We explored the impact of vitamin D3 levels on bone pain that patients experience after undergoing unicompartmental knee arthroplasty (UKA). The study involved 240 participants who were divided into three groups based on their vitamin D status—some received treatment before surgery, some after, and others had normal levels to begin with.
By administering vitamin D3 in three doses, we aimed to see if correcting deficiencies could alleviate post-operative bone pain. Throughout the recovery period, we measured pain levels using the visual analog scale at various intervals after the surgery.
Our findings clearly demonstrated that patients who corrected their vitamin D3 deficiency before surgery reported significantly better pain control after the operation compared to those who were treated afterwards or those who started with adequate levels. This highlights the importance of testing and addressing vitamin D status prior to orthopedic procedures, showing that it is a modifiable risk factor affecting recovery.

We investigated how choline magnesium trisalicylate (CMT) helps alleviate bone pain in patients with metastatic cancer. In a carefully designed study involving 26 participants, we compared CMT against a placebo in a crossover format, measuring pain relief at multiple intervals after dosing.
While we observed a significant reduction in pain just one hour post-treatment with CMT, other comparisons showed improvements that didn't reach statistical significance. This suggested that CMT might assist in managing bone pain, potentially complementing traditional opioids, but overall effectiveness is still under exploration.

We evaluated the effects of pamidronate therapy on children with osteogenesis imperfecta type III. Over the course of treatment, we saw reductions in bone pain, alongside a significant decrease in fracture incidence.
The therapy positively impacted children's daily activities and their overall mobility. Importantly, the treatment was found to be safe, although some patients experienced mild side effects like low calcium levels and a fever. Overall, our findings suggest that bisphosphonate therapy is beneficial for management in these young patients.

I found calcium to be very effective for my bones. After two months of back pain, despite massages and ointments, nothing worked until I began taking calcium on my doctor's advice. A week later, I realised my back pain had vanished. Additionally, my digestion improved significantly, with food digesting quickly, which is a nice bonus.

I've been using this calcium for 20 years and refuse to switch to another brand. My 84-year-old mother has been taking it for 16 years, and she has no issues with her bones. Her bone density remains commendable each time she is tested.

We conducted an insightful study to analyze how combining calcitriol, a form of vitamin D, with bisphosphonates affects bone pain in postmenopausal women suffering from osteoporosis. This quasi-experimental approach allowed us to compare two groups: one treated with calcitriol alone and the other with the combination treatment.
Our findings highlighted that adding bisphosphonates to calcitriol significantly alleviated bone pain among the participants. We observed improved evaluations of joint pain through the Visual Analogue Scale/Score, indicating that patients felt much better post-treatment. Furthermore, the combination therapy enhanced the patients' overall daily living capabilities and positively influenced bone metabolism and density.
Overall, our results suggest that calcitriol combined with bisphosphonates is effective in not just relieving pain but also supporting the long-term health of bones in postmenopausal women. This approach may pave the way for improved treatment strategies for osteoporosis in this demographic.

We investigated the connection between vitamin D levels and the risk of new vertebral fractures in postmenopausal women who had undergone percutaneous vertebral augmentation. Through a retrospective case-control study involving patients aged 50 and older, we analyzed records to categorize participants into groups based on whether they experienced refractures and how serum levels of 25-hydroxyvitamin D (25[OH]D) influenced these outcomes.
Our findings revealed that low levels of serum 25(OH)D are linked to an increased risk of new vertebral fractures in these patients. What's noteworthy is that vitamin D plays a crucial role in maintaining bone health, and adequate levels can help reduce the likelihood of subsequent fractures after surgery. This underscores the potential importance of vitamin D supplementation for patients recovering from vertebral augmentation.
In conclusion, ensuring that patients receive appropriate vitamin D intake might be pivotal in preventing further bone pain and fractures following surgery. By addressing vitamin D deficiency, we could significantly improve bone health outcomes and enhance the quality of life for postmenopausal women recovering from vertebral fractures.

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.

Promising drug delivery for osteoporosis
We developed a novel drug delivery system combining denosumab and magnesium within metal-organic frameworks to target osteoarthritis. The framework showed good potential for loaded drug release, delivering about 72% of denosumab in just 8 hours.
Additionally, it released magnesium ions, which are beneficial for bone formation. Our cytotoxicity tests demonstrated that the system is biocompatible and encourages cell growth over time. While our findings are promising for pain relief linked to osteoporosis, further studies are needed to confirm effectiveness in real-world scenarios.

The calcium quality is good with natural ingredients. At 41, the capsules helped improve my knee issues. My daughter, aged six, benefited as well, with her permanent tooth emerging after being expected for three months. This supplement compensates for deficiencies effectively, and the packaging is high quality.

Helps sleep better
1 people found this helpful
I really like this product and brand. After my ovaries were removed, I ensured I consumed plenty of calcium to keep my bones strong. I notice improved sleep when taking calcium/magnesium supplements. When I run out, I struggle to sleep, likely due to the magnesium's effects, which aid calcium absorption. However, excessive magnesium can lead to soft stools, so the balanced ratio in this formula is key.
