Nutrient Detail Information
Nutrient Summary	Magnesium helps regulate muscle and nerve function, blood sugar levels, and blood pressure. It plays role in making protein, bone, and DNA.
Nutrient Function	• Regulate blood sugar level: magnesium helps the body break down sugars • Regulate blood pressure (decrease blood pressure by a small amount) • Maintain intracellular levels of potassium and calcium • Bone health: increase bone mineral density which reduces the risk of bone fractures and osteoporosis • Enable muscle contraction • Nervous system function, such as sending messages • Normalize heart rhythm • Protein synthesis • Is required for the synthesis of DNA, RNA • Is required for energy production, oxidative phosphorylation, and glycolysis Magnesium is maintained primarily by the kidneys, where it is filtered and reabsorbed and excessive magnesium is efficiently excreted in urine. Magnesium exists in bones and soft tissues.
Food Sources Top Food Sources	• Green leafy vegetables, such as spinach • Whole grains • Nuts and pumpkin seeds • Potatoes • Dairy products, such as cheese • Fruits, such as raisins and bananas • Beans and peas, such as black beans and soybeans • Tap, mineral, and bottled waters may also contain magnesium Notes: 1) Refined and processed foods contain less magnesium. 2) High levels of dietary fiber from fruits, vegetables, and grains decrease magnesium absorption or retention, or both. 3) Phosphorus may decrease magnesium absorption. 4) High protein intakes may improve magnesium absorption and retention.
Deficiency Health Effects	The potential effects of magnesium deficiency include: • Loss of appetite, nausea, vomiting, fatigue, and weakness. • Muscle cramps, latent tetany, spontaneous carpopedal spasm, and seizures. • Symptomatic hypocalcemia (when magnesium deficiency becomes moderate to severe) People who are more likely than others to have magnesium deficiency: • With gastrointestinal diseases • With type 2 diabetes • Long-term alcoholism • Older people
Effects if Above Upper Limit	Magnesium intake from nature foods doesn't show adverse effects for almost all people. However, adverse effects were observed from excessive intake of nonfood sources, such as various magnesium salts. The adverse effects include: • Diarrhea (primary symptom) • Nausea • Abdominal cramps Note: per Dietary Reference Intakes booklet, the Upper Limit values listed in the table represent intake from pharmacological agents only and do not include intake from food and water.
