Magnesium treats anxiety in MS
Nanoparticulate MgH ameliorates anxiety/depression-like behaviors in a mouse model of multiple sclerosis by regulating microglial polarization and oxidative stress.
Most Relevant Research
We aimed to understand the impact of nanoparticulate magnesium hydride (MgH) on anxiety and depression associated with multiple sclerosis (MS). Our exploration involved studying how MgH affects mood disorders in a model we designed, specifically using experimental autoimmune encephalomyelitis (EAE) mice.

We discovered that MgH treatment significantly alleviated anxiety and depression-like behaviors in these mice. Not only did MgH help improve their mood, but it also reduced overall disease severity and inflammatory damage within the central nervous system.

Importantly, our findings suggest that MgH could be working by promoting healthier microglial activity. It appears to encourage the beneficial M2 polarization while inhibiting the harmful M1 polarization, alongside reducing oxidative stress. This mechanism offers a glimpse into how magnesium might truly enhance well-being for those dealing with MS-related psychiatric issues.

In summary, our research indicates that nanoparticulate MgH holds promise as a non-toxic and effective treatment option for anxiety and depression in people suffering from MS, showcasing a potential breakthrough in managing these debilitating conditions.

Magnesium supplementation aids chest pain
The prevalence of hypomagnesaemia in pediatric patients with mitral valve prolapse syndrome and the effect of mg therapy.
Most Relevant Research
We explored the effects of magnesium treatment on chest pain in pediatric patients suffering from mitral valve prolapse syndrome. In our study involving 230 young participants, we defined hypomagnesaemia as having a serum magnesium level below 1.5 mg/dl.

After identifying 19 patients with insufficient magnesium levels—representing about 8.2% of the group—we treated them with an oral magnesium chloride supplement for five weeks. We were eager to see whether this would help alleviate symptoms, particularly chest pain.

After the treatment period, we observed that magnesium therapy provided statistically significant relief of chest pain for these patients. However, we did not find substantial improvements in other symptoms like palpitations, fatigue, and dyspnea. This finding is vital, as it indicates that while magnesium may play a role in easing chest pain, its overall benefit to other symptoms remains uncertain.

Overall, our study highlights the relatively low prevalence of magnesium deficiency in pediatric patients with mitral valve prolapse compared to adults. Nevertheless, we concluded that magnesium supplementation could be a beneficial approach to address specific symptoms like chest pain in this population.

Magnesium deficiency affects diabetes control
Hypomagnesemia in adults with type 2 diabetes mellitus in Riyadh, Saudi Arabia: A cross-sectional study.
Most Relevant Research
We looked into how magnesium levels relate to diabetes, specifically focusing on adults with type 2 diabetes mellitus (T2DM) in Riyadh, Saudi Arabia. Conducted as a cross-sectional study, we analyzed data from 294 individuals, including T2DM patients, prediabetics, and nondiabetic controls. Our goal was to uncover the prevalence of magnesium deficiency and its potential effects on various metabolic factors.

The findings revealed a striking difference in magnesium levels across the groups. T2DM patients exhibited notably lower magnesium than those with prediabetes and nondiabetic controls. This deficiency was linked to worse metabolic outcomes, including higher fasting glucose and glycated hemoglobin (HbA1c) levels, as well as increased insulin resistance.

We noted a strong negative correlation between magnesium levels and both glucose and HbA1c, suggesting that as magnesium levels decrease, diabetes control worsens. Interestingly, our analysis indicated that magnesium levels could effectively predict higher HbA1c values, highlighting the need for regular monitoring of magnesium in diabetes management.

While our study emphasizes the significant impact of magnesium deficiency on the metabolic health of T2DM patients, it also opens the door for further exploration regarding the benefits of magnesium supplementation in diabetes care. Overall, these insights push us to consider the broader implications of maintaining proper magnesium levels for better diabetes management.

