Magnesium oxide treats leg cramps
We conducted a study to evaluate how effective magnesium oxide monohydrate (MOMH) is in treating nocturnal leg cramps (NLC). This was a randomized, double-blind, placebo-controlled trial involving multiple centers in Ukraine, where participants took either MOMH or a placebo nightly for 60 days.

Our focus was on measuring the frequency and duration of cramps, the pain they caused, and how they affected sleep quality and overall life satisfaction. We used thorough statistical methods to compare the results between the two groups.

The findings indicated that MOMH is both effective and safe for individuals dealing with NLC. Participants reported improvements in their symptoms, demonstrating that this magnesium supplement can play a helpful role in managing nocturnal leg cramps.

Magnesium reduces pregnancy leg cramps
We sought to understand the effectiveness of oral magnesium in treating leg cramps experienced by pregnant women. Our study was well-structured, involving a double-blind, randomized, placebo-controlled design. It included 86 healthy pregnant women between 14 to 34 weeks of gestation who encountered leg cramps at least twice a week, and we followed them over a four-week period.

At the end of the study, we discovered that the women taking magnesium bisglycinate chelate (300 mg per day) reported a significant reduction in cramp frequency—86% experienced at least a 50% drop compared to only 60.5% of those taking the placebo. Additionally, those on magnesium also noted a notable decrease in cramp intensity, with 69.8% achieving a similar improvement versus just 48.8% in the placebo group.

Encouragingly, we found no major side effects reported in either group, such as nausea or diarrhea. Our findings suggest that magnesium supplements can effectively reduce both the frequency and severity of leg cramps during pregnancy, offering a potential treatment option for women dealing with this common issue.

Magnesium's potential against cramps
We set out to investigate whether magnesium citrate could be an effective remedy for those who experience bothersome leg cramps, particularly at night. In our study, we used a randomised, double-blind, cross-over, placebo-controlled design to ensure reliable results. Participants suffering from regular leg cramps were recruited and given either magnesium citrate or a matching placebo over six weeks.

Our findings revealed that those who began the trial with the placebo experienced an average reduction in cramps when taking magnesium, with a median of 5 cramps compared to 9 on the placebo. Moreover, a notable percentage of participants felt that the magnesium treatment had indeed helped them, with 78% reporting benefits, as opposed to 54% who felt the placebo was effective.

While these results suggest that magnesium may have a positive impact, it’s essential to mention that the impact on cramp severity and duration wasn’t significantly different between the two groups. Additionally, some participants did report experiencing diarrhoea as a side effect of magnesium. Overall, we believe magnesium shows promise in alleviating nocturnal leg cramps and recommend further research to fully evaluate its effectiveness.

Leg cramps eliminated
25 people found this helpful
Cured my leg cramps! I endured nightly leg cramps for years. I began taking calcium magnesium capsules before bed, which helped but didn’t fully eliminate the cramps. I would still awaken with terrible leg cramps at least once each night, needing magnesium spray for relief. However, since starting these tablets before bed, I’ve had NO CRAMPS at all! For the first time in five years, I’m cramp-free! I highly recommend these!

Reduced my night sweats! I've been taking this form of magnesium for six months. Initially, I started it for heart health, but I noticed several benefits. The most significant impact has been the elimination of muscle cramps in my legs during sleep, alongside regular bowel movements and, importantly for me, fewer night sweats and hot flashes. To achieve these benefits, I've been taking one tablet before bed, alongside my morning dosage. After researching various magnesium supplements, I believe magnesium oxide is the best option for me, being the most commonly bought and the least expensive.

They stopped my nightly leg cramps! Recently, my doctor recommended magnesium for my severe cramping, which often woke me throughout the night. I found it challenging to swallow pills, as they cause me to choke unless they're small or coated. These tablets are pea-sized and uncoated, making them easy to swallow. My leg cramps were less intense within the first few nights, and by the third night, they were nearly nonexistent. I trust the Nature Made brand, and these are the first magnesium supplements I've tried; I'm committed to continuing them!

Magnesium's potential in cramps
We explored the effects of magnesium treatment in a unique case involving a 62-year-old woman with stage IV colon cancer undergoing oxaliplatin therapy. Shortly after her first infusion, we observed that she experienced significant neurological symptoms, including right hemibody paresthesia, muscle cramping in her right calf, and dysphonia.

To address these symptoms, she was administered intravenous magnesium sulfate along with calcium gluconate. Remarkably, within three hours, all her symptoms resolved. While this case suggests that magnesium can provide relief from cramps and other neurological side effects, it is important to note that magnesium was used in conjunction with other medications, making it challenging to assess its isolated effectiveness.

For future doses, the oxaliplatin was adjusted by reducing the dose and extending the infusion duration, which minimized her symptoms to occasional mild paresthesia. In summary, while magnesium showed promise in this case, further research is needed to determine its specific impact on leg cramps in a clearer, more controlled manner.

