- Magnesium is a mineral that is present in relatively large amounts in the body. Magnesium is important in more than 300 chemical reactions that keep the body working properly. People get magnesium from their diet, but sometimes magnesium supplements are needed if magnesium levels are too low. Dietary intake of magnesium may be low, particularly among women.
- An easy way to remember foods that are good magnesium sources is to think fiber. Foods that are high in fiber are generally high in magnesium.
- Sources of magnesium include legumes, whole grains, vegetables (especially broccoli, squash, and green leafy vegetables), seeds, and nuts (especially almonds). Other sources include dairy products, meats, chocolate, and coffee. Water with a high mineral content, or “hard” water, is also a source of magnesium.
- Dyspepsia (heartburn or “sour stomach”) as an antacid. Various magnesium compounds are used. Magnesium hydroxide seems to work the fastest.
- Preventing and treating magnesium deficiency, and certain conditions related to magnesium deficiency.
- Use as a laxative for constipation or preparation of the bowel for surgical or diagnostic procedures.
- Diseases of the heart and blood vessels including chest pain, irregular heartbeat, high blood pressure, high levels of “bad” cholesterol called low-density lipoprotein (LDL) cholesterol, low levels of “good” cholesterol called high-density lipoprotein (HDL) cholesterol, heart valve disease (mitral valve prolapse), and heart attack.
- Attention deficit-hyperactivity disorder (ADHD)
- Chronic fatigue syndrome (CFS)
- Lyme disease
- Leg cramps during pregnancy
- Kidney stones
- Migraine headaches
- Weak bones (osteoporosis)
- Premenstrual syndrome (PMS)
- Altitude sickness
- Urinary incontinence
- Restless leg syndrome
- Multiple sclerosis
- Preventing hearing loss.
- Athletes sometimes use magnesium to increase energy and endurance.
- Some people put magnesium on their skin to treat infected skin ulcers, boils, and carbuncles; and to speed up wound healing.
- Magnesium is also used as a cold compress in the treatment of a severe skin infection caused by strep bacteria (erysipelas) and as a hot compress for deep-seated skin infections.
- Magnesium is required for the proper growth and maintenance of bones. Magnesium is also required for the proper function of nerves, muscles, and many other parts of the body.
- In the stomach, magnesium helps neutralize stomach acid and moves stools through the intestine.
Moderate Interaction Be cautious with this combination:
- Antibiotics (Aminoglycoside antibiotics) interacts with MAGNESIUM: Some antibiotics can affect the muscles. These antibiotics are called aminoglycosides. Magnesium can also affect the muscles. Taking these antibiotics and getting a magnesium shot might cause muscle problems.
- Some aminoglycoside antibiotics include amikacin (Amikin), gentamicin (Garamycin), kanamycin (Kantrex), streptomycin, tobramycin (Nebcin), and others.
- Antibiotics (Quinolone antibiotics) interacts with MAGNESIUM: Magnesium might decrease how much antibiotic the body absorbs. Taking magnesium along with some antibiotics might decrease the effectiveness of some antibiotics. To avoid this interaction take these antibiotics at least 2 hours before, or 4 to 6 hours after, magnesium supplements.
- Some of these antibiotics that might interact with magnesium include ciprofloxacin (Cipro), enoxacin (Penetrex), norfloxacin (Chibroxin, Noroxin), sparfloxacin (Zagam), trovafloxacin (Trovan), and grepafloxacin (Raxar).
- Antibiotics (Tetracycline antibiotics) interacts with MAGNESIUM: Magnesium can attach to tetracyclines in the stomach. This decreases the amount of tetracyclines that the body can absorb. Taking magnesium along with tetracyclines might decrease the effectiveness of tetracyclines. To avoid this interaction take calcium 2 hours before or 4 hours after taking tetracyclines.
- Some tetracyclines include demeclocycline (Declomycin), minocycline (Minocin), and tetracycline (Achromycin).
- Bisphosphonates interacts with MAGNESIUM: Magnesium can decrease how much bisphosphate the body absorbs. Taking magnesium along with bisphosphates can decrease the effectiveness of bisphosphate. To avoid this interaction take bisphosphonate at least two hours before magnesium or later in the day.
- Some bisphosphonates include alendronate (Fosamax), etidronate (Didronel), risedronate (Actonel), tiludronate (Skelid), and others.
- Medications for high blood pressure (Calcium channel blockers) interacts with MAGNESIUM: Magnesium might decrease blood pressure. Taking magnesium with medication for high blood pressure might cause your blood pressure to go too low.
- Some medications for high blood pressure include nifedipine (Adalat, Procardia), verapamil (Calan, Isoptin, Verelan), diltiazem (Cardizem), isradipine (DynaCirc), felodipine (Plendil), amlodipine (Norvasc), and others.
- Muscle relaxants interacts with MAGNESIUM: Magnesium seems to help relax muscles. Taking magnesium along with muscle relaxants can increase the risk of side effects of muscle relaxants.
- Some muscle relaxants include carisoprodol (Soma), pipecuronium (Arduan), orphenadrine (Banflex, Disipal), cyclobenzaprine, gallamine (Flaxedil), atracurium (Tracrium), pancuronium (Pavulon), succinylcholine (Anectine), and others.
- Water pills (Potassium-sparing diuretics) interacts with MAGNESIUM: Some “water pills” can increase magnesium levels in the body. Taking some “water pills” along with magnesium might cause too much magnesium to be in the body.
- Some “water pills” that increase magnesium in the body include amiloride (Midamor), spironolactone (Aldactone), and triamterene (Dyrenium).
