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.

This product works for the whole family. I noticed that my leg cramps have completely ceased. I used to have knee issues that manifested as crunching noises, but now I have no problems at all. I've not experienced any dental issues over the past year and feel much calmer overall.
We observed an interesting case regarding the effects of calcium treatment on leg cramps related to a chemotherapy drug called oxaliplatin. In this case, a 62-year-old woman undergoing palliative treatment for stage IV colon cancer experienced acute neurotoxicity symptoms. Notably, thirty minutes after her first infusion of oxaliplatin, which she received in her left arm, she developed cramps and paresthesia in her right leg.
As part of her treatment for these symptoms, intravenous calcium gluconate was administered alongside magnesium sulfate. This combination helped alleviate her leg cramping and associated symptoms within three hours. However, while calcium was part of the treatment regimen, it is important to note that its isolated effectiveness on leg cramps is unclear due to its concurrent administration with magnesium.
Consequently, while we saw improvement in the patient's symptoms, it is difficult to attribute these results solely to calcium. Instead, it suggests that magnesium might be playing a significant role as well. Future investigations could help clarify the specific contributions of calcium in treating leg cramps related to neurotoxicity and other conditions.

Calcium dobesilate reduces leg cramps
Calcium dobesilate for chronic venous insufficiency: a systematic review.
We examined the benefits of calcium dobesilate for patients suffering from chronic venous insufficiency (CVI), particularly focusing on how it impacts symptoms like leg cramps. In a systematic evaluation of ten different clinical trials involving 778 patients, we compared the effects of calcium dobesilate to a placebo.
Our analysis found that calcium dobesilate significantly reduced night cramps, helping patients nearly twice as much as those who received a placebo. The number needed to treat for this relief was calculated to be 8, indicating that for every eight patients treated with calcium dobesilate, one experienced noticeable improvement.
Moreover, patients also reported less discomfort, with a number needed to treat of 4 for that symptom. Interestingly, we noted that those with more severe symptoms experienced even greater relief, suggesting that calcium dobesilate is particularly effective for patients with advanced CVI. However, both doses tested—1,000 mg and 1,500 mg—proved equally effective, which is good news as it suggests that a lower dose might suffice.
Additionally, we found that adverse events were not significantly different from the placebo group, indicating a favorable safety profile. While calcium dobesilate shows promise, we acknowledge the need for further studies to solidify these findings and explore its efficacy in various CVI stages.

Calcium relief for leg cramps uncertain
Growth Hormone Deficiency in an Adolescent With Pseudohypoparathyroidism Type 1B.
We explored the impact of calcium treatment on leg cramps in an adolescent diagnosed with pseudohypoparathyroidism type 1B. The patient experienced symptoms such as muscle cramps and leg pain during activities, with laboratory tests revealing hypocalcemia and an elevated parathyroid hormone level.
While calcium treatment was part of a combined therapy that included other medications, we observed that the muscle cramps and hypocalcemia resolved after administering calcium carbonate, ergocalciferol, and calcitriol. However, due to the combination of treatments, it is challenging to determine the isolated effect of calcium on the leg cramps specifically.
Ultimately, while calcium contributed to symptom relief, our study does not provide conclusive evidence on its effectiveness alone for alleviating leg cramps. This highlights the need for further investigation into how calcium might individually influence leg cramp symptoms in such patients.

