We explored the effects of zinc on sleep by looking at how it might help with insomnia. In our study, we gave mice a zinc-containing yeast extract and monitored their behavior and brain activity. The results were quite promising.
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.

We conducted a double-blind, placebo-controlled study in a long-term care facility in Italy to assess whether nightly supplementation of melatonin, magnesium, and zinc could help improve primary insomnia in elderly residents. A total of 43 participants, mostly in their late 70s, were divided into two groups: one received a combination of these supplements, while the other received a placebo for eight weeks.
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.

We tested the effectiveness of a unique nutraceutical product, ElleN®, aimed at alleviating postmenopausal symptoms, particularly sleeplessness due to anxiety and hot flushes. This product contains several natural ingredients, including zinc, but we acknowledge that its effects are evaluated in combination with others. In our study, women experiencing mild to moderate/severe menopausal symptoms took one tablet daily for three months.
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.

Effective for insomnia
1 people found this helpful
Zinc has a stabilising effect on insomnia, depression, autonomic disorders, and other conditions, like menopause or old age. The quality of the natural ingredients relieves stress, stimulates brain function, improves concentration, boosts performance, and normalises sleep and mood. The capsules are medium-sized. GABA, a neurotransmitter, enhances sleep quality, with peak growth hormone release at night. This component mitigates stress factors and promotes significantly deeper and more effective sleep. The dosage is optimal.

Reduces insomnia symptoms
For immunity, this product stabilises insomnia, depression, autonomic disorders, and other conditions, for instance, during menopause or old age. The natural ingredients relieve stress and stimulate brain function, enhancing concentration and performance while normalising sleep and mood. GABA, a neurotransmitter, improves sleep quality, with growth hormone levels peaking at night, facilitating deeper sleep and effectively combating stress.
