milk depresses Mg and Ca bioavailability, as would be predicted on the basis of reported effects of their purified components.
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.
Research suggests that high dairy consumption may reduce magnesium levels in the body. Milk and cheese both contain high quantities of calcium which may block magnesium absorption in some people.
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.
Magnesium deficiency in healthy people is rare but it can be caused by: a poor diet (especially in elderly people or those who don't have enough to eat) type 2 diabetes. digestive problems such as Crohn's disease.
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.
Antibiotics: Taking magnesium supplements may reduce the absorption of quinolone antibiotics, tetracycline antibiotics, and nitrofurantoin (Macrodandin). Magnesium should be taken 1 hour before or 2 hours after taking these medications. Quinolone and tetracycline antibiotics include: Ciprofloxacin (Cipro)
With heavy alcohol intake, there can be a loss of magnesium from tissues and increased urinary loss (Pasqualetti et al., 1987; Shane and Flink, 1991). Chronic alcohol abuse has been reported to deplete the total body supply of magnesium (Vandemergel and Simon, 2015).
Although magnesium is found within milk, it may not be in your best interest to consume a magnesium supplement with a glass of milk. Magnesium and calcium have a complicated relationship. Both minerals have overlapping transport systems within the body, so when consumed together they compete for absorption.
High doses of magnesium from supplements or medications can cause nausea, abdominal cramping and diarrhea. In addition, the magnesium in supplements can interact with some types of antibiotics and other medicines.
Hypokalemia and Hyperkalemia
Magnesium depletion typically occurs after diuretic use, sustained alcohol consumption, or diabetic ketoacidosis.
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.
Fresh raw milk – Milk, which is also rich in potassium, protein, vitamin B12 (cobalamin), and vitamin D, is chock-full of magnesium. It supports bone health. One cup of fresh raw milk has 27.8 mg of magnesium.
People with diabetes, intestinal disease, heart disease or kidney disease should not take magnesium before speaking with their health care provider. Overdose. Signs of a magnesium overdose can include nausea, diarrhea, low blood pressure, muscle weakness, and fatigue. At very high doses, magnesium can be fatal.
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.
Reactions With
Oxygen: When exposed to oxygen, magnesium turns into magnesium oxide. Hydrogen: When exposed to hydrogen, magnesium turns into magnesium hydride. Nitrogen: When reacted with nitrogen, magnesium turns into magnesium nitride. Halogens: When reacted with a halogen, magnesium is very reactive.
Therefore, conditions that affect the gut and digestion, like celiac disease, chronic pancreatitis, Crohn's disease, and cystic fibrosis, can reduce vitamin D absorption.
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.
