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.

A wonderful complex of minerals! I’m amazed by the effect! At 39, my legs often hurt and felt heavy after walking. After a month of taking this, the pain disappeared completely! I take it in cycles, drinking for a month and then resting for a month. I hope my honest feedback helps others.

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.
