What Happens If You Take Magnesium Every Day

Magnesium is a vital mineral that plays an important role in various bodily functions. If you take magnesium every day, it can have several benefits for your health.

An adult has about 25 grams of magnesium, with 50-60% stored in the bones. The rest is found in muscles, soft tissues, and fluids.

Many Americans might not get enough magnesium from their diet, but they often don’t show common signs of a deficiency. However, taking magnesium supplements or eating more foods like leafy greens, nuts, and whole grains can have numerous positive effects on your body.

However, like any supplement, it is important to understand the optimal dosage and be aware of any potential side effects or interactions with other medications. Engaging with the myriad benefits of daily magnesium intake can lead to significant improvements in overall health.

Understanding Magnesium

Magnesium is important for over 300 biochemical reactions in the body. It helps your muscles and nerves work properly and supports your immune system. Taking magnesium daily can strengthen your bones and might even boost your mood and energy levels.

If you don’t get enough magnesium, it can hurt your health and cause symptoms like muscle cramps, tiredness, and irritability.

Doctors recommend a daily intake of 350-400mg of magnesium, but this can vary based on age, gender, and overall health.

Is it Okay If I Take Magnesium Every Day?

Yes, it is generally safe to take magnesium every day, as long as you stay within the recommended dietary allowance (RDA). For adults 19–50 years, the RDA is about 400-420 mg per day for men and 310-320 mg per day for women.

Magnesium supplements can be really helpful for people with certain health issues that lower magnesium levels, like stomach problems, type 2 diabetes, or if they are taking medicines like water pills.

However, excessive intake of magnesium, especially from supplements, may cause some bad effects on health like diarrhea, nausea, and abdominal cramping. So it’s advisable to consult with a doctor before starting any supplement regimen to ensure it fits well with your overall health plan.

Benefits of Taking Magnesium Daily

Daily magnesium intake has numerous benefits for overall health, including:

1. Improved Sleep Quality

Taking magnesium every day can really improve your sleep quality. It helps regulate GABA, a neurotransmitter that calms your nervous system and sets your sleep patterns. This can reduce insomnia and help you get deeper, more restful sleep.

Plus, magnesium keeps your melatonin levels healthy, which controls your wake-sleep cycle. By getting your body ready for rest, daily magnesium can cause better sleep and overall wellness which makes you feel better during the day.

2. Enhanced Muscle and Nerve Function

Taking magnesium every day is important for your muscles and nerves to work well. Magnesium acts as a natural calcium blocker, helping muscles relax after contracting. It helps nerve impulses travel smoothly from one cell to another.

This can prevent muscle cramps, improve muscle endurance, and support overall physical performance.

3. Better Heart Health

Magnesium plays a significant role in maintaining a healthy heart. It helps regulate blood pressure by relaxing blood vessels, thereby improving blood flow. Studies have shown that adequate magnesium intake is associated with a lower risk of hypertension and heart disease.

According to the National Institutes of Health, magnesium supplementation may help reduce the risk of cardiovascular conditions like stroke and heart attack. By ensuring that you get enough magnesium every day, you can support overall cardiovascular health, making it an essential part of your daily nutritional regimen.

4. Increased Energy Levels

Magnesium is a powerhouse for your body’s energy production. It’s key in the activation of adenosine triphosphate (ATP), the molecule that transports energy within cells. Without sufficient magnesium, the efficiency of ATP production decreases, leading to lower energy levels and increased fatigue.

5. Improved Digestion

Magnesium is important for a healthy digestive system. It helps balance stomach acid and makes it easier to pass stool which, lowering the chance of constipation. Magnesium helps ensure regular bowel movements by drawing water into the intestines and softening the stool.

This can relieve common digestive issues and contribute to overall gut health. For those struggling with chronic digestive problems, a daily magnesium supplement can provide much-needed relief and improve digestive regularity.

6. Stronger Bones

Magnesium is important for strong bones. It helps build and keep bones healthy by activating vitamin D in the kidneys, which helps your body absorb calcium.

Getting enough magnesium every day can help make your bones stronger and lower the chance of osteoporosis, especially as you get older. It keeps your bones healthy and reduces the chance of breaks and other bone problems.

