Phytates (phytic acid) in whole grains, seeds, legumes, some nuts—can decrease the absorption of iron, zinc, magnesium, and calcium. [2,3]
Phytates in the diet bind to magnesium and impair its absorption. However the quantities present in normal diet do not affect magnesium absorption. Other dietary factors that are thought to affect magnesium absorption are oxalate, phosphate, proteins, potassium and zinc.
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.
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.
Hypokalemia and Hyperkalemia
Magnesium depletion typically occurs after diuretic use, sustained alcohol consumption, or diabetic ketoacidosis.
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.
Magnesium glycinate is one of the most absorbable forms of magnesium and has fewer GI side effects than other forms.
Nutritionist Carolyn Dean points out that hypothermia isn't the only negative side affect of drinking too much water: “Clear urine may mean you're drinking too much water, and therefore, you're losing essential minerals like magnesium — lighter shades of yellow (rather than totally clear) tend to show that you're ...
Although the functions of vitamin C and magnesium may not overlap like other nutrients, there's no harm in taking them simultaneously. With no known interactions, vitamin C and magnesium can safely be supplemented together.
Lactose doesn't block magnesium absorption. A study in live healthy human subjects found that the presence of lactose, even in large amounts, had no effect on magnesium absorption. Calcium doesn't block magnesium absorption. The body uses separate pathways to absorb each.
Zinc. Zinc and magnesium work to each other's advantage when taken in the right doses. Taking them together is so popular that a lot of oral supplements combine the two. Magnesium helps your body regulate its zinc levels, while zinc enables it to absorb magnesium more efficiently.
Magnesium and vitamin D
One important function and benefit of vitamin D is that it helps the body absorb calcium, which in turn plays a part in how your body absorbs magnesium.
Drinking Coffee – Drinking coffee lowers your calcium and magnesium levels. Many people can be dependent on drinking coffee, and that is understandable, seeing its wide range of benefits from keeping us awake, and raising our body's levels of antioxidants.
Magnesium assists your body in regulating zinc levels, but high intakes of zinc can be detrimental to magnesium absorption – only abnormally high doses (around 142 mg of zinc per day) will reduce magnesium absorption.
Magnesium deficiency is diagnosed via a blood test and sometimes a urine test. Your doctor may order the blood test if you have symptoms such as weakness, irritability, abnormal heart rhythm, nausea and/or diarrhoea, or if you have abnormal calcium or potassium levels.
Every organ in the body, especially the heart, muscles, and kidneys, needs the mineral magnesium. It also contributes to the makeup of teeth and bones. Magnesium is needed for many functions in the body. This includes the physical and chemical processes in the body that convert or use energy (metabolism).
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.
Don't use calcium, zinc, or magnesium supplements at the same time. Also, these three minerals are easier on your tummy when you take them with food, so if your doctor recommends them, have them at different meals or snacks.
Can you take vitamin D and magnesium together? Yes. In fact, it's probably best to take both together. Because so many people have low magnesium levels, vitamin D supplements on their own aren't very helpful for a large portion of the population.
Magnesium assists in the activation of vitamin D, which helps regulate calcium and phosphate homeostasis to influence the growth and maintenance of bones. All of the enzymes that metabolize vitamin D seem to require magnesium, which acts as a cofactor in the enzymatic reactions in the liver and kidneys.
