Magnesium reduces pregnancy leg cramps
Oral magnesium for relief in pregnancy-induced leg cramps: a randomised controlled trial.
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
Randomised, cross-over, placebo controlled trial of magnesium citrate in the treatment of chronic persistent leg 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.

Effective magnesium. I bought this for the first time and I'm very pleased. I took it in the afternoon, and leg cramps and muscle tension have disappeared.
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.

Overall, we believe magnesium shows promise in alleviating nocturnal leg cramps and recommend further research to fully evaluate its effectiveness.
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.
Works great! All other magnesium gave me diarrhoea, but this one works wonderfully. I love how it helps with leg cramps and restless legs.

Leg cramps, often referred to as "charley horses," are sudden, involuntary contractions of one or more muscles in the leg. They typically occur in the calf muscles but can also affect the thighs and feet. These cramps can be quite painful and may last from a few seconds to several minutes. While the exact cause of leg cramps is not always clear, they can be triggered by factors such as dehydration, prolonged sitting or standing, electrolyte imbalances, or physical activity, especially in those who are not used to vigorous exercise.
Treatment for leg cramps often involves stretching the affected muscle gently, applying heat or cold to the area, and ensuring adequate hydration. For some, dietary adjustments to include more potassium, magnesium, and calcium may help prevent future occurrences. If cramps are frequent or severely debilitating, it may be beneficial to consult a healthcare provider for a more tailored approach. Understanding the underlying causes of leg cramps can lead to more effective management strategies, improving overall comfort and mobility.
Magnesium is a chemical element with the symbol Mg and atomic number 12. It is a lightweight, silvery-white metal that is a member of the alkaline earth metals group. Often classified as one of the most abundant elements in the Earth's crust, magnesium plays a crucial role in various biological functions and is essential for living organisms. In nature, magnesium can be found in large quantities, primarily in minerals such as dolomite and magnesite, and it is also present in seawater.
In terms of health benefits, magnesium is vital for numerous metabolic processes, including energy production, DNA synthesis, and muscle function. It contributes to bone health, helps regulate blood pressure, and supports bone formation by promoting the effects of vitamin D. The recommended dietary allowance (RDA) for magnesium varies by age and gender, but it is generally important to include magnesium-rich foods like leafy greens, nuts, seeds, and whole grains in your diet to ensure adequate intake. For those who may not receive enough magnesium through their diet alone, supplements are also available; however, it is advisable to consult a healthcare professional before starting any supplementation.
Magnesium has been noted for its potential role in alleviating leg cramps, particularly in individuals who experience nocturnal leg cramps or muscle spasms. As an essential mineral, magnesium contributes to muscle function and helps regulate muscle contractions. Some studies suggest that supplementing with magnesium may lead to a decrease in the frequency and intensity of leg cramps, especially in populations at risk for magnesium deficiency, such as older adults or those with specific health conditions.
That said, while magnesium supplementation could be beneficial, it's always a good idea to consult with a healthcare professional before starting any new supplements. They can provide personalized advice based on your health history and dietary needs. Moreover, ensuring a balanced intake of nutrients, staying hydrated, and maintaining regular physical activity can also play significant roles in managing leg cramps effectively.
Based on user reviews, many individuals report experiencing significant relief from leg cramps after starting this magnesium supplement, often within a short period. Users like those identified in Read Review and Read Review have noted that their leg cramps disappeared relatively quickly after they began taking the capsules. Similarly, another user mentioned cessation of cramps shortly after starting the supplement, referring to it as effective and convenient Read Review.
However, a few reviews suggest that while the impact is often immediate, continuing to take the supplement regularly may be necessary to maintain its benefits. For instance, one user highlighted that once they stopped taking it, the cramps returned within a couple of days Read Review. Overall, it seems that while some users notice improvements within days to weeks, consistent usage appears to be key for long-term relief.
Magnesium supplementation is often touted as a potential remedy for leg cramps, but the scientific support for its effectiveness is mixed. A randomized, double-blind, placebo-controlled trial involving magnesium oxide monohydrate (MOMH) indicated that it can be effective and safe for managing nocturnal leg cramps, showing improvements in symptoms among participants [1]. In contrast, several studies specifically targeting pregnant women revealed inconsistent results. An analysis of multiple trials found that magnesium did not significantly reduce the frequency or intensity of leg cramps compared to placebos, often showing only minor improvements that were not statistically meaningful [2], [3], [5].
Overall, while some studies suggest a potential benefit of magnesium, particularly in some cases of nocturnal leg cramps, the evidence, especially concerning its use during pregnancy, remains unclear and varied across studies. Many trials exhibited low-quality evidence with small sample sizes and design limitations, indicating a need for further rigorous research to draw firm conclusions about magnesium's role in treating leg cramps [8]. Thus, if you're considering a magnesium supplement for leg cramps, it may be worth consulting with a healthcare provider to discuss its potential benefits and whether it’s appropriate for your needs.
Users report a significant improvement in their leg cramps and overall muscle tension after incorporating this magnesium supplement into their daily routine. Many individuals, such as those in Read Review and Read Review, highlight that their leg cramps have completely disappeared, often within a short period of starting the supplement. Furthermore, users like the one identified in Read Review have noted that not only did their cramps diminish, but their overall feeling of well-being improved as well, with reports of enhanced sleep quality Read Review.
Moreover, several reviewers mentioned enhanced muscle recovery and reduced tension, indicating potential benefits beyond just alleviating cramps. For instance, one user remarked on experiencing fewer cramps during workouts and better sleep Read Review. While individual results can vary, many users consistently find that regular use of the supplement leads to noticeable improvements in both muscle comfort and sleep quality, underscoring the importance of ongoing intake to maintain these benefits Read Review. Overall, experiences suggest that incorporating this supplement could lead to significant relief from cramps and associated discomfort.

Additionally, a user remarked that the extended-release formulation aids in muscle recovery and reduces cramps during workouts, suggesting that this supplement works synergistically with an exercise routine Read Review.
While many users found extensive benefits from just the magnesium alone, some suggested that long-term usage is essential for sustained results. For example, one user mentioned that once they stopped taking the supplement, their cramps returned within a few days Read Review. Overall, the consensus among user reviews indicates that this magnesium can work effectively either standalone or in conjunction with other supplements or lifestyle changes, offering a holistic approach to managing leg cramps and muscle tension.
Users report that taking 1 capsule of magnesium daily is a common and effective dosage for alleviating leg cramps. Many reviews highlight positive results from this dosage, with several users noting that their leg cramps have significantly diminished or completely disappeared after consistent use. For instance, one user mentioned taking one capsule at lunch and another at night, which resulted in reduced night cramps and an overall sense of calmness Read Review. Another user indicated that even a single daily capsule was sufficient to experience relief from leg cramps Read Review.
While the consensus appears to support a daily capsule as an effective regimen, some reviews advise caution regarding the dosage's consistency, as the relief may diminish shortly after discontinuation Read Review. Overall, users seem to have a favorable experience with magnesium, often praising its added benefits such as improved sleep and reduced muscle tension Read Review.

Magnesium ineffective for leg cramps
Effect of oral magnesium supplementation for relieving leg cramps during pregnancy: A meta-analysis of randomized controlled trials.
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.

Magnesium does not reduce leg cramps
Oral magnesium supplementation for leg cramps in pregnancy-An observational controlled trial.
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.