Magnesium protects against bone erosion
Serum ionized magnesium acts as an independent protective factor against bone erosion in patients with gouty arthritis: a cross-sectional study.
Most Relevant Research
We delved into the relationship between magnesium levels and gouty arthritis, a condition known for causing painful flare-ups and damaging joint function. Our research focused on measuring serum ionized magnesium levels in a group of 769 patients and assessing how these levels relate to bone erosion, a serious complication of gout.

Our findings revealed that patients experiencing bone erosion had significantly lower magnesium levels compared to those without erosion. When we categorized magnesium levels into quartiles, the data showed that those in the lowest quartile (Q1) were more likely to have bone erosion compared to patients in higher quartiles. In fact, the prevalence of erosion in the lowest magnesium group was much higher, illustrating a clear connection.

Through detailed analysis, we concluded that higher levels of serum ionized magnesium may serve as a protective factor against bone erosion in gouty arthritis. This suggests that magnesium supplementation could be a promising strategy for individuals suffering from this debilitating condition, potentially helping to slow down or prevent further joint damage.

Effect of perioperative intravenous magnesium sulfate on postoperative pain after iliac venous stenting.
Most Relevant Research
We explored the effectiveness of magnesium sulfate (MS) in relieving low back pain (LBP) for patients who underwent iliac venous stenting. This study involved 97 patients, divided into two groups: one received MS infusion during their surgery, while the other did not.

Patients who received MS experienced significantly lower pain levels at all follow-up intervals. We found that, at 24 hours after surgery, those in the magnesium group consumed much less tramadol—a common pain medication—compared to the control group. Additionally, the need for extra pain relief was lower among those who received magnesium.

Importantly, the side effects like nausea and vomiting were similar in both groups, indicating that magnesium can be a safe option for pain management after this type of surgery. Overall, the findings suggest that magnesium sulfate not only alleviates pain but also reduces reliance on opioids, making it a valuable treatment for postoperative care.

Magnesium reduces bruising post-surgery
The Efficacy of Magnesium Sulfate (MgSO4) Wet Dressing in Reducing Eyelid Swelling and Bruising after Blepharoplasty: A Randomized, Controlled, and Observer-Blinded Assessment Study.
Most Relevant Research
We explored the impact of magnesium sulfate (MgSO4) wet dressings on bruising and swelling following blepharoplasty, a common eyelid surgery. In our study, fifty-eight patients were evenly split between two treatments: one side received a magnesium sulfate solution, while the other was cooled with ice packs. This setup allowed us to compare the effectiveness of these two methods objectively.

Over the recovery period, we observed that the eyelid swelling was similar in both groups initially but notably reduced over time. However, by the fifth day after surgery, we found that those treated with the magnesium solution experienced significantly less swelling compared to the cooling method. Additionally, bruising—measured by both area and incidence—was also lower in the magnesium group, highlighting its effectiveness.

Interestingly, a significant majority of patients preferred the magnesium treatment over ice cooling, with many appreciating the convenience and results of the wet dressing. This suggests that magnesium sulfate is not only effective in reducing bruising and swelling but is also a patient-favored option for recovery after eyelid surgery.

Magnesium alloy inhibits cancer growth
Biodegradable Mg-1%Ca alloy inhibits the growth of cervical cancer.
Most Relevant Research
We explored how magnesium alloy, particularly a variant containing 1% calcium, impacts cervical cancer cells. Our investigation revealed that this alloy has promising antitumor properties which could pave the way for new treatments.

In our experiments, we tested the effects of the Mg-1%Ca alloy both in laboratory settings and in living organisms. This alloy was found to release magnesium ions and hydroxide ions more slowly than expected. We observed that it effectively inhibited the growth of cervical cancer cells, specifically SiHa and HeLa cell lines.

Additionally, the presence of the alloy induced apoptosis, or programmed cell death, in the cancer cells, disrupted their structural integrity, and hindered their ability to migrate and invade other tissues. Importantly, the Mg-1%Ca alloy was seen to influence key molecular pathways, specifically the MAPK/ERK signaling pathway, which plays a role in cancer cell proliferation.

With these results, it's evident that magnesium alloy could serve as a useful adjunct to current cervical cancer therapies, potentially helping to prevent both cancer growth and metastasis.