Possible Side Effects of Daily Magnesium Intake

Magnesium is usually safe, but having too much can be bad for your health. Some side effects of taking too much magnesium might be:

  • Diarrhea: Overconsumption of magnesium supplements can lead to digestive issues, including diarrhea.
  • Nausea and Vomiting: Taking high doses of magnesium may cause nausea or vomiting.
  • Abdominal Cramping: Excessive intake can result in stomach cramps and discomfort.
  • Medication Interactions: Magnesium can interact with certain medications, such as antibiotics and blood pressure medication, reducing their effectiveness.
  • Fluctuation in Blood Pressure: In extremely high doses, magnesium can cause irregularities in blood pressure levels.
  • Kidney Issues: Those with kidney problems should be cautious, as excess magnesium can accumulate and cause harm.

Who Should Not Take Magnesium?

Magnesium is good for many people, but some should be careful or avoid it. Here are some groups who must not take magnesium without a doctor’s advice:

  • People with Kidney Disease:
  • Those suffering from kidney conditions, especially chronic kidney disease, should be cautious. Kidneys help regulate magnesium levels, and impaired kidney function can cause magnesium accumulation, potentially resulting in toxicity.
  • Individuals on Certain Medications:
  • Some medications may interact negatively with magnesium supplements, such as:
    • Antibiotics: Magnesium can reduce the effectiveness of certain antibiotics, like tetracycline and ciprofloxacin.
    • Diuretics: Also known as water pills, these can alter magnesium levels in the body.
    • Blood Pressure Medication: Magnesium can interact with medications used to control high blood pressure, potentially causing unwanted effects.
  • Pregnant and Breastfeeding Women:
  • While moderate magnesium intake is generally safe, pregnant or breastfeeding women should consult their provider before taking supplements to avoid any potential risks to both mother and child.
  • People with Heart Block:
  • Magnesium affects the electrical impulses in the heart. Those diagnosed with heart block should avoid magnesium supplements unless advised by a healthcare provider.
  • Older Adults:
  • As kidney function can decrease with age, older adults might build up too much magnesium. They should talk to a healthcare provider before taking supplements.
  • Individuals with Gastrointestinal Disorders:
  • Conditions like Crohn’s disease or inflammatory bowel disease (IBD) can affect magnesium absorption. Supplementation should be carefully monitored to avoid complications.
  • People with a History of Allergic Reactions to Magnesium:
  • Those who have experienced an allergic reaction to magnesium supplements in the past should avoid taking them without medical advice.

What’s the Recommended Daily Dosage of Magnesium?

The Recommended Dietary Allowance (RDA) for magnesium varies by age, sex, and life stage. For adults, the RDA is typically between 310-420 mg per day.

The FDA created DVs to help people compare the nutrients in foods and supplements in their overall diet. For magnesium, the DV is 420 mg for anyone 4 years and older.

According to NIH, Food labels don’t have to list magnesium unless it’s added to the food. Foods with 20% or more of the DV are high in that nutrient, but even foods with lower percentages can still be part of a healthy diet.

It’s best to obtain magnesium from a balanced diet rich in green leafy vegetables, nuts, seeds, and whole grains.

If supplementing, it’s crucial not to exceed the upper limit of 350 mg per day unless advised by a healthcare provider.


Magnesium is important for many body functions, like making energy, keeping bones healthy, aiding digestion, and supporting the heart. While it has many health benefits, it’s crucial to stick to recommended amounts and watch for possible side effects.

Always talk to a doctor before starting any supplements, especially if you have health issues or take other medicines. Eating a balanced diet with foods rich in magnesium is the best way to meet daily needs and stay healthy.


Can I overdose on magnesium from food sources alone?

No, it’s highly unlikely to overdose on magnesium from food sources alone. The kidneys efficiently eliminate excess magnesium obtained from dietary sources. However, excessive intake from supplements or medications can lead to toxicity.

Can magnesium supplements cause diarrhea?

Yes, magnesium supplements can cause diarrhea, especially when taken in high doses. This is one of the most common side effects of excessive magnesium intake and occurs because magnesium has a laxative effect on the digestive system. To avoid this, stick to the recommended dosage that is right for your age and health status.

Is it safe for pregnant women to take magnesium supplements?

Yes, it can be safe for pregnant women to take magnesium supplements, but they should consult their healthcare provider first. Having the right amount of magnesium is important during pregnancy, but taking too much can be harmful for both mom and baby. Always listen to your doctor to stay safe.
