We examined how magnesium supplements might influence heart failure and serious heart-related issues in diabetic patients.
In a study involving over 94,000 veterans, we found that those taking magnesium supplements experienced a lower risk of heart failure compared to nonusers. Specifically, 8.0% of supplement users developed heart failure, versus 9.7% of nonusers.
Furthermore, magnesium intake was linked to a reduced chance of major adverse cardiac events. However, it’s important to note that these findings need further investigation through randomized controlled trials.

We explored how magnesium supplementation might influence mortality rates in patients with heart failure and preserved ejection fraction (HFpEF). The study involved nearly 2,000 patients, with careful matching to ensure a fair comparison between those receiving magnesium and those who weren’t.
Interestingly, we found that magnesium intake was linked to a significant reduction in 28-day mortality rates. This effect was most notable in older adults, women, and patients with high blood pressure. Despite these positive findings, magnesium treatment did lead to longer hospital and ICU stays.
Overall, magnesium shows promise as a supportive treatment for HFpEF, but further investigation is necessary to better understand its benefits and implications.

Magnesium levels and heart disease mortality
We examined the link between serum magnesium levels and the risk of death from heart failure, coronary heart disease, and stroke in patients with chronic kidney disease who don’t require dialysis. Over a decade, we followed 1,271 patients, noting that those with higher magnesium levels experienced significantly lower mortality rates from these conditions.
This suggests that maintaining adequate magnesium levels may help improve health outcomes for individuals with advanced kidney issues and an increased risk of cardiovascular problems.

Magnesium for heart

My mum has a heart issue. They found a significant deficiency in magnesium during her trace element analysis. Following her doctor's advice, she took this specific magnesium form, which is beneficial as excess magnesium is naturally expelled by the body. Mum regularly consumes this magnesium and really appreciates its effects.

Magnesium intake impacts heart disease risk
We explored the link between magnesium intake and heart disease risk in young adults, using a comprehensive study of U.S. adults aged 20 to 34. This cross-sectional research analyzed data from the National Health and Nutrition Examination Survey, examining dietary habits and various cardiovascular factors.
Our findings suggest that higher magnesium intake is associated with a lower risk of future cardiovascular issues and non-HDL cholesterol problems. This suggests that including magnesium-rich foods in our diets could promote heart health early in life.

We analyzed several clinical trials to examine how magnesium and potassium affect systolic blood pressure (SBP) in healthy individuals. Our findings showed that magnesium significantly reduced SBP, especially at lower doses (up to 360 mg/day) and longer treatment periods of over three months. Potassium also played a role but was effective at higher doses and shorter durations.
However, both supplements showed promise in lowering SBP but did not seem to drastically change heart disease risk directly. Further studies will help confirm our results and refine dosage recommendations for better health outcomes.

We explored how the serum calcium-magnesium ratio impacts outcomes in patients with acute coronary syndrome (ACS) by analyzing data from 1,775 individuals who underwent coronary procedures over five years.
By categorizing patients based on their calcium-magnesium levels at admission, we discovered that a higher calcium-to-magnesium ratio correlated with worse outcomes.
Our findings suggest that monitoring this ratio could help predict the prognosis for those dealing with ACS, emphasizing the importance of maintaining a balanced mineral intake for heart health.

Vital magnesium effects
42 people found this helpful
Best of all. I noticed results by day three. Magnesium is essential for sleep quality, protein synthesis, and the central nervous system. It's involved in 80% of biochemical reactions, and a deficiency can increase sensitivity to stressors like anxiety and insomnia. For older adults, maintaining magnesium levels is crucial, as low amounts increase risks of strokes, heart attacks, and thrombosis. This magnesium is highly effective.

Consult professionals
Magnesium threonate effectively crosses the blood-brain barrier, supporting brain health by improving memory, concentration, reducing stress and anxiety, and promoting sleep. It also contributes to strong bones and reduces muscle spasms while regulating heartbeat to lower heart disease risk. However, consult your doctor before starting any supplements, including magnesium threonate, to determine dosage and monitor for interactions.

Cognitive clarity

The neurologist prescribed this magnesium after my vascular disease. I struggled with confusion and memory issues, which heavily impacted my life. However, after starting the supplement, my mental clarity improved within days, and my speech returned to what it was before the illness. This magnesium works significantly better than regular types!

Children's health improvement
Our whole family takes magnesium. The capsules are large yet easy to swallow; I often open them for my children. My daughter's leg pains vanished with magnesium use. The taste is neutral, and my child takes it willingly. I've noticed she's calmer, falls asleep faster, manages schoolwork better, and has improved memory. My sleep has also enhanced, and I'm grateful to Iherb for quality packaging and timely delivery.

Supports brain function
1 people found this helpful
The only magnesium type that crosses the blood-brain barrier effectively increases magnesium levels in the brain. Adequate brain magnesium aids memory and learning, protects against age-related changes, and supports mental functions. It's also crucial for the cardiovascular system, affecting heart disease positively by regulating heart cell function, lowering blood pressure, and preventing rhythm disturbances. I take three capsules daily.

We investigated the effect of magnesium and calcium on blood sugar levels in 11,934 patients with coronary artery disease. Our findings indicated that higher serum magnesium levels and a favorable magnesium to calcium ratio were associated with lower abnormal HbA1c levels, which reflect better blood sugar management. In contrast, calcium showed no significant association with HbA1c levels. Importantly, we found no evidence that inflammation played a role in this relationship. Overall, magnesium might be beneficial for maintaining healthy blood sugar levels in those with heart disease.

We examined how changes in serum magnesium levels affect in-hospital mortality for patients experiencing acute myocardial infarction (AMI). This study analyzed data from 2,716 AMI patients in the MIMIC database.
Surprisingly, we found that higher magnesium levels upon ICU admission and within the first 48 hours were linked to increased mortality rates. Regardless of age, gender, or severity scores, this trend persisted, suggesting that monitoring magnesium levels closely could be crucial for improving patient outcomes in the hospital setting.
