In 2009, the World Health Organization reported that 75% of Americans were magnesium deficient. A recently published meta-analysis of forty separate studies from nine countries regarding the effects of magnesium on human health involved over one million participants over a period of four to thirty years and found some interesting results. Here’s what they found: Many people have low serum (blood) magnesium levels (2.5-15% of subjects in included studies). Increasing daily magnesium by 100mg a day didn’t affect the incidence of cardiovascular disease or coronary heart disease. Increasing daily magnesium intake by 100mg a day significantly reduced the risk of stroke, heart failure, type 2 diabetes, and all-cause mortality. Moreover: “…many adults fail to meet the recommended daily intake of magnesium, despite the fact that epidemiology studies indicate that low levels of serum magnesium can increase the risk of a wide range of diseases, including chronic obstructive pulmonary disease, metabolic syndrome, type 2 diabetes (T2D), Alzheimer’s disease, and cardiovascular disease (CVD)…However, no clear association was found between magnesium intake and the risk of coronary heart disease or total cardiovascular disease, which may have been due – at least in part – to the relatively limited number of studies included in our analysis.” (5) « Previous Next »
