Magnesium

(Magnesium)

Magnesium is a key part of many of your body’s functions, including those involved in energy production, heart health, brain function, and muscle contraction. Although it is found in foods ranging from green leafy vegetables to nuts, seeds, whole grains, legumes, and soybeans, most Americans do not get enough magnesium in their diet.

While a minor magnesium deficiency might not cause problems, severely low magnesium levels are a risk factor in various health conditions, such as type 2 diabetes (T2DM), osteoporosis, heart disease or cardiovascular disease, and migraine headaches.

Important information about Magnesium

How does Magnesium work?

Magnesium is involved in over 300 enzyme reactions in the human body. It helps regulate levels of calcium, copper, zinc, potassium, vitamin D, and other important nutrients in the body.

Magnesium is necessary for normal bone health and maintenance as well as being essential for nerve and muscle function, as well as many other bodily functions like muscle cramps. Getting enough of this mineral can help prevent or treat chronic diseases.

Magnesium also supports a healthy heart rhythm, strong bones, and appropriate blood pressure. Additionally, it regulates your blood sugar levels and hypomagnesemia (low magnesium levels).

How do you use Magnesium?

Follow all directions given to you by your doctor and read all documents provided, including the full Prescribing Information, FDA-Approved Product Labeling, Instructions for Use, and Medication Guide before using magnesium. However, the following is a synopsis of the general guidelines for the use of magnesium:

  • Magnesium citrate: Take with a full glass of water and shake the liquid medication. Use the supplied measuring equipment to determine the appropriate dose. Magnesium citrate should cause a bowel movement within 30 minutes to 6 hours after taking the medication.
  • Magnesium oxide: When using this medication as a laxative, it may be better to take it at bedtime. Magnesium oxide may be taken with food if it causes stomach distress.
  • Magnesium chloride: Because magnesium chloride is administered by an infusion into a vein, your doctor may want to assess your kidney function before you begin using it. This injection will be administered to you by a healthcare provider. You may be given additional medications to help avoid significant side effects or allergic reactions, and your breathing and blood pressure will be continuously monitored during and after each injection.
  • Magnesium sulfate: Never exceed the prescribed dose of magnesium sulphate on the package label or as directed by your sulfatehealthcare provider. Using too much magnesium sulfate can have disastrous, life-threatening consequences. Magnesium sulfate can be used orally or as a soak. To consume magnesium sulfate orally, dissolve it in water. Stir this mixture and consume it immediately. To use as an Epsom salt soak, dissolve in a big amount of water in a bathtub. Follow the instructions on the product packaging regarding the amount of Epsom salt to use per gallon of water.
  • Magnesium glycinate: Take this medicine with a full glass of water. Take the drug with or shortly after a meal to help your body absorb magnesium gluconate more effectively. Measure appropriately.
  • Magnesium lactate: Magnesium lactate may be taken with food if it bothers your stomach or causes diarrhea, and you should take it at the same time every day. Do not break or chew an extended-release tablet. Swallow it fully. Magnesium lactate may be only one aspect of a comprehensive therapy regimen that also involves a special diet.
  • Magnesium malate: Magnesium supplements, such as magnesium malate, are available in a variety of formats, including capsules, powders, and liquids. Magnesium malate can be taken at any time of day, with or without food, and in a single or numerous doses throughout the day.
  • Magnesium taurate: Magnesium taurate is generally taken orally once or twice a day, with or without food.

What are the side effects of Magnesium?

The most common side effects of magnesium seen in clinical trials as compared to placebo include:

Some individuals may experience serious side effects while using magnesium. These side effects may require immediate medical attention. If you experience any of the following, contact your healthcare provider or seek emergency medical help:

  • Dizziness or fainting.
  • Flushing.
  • Irritation or pain at the injection site (for intramuscular administration only).
  • Muscle paralyses.
  • Troubled breathing.
  • Rare side effects include blurred vision, coma, severe drowsiness, increased or decreased urination, and a slow heartbeat. However, this is rare in individuals with normal kidney function.

