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.

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.

I tried different versions of magnesium, and this one is perfect for a sensitive stomach. It has no laxative effect and helps with nocturnal cramps in my legs. The pills are medium-sized, easy to swallow, and have a slight sweetness. They effectively fulfil their purpose. While on the KETO diet, I take three daily and find I wake up more refreshed. After a month, my blood tests showed excellent absorption levels. I plan to buy this again!

Effective for cramps
5 people found this helpful
Magnesium Malate is the only supplement I’ve found that effectively addresses cramps and supports heart health. A researcher noted that, regarding magnesium products available over the counter, "one would be better off eating a handful of dirt." The Malic Acid in this product aids absorption significantly within the small intestine. The potency of these tablets ensures that even older individuals with absorption issues like myself find relief. Magnesium is key to balancing electrolytes that, when unbalanced, cause painful leg cramps. This supplement has also helped with my Paroxysmal Atrial Fibrillation. I previously endured months of crippling cramps, but now, thanks to my research and determination, I’ve found lasting relief by taking 6 tablets daily.

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 investigated the effectiveness of oral magnesium supplementation in reducing leg cramps among pregnant women. In a controlled clinical trial with 132 participants, we compared the impact of 300 mg/day of magnesium citrate against a placebo.

Most participants experienced multiple leg cramps each week, and after four weeks, we recorded a notable reduction in leg cramps overall—28.4% across all women. However, when looking closely, we found no significant difference between the magnesium group and the placebo group. The placebo group even reported a slightly higher percentage of reduction in cramps (32.8% versus 27.2% for magnesium).

We also looked at the side effects and found that four women reported mild gastrointestinal issues, but these were not serious. Overall, the results suggest that oral magnesium supplementation does not significantly improve leg cramps during pregnancy, raising questions about its effectiveness for this purpose.
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.