Magnesium shows potential benefits
We explored the effectiveness of magnesium treatment for leg cramps during pregnancy through a review of five randomized trials involving 352 women.

The trials varied in quality, but interestingly, they included comparisons of different treatments such as calcium and sodium chloride against placebos. While the placebo-controlled trial that investigated calcium did not show any significant benefits, there were hints of promise for magnesium.

For those looking for relief from troublesome leg cramps, our analysis indicated that magnesium—specifically in the forms of magnesium lactate or citrate—might help. Taking 5mmol in the morning and 10mmol in the evening seemed to provide the best results.

However, the evidence remains mixed, and we couldn't pinpoint any strong benefits from other combinations or supplements tested. So, while magnesium might be beneficial, it’s essential to approach it as one option among many.

Magnesium oxide treats leg cramps
We conducted a study to evaluate how effective magnesium oxide monohydrate (MOMH) is in treating nocturnal leg cramps (NLC). This was a randomized, double-blind, placebo-controlled trial involving multiple centers in Ukraine, where participants took either MOMH or a placebo nightly for 60 days.

Our focus was on measuring the frequency and duration of cramps, the pain they caused, and how they affected sleep quality and overall life satisfaction. We used thorough statistical methods to compare the results between the two groups.

The findings indicated that MOMH is both effective and safe for individuals dealing with NLC. Participants reported improvements in their symptoms, demonstrating that this magnesium supplement can play a helpful role in managing nocturnal leg cramps.
We evaluated the effectiveness of magnesium supplements in preventing leg cramps, a common issue especially for older adults and pregnant women. Our focus was on randomized controlled trials that compared magnesium to placebos or other treatments.

After analyzing data from 11 trials involving a total of 735 participants, we found that magnesium supplementation showed little to no significant benefit. For older adults suffering from idiopathic leg cramps, the differences in cramp frequency, intensity, and duration were minimal and not statistically significant. In one trial focused on pregnant women, the results were mixed and not conclusive.

Additionally, while some participants did report minor gastrointestinal side effects from magnesium, major adverse events were not significantly different from those who received placebo. This leads us to conclude that magnesium may not provide meaningful relief for most older adults experiencing leg cramps. For pregnant women, further studies are necessary to determine if magnesium could be effective.

Overall, the evidence suggests that more research is needed to clarify magnesium's role, especially in specific populations like pregnant women who experience cramps.

Magnesium ineffective for leg cramps
We examined the effectiveness of magnesium supplements in reducing leg cramps during pregnancy, a common issue that affects up to half of pregnant women. Four randomized controlled trials were included in our analysis, with a total of 332 participants, which compared magnesium treatment to a placebo.

Our findings showed that magnesium supplementation did not significantly decrease the frequency of leg cramps compared to the control group. The weighted mean difference was -0.47, which indicates that while there may be a slight improvement, it was not considered statistically meaningful.

Moreover, magnesium did not help women recover from leg cramps more effectively than the placebo, and there were no significant side effects reported. Overall, we found that oral magnesium supplementation is not effective in treating leg cramps during pregnancy.
We observed the effectiveness of magnesium as a treatment for leg cramps during pregnancy, using data from several studies that included over 500 women. The research aimed to understand whether magnesium could help reduce the frequency and intensity of leg cramps, a common complaint among expectant mothers.

While some studies indicated that magnesium might help reduce the occurrence of leg cramps for some women, the results were inconsistent and did not show a clear benefit. In fact, for various outcomes measured, such as pain intensity and the total number of cramps, the evidence was not strong enough to draw firm conclusions. The studies varied in how they reported their findings, making it challenging for us to compile and compare the data effectively.

Additionally, the certainty of the evidence we found was rated as low to very low, largely due to the small size of the trials and some design limitations. Importantly, there were not enough data to assess the safety of magnesium or compare it adequately with other treatments. Overall, it appears that magnesium may not be the magic bullet for dealing with leg cramps in pregnancy, but more research could help clarify its role in the future.
We explored how magnesium might help alleviate leg cramps during pregnancy through a systematic review of six randomized controlled trials, involving 390 women in total. These studies compared magnesium with placebo or no treatment to see if it could reduce the frequency and intensity of these cramps.

Interestingly, the results showed mixed outcomes. While some trials indicated a slight reduction in the number of leg cramps after magnesium treatment, it wasn't consistent across the board. For example, one trial noted that magnesium could lead to a 50% reduction in cramps, while others found no significant difference compared to placebo.

We also observed that the overall quality of the evidence was low, mainly due to small sample sizes and design limitations. The studies did not comprehensively assess the safety of magnesium either, as side effects were only reported for magnesium versus placebo. Additionally, it was worth noting that other interventions like calcium and vitamin B were also tested but did not show a clear advantage over magnesium.

In conclusion, our findings leave us with an unclear picture of magnesium's effectiveness against leg cramps in pregnant women. For a more definitive answer, more rigorous studies are warranted, especially those exploring different methodologies, including non-drug therapies.
