Magnesium shows promise for RA treatment
Magnesium Supplementation Modifies Arthritis Synovial and Splenic Transcriptomic Signatures Including Ferroptosis and Cell Senescence Biological Pathways.
Relevant for autoimmune treatment strategies
We analyzed how magnesium supplementation affects the biology of rheumatoid arthritis (RA) in mice. By feeding one group a diet rich in magnesium and another a standard diet over 15 days, we examined changes in their tissue responses.

Our findings revealed that increased magnesium intake may alter gene expression linked to oxidative stress and cellular aging, processes that are significant in RA development. This suggests that magnesium could be beneficial for managing RA and potentially other autoimmune disorders by reducing disease severity and joint damage.

Magnesium may reduce lupus severity
Revised version with tracked changes oral Magnesium reduces levels of pathogenic autoantibodies and skin disease in murine lupus.
Relevance score reflects promising findings.
We investigated how magnesium (Mg) affects the severity of autoimmune lupus in mice. By feeding MRL/lpr female mice a standard or high magnesium diet for nine weeks, we measured impacts on skin lesions and pathogenic autoantibodies.

The results were encouraging: mice on the high magnesium diet showed significant reductions in skin issues and harmful anti-dsDNA antibodies. Plus, their immune systems displayed more regulatory T cells. However, there were no notable differences in other measured health indicators.

Overall, magnesium supplementation may be a cost-effective and safe complementary treatment for lupus.

Zinc supplementation benefits MS models
Dietary zinc status is associated with ZnT3 (SLC30A3), IL-6 gene expressions and spinal cord tissue damage in spinal cord tissue in a cuprizone-induced rat Multiple Sclerosis model.
Study highlights zinc's impact
We explored how dietary zinc levels influence spinal cord damage and gene expressions associated with Multiple Sclerosis (MS) using a cuprizone-induced rat model. The study included 46 adult male Wistar rats divided into five groups, with some receiving zinc supplementation while others followed a zinc-deficient diet.

After eight weeks of treatment, we found that the rats with MS symptoms showed elevated markers of tissue damage and inflammation, particularly in the groups that lacked zinc. Notably, those receiving zinc supplementation exhibited significantly reduced levels of harmful substances, bringing them back closer to control levels.

Our findings highlight zinc's protective effects in a model of MS, suggesting that incorporating zinc into treatment plans could help alleviate some symptoms associated with this autoimmune disorder. This is promising for future treatment strategies for those affected by MS.

Improved sleep quality
I appreciate being able to take magnesium and calcium together, particularly with higher magnesium content. Originally, I took it to treat my atopic dermatitis, which is now completely healed, so I now only take it with other vitamins when particularly fatigued. The refreshing effect is evident the next morning. I am careful not to over-supplement to avoid straining my liver.

Better sleep
I bought this for my husband due to his hard work and sleep difficulties. After three months of use, the results are evident; he sleeps soundly and has become much less anxious.

Effective against constipation
I generally take one tablet in the morning and evening instead of the recommended three for effective relief from constipation! It has become a vital addition to my daily routine due to mineral deficiencies. Noticing the included 1000 IU of vitamin D, I adjust my intake accordingly on sunny days. The large tablets became a mere habit for me. I am reordering as this product ensures I avoid constipation, and during a week without it, I regrettably experienced discomfort.

Calcium's role in RA treatment
Hydrolysis of 2D Nanosheets Reverses Rheumatoid Arthritis Through Anti-Inflammation and Osteogenesis.
Focus on calcium's therapeutic potential
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.

Magnesium-based therapy for RA
Anti-Acidification and Immune Regulation by Nano-Ceria-Loaded Mg-Al Layered Double Hydroxide for Rheumatoid Arthritis Therapy.
New therapeutic approach for RA
We explored the potential of a new magnesium-aluminum layered double hydroxide combined with nano-ceria in treating rheumatoid arthritis (RA). This innovative therapy targets the unhealthy immune environment and the harmful buildup of hydrogen ions associated with RA. By neutralizing excess acidity, we observed improved immune responses, encouraging the body to heal damaged bones. This approach showed promising results in mice models, indicating it may be a viable future treatment for managing RA effectively.

Magnesium aids arthritis through immunity
Magnesium increases numbers of Foxp3+ Treg cells and reduces arthritis severity and joint damage in an IL-10-dependent manner mediated by the intestinal microbiome.
High relevance for autoimmune therapies
We explored the effects of a high magnesium diet on rheumatoid arthritis using two mouse models. Our findings suggest that magnesium can significantly reduce arthritis severity and joint damage, while also promoting immune cell types that help combat inflammation.

Interestingly, these benefits seem to hinge on an immune mediator called IL-10 and changes in the gut microbiome, such as increased beneficial bacteria. While our results are promising, it is important to recognize that the protective effects depend on sufficient levels of IL-10, indicating that the relationship between magnesium and immune regulation is quite intricate.

Increased calcium
I’ve been taking this calcium supplement for three months now after seeing a recommendation from a blogger. It has worked wonders for me. I was deficient in calcium, but after recent tests, I was thrilled to find my levels have improved. The inclusion of magnesium, zinc, and D3 has also bolstered my immunity. I wholeheartedly recommend ordering this product!

Reduced irritability
The results were apparent within a week. I ordered it for my husband who was quite irritable. Following the doctor's advice, we combined Magny with calcium for better absorption, and we found it to be effective. After a week, he was noticeably calmer and his sleep improved. We will definitely order more!