Embelin Elevates Endoplasmic Reticulum Calcium Levels and Blocks the Sterol Regulatory Element-Binding Protein 2 Mediated Proprotein Convertase Subtilisin/Kexin Type 9 Expression and Improves the Low-Density Lipoprotein Receptor Mediated Lipid Clearance on Hepatocytes.
Most Relevant Research
We examined the effects of embelin, a compound derived from the dried berries of Embelia ribes, on cholesterol levels by focusing on its relationship with calcium in liver cells. Our analysis showed that embelin treatment aids in regulating cholesterol metabolism by influencing key proteins associated with cholesterol clearance.

The study highlighted how embelin can elevate calcium levels within the endoplasmic reticulum (ER), which is essential for proper cellular function. By increasing calcium, we observed a decrease in the activity of a protein known as PCSK9, which typically hinders the liver's ability to remove low-density lipoprotein (LDL) cholesterol from circulation.

By regulating the levels of SREBP2, another protein linked to cholesterol control, embelin ultimately enhances the liver's capacity to clear LDL from the bloodstream. This mechanism reveals that calcium plays an important role, particularly in how embelin mediates cholesterol levels through its effects on proteins involved in cholesterol metabolism.

Overall, the findings suggest that embelin may offer a natural avenue for improving cholesterol management, particularly in the context of cardiovascular health.

Magnesium effectively lowers blood pressure
Magnesium and Potassium Supplementation for Systolic Blood Pressure Reduction in the General Normotensive Population: A Systematic Review and Subgroup Meta-Analysis for Optimal Dosage and Treatment Length.
Most Relevant Research
We explored how magnesium supplementation can affect systolic blood pressure (SBP) in the general population. Through careful analysis of placebo-controlled, randomized clinical trials, we focused on understanding the optimal dosages and treatment durations necessary to achieve significant reductions in SBP. Past findings revealed that magnesium could reduce SBP by an average of 2.79 mm Hg, and our goal was to dive deeper into these results.

Our meta-analysis showed promising outcomes. Specifically, we noticed that magnesium taken at lower doses, particularly ≤360 mg per day, led to a notable decrease in SBP of about 3.03 mm Hg, especially when the treatment duration exceeded three months. This suggests that for those looking to manage their blood pressure, longer-term use of magnesium at these dosages may be beneficial.

While we found encouraging evidence pointing to the effectiveness of magnesium in lowering SBP, we acknowledge the importance of further studies. These future investigations should focus on varied dosages and longer follow-up periods to strengthen our understanding and provide tailored recommendations for individuals seeking to utilize magnesium in their hypertension management strategies.

Magnesium's role in osteoporosis therapy
Mg-ZIF nanozyme regulates the switch between osteogenic and lipogenic differentiation in BMSCs via lipid metabolism.
Most Relevant Research
We explored the effects of a special material called magnesium-based zeolitic imidazolate frameworks, or Mg-ZIF, on osteoporosis. This study aimed to find a way to tackle osteoporosis by reducing reactive oxygen species (ROS)—harmful molecules that affect our bone health.

Our findings revealed that Mg-ZIF is effective at scavenging ROS, which helps boost the bone-forming ability of bone mesenchymal stem cells (BMSCs). By promoting osteogenic differentiation, Mg-ZIF supports the formation of new bone while simultaneously discouraging the development of fat cells from BMSCs, a process known as lipogenic differentiation.

In our in vivo experiments, we confirmed that administering Mg-ZIF could successfully lower ROS levels and mitigate the effects of osteoporosis. On a deeper level, the mechanism behind this involves Mg-ZIF enhancing BMSC differentiation into bone-forming cells by upregulating specific lipid metabolic pathways.

Overall, we believe that Mg-ZIF holds promise as a therapeutic approach for osteoporosis. By addressing the oxidative stress in the bone marrow environment, it opens a new door for potential treatments targeting this common bone disease.

We examined a combination product of carbonate antacids—specifically calcium carbonate and magnesium carbonate—with an extract from Opuntia ficus-indica, commonly known as prickly pear. This study looked at how this product could potentially protect esophageal cells from damage caused by both acidic and non-acidic reflux.

