Um magnesium is NOT a drug my darlin' it's a mineral. :D
The mineral magnesium is important for every organ in the body, particularly the heart, muscles, and kidneys. It also contributes to the composition of teeth and bones. Most importantly, it activates enzymes, contributes to energy production, and helps regulate calcium levels as well as copper, zinc, potassium, vitamin D, and other important nutrients in the body.

Magnesium is available in many foods. However, most people in the United States probably do not get as much magnesium as they should from their diet. Magnesium is found in whole unprocessed foods in the diet. However, different methods for calculating amounts of magnesium in foods have often lead to conflicting results. In addition, not all foods have been thoroughly analyzed.

Too much coffee, soda, salt, or alcohol intake as well as heavy menstrual periods, excessive sweating, and prolonged stress can also lower magnesium levels.


Getting enough magnesium may help facilitate the results of conventional treatment for the following conditions:

Attention Deficit/Hyperactivity Disorder (ADHD)
Some experts believe that children with ADHD may be exhibiting the effects of mild magnesium deficiency (such as irritability, decreased attention span, and mental confusion). In one study of 116 children with ADHD, 95% were magnesium deficient. In a separate study, 75 magnesium-deficient children with ADHD were randomly assigned to receive magnesium supplements in addition to standard treatment or standard treatment alone for 6 months. Those who received magnesium demonstrated a significant improvement in behavior, whereas those who received only standard therapy without magnesium exhibited worsening behavior.

These results suggest that magnesium supplementation, or at least high amounts of magnesium in the diet, may prove to be beneficial for children with ADHD.

Type 2 diabetes is associated with low levels of magnesium in the blood. In addition, at least one small study suggests that taking magnesium supplements may improve the action of insulin and decrease blood sugar levels, particularly in the elderly.

Results of a preliminary study including 24 people with fibromyalgia suggest that a proprietary tablet containing both malic acid and magnesium may improve pain and tenderness associated with this health condition when taken for at least 2 months. Others suggest that the combination of calcium and magnesium may be helpful for some people with fibromyalgia.

Heart Disease
Magnesium is essential to heart health. This mineral is particularly important for maintaining a normal heart rhythm and is often used by physicians to treat irregular heartbeat (arrythmia). People with congestive heart failure (CHF) are often at particular risk for developing an arrhythmia. For this reason, your doctor may determine that magnesium should be a part of the treatment of CHF.

High Blood Pressure
Eating low fat dairy products along with lots of fruits and vegetables on a regular basis is associated with lower blood pressure. All of these foods are rich in magnesium as well as calcium and potassium. Singling out which of these nutrients is responsible for lowering blood pressure is difficult. In addition, studies using magnesium supplements have not demonstrated a reduction in blood pressure. Consequently, the key is to obtain magnesium, along with the other important minerals, from the diet.

Inflammatory Bowel Disease (IBD)
People with IBD (particularly ulcerative colitis) may have low magnesium levels. In addition, there is some early evidence that dietary magnesium supplements may be of some value for preventing IBD flare-ups.

Infertility and Miscarriage
A small study of infertile women as well as women with a history of miscarriage found that low levels of magnesium may impair reproductive function and increase the risk for miscarriage. The authors of the study suggest that one aspect of the treatment of infertility (particularly in women with a history of miscarriage) should include magnesium along with selenium. More research in this area is needed. In the meantime, check your prenatal vitamin for selenium and magnesium content and talk to your doctor about the proper amounts.

Because magnesium improves the absorption of calcium from the gastrointestinal tract, some practitioners suggest that women take calcium and magnesium together at a ratio of 2:1, particularly around the time of menopause. This helps prevent loss of bone mass.

In addition, as estrogen levels drop during menopause, magnesium levels seem to diminish as well. For this reason, magnesium may also help to relieve some menopausal symptoms such as hot flashes. More research is needed.

Migraine Headache
Magnesium levels tend to be lower in those with migraine headaches, including children and teenagers, when compared to those with tension headaches or no headaches at all. In addition, a few studies suggest that magnesium supplements may decrease the length of time that one suffers from a migraine and reduces the amount of medication needed.

