Does Taking Magnesium Make You Urinate More Frequently?

Magnesium is a mineral essential for healthy immune function, strong bones, heart health and proper nerve and muscle function. There are no adverse effects from consuming dietary magnesium -- magnesium found in the foods you eat -- but if you consume too much in the form of supplements or antacids, it can be unhealthy. However, one thing that taking magnesium doesn't do is cause you to urinate more frequently than usual.
About half of the magnesium in your body is found in your bones, and most of the rest of it is in your organs and other tissues. Only about 1 percent of the magnesium in your body is in your blood. In addition to keeping your heart, bones, muscles, nerves and immune system healthy, magnesium also helps regulate your blood sugar and helps maintain a healthy blood pressure. You absorb dietary magnesium through your small intestine and excrete it through your kidneys.
Getting Enough Magnesium
Adult men should get between 400 and 420 milligrams of magnesium per day; women should get between 310 and 320 milligrams per day. Magnesium is found in leafy green vegetables, nuts, legumes, whole grains, beans, dairy products and brown rice. Eating a diet rich in these foods can help you get enough magnesium, though it's common for the adults in the United States to have a magnesium deficiency. The deficiency rarely causes symptoms.
Severe Magnesium Deficiency
Conditions such as diabetes and kidney disease can cause you to become very low in magnesium because your kidneys are unable to regulate how much magnesium stays in your body. They flush too much of it out, leading to illness. Symptoms of a severe magnesium deficiency include fatigue, weakness, loss of appetite, nausea and vomiting. As the deficiency gets worse, you may experience seizures, abnormal heart rhythms, numbness and tingling in your body, muscle cramps, heart spasms and personality changes. In addition to illness, magnesium deficiency can be caused by some antibiotics, diuretics and cancer medications. Alcoholics are also at risk for a severe magnesium deficiency. People with a severe deficiency may need to take supplements to restore and maintain a healthy level of magnesium in their bodies.
Too Much Magnesium
You really can't get too much magnesium from your diet, but if you take a magnesium supplement or an antacid with magnesium in it, too much can cause symptoms similar to magnesium deficiency. Before you begin taking magnesium supplements, visit your doctor to determine whether you have a deficiency that needs to be treated. If you are told to take magnesium, be sure to take it exactly as directed and tell your doctor if you experience any symptoms of taking too much.
What Causes Frequent Urination
If you're urinating more frequently than usual, it's not the result of too much magnesium, but you need to find out why it's happening. Frequent urination is a common and normal symptom of pregnancy. Urinating frequently may be the natural result of drinking more liquids than usual, or could be the result of consuming too much caffeine. Urinating frequently along with an urgency to go could be an indicator that you have a bladder or urinary tract infection. Anxiety can also cause frequent urination. Sometimes, a serious condition such as enlarged prostate or diabetes is responsible for frequent urination; occasionally, bladder cancer is behind your frequent trips to the bathroom.
When to Seek Help
If you haven't been drinking more than usual and aren't pregnant, you should talk to your doctor about more frequent urination. It's especially important to call your doctor if you have pain while you urinate, pain in your side or back, bloody or cloudy urine, vomiting, chills or shakiness, or if the frequency and urgency of urination have made you change your lifestyle.