Through a series of laboratory tests, we aimed to understand the effectiveness of the product in two ways: neutralizing stomach acid and protecting esophageal cells. The carbonate ingredients showed promising results in neutralizing acidity, which is a common complaint for those suffering from heartburn. However, while calcium’s role in this combination is significant, it isn't isolated; the extract from prickly pear also plays a crucial role in lowering inflammation triggered by bile acids.

Ultimately, we found that the combination product provided dual benefits, helping cells withstand both acidic conditions and irritation from bile acids. Yet, it's essential to note that we could not determine the isolated impact of calcium on reflux, as it works in tandem with other active ingredients. This insight encourages further exploration into the specific effects of calcium in reflux management.

Thrombotic Complications Associated With Right Atrial Lines in Neonates and Infants Undergoing Cardiac Surgery. Is Calcium Chloride a Culprit?
Most Relevant Research
We explored the impact of different calcium infusions on clotting risks in neonates undergoing cardiac surgery. Our study involved analyzing data from 135 babies who received either calcium chloride or calcium gluconate during their treatment.

The findings highlighted a significant concern: when using calcium chloride, the incidence of thrombotic events was notably higher compared to those treated with calcium gluconate. Specifically, the odds of experiencing a blood clot were over three times greater in patients given calcium chloride.

With an overall thrombus occurrence of 9.9%, we observed that only 4.6% of the group receiving calcium gluconate developed such complications compared to 15% in the calcium chloride group. The evidence suggests that switching from calcium chloride to calcium gluconate could potentially reduce the risk of harmful blood clots in these vulnerable patients.

Calcium's complex impact on eczema
Correlation between dietary calcium intake and eczema in American adult population.
Most Relevant Research
We explored the connection between dietary calcium intake and the occurrence of eczema in adults using data from the National Health and Nutrition Examination Survey conducted in 2005-2006. Our aim was to see if there’s a relationship between how much calcium adults consume and the likelihood of developing eczema, a common skin condition.

In this observational study, we analyzed responses from 4,086 adults, of whom 266 reported having eczema. Our statistical analysis revealed an interesting pattern: we found that individuals in the third quartile of calcium intake had a significantly higher risk of eczema compared to those in the first quartile. Essentially, our results suggested that as dietary calcium intake increased, so did the prevalence of eczema—up to a certain point.

We identified an inverted U-shaped relationship between calcium intake and eczema prevalence. Specifically, an increase in calcium intake was associated with a higher occurrence of eczema until calcium levels reached a logarithmic value of 7.089. Thus, moderating calcium intake may help reduce the incidence of eczema.

These findings indicate that while calcium is essential for health, excessive consumption may not always be beneficial, particularly in relation to skin conditions like eczema. Further research is necessary to explore this relationship more deeply and determine the best levels of calcium intake for preventing eczema.

Eczema improved dramatically
Most Useful Review
The price-quality-dosage ratio is excellent: it lasts a long time and has a reasonable dosage, combining two vitamins in one. My husband and I have been taking them for three months. For optimal absorption, we take chlorophyll in the morning, multivitamins, omega, vitamin D3, and calcium with magnesium in the evening since magnesium and iron don't mix. After the autumn, when eczema appeared post-pregnancy and covered my body, the dermatologist noted that only vitamin D was deficient. Once I started taking the vitamins, the body atopy vanished, and my eczema became localized between my fingers. My general condition improved. I feel magnesium aids my emotional well-being, while calcium helps with my teeth and hair loss.

Magnesium implantation improves heart recovery
Magnesium implantation as a continuous hydrogen production generator for the treatment of myocardial infarction in rats.
Most Relevant Research
We explored the potential of magnesium implantation as a new approach to combat heart attacks, specifically myocardial infarction (MI). Our research centered on using magnesium slices implanted under the skin of rats to generate hydrogen gas continuously. This method could ensure a greater and longer-lasting concentration of hydrogen directly reaching the heart, which is crucial for its therapeutic effects.