Some experts suggest that oral magnesium may be an appropriate alternative to prescription medication for people who suffer from migraine headaches. Other experts suggest that combining magnesium with the herb feverfew along with vitamin B2 (riboflavin) may be particularly helpful when you have a headache.

In addition, magnesium supplements may prove to be a welcome option for migraine sufferers who cannot tolerate medications due to side effects or who can't take migraine medications due to pregnancy or heart disease. These issues are under scientific investigation.

Calcium, vitamin D, magnesium, and other micronutrient deficiencies are believed to play a role in the development of osteoporosis. Adequate intake of calcium, magnesium, and vitamin D coupled with overall proper nutrition and weight-bearing exercise throughout childhood and adulthood are the primary preventive measures for this condition, in both men and women.

Preeclampsia and Eclampsia
Intravenous magnesium sulfate is commonly used to prevent complications from preeclampsia and eclampsia. Preeclampsia is a condition characterized by a sharp rise in blood pressure during the third trimester of pregnancy. Women with preeclampsia may develop seizures, which is then called eclampsia. Magnesium, administered in the hospital, is the treatment of choice to prevent or treat seizures associated with eclampsia.

Premenstrual Syndrome (PMS)
Scientific evidence and clinical experience suggest that magnesium supplements may help relieve symptoms associated with PMS, particularly bloating, leg swelling, weight gain, and breast tenderness. Preliminary information suggests that magnesium may be helpful for alleviating mood swings as well.

Population based information suggests that people with low magnesium in their diet may be at greater risk for stroke. Some preliminary scientific evidence suggests that magnesium sulfate may be helpful in the treatment of a stroke or transient ischemic attack (TIA; a temporary disturbance of blood supply to an area of the brain). More research is needed to know for certain if use of this mineral following a stroke or TIA is helpful.

A study found that magnesium improved insomnia related to [SIZE=2][COLOR=DarkRed]restless legs syndrome[/COLOR] [/SIZE] (a disorder characterized by uncomfortable sensations in the legs, which are worse during periods of inactivity or rest or while sitting or lying down). In another study including 42 patients undergoing abdominal hysterectomy, those who received intravenous magnesium sulfate before and after surgery required fewer pain-killers, experienced less discomfort, and slept better after surgery compared to those who received placebo.

Dietary Sources

Rich sources of magnesium include tofu, legumes, whole grains, green leafy vegetables, wheat bran, Brazil nuts, soybean flour, almonds, cashews, blackstrap molasses, pumpkin and squash seeds, pine nuts, and black walnuts. Other good dietary sources of this mineral include peanuts, whole wheat flour, oat flour, beet greens, spinach, pistachio nuts, shredded wheat, bran cereals, oatmeal, bananas, and baked potatoes (with skin), chocolate, and cocoa powder. Many herbs, spices, and seaweeds supply magnesium, such as agar seaweed, coriander, dill weed, celery seed, sage, dried mustard, basil, cocoa powder, fennel seed, savory, cumin seed, tarragon, marjoram, poppy seed.

How to Take It

Magnesium is generally recommended in small doses 3 to 6 times throughout the day, with a full glass of water with each dose to avoid diarrhea. Be sure to check with your healthcare provider before taking magnesium supplements and before considering them for a child. Under certain circumstances, such as certain heart arrhythmias and preeclampsia, a physician will have magnesium administered intravenously in the hospital.

Digitalis is a drug and an herb. It can kill you or it can stop atrial fibrillation. There is a popular belief that if something is "natural" or the body uses it, it is safe to use as much as you want but this is not true. Look it up in medical texts. Too much potassium will kill you. It is a mineral that the body needs but they use it to stop the heart when carrying out the death penalty. Too much sodium causes edema and hypernatremia among other things. Ephedra causes weight loss and heart problems. The point I am trying to make is that minerals in excess can cause serious problems. There are several causes for restless legs, not all of them apply to everyone. If you choose to disbelive research as a basis for facts, what do you base your facts on? I am well aware of what magnesium is used for in the body, but that doesn't mean I lack it. I know what iron is used for, what causes anemia, and the connection between anemia and restless legs, but I don't take huge quantities of iron because that could cause nerve damage. You have a right to your opinion, but before you advise a pregnant woman to take a large amount of any mineral, you should advise she check with her doctor.
