We explored the effectiveness of calcium in alleviating heartburn, especially in pregnant women. Our findings highlighted that many expectant mothers experience heartburn due to hormonal changes and the physical pressure of a growing fetus on the stomach.

Calcium-based antacids emerged as an excellent choice for providing relief. Not only do they help manage heartburn symptoms, but they also offer a source of calcium, which is vital for bone health in both mothers and their developing babies.

By ensuring adequate calcium intake through these antacids, we can support maternal health while addressing the discomforts of pregnancy. This dual benefit makes calcium supplementation a practical option for maintaining well-being during this critical time.

We explored how calcium phosphate (CaP) injections impact knee pain, particularly in patients suffering from osteoarthritis-related bone marrow lesions (OA-BML). In this study, we compared two groups of patients: those who received knee arthroscopy combined with CaP injections and those who had knee arthroscopy for different knee issues.

Our observations showed that patients receiving the CaP injections experienced less frequent conversions to total knee arthroplasty (TKA) when compared to the other group. Notably, within the CaP group, we noticed a significant improvement in their knee injury and functional outcome scores before and after the procedure. However, patients who only underwent knee arthroscopy did not show the same level of improvement.

Overall, we found that adding CaP injections during knee surgery for OA-BML significantly enhanced functional outcomes over traditional surgery alone. This study underscores the potential benefits of CaP treatments in managing knee pain and improving quality of life for those suffering from knee OA.

We investigated the potential of 2D layered calcium disilicide nanoparticles (CSNs) to treat rheumatoid arthritis (RA) through their unique properties. CSNs are crafted using a straightforward method of aqueous exfoliation, and their hydrolysis generates several beneficial components including hydrogen gas, alkaline calcium hydroxide (Ca(OH)), and silica.

These components support healing by improving anti-oxidation and reducing inflammation while promoting bone regeneration. The hydrogen gas helps eliminate harmful radicals and can alter macrophage behavior, which is crucial for regulating inflammation. Meanwhile, calcium hydroxide works to balance the acidic environment in the joints, limiting the harmful activity of osteoclasts, the cells that break down bone.

Furthermore, the calcium released can bind with phosphates, aiding in the formation of calcium phosphate, which is essential for bone mineralization. We confirmed these multifaceted benefits through tests on arthritic mice and rabbits, demonstrating that CSNs can provide a promising, biocompatible treatment strategy that enhances therapy beyond just addressing inflammation.

This study emphasizes the importance of calcium and its interactive role in more comprehensive arthritis treatments, fostering both anti-inflammatory and pro-osteogenic effects vital for joint health.

We explored the impact of calcium and vitamin D supplementation combined with sling core stabilization training on back pain in a 70-year-old female patient suffering from osteoporosis. The patient engaged in this form of exercise three times a week, focusing on strengthening the deep muscles of her spine.

After a year of dedicated training, not only did her back pain significantly improve, but a follow-up examination also indicated an increase in her bone mineral density. This suggests that the combined approach of exercise and supplementation might promote better bone health and potentially reduce pain.

However, it’s important to note that while we saw positive changes in this case, the specific contributions of calcium alone cannot be clearly identified due to the concurrent treatments involved. Therefore, we recognize that further studies are needed to isolate calcium's effects to conclusively determine its role in managing back pain effectively.

We explored the connections between calcium levels and kidney stones using data from the National Health and Nutrition Examination Survey (NHANES) spanning 2013 to 2018, along with more advanced genetic analyses. Our aim was to understand how the levels of 25-hydroxyvitamin D, calcium, and alkaline phosphatase (ALP) might influence the risk of developing kidney stones.

While observational analyses suggested a relationship between ALP levels and kidney stones, we found that calcium levels did not display a significant association with kidney stones when looking at the data directly. However, utilizing Mendelian randomization analysis, we observed a potential causal link, indicating that elevated calcium levels could indeed raise the risk of developing kidney stones.

The key takeaway from our research is that while observational studies show no strong link between calcium and kidney stones, our genetic analysis implies that higher calcium may contribute to stone formation. Our work provides valuable insights and directions for future studies focused on preventing and treating this painful condition.

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 how calcium intake relates to constipation, particularly focusing on individuals with metabolic syndrome, a condition that significantly impacts health. Using data from the National Health and Nutrition Examination Survey conducted between 2005 and 2010, we assessed the dietary habits of participants and looked at how often they experienced constipation.