Through our study, we measured how effectively the magnesium produced hydrogen and evaluated its safety. The results were promising; we observed that magnesium implantation not only improved cardiac function in rats suffering from MI, but also played a role in eliminating harmful free radicals from mitochondrial dysfunction. Furthermore, it helped reduce cell death in heart muscle cells, which is a common consequence of heart attacks.

Compared to traditional hydrogen inhalation, which has limitations in delivering sufficient doses over time, magnesium implantation proved to be a superior method. Overall, our findings pave the way for innovative treatments that could enhance recovery after heart attacks by harnessing the unique properties of magnesium for hydrogen production.

Magnesium shows promise in thyroid recovery
Proof of concept of the WOMED model of benign thyroid disease: Restitution of thyroid morphology after correction of physical and psychological stressors and magnesium supplementation.
Most Relevant Research
We set out to investigate how magnesium, along with selenium and coenzyme Q10, could influence hypothyroidism in patients with benign thyroid diseases. Our approach included a small group of eight patients—five with hyperthyroidism and three with hypothyroidism—who received additional treatment aimed at addressing both their thyroid condition and related physical and psychological stresses.

Over a period of 2 to 4 years, we observed some significant changes. Initially, we focused on correcting musculoskeletal issues, followed by addressing stress. As a result, we noted that thyroid morphology normalized in many cases, which was confirmed through ultrasound examinations. Interestingly, we also saw a reduction in thyroid antibody levels for most patients.

However, we must be transparent about our findings. While magnesium and the other supplements showed promise, there were two cases of chronic thyroiditis that did not respond positively to treatment, possibly due to long-standing fibrosis. This indicates that while magnesium may play a role in thyroid health, its effectiveness can vary significantly based on individual circumstances and the duration of the thyroid condition.

Magnesium's role in sleep apnea
Association between magnesium deficiency score and sleep quality in adults: A population-based cross-sectional study.
Most Relevant Research
We aimed to uncover the relationship between magnesium levels and sleep quality, particularly focusing on sleep apnea. Our study analyzed data from a large group of adults aged 20 and older, using a well-structured method to assess magnesium levels and the prevalence of sleep issues.

We found a notable connection between lower magnesium levels, measured as the magnesium depletion score (MDS), and the likelihood of experiencing sleep apnea. Specifically, individuals with higher MDS levels were significantly more likely to report sleep apnea, showing over three times the odds compared to those with adequate magnesium levels.

Interestingly, our research did not link magnesium deficiency to other sleep problems like insomnia or restless legs syndrome, suggesting a more complex relationship with sleep apnea alone. Additionally, we noticed that older adults with depressive symptoms showed a tendency toward excessive sleep rather than insufficient sleep.

While our findings highlight the association between magnesium deficiency and sleep apnea, they also point towards the potential of adequate magnesium intake in reducing this risk. This emphasizes the importance of maintaining proper magnesium levels for better sleep quality, especially in those at higher risk for sleep apnea.

Calcium Modulation for Stroke Recovery
Optogenetic calcium modulation in astrocytes enhances post-stroke recovery in chronic capsular infarct.
Most Relevant Research
We investigated the role of calcium in astrocytes to enhance recovery after a stroke. Focusing on a specific optogenetic tool called OptoSTIM1, we were able to selectively activate calcium channels in astrocytes. This approach allowed us to significantly elevate calcium levels in these supporting brain cells, particularly in the sensory-parietal cortex following a stroke.

Our findings revealed that this sustained calcium increase, lasting over 10 minutes, led to noticeable improvements in post-stroke recovery. By manipulating intracellular calcium levels in astrocytes, we observed a remarkable reduction in impairment caused by chronic stroke conditions.

This study highlights the potential of targeting astrocytic calcium signals as a promising strategy for enhancing stroke recovery, paving the way for new therapeutic approaches. Overall, our research suggests that calcium's role in astrocytes could be a game changer in the efforts to improve outcomes for stroke patients.

