Every organ in the body requires magnesium. Magnesium is especially important for the kidneys, heart and muscles. Magnesium is sometimes given intravenously to reduce the chance of an irregular heart beat. Calcium channel blockers often used to regulate blood pressure might interact with magnesium to cause side effects such as dizziness, nausea and fluid retention in pregnant women. A combination of calcium and magnesium may also help with fibromyalgia, irregular heart beat and heart failure. Consult a primary care physician before adding magnesium and calcium supplements to the diet as precise ratios are important.
Calcium
Calcium is important for growing bones and also helps individuals control blood pressure and maintain heart beat. Individuals who do not consume enough calcium are at risk of osteoporosis later in life. Calcium dosage depends on age and gender. Typically, women who are breast feeding and lactating do not need to take additional calcium supplements other than the daily recommendation.
Calcium Dosage
Female and male adolescents are recommended to consume higher amounts of calcium. The Office of Dietary Supplements, or ODS, recommends children aged 9 to 18 take 1,300 mg of calcium daily; people 19 to 50 need 1,000 mg daily, while people 51 and older require 1,200 mg each day.
Magnesium
Individuals obtain enough magnesium in their diet by eating a variety of fruits and vegetables. Individuals who do not get enough magnesium in their diet could consider taking supplements. Magnesium may have various side effects including a calcium deficiency. Women who are pregnant may require additional magnesium than the daily suggested amount.
Magnesium Dosage
ODS suggested males between 14 to 18 years old consume 410 mg of magnesium daily. Females aged 14 to 18 need 360 mg daily, while older men between 19 and 30 years need 400 mg daily; women the same age need 310 mg. Men and women over 30 require 420 daily mg and 320 mg, respectively. Parents should consult a pediatrician before adding calcium and magnesium to their infant's or child's diet.
Combination
Supplements with calcium and magnesium may help people with fibromyalgia, irregular heart beat and heart failure. Magnesium and calcium need to work together at very precise ratios to ensure your heart functions properly. It is unclear whether this is an effective form of treatment. Magnesium also competes with calcium for absorption into the body.
