According to National Institutes of Health online medical encyclopedia Medline Plus, magnesium is an essential nutrient that helps with protein production, contraction and relaxation of your muscles and enzyme functions. Magnesium is found in foods such as halibut, green leafy vegetables, fruits, nuts, seeds, legumes, soy products and whole grains. Most multivitamin supplements also contain magnesium. If you’re deficient in magnesium, you could suffer serious side effects, so talk to your doctor about ways to increase the magnesium in your body.

If you don’t consume enough magnesium on a daily basis, you could suffer early, moderate or severe symptoms of magnesium deficiency. According to Medline Plus, early symptoms of magnesium deficiency include muscle twitching, poor cognition, irritability, fatigue and confusion, while moderate and sever symptoms include rapid heartbeat, numbness, tingling, hallucinations and delirium.
The length of time it takes to reduce symptoms of magnesium deficiency after increasing your magnesium consumption depends on the method used to increase magnesium levels in your body. The National Institutes of Health Office of Dietary Supplements reports that if magnesium levels in your body are low, increasing dietary intake of magnesium from foods may not be enough to help restore your magnesium levels to normal amounts and intravenous magnesium or prescription magnesium tablets may be indicated by your doctor.
If your doctor recommends intravenous magnesium to help increase your blood magnesium levels, you’ll likely feel benefits of magnesium injections soon after they occur, although the exact time it will take may vary. Compared with consuming magnesium from foods, intravenous magnesium injections or prescription magnesium tablets are a quicker and more effective way to help increase your blood magnesium levels and magnesium stores in your body.
To help reduce unpleasant and dangerous side effects from magnesium deficiency, consume adequate amounts of magnesium on a daily basis in your diet or through supplements. According to the Institute of Medicine, magnesium recommended dietary allowances for magnesium are 400 milligrams per day for men ages 19 to 30, 420 milligrams per day for men ages 31 and up, 310 milligrams per day for women ages 19 to 30, 320 milligrams per day for women ages 31 and up, 350 milligrams per day for pregnant women ages 19 to 30, 360 milligrams per day for pregnant women ages 31 and up, 310 milligrams per day for nursing women ages 19 to 30 and 320 milligrams per day for nursing women ages 31 and up.