Hemoglobin increase linked to hypercalcemia
Effect of persistent hypercalcemia on hemoglobin levels after kidney transplantation.
Most Relevant Research
We investigated how persistent hypercalcemia—elevated calcium levels—affects hemoglobin levels in kidney transplant recipients (KTRs). Through a retrospective study including 385 patients, we analyzed the trajectories of hemoglobin in those with and without hypercalcemia.

Our findings revealed a surprising link: KTRs with persistent hypercalcemia exhibited higher hemoglobin levels over time—an increase of about 0.76 g/dL per year. This was especially pronounced in men, who showed an increase of 0.80 g/dL per year, compared to a more modest rise of 0.36 g/dL per year in women.

Additionally, our data indicated that these patients had a greater risk of developing post-transplant erythrocytosis, a condition characterized by an elevated red blood cell count. This relationship invites further consideration about the role of calcium levels in blood health, suggesting that rather than causing anemia as might be expected, hypercalcemia may drive erythrocytosis in this unique patient population.

Overall, this study emphasizes the complexity of calcium’s role in post-transplant health and highlights the importance of monitoring hemoglobin levels in KTRs, especially those with persistent hypercalcemia.

Magnesium's impact on heart health
The Role of Dietary Magnesium in Cardiovascular Disease.
Most Relevant Research
We examined the connection between dietary magnesium and cardiovascular disease, focusing on how magnesium intake or serum levels relate to heart health. Over the last couple of decades, numerous studies have shown that low magnesium levels are associated with several heart-related issues, including high blood pressure, heart attacks, and even heart failure.

Our insights reveal that even mild or moderate magnesium deficiencies can trigger physiological and metabolic changes that may heighten cardiovascular risks. When magnesium levels are insufficient, we see a rise in inflammation, oxidative stress, and issues with how fats are processed in the body, which can lead to serious heart problems.

Furthermore, we noted that many individuals often consume less magnesium than what is recommended, particularly those who do not regularly eat whole grains, legumes, or green vegetables. This widespread lack of magnesium is concerning, as it could be a significant factor influencing heart disease in the general population.

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.

Calcium's role in RA treatment
Hydrolysis of 2D Nanosheets Reverses Rheumatoid Arthritis Through Anti-Inflammation and Osteogenesis.
Most Relevant Research
We investigated how calcium, specifically in the form of two-dimensional layered calcium disilicide nanoparticles (CSNs), can play a role in treating rheumatoid arthritis (RA). Unlike typical RA treatments that primarily focus on reducing inflammation, we observed that CSNs have multifunctional properties that can address the inflammatory aspect while also promoting bone health and repair.

Through a process called hydrolysis, CSNs release several beneficial components, including hydrogen gas, calcium hydroxide, and silica. Each of these components contributes uniquely: hydrogen helps reduce harmful radicals and aids in adjusting surrounding immune cell behavior; calcium hydroxide counters the acidity that can worsen bone loss; and dissolved calcium works with phosphates to encourage bone formation.

We found that the application of CSNs had promising results in tests conducted on both mouse and rabbit models of arthritis. This approach not only targets inflammation but also fosters a healthier bone environment, showing potential as a strong therapeutic option for those living with RA. With high biocompatibility and prospects for clinical transformation, this research suggests a new direction in handling autoimmune disorders using calcium-based therapies.

We explored how severe calcium buildup in arteries may affect the success of heart stenting procedures, specifically focusing on identifying which calcified lesions might risk underexpansion of stents. In a study of 250 cases where optical coherence tomography (OCT) helped guide stenting, only those not treated with specific preparation methods were included.

The key findings showed that a significant portion—about 20%—of the lesions displayed stent underexpansion. We also discovered that certain features of the calcium, such as an angle over 270 degrees and a substantial thickness, were connected to reduced stent expansion.

Although the study emphasized calcium's role in predicting stent outcomes, we noted that it didn’t isolate how calcium management impacts heart disease directly. Thus, while the revised calcium scoring system can be useful in assessing stent expansion risk, the benefits of calcium treatment on heart disease remain less clear.