These are not all of the possible side effects of magnesium. You should always seek medical advice from your healthcare provider for any questions or concerns about your medical condition or treatment. Read all patient information, medication guides, or drug information sheets that come with this medication. You can also report adverse effects to the Food and Drug Administration at www.fda.gov/medwatch or 1-800-FDA-1088.

What are the warnings or precautions for Magnesium?

Before starting magnesium, it is crucial to discuss any existing health conditions with your healthcare provider. You should be sure that your healthcare provider is aware of all your medical conditions, including if you have:

  • Allergies.
  • Kidney disease.

Are there any contraindications with Magnesium?

  • Contraindications to consider include renal function, pregnancy, and neuromuscular disease.
  • It is critical to examine renal function before administering magnesium as renal dysfunction can reduce magnesium excretion, resulting in toxicity.
  • Patients with neuromuscular diseases, such as myasthenia gravis, should be constantly watched if administered magnesium as it suppresses the release of acetylcholine, which can lead to degeneration.

How long does it take Magnesium to work?

  • Capsules & Tablets: Magnesium pills will take a week to show any impact, but it could be longer, depending on the amount of magnesium. If you want to treat a deficiency or a disease, consuming magnesium capsules or pills for at least four weeks is the most effective strategy to ensure results.
  • Powder: This can start working after a week of magnesium intake.
  • Oil: Because oil is readily absorbed through the skin, it will typically begin to operate on specific regions within an hour of application.
  • Transdermal Sprays: These are rapid-acting since magnesium is absorbed through the skin, bypassing the digestive system.

What interacts with Magnesium?

When magnesium is taken with other prescription drugs, over-the-counter medications, vitamins, and supplements, it may change how they work or increase the frequency or severity of side effects. Make sure that you tell your healthcare professional about anything that you are taking, including:

  • Levodopa/Carbidopa (Sinemet).
  • Antibiotics (Aminoglycoside antibiotics, Quinolone antibiotics, Tetracycline antibiotics).
  • Bisphosphonates.
  • Medication for high blood pressure (calcium channel blockers)
  • Muscle relaxants.
  • Water pills (Potassium-sparing diuretics).
  • Medications that slow blood clotting (Anticoagulant / Antiplatelet drugs).
  • Digoxin (Lanoxin).
  • Medications for diabetes (Sulfonylureas).
  • Antacids.
  • Gabapentin (Neurontin).
  • Ketamine (Ketalar).
  • Proton pump inhibitors (PPIs).

What doses of Magnesium are available?

In general, the recommended daily intake of magnesium is 400 mg to 420 mg for adult males and 310 mg to 320 mg for adult females. However, this can vary if you are pregnant or breastfeeding. Talk with your healthcare provider about how much magnesium you should consume per day and which form of magnesium is best for you.

If you miss a dosage of this medication, take it right away. If it is almost time for your next dose, skip the missing dose and resume your normal dosing plan. Do not duplicate the doses. However, do not be concerned if you skip your supplement for one or more days unless otherwise prescribed by your healthcare provider.

How do I store Magnesium?

Which pharmaceutical company manufactures Magnesium?

Many companies manufacture generic or store-brand magnesium supplements.

Is there a generic version of Magnesium?

Magnesium is available as a generic.

How do I stop taking Magnesium?

Since there is no physical dependency or withdrawal associated with magnesium, you can typically stop it immediately, without tapering it.

Can Magnesium be used if I am pregnant?

It is especially important to get adequate vitamins and minerals when you first fall pregnant and to keep getting them throughout your pregnancy. However, taking high doses of dietary supplements such as magnesium during pregnancy may be dangerous to both the mother and the fetus and should be avoided.

Can Magnesium be used if I am breast feeding?

You must obtain enough vitamins and minerals so that your baby can grow appropriately. However, taking high levels of magnesium during breastfeeding can be detrimental to both the mother and the infant and should be avoided.
