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.

Calcium magnesium does wonders for cramps! I suffered from excruciating cramps during my period for years. After starting this cal/mag supplement (2 in the morning, 2 at night), the results have been astounding! I haven't experienced a single leg cramp since I began. Without it, I would previously spend all day in bed with cramps. Now, I feel free to engage in daily activities!

Calcium's unclear role in cramps
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
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.

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.

Effective for cramps

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!

Supports bone health
I've been using this calcium regularly, taking 4 tablets daily. The capsules are smooth enough for easy swallowing. I started taking it to prevent osteoporosis due to my age, and my bone density remains stable. My legs feel strong, and the inclusion of magnesium and vitamin D is advantageous. I highly recommend it for its quality and affordability.
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
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.