Our findings suggest a noteworthy connection: as dietary calcium intake increases, the risk of constipation decreases among those with metabolic syndrome. This suggests that calcium could play a beneficial role in gastrointestinal health.

By analyzing dietary recalls and bowel movement frequency, we provided valuable insights into how making dietary changes can potentially improve symptoms for those affected by metabolic syndrome. This emphasizes the importance of dietary calcium as a simple yet impactful strategy for managing gastrointestinal issues in this specific population.

Our research explored the effects of a new calcium-loaded complex, made from Antarctic krill protein and enriched with pectin, on calcium absorption and bone health in mice with calcium deficiency. We created a model that simulated calcium deficiency, which is a significant concern as it can contribute to osteoporosis.

We observed that chronic calcium deprivation led to decreased calcium absorption and deterioration of bone structure. However, the P + Ca + HMP complex significantly improved calcium retention and increased the strength of the femur, indicating a positive impact on bone health.

Additionally, this complex improved the structure of the trabecular network, which is essential for maintaining strong bones. The presence of beneficial bacteria in the gut also rose after the intervention, and these were linked to better calcium absorption and bone synthesis. Overall, these findings point to the potential of the P + Ca + HMP complex as an effective calcium supplement that could help prevent calcium deficiency and thus support bone health.

We explored the impact of calcium treatment on bone pain in patients who developed osteomalacia, a condition linked to intravenous iron infusions. Our focus was on a group of 13 patients diagnosed with this condition, who experienced low phosphate levels due to excess fibroblast growth factor 23 (iFGF23) after receiving ferric carboxymaltose (FCM) infusions.

After halting the FCM infusions, these patients were given supportive treatment, which included phosphate, calcium, and active Vitamin D supplementation. We observed improvements in biochemical markers, including increased phosphate levels and reduced pain scores. However, it’s important to note that while calcium was part of the treatment regimen, we could not isolate its specific effects on bone pain from the other supportive measures used.

Ultimately, our findings highlight the importance of monitoring phosphate levels in patients receiving FCM, and stopping these infusions effectively addresses phosphate wasting. Although supportive treatment showed improvements in pain and bone density, the direct impact of calcium on bone pain remains unclear given the combination of treatments involved.

We conducted a study to investigate how calcium maltobionate affects bone density in healthy Japanese women, particularly focusing on those who are pre- and post-menopausal. In a well-structured trial, 48 women aged between 30 and 69 were randomly divided into two groups: one received calcium maltobionate tablets while the other took a placebo designed to mimic the calcium content.

Over 24 weeks, we measured changes in facial and calcaneal bone density along with bone resorption markers. Our results indicated that facial bone mineral density declines more rapidly than that of other areas like the lumbar spine. Importantly, we observed that continuous intake of calcium maltobionate helped to slow down this decline in bone density for women in both menopausal stages, suggesting its potential role in osteoporosis prevention.

Overall, we found that facial bone mineral density may serve as an important indicator of bone health in middle-aged women. While our study highlights the beneficial aspects of calcium maltobionate, it’s essential to note that the individual effects of calcium itself could not be isolated from the compound used in the treatment.

We explored the effects of calcium deposition in the rotator cuff tendons on frozen shoulder, particularly in cases where calcific tendinitis was present. The study involved 32 patients who underwent a specialized procedure combining arthroscopic brisement of the shoulder joint with multiple punctures at the calcific site. This innovative approach aimed to alleviate the pain and restore mobility linked to frozen shoulder.

After following up with the patients for two years, we observed that 30 out of 32 patients reported satisfactory outcomes. While five individuals still showed some postoperative calcium deposits, many experienced significant improvements in their range of motion and relief from pain. This suggests that combining treatment methods can enhance recovery, although we recognize that the isolated effect of calcium treatment alone remains unclear.

Overall, this study contributes valuable insight into managing frozen shoulder, especially when associated with calcific tendinitis, even if it doesn't fully isolate the impact of calcium treatment.

I was informed that calcium and magnesium should be taken together, so I opted for this product despite its somewhat high cost for health reasons. When I first took it, I noticed some loosening in my muscles, although my frozen shoulder does seem to tighten again due to lack of exercise. Nevertheless, I believe it’s more beneficial to take these than not at all.
