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.
Strong relevance to CAD management
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 shows promise for angina
Effect of magnesium sulphate in patients with unstable angina. A double blind, randomized, placebo-controlled study.
Results indicate potential clinical value.
We aimed to understand how a 24-hour infusion of magnesium sulphate affects patients with unstable angina. In a double-blind, placebo-controlled study, 62 patients were monitored for signs of myocardial ischaemia after receiving either magnesium or a placebo.

While both groups showed some ECG changes, the magnesium group had fewer overall ischaemic episodes and lower levels of heart enzyme release. Additionally, magnesium seemed to reduce stress hormone levels. Our findings suggest that magnesium can be a valuable treatment option for unstable angina, but more research is needed to confirm its effectiveness.

Magnesium supplementation aids chest pain
The prevalence of hypomagnesaemia in pediatric patients with mitral valve prolapse syndrome and the effect of mg therapy.
Direct focus on magnesium treatment
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.

Miracle supplement
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!

Eases chest pain
Good product at a great price! It alleviates muscle tension and helps with restless leg syndrome, while also reducing my chest pain associated with ME/CFS. I’ve recently discovered that iHerb offers a chelated magnesium, which may be better for my body, so I plan to purchase that in the future. Thank you for the excellent service!

Not effective for chest pain
This magnesium formulation contains various forms, yet only magnesium citrate is well absorbed. The others might not provide benefits and could be harmful. If you're seeking a budget option, I recommend pure magnesium citrate, especially if you lack gastrointestinal issues. Otherwise, this may not effectively treat chest pain.

Magnesium's unclear role in chest pain
An adolescent with tingling and numbness of hand: gitelman syndrome.
Moderate relevance; combined therapy analyzed
We examined the role of magnesium in treating chest pain, particularly in a case involving a young female with Gitelman syndrome. This patient experienced recurrent chest pain alongside symptoms like tingling and numbness, prompting a thorough investigation into her condition.

Our exploration revealed that magnesium was indeed part of the treatment plan, but it was combined with potassium and amiloride. This combination makes it challenging to determine how much magnesium alone contributed to alleviating the patient's chest pain.

While magnesium is commonly recognized for its various health benefits, in this specific case, we did not see a clear, isolated benefit from it. Instead, the overall treatment approach seemed to require multiple interventions to achieve improvements in symptoms and biochemical markers.

Potassium magnesium aspartate improves chest pain
[Clinical investigation of the protective effects of potassium magnesium aspartate against arrhythmia and its possible anti-oxidative mechanism].
Moderate relevance regarding isolated effects
We explored how potassium magnesium aspartate could offer protective benefits against chest pain linked to coronary artery disease. In a study involving 98 patients with angina and arrhythmia, participants were divided into two groups. One group received the routine treatment for heart disease along with potassium magnesium aspartate, while the other only received the standard therapy.

After a week of treatment, we examined various markers of oxidative stress and monitored cardiac rhythms. The results were promising: potassium magnesium aspartate significantly improved oxidative stress levels and reduced lipid oxidative damage in patients. Notably, there was a marked decrease in the frequency of premature heartbeats in those receiving potassium magnesium aspartate compared to the control group.

It appears that by enhancing oxidative stress status, potassium magnesium aspartate may also contribute to alleviating symptoms associated with arrhythmia, including chest pain. This suggests that oxidative stress could play a critical role in the development of arrhythmias, and addressing it might help treat related symptoms effectively.

Magnesium benefits CAD patients
Oral magnesium therapy, exercise heart rate, exercise tolerance, and myocardial function in coronary artery disease patients.
Significant magnesium treatment effects
In a controlled study involving 53 male patients with stable coronary artery disease (CAD), we investigated the impact of oral magnesium supplementation on exercise-related heart rate and chest pain. Some participants received 15 mmol of magnesium twice daily, while others were given a placebo for six months.

Our findings revealed that those who took magnesium experienced improved exercise tolerance and better left ventricular function during both rest and exercise. Importantly, magnesium appeared to help reduce exercise-induced chest pain, which is often a concern for those with CAD.

By observing changes in maximal oxygen uptake and heart performance curves, we gained valuable insights into the potential benefits of magnesium therapy. The study highlights a promising option for those dealing with the challenges of CAD, particularly in managing discomfort during physical activity.

Chest pain issues
After two weeks of capsules, I experienced painful stomach cramps, leading me to stop taking them. I’ve previously taken other magnesium supplements without this reaction, as I have chronic gastritis and didn’t expect such discomfort.

Severe abdominal pain
After a month of use, I found that my stomach often reacted with pain after taking it. Initially, I thought it was a chance occurrence, but the pain continued, and I experienced strong spasms after taking it. I associate these issues with using this magnesium supplement.
