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 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.

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.

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.

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.

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.

This magnesium offers excellent value for money. I take one capsule at night, and it significantly improves my sleep while reducing nervous tension. The capsules are large but easy to swallow.

Migraine relief
Most Useful Review
I regularly purchase magnesium supplements, as many people are deficient, especially those under stress or with demanding lifestyles. After struggling with chronic migraines and using harsh medications that burdened my liver, I took 400 mg of magnesium with Vit D before bed. My migraines vanished, and my blood pressure normalised. A follow-up blood test revealed my magnesium levels were at the lower limit of normal. I highly recommend this product.

Magnesium improves chest pain outcomes
Effects of oral magnesium therapy on exercise tolerance, exercise-induced chest pain, and quality of life in patients with coronary artery disease.
Most Relevant Research
We examined how oral magnesium might enhance quality of life and reduce exercise-induced chest pain for those with coronary artery disease (CAD). In an impressive multicenter trial, 187 patients were randomly assigned to receive either magnesium supplements or a placebo for six months.

Our findings show that magnesium therapy improved exercise duration and decreased chest pain during exertion. Participants receiving magnesium reported both enhanced exercise tolerance and better quality of life compared to those on a placebo. This suggests that magnesium supplementation could play an important role in managing CAD symptoms.

Magnesium supplementation is essential! It supports the nervous, cardiovascular, and cartilage systems. For those with joint pain, it's a miracle supplement. My aunt suffers from osteoarthritis, but since she began taking Magnesium daily, her pain has disappeared. I highly recommend it!

Magnesium alleviates primary dysmenorrhea
Effectiveness of magnesium pidolate in the prophylactic treatment of primary dysmenorrhea.
Most Relevant Research
We evaluated how magnesium pidolate impacts primary dysmenorrhea in 30 young women. Over six menstrual cycles, we tracked their pain levels using a visual scale. Initially, no treatment was given, and subsequently, magnesium was administered just before menstruation.

The first day of menstrual pain showed a notable decrease with magnesium treatment, especially from the first to the sixth cycle. While there were some improvements on days two and three, those weren't statistically significant. Importantly, no side effects were reported, suggesting magnesium can be a reliable option for managing menstrual pain.

Low back pain has disappeared! My daughter suggested adding magnesium to balance the calcium I was taking, and I am now completely without low back pain. Thank you, iHerb!
