach could enhance patient compliance and provide effective sleep aid for many in need. It’s an exciting development in the field of transdermal drug delivery for improving sleep quality and overcoming insomnia.

We assessed how melatonin affects dizziness in patients dealing with sleep disturbances tied to psychiatric conditions. In a study with 175 participants, we found that melatonin was slightly less effective than trazodone and doxepin in improving overall sleep quality. However, it stood out for having a low incidence of adverse effects. Specifically, the rates of dizziness associated with melatonin use were measured, showing a relatively low occurrence.

While it did not provide the most substantial improvement in sleep quality, melatonin showed promise in enhancing tolerability among users. Only 10% of participants reported dizziness, which indicates that melatonin might be a safer option for those worried about side effects from more potent medications. By choosing melatonin, patients can potentially find a balance between managing sleep disturbances while minimizing unwanted symptoms like dizziness.

Overall, we observed that for individuals focused on avoiding adverse effects, melatonin serves as a viable alternative within this treatment landscape. Its effectiveness in curbing dizziness contributes to discussions on how best to treat sleep disorders in psychiatric patients without compromising their comfort.

We explored how melatonin-based treatments, particularly agomelatine, can affect headaches, focusing on hypnic headaches (HH). This form of headache typically occurs during sleep, disrupting the rest of those affected. A fascinating case of a 58-year-old woman who experienced these nocturnal headaches for three years demonstrated the potential benefits of agomelatine.

After being prescribed 25 mg of agomelatine at bedtime, she reported an impressive 80% reduction in headache frequency and severity within a month. Remarkably, her headaches completely resolved after three months, allowing her to discontinue the medication.

This case highlights the importance of exploring prophylactic treatments aimed at reducing nighttime awakenings caused by HH. Given the significant impact these headaches can have on sleep quality in older populations, treatments that target melatonin receptors could offer a promising avenue for relieving this condition.

We investigated how melatonin affects patients with obstructive sleep apnea and insomnia. In a double-blind trial, thirty patients received either 10 mg of melatonin or a placebo for a month.

The results were striking; those taking melatonin reported better sleep quality, less daytime sleepiness, and greater adherence to their PAP devices. Improvements were noted across several assessments: the Pittsburgh Sleep Quality Index, Insomnia Severity Index, Epworth Sleepiness Scale, and Functional Outcomes of Sleep Questionnaire showed significant gains for the melatonin group.

Thus, melatonin appears to be a promising option to enhance sleep quality and treatment compliance in this challenging patient group.