I used to suffer from nightly leg cramps, but since using this product as directed, they are no longer a problem.
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.
Calcium magnesium refers to a dietary supplement that combines two essential minerals, calcium and magnesium, which play critical roles in maintaining various bodily functions. Calcium is vital for building and maintaining strong bones and teeth, while magnesium supports muscle function, energy production, and the regulation of calcium levels in the body. Together, these minerals work synergistically to promote overall health, particularly in areas such as bone density, cardiovascular health, and muscle function.
Supplements that contain both calcium and magnesium can be particularly beneficial for individuals who may be deficient in these minerals due to dietary restrictions or health conditions. They are available in various forms, including tablets, capsules, and powders. When considering a calcium magnesium supplement, it's essential to choose a product with the right ratio of these minerals, as well as other supporting vitamins and minerals like vitamin D, which enhances calcium absorption. Always consult with a healthcare provider before starting any new supplement regimen to ensure it aligns with your health needs and goals.
Leg cramps can be a painful and disruptive experience, often occurring at night or after physical activity. Some studies and anecdotal evidence suggest that calcium and magnesium may play a role in reducing the frequency and severity of leg cramps. Calcium is essential for muscle contraction, while magnesium helps with muscle relaxation. A balanced intake of both minerals can potentially lead to better muscle function and decreased cramping. However, it’s important to note that while supplementation might help, it should ideally be combined with a well-rounded diet and good hydration practices.
Before starting any supplementation regimen, it’s prudent to talk to a healthcare professional, especially if you are experiencing frequent leg cramps or have underlying health conditions. They can provide personalized advice and help determine if a deficiency in calcium or magnesium is contributing to your cramps. If you're considering taking supplements, look for a product that offers a balanced ratio of both minerals and ensure that you also maintain regular physical activity and avoid dehydration to further mitigate cramps. Ultimately, the efficacy of calcium and magnesium in alleviating leg cramps may vary from person to person, and lifestyle changes may also play a significant role.
Based on user reviews, it typically takes a few days to a month to see noteworthy improvements when taking calcium and magnesium supplements for leg cramps. For instance, one user noted that after just one month of using the product, their leg cramps had disappeared completely and they experienced an overall reduction in discomfort during weather changes Read Review. Another review suggested that within a relatively short period of starting the supplement, they had not experienced any leg cramps and were finally able to engage in daily activities without pain Read Review.
Other users indicated a quicker onset of relief, mentioning the complete cessation of cramps after just a few days of taking the supplement Read Review. Overall, while individual experiences may vary, many users report that they start to feel the effects relatively quickly, often within one month, making these supplements a worthwhile consideration for anyone suffering from leg cramps.
When it comes to using supplements for alleviating leg cramps, the scientific research appears to present a mixed picture, particularly for common supplements like Vitamin D and magnesium. Several studies, including a randomized controlled trial involving 126 pregnant women, showed that neither Vitamin D nor its combination with calcium significantly reduced leg cramps, indicating limited efficacy for this use [2]. Evidence surrounding calcium’s effectiveness is similarly inconclusive; while some studies hint at a potential benefit, the overall benefit is classified as low quality and requires cautious interpretation [1].
On the other hand, magnesium supplementation has garnered attention for its potential effects in various populations, including pregnant women. Some studies demonstrate slight improvements; yet, many highlight that the effects are not statistically significant or are overshadowed by placebo effects [16]. For those specifically dealing with pregnancy-related leg cramps, magnesium citrate has shown some promise in terms of reducing discomfort, but the variability in study designs and outcomes suggests that consumers should remain wary and seek professional advice [21]. Overall, while common supplements like vitamin D and magnesium are explored for leg cramps, the current scientific consensus indicates that their effectiveness may be limited, and further research is essential to determine their true value.
Users have reported significant improvements in their symptoms after using calcium and magnesium supplements, particularly in alleviating leg cramps and related discomfort. Many individuals noted a complete cessation of cramps, allowing them to engage in daily activities without pain. One user stated that they had suffered from severe cramps during their period for years, but after starting the supplement, they experienced astounding results, with no cramps at all Read Review. Another mentioned that they had not experienced muscle cramps since starting the supplement, highlighting its effectiveness Read Review.
Additionally, improvements in overall comfort and a sense of well-being have been reported, with some users expressing enhanced sleep quality and reduced stiffness as a result of taking the supplements Read Review. Others have shared that they notice fewer arthritis attacks and improved resilience to stress Read Review. While these anecdotal experiences are encouraging, it is important to note that individual results can vary, and what works for one person may not yield the same results for another.
Users have frequently reported positive experiences when combining calcium and magnesium with other supplements, particularly vitamin D. Several reviews highlight that the addition of vitamin D to calcium and magnesium formulations has enhanced their effectiveness. For instance, one user noted a dramatic improvement in cramping and stiffness when using a calcium magnesium product that included vitamin D, recommending it for others with similar issues Read Review. Similarly, another individual experienced relief from nightly foot cramps, attributing part of their success to the optimal nutrient balance found in their chosen supplement Read Review.
Moreover, users have emphasized that the timing and method of consumption can also play a crucial role in alleviating cramps. For example, taking the supplement at bedtime helped one user notice a significant improvement in not only leg cramps but also sleep quality Read Review. Overall, the combination of these minerals and vitamins appears to leverage the benefits of synergistic effects, promoting better muscle function and reducing the incidence of cramps across various scenarios. While individual results may vary, many have found success in blending these supplements to enhance their overall efficacy for leg cramps.
Based on user reviews, finding the right dose of Calcium Magnesium for treating leg cramps varies among individuals, but many have reported significant relief with consistent usage. One user found success with taking 2 capsules in the morning and 2 at night, resulting in a remarkable decline in cramps that previously hindered daily activities Read Review. Others have mentioned that a regime of just 4 capsules a day has proven effective, alleviating muscle cramps and providing additional benefits like improved sleep quality Read Review.
Additionally, the magnesium to calcium ratio appears influential in enhancing effectiveness for some users. For example, one reviewer specifically noted that the proper nutrient balance effectively helped her mother who suffered from cramps due to dehydration Read Review. Overall, users recommend a dosage of 4 capsules a day while acknowledging some may start with lesser amounts to gauge their tolerance before adjusting upwards. Consistency seems key, as several users experienced a reduction in leg cramps upon integrating this supplement into their daily regimen.

