Top Medical Research Studies

We designed a multicenter, double-blind, placebo-controlled trial to explore if vitamin K2 can effectively manage nocturnal leg cramps (NLCs).

Conducted in China with older adults experiencing regular cramps, participants were randomly assigned to receive either vitamin K2 or a placebo for 8 weeks. Remarkably, our findings demonstrated that vitamin K2 significantly reduced the frequency, duration, and intensity of NLCs, making it a promising option for those suffering from this discomfort.

Notably, the treatment showed good safety profiles, reinforcing its potential utility in managing leg cramps.

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.

Cramps disappeared

This product is excellent, made from green plants with antioxidants and phytonutrients. The ingredients are healthier than any other calcium product I've used. My leg cramps have vanished since I began taking it, as it relaxes muscles and provides sufficient calcium during sleep.

This is the best calcium supplement! It has D-3 for better absorption and K-2 to direct calcium where it’s needed. The amount of magnesium is perfect, so no extra is required. After switching from another brand during my second pregnancy, I experienced no leg cramps or bone pain this time. I highly recommend this to everyone, especially during pregnancy or breastfeeding.

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.

Cramps improved

I love this calcium. My mother had parathyroid issues, and we monitor her parathyroid hormone levels. After taking this calcium, we normalised her symptoms. The inclusion of K-2 is beneficial for absorption into bone tissue. It's essential to take it with D-3, at least 5000 IU, preferably in the evening. If you're experiencing leg cramps, be sure to include magnesium as well.

Frequently Asked Questions

Reduced leg cramps
It’s unfortunate that this supplement was banned in Russia. I purchased it to increase my calcium intake during pregnancy, as I suffered from leg cramps at night. After just two days of use, my cramps stopped. Magnesium has a calming effect; I fall asleep as soon as my head hits the pillow. The combination of calcium, magnesium, vitamins C, D, and K is excellent for absorption. Calcium gets directed where needed. I highly recommend it.

Calf cramps resolved

I have been breastfeeding for over 10 months and was concerned about calcium leaching and calf cramps. Initially, I took 2 capsules a day, but that wasn't enough. Now, I take the recommended full dosage and have found relief from the cramps. A very effective product.
