How long does the magnesium citrate stay in your system?

The time required for your body to eliminate magnesium citrate varies. It depends on the dose, the formulation and other factors that improve or inhibit magnesium absorption.

Jump at the main dishes to remember.

How your body manages magnesium

To understand how long the magnesium citrate stays in your body, it is useful to know how your body absorbs, stores and eliminates magnesium.

  • Your body quickly absorbs magnesium. After taking magnesium, your small intestine absorbs it in about an hour. Your body absorbs around 80% of magnesium after six hours.
  • Your body closely regulates magnesium levels Through your intestines, bones and kidneys.
  • Your bones and fabrics are primary storage sites. About half of the magnesium is stored in your bones, which releases magnesium in your blood if your levels are low. The rest remains mainly in your muscles and soft tissues, while less than 1% is in your blood.
  • Your body eliminates any excess magnesium through your urine.

The duration of magnesium megniusium remains in your body depends on several factors.

1. Your individual magnesium status

The amount of magnesium that your body absorbs may depend on your current levels. If you are deficient, your body can work harder to keep it, absorbing more from your intestines and your urine. The right supplement, like magnesium citrate, can help bring your levels back.

2. The type of magnesium you take

The type of magnesium you take affects how it is absorbed, which can influence the duration of your system.

For example, organic forms of magnesium (such as magnesium citrate) tend to be absorbed more easily than inorganic forms (such as magnesium oxide).

Tablets, capsules and soft of magnesium citrate tablets can reconstruct magnesium levels. Constipation treatments (i.e. magnesium citrate solution) are not intended to help reconstruct the levels.

3. All the health conditions you may have

Health conditions and lifestyle factors can disrupt the balance of magnesium by reducing absorption or increasing loss. This can have an impact on the duration of magnesium in your system or has it accumulated.

  • Vitamin D deficiency reduces the absorption of magnesium.
  • Diarrhea and vomiting Remove the magnesium from your body.
  • Gastrointestinal diseases Like celiac disease, Crohn’s disease and colitis can cause low magnesium levels due to chronic diarrhea.
  • Diabetes mellitus / insulin resistance Can cause high levels of blood sugar in the kidneys, resulting in greater loss of magnesium through your urine.
  • Alcohol consumption disorder May lead to a decrease in dietary intake, gastrointestinal problems, vomiting, a depletion of phosphate, renal dysfunction and vitamin D deficiency. These can all contribute to magnesium deficiency.
  • Kidney diseaseparticularly In serious cases, may increase the risk of high magnesium levels because the body has trouble getting rid of excess magnesium.

4. How many magnesium citrate you take

The quantity of magnesium citrate that you take may have a direct impact over the duration of the duration of your body. The larger doses are not always better; Your body can absorb less when you take too much at the same time.

  • Magnesium absorption decreases with higher doses. Your body can absorb less magnesium citrate when you take more.
  • Smaller and more frequent doses can improve absorption. The absorption of magnesium is higher when taken in several low doses throughout the day than when it is taken in a large dose.
  • Absorption rates may vary considerably depending on the size of the dosage. A study showed that 65% of magnesium was absorbed by a daily dose of 36 milligrams (MG), while only 11% were absorbed by a daily dose of 973 mg.
  • Be aware of your daily needs. Adult males need 400 to 420 mg of magnesium per day. Adult women need 310 to 320 mg per day.
  • Too much magnesium of food supplements– on 350 mg per day for adults – can cause diarrhea, nausea and stomach cramps.

5. Drugs you can take

Some drugs can interfere with the way your body absorbs or eliminates magnesium citrate. This can shorten or prolong the magnesium time in your system.

Medicines that reduce magnesium levels include the following:

  • Antibiotics: Amoxicillin, zithromax (azithromycin), vibramycin (doxycycline), levainquin (levofloxacin), cipro (ciprofloxacin), antibiotics aminoglycosides
  • Proton pump inhibitors: Prilosec (omeprazole)
  • Blood pressure drugs: Apresolina (hydralazine) plus ECA inhibitors (for example, Zestril or Lisinopril) with hydrochlorothiazide
  • Diuretics or water pills: Lasix (furosemide)
  • Histamine-2 receptor blockkers: Pepcid (Famotidine)
  • Corticosteroids: Decadron (Dexamethasone), Deltasone (prednisone)
  • Estrogens: Drugs containing estradiol and estrogens
  • Crisis drugs: Dilantine (phenytoin), phenobarbital
  • Heart medication: PALERONE (Amiodarone)
  • Immunosuppressants: Neoral (cyclosporine), program (tacrolimus)
  • Stimulants: Ritalin (methylphenidate)

6. Other supplements you take

Certain supplements can interfere with the absorption of magnesium, especially in high doses. This can affect the amount of magnesium citrate that your body keeps and for how long:

  • Calcium
  • Phosphorus
  • Iron
  • Copper
  • Manganese
  • Zinc

7. Specific foods you eat

What you eat can affect the amount of magnesium citrate that your body absorbs and how fast it can eliminate it. Some foods block absorption, while others can speed up the loss of magnesium.

Specific foods decrease the absorption of magnesium:

  • Foods containing oxalate: Spinach, cabbage, broccoli, Brussels germs
  • Food containing phytate: Bran and whole bread
  • Partially and non -fermentable fibers: Wheat wheat, as well as hemicellulose, cellulose and lignin found in specific grains, fruits and vegetables

Food diets and drinks can increase the elimination of magnesium by your kidneys:

8. Your age

As you get older, changes in your body and diet can make it more difficult to maintain the level of magnesium stable. This may have an impact on the duration of the duration of the magnesium citrate in your system.

The risk of deficiency can increase with age due to the following elements:

  • Lower magnesium arping
  • Decrease in absorption
  • Increase in renal excretion

In the United States, food supplements are not regulated such as prescription drugs, so some may not have the ingredients listed on the label. To ensure quality, choose supplements tested or certified by groups such as NSF, US Pharmacopeia or Consumerlab.com. For personalized advice, talk to your health care provider, your dietitian or your pharmacist.

Main to remember

  • The time required to the body to remove magnesium from your system is not clear due to various factors.
  • Magnesium status, type of magnesium, health problems, dose, medicines, other supplements, food and age can have an impact on the absorption of magnesium.
  • Magnesium citrate is generally more absorbable than inorganic forms.
