Magnesium Deficiency Affects Many Adults

Magnesium is required for more than 300 enzymatic reactions, according to the National Institutes of Health, as cited in an article on Mercola.com. [1] An estimated 45% of American adults do not meet the recommended dietary allowance (RDA) for magnesium from their diet, a 2011 report stated. [2] The RDA for magnesium is 310 to 320 milligrams (mg) per day for women and 400 to 420 mg per day for men, depending on age, according to a NaturalNews.com report. [3] Chronic stress, pregnancy and intense exercise may increase magnesium requirements, officials said. The mineral is necessary for the healthy functioning of most cells, especially the heart, kidneys and muscles, according to Mercola.com. [4] Green vegetables such as spinach provide magnesium because the center of the chlorophyll molecule contains magnesium, the "Alternative Medicine Sourcebook" noted. [5]

Top Food Sources of Magnesium

Pumpkin seeds and spinach are among the most concentrated food sources of magnesium, according to a report on NaturalNews.com. [6] One ounce of almonds contains 76.5 mg of magnesium, the report stated. [6] Green vegetables such as spinach provide magnesium, and nuts, seeds, and some whole grains are also good sources, the Alternative Medicine Sourcebook noted. [5] Individuals who consume nuts, seeds and green vegetables likely obtain ample magnesium, according to Earl Mindell's "Vitamin Bible." [7] Additional foods that contribute magnesium to the diet include black beans, edamame, dark chocolate, avocado, tofu, yogurt and bananas, according to dietary sources. One avocado, for example, provides magnesium along with fiber and monounsaturated fats. Tofu, a versatile plant-based protein, varies in magnesium content depending on processing. Yogurt offers magnesium along with protein and probiotics. Dark chocolate with 70% cacao or higher contains cocoa polyphenols and is a source of magnesium, according to nutrition experts. Both dark chocolate and avocados are examples of whole foods that provide the mineral along with other beneficial nutrients such as antioxidants and healthy fats. [8]

Supplement Considerations

Supplements may be useful when dietary intake is consistently low or needs are elevated, according to health experts. Different forms serve different goals: magnesium glycinate is often chosen for relaxation and is gentler on digestion, officials said. [9] According to the "Health Ranger Report," magnesium glycinate can support heart and muscles. [9] The ratio of calcium to magnesium is important, as an excess of calcium can lead to magnesium deficiency, according to Ann Louise Gittleman in Super Nutrition for Menopause. [10] Magnesium also works best with vitamin A, calcium, and phosphorus, according to Earl Mindell's Vitamin Bible. [11] A supplement providing 230 mg of combined magnesium glycinate and malate is noted as a night-time option for relaxation and muscle health, according to a review of dietary supplements. [8] Consumers are advised to consult a health care provider before starting any supplement regimen, especially during pregnancy or while taking medications.

Takeaway

Magnesium plays a role in energy production, muscle function, sleep, and cardiovascular health, according to the National Institutes of Health. [1] Many adults fall short on intake, but foods such as leafy greens, legumes, nuts, seeds, and dark chocolate can help meet daily needs. [2] Increasing dietary magnesium through whole foods also provides additional nutrients like fiber and healthy fats, the report noted. [4] Consumers are advised to consult a health care provider before starting any supplement regimen, especially during pregnancy or while taking medications. The best approach to maintaining adequate magnesium levels is to incorporate a variety of whole foods into the diet, including those rich in magnesium, such as pumpkin seeds, spinach, almonds, black beans, and avocado.
