Symptoms of magnesium deficiency include loss of appetite, nausea, vomiting, fatigue, and weakness. Extreme magnesium deficiency can cause numbness, tingling, muscle cramps, seizures, personality changes, and an abnormal heart rhythm.
Magnesium plays many crucial roles in the body, such as supporting muscle and nerve function and energy production. Low magnesium levels usually don't cause symptoms. However, chronically low levels can increase the risk of high blood pressure, heart disease, type 2 diabetes and osteoporosis.
Even though magnesium is found in whole grains, nuts and seeds, bananas, dark leafy greens and even dark chocolate, it is widely deficient in many people.
RDA: The Recommended Dietary Allowance (RDA) for adults 19-51+ years is 400-420 mg daily for men and 310-320 mg for women. Pregnancy requires about 350-360 mg daily and lactation, 310-320 mg. UL: The Tolerable Upper Intake Level is the maximum daily intake unlikely to cause harmful effects on health.
Every organ in the body, especially the heart, muscles, and kidneys, needs the mineral magnesium. It also contributes to the makeup of teeth and bones.
People with diabetes, intestinal disease, heart disease or kidney disease should not take magnesium before speaking with their health care provider. Overdose. Signs of a magnesium overdose can include nausea, diarrhea, low blood pressure, muscle weakness, and fatigue. At very high doses, magnesium can be fatal.
A blood test will be ordered to check your magnesium level. Normal range is 1.3 to 2.1 mEq/L (0.65 to 1.05 mmol/L). Other blood and urine tests that may be done include: Calcium blood test.
Chronic magnesium deficiency is often associated with normal serum magnesium despite deficiency in cells and in bone; the response to oral supplementation is slow and may take up to 40 weeks to reach a steady state.
"Research has shown that magnesium supplementation may affect the brain functions that help lower stress and anxiety," Gorin says. It works by helping your body kick into the "rest and digest" state, or by activating your parasympathetic nervous system.
Magnesium for sleep
Some studies have found that magnesium supplements can: Make it easier to fall asleep. Improve sleep quality. Reduce symptoms of restless legs syndrome, which can interfere with a good night's sleep.
From regulating mood, maintaining healthy heartbeat to supporting sleep, muscle and nerve function along with energy production to name just a few. It's clear the mineral is vital for both men and women.
It's important not to have more than the recommended amount of magnesium, as it can cause diarrhoea, nausea or abdominal cramps. Extremely high levels can lead to an irregular heartbeat or cardiac arrest.
You can test your magnesium levels by purchasing a simple at-home finger prick test kit which is then analysed at an accredited lab. Forth offers a number of blood tests which include magnesium such as our Nutri-check test and Menopause Health blood test.
The benefits of magnesium supplementation in healthy individuals aren't clear, but Dr. Nassar says that taking a magnesium supplement every day likely isn't unsafe for most people. Just be sure you're not taking too much magnesium. The maximum dietary allowance for most adults is around 400 mg or less.
Medical research has linked magnesium to reduced anxiety. Magnesium helps you to relax by stimulating the production of melatonin and serotonin which boost your mood and help you sleep. Magnesium also reduces the production of cytokines and cortisol, which lead to increased inflammation and stress.
One of the side effects of magnesium might be drowsiness. In this case, you should consider magnesium supplementation at the end of the day (with dinner) to prevent the midday magnesium slump.
In addition to those health benefits, magnesium can also aid in weight management. A 2013 study in the Journal of Nutrition found that higher magnesium intake was associated with lower levels of fasting glucose and insulin (markers related to fat and weight gain).
As noted previously, magnesium deficiency reduces cardiac Na-K-ATPase, leading to higher levels of sodium and calcium and lower levels of magnesium and potassium in the heart. This increases vasoconstriction in the coronary arteries, which can induce coronary artery spasms, myocardial infarction and arrhythmias.
Thus, the elderly population is especially at risk of magnesium deficiency due to low intake but also increased risk for chronic diseases that predispose to magnesium deficiency (ageing also reduces magnesium absorption from the diet, ie, achlorhydria).
"The people at highest risk for low magnesium are those with diarrhea and other forms of malabsorption," like Crohn's disease and celiac disease, says Dr.
