As a general rule, foods that are high in fibre provide magnesium. Some good sources of magnesium include leafy green vegetables — such as spinach — legumes, nuts, seeds and whole grains. Tap, mineral, and bottled waters can also be sources of magnesium, but how much magnesium they contain depends on the brand.
Green leafy vegetables, such as spinach, legumes, nuts, seeds, and whole grains, are good sources [1,3]. In general, foods containing dietary fiber provide magnesium. Magnesium is also added to some breakfast cereals and other fortified foods.
Chronic magnesium deficiency is often associated with normal serum magnesium despite deficiency in cells and in bone; the response to oral supplementation is slow and may take up to 40 weeks to reach a steady state.
How is magnesium deficiency treated? If you have magnesium deficiency, your doctor will prescribe a magnesium supplement. Sometimes these can give you diarrhoea, so your doctor may need to experiment with the dose. In severe cases, intravenous magnesium may be needed.
Common causes of low magnesium include: Alcohol use. Burns that affect a large area of the body. Chronic diarrhea.
Magnesium deficiency is frequently observed in conditions causing steatorrhoea or severe chronic diarrhoea such as Crohn's disease, ulcerative colitis, coeliac disease, Whipple's disease and short bowel syndrome.
If you choose to take magnesium tablets, you'll start to notice significant improvements a week after you start adding the tablets to your daily routine. Transdermal magnesium products begin working straight away, as they are delivered directly to the epidermis.
Deficiencies due to poor absorption of magnesium from the gastrointestinal tract include: Diseases causing malabsorption such as celiac disease and inflammatory bowel disease. Gastric bypass surgery. Hereditary syndromes causing poor absorption of magnesium (primary intestinal hypomagnesemia).
Magnesium glycinate -- Magnesium glycinate (magnesium bound with glycine, a non-essential amino acid) is one of the most bioavailable and absorbable forms of magnesium, and also the least likely to induce diarrhea.
Fruit juices such as orange juice, cherry juice, and watermelon juice are all good sources of magnesium, potassium, and phosphorus. According to the FNDDS, the average school container (124 grams) of 100% orange juice provides : 13.6 mg of magnesium.
Magnesium glycinate is one of the most absorbable forms of magnesium and has fewer GI side effects than other forms.
Vitamin D and calcium
The active form of vitamin D (calcitriol) may slightly increase intestinal absorption of magnesium (6).
You might have trouble absorbing magnesium from food if you drink too much alcohol, have kidney problems, take certain medicines, or have celiac disease or long-lasting digestive problems.
This ongoing process of absorption and utilization is pretty quick, so it's important to make sure you're always giving your body the magnesium it needs. “Most magnesium will stay in the body for anywhere from 12 to 24 hours.
Severe magnesium deficiency can result in: Abnormal heart rhythms. Numbness and tingling. Personality changes.
Mg is essential in the metabolism of vitamin D, and taking large doses of vitamin D can induce severe depletion of Mg. Adequate magnesium supplementation should be considered as an important aspect of vitamin D therapy.
You can test your magnesium levels by purchasing a simple at-home finger prick test kit which is then analysed at an accredited lab. Forth offers a number of blood tests which include magnesium such as our Nutri-check test and Menopause Health blood test.
This overlap in the results suggests that stress could increase magnesium loss, causing a deficiency; and in turn, magnesium deficiency could enhance the body's susceptibility to stress, resulting in a magnesium and stress vicious circle.
