You may not take these nutrients with magnesium at the same time

Magnesium is needed in more than 300 processes in the body. At a Deficiency can make diffuse symptoms arise – for example fatigue and Muscle cramps. Also to prevent Magnesium can be helpful. Many Athletes therefore take magnesium Supporting training. But are there interactions with other nutrients?

Which nutrients should not be taken together with Magnesium?

According to the Society for Magnesium Research, there is above all a negative interaction: iron. Magnesium should not be taken with iron at the same time, since the two minerals can compete in the intestine. However, this does not apply to all magnesium connections, but only on inorganic Magnesium connectionslike magnesium oxide and magnesium carbonate. « With organic magnesium compounds (e.g. magnesium citrate, magnesium aspartity) there is no indication of an interaction with iron, » the experts tell us. If you take organic magnesium compounds and iron preparations, you should keep a time interval of about two to three hours. The Time of intake is at magnesium But generally no matter.

According to the Linus Pauling Institute The Oregon State University have the following interactions between magnesium and other nutrients:

Li): Relative List-None (&> Li): PL- (1.2EM) (&> Li): Marker: Text- (0) (&> Li): Relative (&> Li): Before: Absolute (&> Li): Before: W-3 (&> Li): Before: H-3 (&> Li): Before: BG-fire (& Li): Before: LEFT-0 (&> Li): Before: Top- (8px) (&> Li): Before: Rounded-Full My-5 « >
• zinc: High doses (e.g. 142 mg/day) reduce the magnesium intake. Such high doses are not achieved in everyday life, so it must therefore be taken when taking it No time interval between magnesium and zinc be adhered to.
• Fiber: A greatly increased supply can reduce the utilization of magnesium. However, the actual relevance in everyday life is unclear, since this was mainly observed in laboratory experiments.
• protein: An insufficient protein intake (
• Vitamin D: The active form (calcitriol) can slightly increase magnesium intake.
• Calcium: According to the studies, a high calcium intake generally does not affect magnesium balance. It is rather the other way around: a magnesium deficiency can probably lead to a calcium deficiency. « Contrary to differently, magnesium and calcium preparations in the usual doses can be taken together, » says the Society for Magnesium Research.

« In general, the problem of interactions in the area of ​​nutritional supplement is less relevant. Because this is (only) a support of nutrient care, not against the medical treatment of deficiency states, » says the Society for Magnesium Research.

Which drugs should not be taken together with Magnesium?

As the Society for Magnesium Research informed us on request, there are the following drugs that should not be taken at the same time as Magnesium:

Li): Relative List-None (&> Li): PL- (1.2EM) (&> Li): Marker: Text- (0) (&> Li): Relative (&> Li): Before: Absolute (&> Li): Before: W-3 (&> Li): Before: H-3 (&> Li): Before: BG-fire (& Li): Before: LEFT-0 (&> Li): Before: Top- (8px) (&> Li): Before: Rounded-Full My-5 « >
• Tetracycline (broadband antibiotics)
• Sodium
• Thyroid hormones

The Linus Pauling Institute lists a selection of the following medicines, which can lead to interactions with magnesium:

Digoxin (heart remedy):

Li): Relative List-None (&> Li): PL- (1.2EM) (&> Li): Marker: Text- (0) (&> Li): Relative (&> Li): Before: Absolute (&> Li): Before: W-3 (&> Li): Before: H-3 (&> Li): Before: BG-fire (& Li): Before: LEFT-0 (&> Li): Before: Top- (8px) (&> Li): Before: Rounded-Full My-5 « >
• Nitrofurantoin (antibiotic),
• Antimalaria
• Bisphosphonates (e.g. alendronate),
• Chloricpromazine (neuroleptic),
• Penicillamin (at rheumatism),
• Oral anticoagulants (blood thinners)

Antibiotics from the groups:

Li): Relative List-None (&> Li): PL- (1.2EM) (&> Li): Marker: Text- (0) (&> Li): Relative (&> Li): Before: Absolute (&> Li): Before: W-3 (&> Li): Before: H-3 (&> Li): Before: BG-fire (& Li): Before: LEFT-0 (&> Li): Before: Top- (8px) (&> Li): Before: Rounded-Full My-5 « >
• Chinolone, e.g. B. ciprofloxacin,
• Tetracycline, e.g. B. doxycycline

Others too Medicines can withdraw magnesium to the body. Magnesium can also increase the effect of muscle relaxants in anesthesia, which is why the Linus Pauling Institute advises, before an operation Taking magnesium to address.

What many people take, but can also lead to interactions when taking it in the long term, are proton pump inhibitors (PPI) that are prescribed for heartburn or gastritis. They cause magnesium losses over the kidneys, which is why patients in the long run Magnesium deficiency can slip. Also on other nutrients, such as Vitamin B12 should be taken when taking PPIs be observed.

By the way: serious Side effects of magnesium are rather rare. Before it becomes harmful, you usually get Diarrhea.
