Fifteen patients with Normal Tension Glaucoma (NTG study group) received 300 mg oral magnesium citrate for 1 month, while 15 patients with NTG (control group) received no treatment. In the study group pattern standard deviation improved from 3.6 at baseline to 2.8 at 1 month (p<0.05).>
People get magnesium from their diet, but sometimes magnesium supplements are needed if magnesium levels are too low. Foods that are high in fiber are generally high in magnesium. Dietary 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.
Magnesium is used as a laxative for constipation. It is also used as an antacid for acid indigestion. Some people use magnesium for diseases of the heart and blood vessels including chest pain, irregular heartbeat, high blood pressure, high LDL cholesterol, low HDL cholesterol, heart mitral valve prolapse, and heart attack. Magnesium is also used for treating attention deficit-hyperactivity disorder (ADHD), anxiety, chronic fatigue syndrome (CFS), Lyme disease, fibromyalgia, leg cramps during pregnancy, diabetes, kidney stones, migraine headaches, weak bones (osteoporosis), premenstrual syndrome (PMS), altitude sickness, urinary incontinence, kidney stones, restless leg syndrome, asthma, hayfever, multiple sclerosis, and for preventing hearing loss. Athletes sometimes use magnesium to increase energy and endurance.
In some people, magnesium might cause stomach upset, nausea, vomiting, diarrhea, and other side effects. Doses less than 350 mg per day are safe for most adults. Magnesium is LIKELY SAFE for pregnant or breast-feeding women when taken by mouth in the amounts recommended. Don’t take magnesium if you have kidney problems.
Magnesium may decrease the effectiveness of aminoglycoside antibiotics (tobramycin, gentamycin) and fluoroquinolone antibiotics.