Magnesium boosts colonic activity
Effects of oral magnesium sulphate on colonic motility in patients with the irritable bowel syndrome.
Most Relevant Research
We set out to understand how magnesium sulphate influences the symptoms of irritable bowel syndrome (IBS). In a study involving 20 IBS patients, magnesium sulphate was administered orally, resulting in a quick boost in colonic motor activity. Most participants experienced this increase within just two to six minutes.

Specifically, the percentage of colonic activity rose from 16.2% to 23.7%, signaling a notable change. Those who often felt abdominal pain after eating showed even more pronounced reactions, with their activity jumping from 16.1% to 29.8%. However, it’s important to note that three of these patients still experienced their usual pain after taking magnesium, suggesting that while magnesium can enhance motility, it doesn’t eliminate the pain for everyone.

Ultimately, these findings lend support to the idea that some cases of abdominal pain related to food may stem from heightened intestinal responses to cholecystokinin, a hormone released by the intestine. So while magnesium shows promise for intriguing changes in colonic movement in IBS patients, its effectiveness in alleviating pain remains mixed.

Most Relevant Research
We explored how changing the frequency of magnesium oxide (MgO) doses influences its effectiveness in relieving constipation. In this study, we looked at 11 patients who had been regularly using MgO to manage their bowel movements and decided to reduce their daily dose frequency over two weeks.

Initially, patients were taking magnesium three times a day, but we reduced this to either two or one dose per day while keeping the total amount the same. We found that the average number of bowel movements dropped from 7.6 to 6.6 in this period. However, this change wasn't statistically significant, indicating that it may not be clinically meaningful.

Additionally, we measured stool consistency using the Bristol Stool Form Scale and noted no significant difference before and after the dosage adjustment. Our findings suggest that reducing the number of doses does not impact the laxative effect of magnesium oxide. This implies that patients can comfortably manage their magnesium intake without sacrificing effectiveness.

We aimed to investigate the connection between calcium levels and depression, specifically comparing unipolar and bipolar disorders. In the course of our pilot study, we enrolled 36 patients admitted to the University of Insubria Psychiatric Unit, who completed various psychological assessments to gauge their mental health.

Our findings revealed a noteworthy association between calcium levels and bipolar depression. We observed significant correlations not only between calcium and depressive symptoms, but also with inflammation markers like CRP (C-reactive protein). This indicates a possible relationship where lower calcium levels may relate to more severe symptoms in individuals with bipolar disorder.

While these associations are intriguing, it's important to note that we did not isolate the effects of calcium treatment itself on depressive symptoms. Therefore, while our results push the conversation forward regarding the role of calcium in mental health, they do not establish that calcium treatment is definitively beneficial for those struggling with depression.

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.

Magnesium reduces kidney stone risk
Effect of magnesium oxide or citrate supplements on metabolic risk factors in kidney stone formers with idiopathic hyperoxaluria: a randomized clinical trial.
Most Relevant Research
We conducted a randomized, double-blind, placebo-controlled clinical trial to explore how magnesium treatments influence kidney stones, specifically for those with high levels of oxalate in their urine. Our study involved 90 participants with a history of calcium kidney stones, all of whom were experiencing idiopathic hyperoxaluria. They were divided into three groups receiving either magnesium oxide (MgO), magnesium citrate (MgCit), or a placebo for eight weeks, while their diets were monitored to keep nutritional intake consistent.

After the treatment period, we observed promising results. Both MgO and MgCit effectively reduced the excretion of oxalate in urine, which is a key factor in kidney stone formation. The Group taking magnesium citrate showed even more significant reductions in both oxalate levels and the calcium oxalate supersaturation index, which measures the concentration of stone-forming minerals in urine. This was notably true for participants with normal magnesium levels.

Overall, we found that magnesium supplements might play a beneficial role in decreasing critical risk factors for kidney stones, especially for those using magnesium citrate. It's encouraging to see that this may offer a practical option for those struggling with recurrent stones due to high oxalate excretion.

Excellent 2:1 calcium to magnesium ratio. These minerals complement each other for better absorption, with magnesium preventing kidney stones by aiding calcium dissolution in the blood.
