Magnesium Aspartate and Blood Pressure Benefits
Magnesium aspartate supplementation has shown potential to lower blood pressure in women with mild to moderate hypertension. In a controlled trial, women taking magnesium aspartate-HCl experienced a greater reduction in diastolic blood pressure compared to those taking a placebo, suggesting a beneficial effect for blood pressure management in this group. The supplement was well-tolerated and did not increase the risk of diarrhea compared to placebo . However, another study found no significant effect of magnesium aspartate on blood pressure in patients with mild to moderate hypertension, indicating that results may vary depending on the population studied .
Magnesium Aspartate and Insulin Resistance
Oral magnesium aspartate supplementation has been shown to improve insulin sensitivity in overweight, non-diabetic individuals with insulin resistance. Participants who took magnesium aspartate-hydrochloride had better fasting plasma glucose levels and improved insulin sensitivity indices compared to those on placebo, even when their baseline magnesium levels were normal. This suggests that magnesium aspartate may help prevent insulin resistance and reduce the risk of developing type 2 diabetes . In diabetic patients on hemodialysis, combining magnesium aspartate with L-carnitine improved insulin resistance and reduced markers of chronic inflammation, which may help lower cardiovascular risk .
Magnesium Aspartate for Cardiovascular Health
Magnesium aspartate, especially when combined with potassium or L-carnitine, has been found effective in the management of various cardiovascular conditions. Clinical studies support its use in the complex therapy of arrhythmias, coronary heart disease, chronic heart failure, and arterial hypertension . In diabetic hemodialysis patients, the combination of magnesium aspartate and L-carnitine helped prevent the progression of atherosclerosis and heart valve disease, reduced inflammation, and protected the endothelium, which may contribute to lower cardiovascular risk 710.
Magnesium Aspartate and Sleep or Athletic Performance
Studies on zinc magnesium aspartate (ZMA) supplementation in healthy males found no significant benefits for sleep quality, cognitive performance, or submaximal weightlifting performance, even after sleep deprivation. In some cases, ZMA supplementation slightly reduced total sleep time compared to placebo or no supplementation 25.
Magnesium Aspartate in Animal Health and Food Quality
In animal studies, magnesium aspartate supplementation improved stress resistance and meat quality in pigs, leading to higher muscle pH, less drip loss, and a lower incidence of poor-quality meat. In heat-stressed laying hens, magnesium aspartate reduced body weight loss, suggesting an antistress effect that could help maintain performance under challenging conditions 69.
Conclusion
Magnesium aspartate supplementation may offer benefits for blood pressure control, insulin sensitivity, and cardiovascular health, particularly in specific populations such as those with hypertension, insulin resistance, or chronic kidney disease. Its effects on sleep and athletic performance in healthy individuals appear minimal. In animal studies, magnesium aspartate supports stress resistance and improves product quality. Overall, magnesium aspartate is well-tolerated and may be a useful supplement for targeted health concerns.
