We conducted a double-blind, placebo-controlled clinical trial to investigate the effects of magnesium supplementation on insomnia in elderly individuals. Our study involved 46 participants who were assigned either to receive 500 mg of magnesium daily or a placebo for a duration of 8 weeks.
Throughout the study, we employed various questionnaires, including the Insomnia Severity Index (ISI), to evaluate the participants' sleep quality both before and after the treatment period. We also monitored the intake of other nutrients and performed blood tests to assess hormone levels related to sleep.
The results showed that magnesium supplementation led to significant improvements in areas such as sleep efficiency, sleep onset timing, and overall insomnia severity. We observed increases in serum levels of melatonin and changes in cortisol and renin levels, indicating a physiological response that could enhance sleep quality.
Overall, it seems that supplementing with magnesium has the potential to improve sleep for older adults struggling with insomnia. This finding could pave the way for new, accessible treatment options for those affected by sleep disorders.

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 explored the effects of magnesium supplementation on insomnia in older adults through a systematic review and meta-analysis. Our investigation included several studies that compared magnesium with a placebo or no treatment.
We found three randomized control trials involving 151 older adults across three countries. The pooled results indicated that individuals taking magnesium had a notable decrease in sleep onset latency, averaging a reduction of 17.36 minutes compared to those on placebo. However, the improvement in total sleep time, which increased by 16.06 minutes in the magnesium group, did not reach statistical significance.
Despite these findings, we must emphasize that the overall quality of the research is below standards necessary for making firm recommendations. All studies reviewed showed a moderate to high risk of bias, and the evidence quality ranged from low to very low. Nonetheless, magnesium is an affordable and widely accessible option for those struggling with insomnia symptoms, suggesting it may be a reasonable consideration for some older adults.

We explored the potential benefits of a supplement containing magnesium, melatonin, and vitamin B complex in treating insomnia. The study involved 60 patients diagnosed with insomnia, who were divided into a study group and a control group. Over three months, the study group received a daily dose of the supplement, while the control group did not receive it.
At the start, both groups had similar levels of insomnia, indicated by their scores on the Athens insomnia scale. However, after three months of supplementation, the study group showed a significant improvement, with their insomnia scores decreasing, indicating mild insomnia. In contrast, the control group’s scores remained stable, suggesting they continued to experience moderate insomnia.
Although magnesium was part of the supplement, the study design makes it challenging to isolate its specific effects on insomnia. Nevertheless, we observed that combining magnesium with melatonin and vitamin B complex potentially enhances sleep quality for those struggling with insomnia.

We conducted a double-blind, placebo-controlled clinical trial in a long-term care facility in Italy to explore whether nightly doses of melatonin, magnesium, and zinc could benefit residents suffering from primary insomnia. Our study involved 43 participants, who were either given a combined supplement of these nutrients or a placebo for eight weeks.
The primary objective was to measure sleep quality using the Pittsburgh Sleep Quality Index, while we also considered secondary indicators like daytime sleepiness and overall quality of life. The results revealed that the combined approach of melatonin, magnesium, and zinc appeared to improve both sleep and quality of life for residents struggling with insomnia.
However, since magnesium was tested alongside two other supplements, we cannot clearly attribute the benefits directly to magnesium alone. Overall, the findings suggest a positive effect on sleep quality and well-being for long-term care residents dealing with insomnia, but we must be cautious in isolating each nutrient's individual effectiveness.

We conducted a randomized controlled trial focusing on individuals with diabetes who struggle with insomnia. Over two months, we examined the effects of magnesium and potassium supplementation on sleep quality and hormone levels. Our study included 320 patients, and after follow-up, 290 patients completed the trial. We assessed insomnia severity using the Insomnia Severity Index and analyzed changes in melatonin and cortisol levels, which are key sleep hormones.
Our findings indicated that magnesium supplementation—whether alone or in combination with potassium—had a notable positive impact. Participants who received magnesium and potassium demonstrated significant improvements in both insomnia severity and sleep hormone levels. It was exciting to see how these supplements could enhance sleep duration and quality in those facing the dual challenges of insomnia and diabetes.
Although the combination of magnesium and potassium was effective, we recognize that this limits a clear assessment of magnesium's isolated effects. Nevertheless, our research adds valuable insights on how these minerals may play a role in managing insomnia among diabetic patients.

Magnesium may aid post-surgery insomnia
We conducted a study to explore how magnesium affects insomnia in patients undergoing lumbar fixation surgery. Our research involved 80 participants, divided into two groups: one received conventional general anesthesia supplemented with magnesium sulfate, while the other had standard anesthesia without magnesium.
We assessed various factors, including insomnia severity using the Insomnia Severity Index and post-operative delirium through the Memorial Delirium Assessment Scale. Interestingly, our findings indicated a significant relationship between the administration of magnesium and reduced instances of post-operative insomnia.
This suggests that magnesium may be beneficial in easing sleep disturbances experienced by some patients after surgery. However, we also noted variations due to other factors like pain and depression, which could influence the overall results.
While the relationship is promising, it’s essential to recognize that there may be multiple factors at play that contribute to insomnia post-surgery. Overall, our evaluation presents magnesium as a potentially helpful option for enhancing sleep quality in these patients.

We examined the potential benefits of magnesium supplements for improving sleep quality through a detailed analysis of existing clinical studies. Our systematic review focused specifically on trials investigating how magnesium affects insomnia, which have gained popularity among people seeking natural remedies for sleep problems.
A total of 15 relevant studies were reviewed. Among these, eight studies looked specifically at sleep-related outcomes, often employing the Pittsburgh Sleep Quality Index (PSQI) to measure improvements. The results were promising—five out of the eight studies indicated that magnesium supplementation led to better sleep quality.
However, it's important to note that not all studies observed benefits; two showed no significant improvements, and one provided mixed results. Many of these studies varied in the dosage, type of magnesium used, and overall participant numbers, which made it challenging to draw firm conclusions. Still, the general trend suggests that magnesium could indeed be helpful, especially for those who start with low magnesium levels.
Ultimately, while the findings lean towards positive, further large-scale, randomized trials are necessary to confirm the effectiveness of specific magnesium formulations and dosages in treating insomnia. We take these outcomes seriously, considering them a first step towards understanding how this mineral can help those struggling with sleep issues.