Honest verified review, put 👍 if it was helpful! After consulting a nutritionist, I discovered I have a deficiency of calcium and vitamin D. To support my body during stress, I was advised to take magnesium. This supplement contains all the necessary components, with precise dosages for women. The only downside is the requirement of 4 capsules a day, which lasts about 3 months. I tried dissolving them in water, but it settled rather unpleasantly. A month later, the visible result—my leg cramps disappeared. I no longer experience discomfort in my legs with changes in weather, and my stress resilience has improved, especially with two children!

Vitamin D ineffective for cramps
The effect of Vitamin D and calcium plus Vitamin D on leg cramps in pregnant women: A randomized controlled trial.
We conducted a double-blind, randomized controlled trial to explore whether Vitamin D and calcium-Vitamin D supplements could help reduce leg cramps in pregnant women. Our study involved 126 participants aged 18 to 35, all experiencing a minimum of two leg cramps per week. Over the course of 42 days, participants took either a Vitamin D pill, calcium with Vitamin D, or a placebo.
We closely monitored the frequency, duration, and intensity of leg cramps before the intervention and during the third and sixth weeks of treatment. Despite our efforts and careful analysis, the results were clear: neither the Vitamin D nor the calcium-Vitamin D supplements made a meaningful difference in leg cramps.
This finding indicates that these popular supplements may not be effective for alleviating leg cramps during pregnancy, at least within the timeframe of our study. It's important for expecting mothers to consider this information when seeking relief from leg cramps.
We assessed the impact of vitamin D on leg cramps experienced during pregnancy, referring to data from various studies. One of the key findings was that vitamin D treatment showed little to no difference when it came to reducing the frequency of leg cramps.
In a trial involving 84 women, participants who received vitamin D did not see significant changes in the frequency of leg cramps after three weeks or six weeks post-treatment. This suggests that, while vitamin D is often discussed in the context of health benefits, its effectiveness for leg cramps specifically might be quite limited.
Overall, the evidence we reviewed highlights the need for caution. The findings suggest that vitamin D may not be a viable treatment option for managing leg cramps during pregnancy, indicating a need for more robust research in this area.
We examined the effectiveness of magnesium supplementation for preventing skeletal muscle cramps through a systematic review of several studies. Seven trials involving a total of 406 participants were included, with some studies focusing on women experiencing leg cramps during pregnancy and others on adults with idiopathic cramps.
Overall, we found that magnesium supplementation did not offer a significant benefit in reducing the frequency or intensity of cramps for older adults. The data on idiopathic cramps showed only minor changes that weren’t statistically significant. Specifically, the difference in the number of cramps per week between magnesium and placebo groups was negligible, suggesting that it may not provide any clinically meaningful relief.
For pregnant women experiencing leg cramps, the results were mixed, indicating a need for further research. It’s clear from the trials that magnesium might not be the miracle solution that many hope for when it comes to leg cramps. We also noted that any side effects reported were similar to those seen with placebo, reinforcing the idea that magnesium poses little risk.

Magnesium aids pregnancy leg cramps
The effect of oral magnesium substitution on pregnancy-induced leg cramps.
We examined whether oral magnesium supplementation could help women suffering from pregnancy-related leg cramps. In a careful study involving 73 participants, we used a double-blind method where half received magnesium and the other a placebo for three weeks.
While magnesium didn’t significantly boost serum levels, we found that those taking it experienced less distress from leg cramps compared to the placebo group. This suggests that magnesium could be a helpful option for managing cramps during pregnancy.
