A Harvard study revealed that increased intakes of magnesium-rich foods reduces sudden heart failure risk for women. The risk reduction when taking the mineral approached up to 37% compared to the lowest average intakes. Earlier research in the USA learned that a large portion of the adults do not meet the recommended daily intake for magnesium, 320mg/day for women and 420mg/day for men. Potential cardiovascular benefits of the mineral were highlighted in a review in the Journal of the American Academy of Nurse Practitioners (2009, Vol. 21, pp. 651-657), which found that increased intakes of magnesium may reduce the risk of coronary heart disease (CHD) in men, but the evidence is lacking for women. Reviewers Tavia Mathers and Renea Beckstrand from Brigham Young University concluded that, with the mineral being implicated in more than 300 biochemical reactions in the body, and toxicity issues being rare, “oral magnesium supplementation is recommended”.
