Melatonin reduces pediatric anxiety, pain
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.

Melatonin reduces anxiety from glyphosate
Our research examined the effects of melatonin on anxiety and memory problems caused by exposure to glyphosate-based herbicides (GBH). We started with pregnant Wistar rats that were subjected to GBH during gestation and lactation. After weaning, the offspring were treated with melatonin to see if it could help mitigate the negative effects they experienced due to their early exposure.
We observed that exposure to GBH led to increased anxiety and depression-like behaviors in the rats. Additionally, it appeared to impair their memory function. In looking at oxidative stress markers in the brain regions associated with emotion and cognition, we found indications of increased stress—especially pronounced in the female offspring.
However, the inclusion of melatonin significantly reduced these anxiety levels and improved cognitive deficits. Interestingly, the benefits were notably greater in female rats compared to males, suggesting a potential sex-dependent response to melatonin treatment.

We examined the effectiveness of melatonin compared to midazolam for premedication in children, particularly focusing on anxiety levels during the preoperative process. In our systematic review of ten randomized controlled trials involving 774 participants, we found that both medications were used to help children feel more relaxed before surgery. However, when it came to their impact on sedation and anxiety, the results showed no significant differences between melatonin and midazolam.
We assessed various outcomes, including sedation and levels of anxiety in the preoperative room as well as during induction. Despite our thorough examination of the data, we noted that neither melatonin nor midazolam stood out as being more effective than the other. This indicates that when it comes to controlling anxiety, both options may work similarly for children undergoing surgery. Importantly, our findings suggest that variations in how the medications were administered and evaluated contributed to challenges in data synthesis, signaling a need for standardized approaches in future studies.

Promotes better sleep
2 people found this helpful
Works great! My 7-year-old has nighttime anxiety and often can't settle before bed. On nights when his mind races with worries, these supplements help him relax so that he falls asleep before the anxieties can return. Previously, he managed only 5-6 hours of sleep from constant waking, but now that's changed. I give it to him consistently for better results, and it seems to help regulate his sleep patterns.

Quick effect
Excellent! Works really quickly. My eldest suffers from anxiety at night, and my middle child struggles to sleep if he naps during the day. When they have trouble falling asleep, I give them this, and they fall asleep swiftly.

We examined the potential of melatonin microneedles as a novel method for treating anxiety and regulating circadian rhythms. This study utilized silk fibroin to create microneedles that deliver melatonin transdermally, offering sustainable drug release for up to 11 hours.
During our research, we found that these microneedles maintain a stable blood drug concentration for eight hours post-application. This sustained delivery method was particularly beneficial for insomnia model rats, where we saw notable improvements in both sleep patterns and reductions in anxiety levels.
The findings indicate that melatonin microneedles effectively address disrupted circadian rhythms and alleviate anxiety symptoms. Our results suggest a promising avenue for improving treatment methods, especially for those struggling with sleep-related issues.

Melatonin reduces anxiety post-surgery
In our study, we aimed to understand how melatonin might reduce anxiety and the risk of postoperative delirium in patients undergoing elective surgeries. We focused on 162 patients aged 40 to 80, evenly split into two groups—one receiving melatonin and the other receiving standard premedication with alprazolam and ranitidine.
We administered 3 mg of melatonin the night before the surgeries and monitored various outcomes related to anxiety and cognitive function. Remarkably, we found that the incidence of anxiety was significantly lower in those who took melatonin. Furthermore, patients reported better sleep quality, and cognitive function assessments indicated less cognitive dysfunction compared to the control group.
Our investigation highlighted the positive effects of melatonin, showing it not only lessens anxiety but also contributes to a smoother recovery post-surgery. This provides valuable insight for future practices in managing preoperative anxiety effectively.

Melatonin alleviates prenatal anxiety effects
We explored the impact of prenatal constant light exposure (CLE) and melatonin treatment on anxiety-related behaviors in male and female rat offspring. In our study, six groups of rats were examined, with some experiencing a standard light/dark cycle while others were subjected to CLE. We treated these groups with either a saline solution or melatonin.
Through various anxiety assessments like the open field test and elevated plus maze, we observed that exposure to CLE led to significant behavioral deficits. Specifically, the rats showed heightened anxiety levels, alongside increased plasma cortisol levels. Surprisingly, melatonin treatment repaired these behavioral issues in a way that was different between sexes.
Even though melatonin did not change overall levels of melatonin in the bloodstream or normalize cortisol levels, it did boost the expression of specific brain receptors associated with mood regulation. This suggests that melatonin may hold therapeutic potential for addressing anxiety issues triggered by environmental factors experienced during prenatal development.

Helps with sleep

Excellent! It’s my first time purchasing this children’s supplement, and I had some expectations and anxiety. I’m using it without any issues so far. It’s effective for my 4-year-old daughter, as she goes to bed by herself in less than an hour. Usually, she struggles to leave the TV behind. It takes about an hour and a half for my other daughter to see results, which I believe is down to compatibility. When used at bedtime, it helps immensely. I bought it as a trial and I'm pleased with the product!

Immediate calming effect
2 people found this helpful
The effect is visible immediately, yet the guidance states not to take it for over two weeks consecutively. We've been using the medication when needed for my child for about two weeks for anxiety during tougher times. After reading stories and creating a calm environment, it works effectively, but we must take breaks to allow the body to adjust its own melatonin levels. Regrettably, anxiety has returned but sleep quality is better at night.
