We found that administering zinc at doses of 40 and 80 mg/kg led to a significant increase in non-rapid eye movement (NREM) sleep. This means that the mice were not only sleeping longer but also showed less activity, which is a good indicator of effective sleep. Interestingly, we did not observe any changes in rapid eye movement (REM) sleep, a crucial sleep phase for dreaming and deep rest.
Importantly, we didn’t see any negative side effects, such as rebound insomnia, within 24 hours after treating the mice. This suggests that zinc could be a safe option for those struggling with sleep issues, unlike other mineral extracts we tested, such as manganese, iron, and copper, which did not affect locomotor activity at all.
Overall, our findings provide the first evidence that zinc has a direct role in promoting sleep, opening up exciting possibilities for new sleep supplements featuring this essential mineral.
Throughout the study, we focused on measuring sleep quality using several tools, including the Pittsburgh Sleep Quality Index and the Epworth Sleepiness Scale. After two months, we found that the group taking melatonin, magnesium, and zinc showed improvements in sleep quality and overall quality of life compared to the placebo group.
While the results are promising for the combination of these supplements, it's important to note that this study makes it challenging to determine the specific role that zinc alone may play in addressing insomnia. Nonetheless, the findings suggest that this combination could be beneficial for sleep in long-term care residents experiencing primary insomnia.
Notably, we observed a significant reduction in the Kupperman Index, an indicator of menopausal discomfort, particularly related to insomnia and anxiety linked with hot flushes. While the product was well-tolerated and didn't lead to any side effects, we are unable to specify the isolated effects of zinc because the benefits were observed in conjunction with other ingredients.
Overall, the findings suggest that natural supplements like ElleN® can be beneficial for managing menopausal symptoms without resorting to hormone replacement therapy, but we must be cautious in attributing the outcomes to zinc alone, given the combination with other components.

Frequently Asked Questions
Insomnia is a common sleep disorder characterized by the inability to fall asleep, stay asleep, or wake up too early and not be able to go back to sleep. Individuals experiencing insomnia may find that it affects their daytime functioning, leading to issues such as fatigue, mood disturbances, and difficulty concentrating. Insomnia can be classified into two main types: acute insomnia, which lasts for a short period often triggered by stress or life changes, and chronic insomnia, which occurs at least three times a week for three months or longer, and may require more in-depth evaluation and treatment.
Numerous factors can contribute to insomnia, including stress, anxiety, poor sleep habits, medical conditions, and the use of certain medications. Treatment for insomnia typically involves a combination of lifestyle changes, cognitive behavioral therapy for insomnia (CBT-I), and sometimes medication. Establishing a consistent sleep routine, creating a comfortable sleep environment, and practicing relaxation techniques can help improve sleep quality. If insomnia persists, it is advisable to consult a healthcare professional for proper diagnosis and customized treatment options.
Zinc is a versatile metal known for its various applications in industry and health. It is a bluish-white metallic element represented by the symbol Zn and atomic number 30 on the periodic table. Zinc is primarily used for galvanizing steel to prevent rusting, in the manufacturing of alloys, and as a component in batteries. Additionally, zinc plays a crucial role in biological processes, making it an essential trace element in the human diet. It is involved in immune function, protein synthesis, wound healing, and DNA synthesis, highlighting its importance in maintaining overall health and well-being.
While research on the effects of zinc on insomnia is still emerging, some studies suggest that it might play a role in improving sleep quality. Zinc is essential for the proper functioning of various neurotransmitters, including those that regulate sleep. A deficiency in zinc may lead to disruptions in sleep patterns, and supplementation could potentially help those who are lacking in it. However, the evidence is not yet conclusive, and more research is needed to thoroughly understand the relationship between zinc supplementation and insomnia.
It's worth noting that zinc alone is unlikely to be a comprehensive solution for sleep issues. Factors such as overall diet, lifestyle, and existing medical conditions play significant roles in sleep quality. If you're considering using zinc to aid insomnia, it's best to consult with a healthcare professional for personalized advice and to explore a holistic approach to better sleep.
Based on user reviews, it appears that people taking this supplement for insomnia generally start noticing improvements in their sleep quality within a few days to a few weeks of consistent use. Multiple users highlighted the efficacy of GABA, a key ingredient that reportedly enhances sleep quality by promoting deeper and more effective rest, particularly during the night when growth hormone levels peak (Read Review).
While specific timelines can vary, many feedback comments reflect a quick stabilization effect on insomnia and stress, suggesting that some individuals might experience positive effects relatively swiftly (Read Review). The optimal dosage mentioned in these reviews typically supports tolerance and effectiveness, making it a potentially reliable option for those struggling with sleep issues (Read Review).
Recent studies suggest that zinc may support sleep and could potentially alleviate insomnia. One study investigating the effects of zinc, among other supplements, on insomnia in elderly residents showed that those receiving a combination of melatonin, magnesium, and zinc experienced improved sleep quality compared to a placebo group [3]. Although this study indicates a positive effect, the specific contribution of zinc remains unclear due to the combination of ingredients used.
Additionally, preclinical research has provided insights into zinc's role in sleep promotion. In an experiment with mice, zinc was shown to significantly increase non-rapid eye movement (NREM) sleep, indicating its potential effectiveness as a sleep aid [2]. However, similar to the study with elderly participants, it’s difficult to isolate the effects of zinc when it's studied alongside other nutrients. Overall, while there's preliminary evidence supporting zinc's potential benefits for sleep, further research is essential to clarify its isolated effects and confirm its efficacy in treating insomnia in broader populations.
