Magnesium, an essential mineral for overall body function and health, is present in fairly large amounts in the human body: around 25 g, with the majority of it found in the bones. Magnesium is needed for a variety of physiological functions and biochemical reactions in the body, and it is also used to treat certain health conditions, such as kidney stones. Excessive amounts of magnesium can adversely affect kidney health and function, however.
Use
Magnesium is a key component in more than 300 chemical reactions in the body, according to Medline Plus. It also assists with muscle relaxation and the production of protein. Magnesium supplements can be used to treat magnesium deficiency, and it's also used in laxatives. It has been used to treat kidney stones as well as a variety of other conditions, such as migraine headaches, osteoporosis, asthma, anxiety and chronic fatigue syndrome. Using magnesium to treat any condition without first consulting your doctor is not advised.
Sources
Magnesium can be found naturally in a variety of foodstuffs. Good sources of magnesium include legumes, seeds, nuts, soy products, whole grains and dark leafy green vegetables. Magnesium can also be taken as part of a multivitamin or as a magnesium supplement.
Kidney Stones
Medline Plus lists magnesium as being possibly effective for treating kidney stones. Limited scientific evidence demonstrates that magnesium may be useful in preventing the recurrence of kidney stones as well. However, it is highly likely that other medications are more effective. Consult your medical professional before choosing to use magnesium as a treatment for kidney stones.
Kidney Complications
Toxicity from excessive magnesium consumption is rare, as the body can easily rid itself of excess magnesium. However, people with kidney problems such as kidney failure run a greater risk of accumulating excess levels of magnesium in the body. This is because poorly functioning kidneys can result in difficulty ridding the body of magnesium. Medline Plus does not recommend taking magnesium supplements if you suffer from kidney trouble. Consult your doctor before taking any magnesium supplements to avoid any possible complications.
