Side Effects of Taking Too Much Magnesium: Signs & Risks
The human body requires magnesium to operate hundreds of essential functions, which include muscle contractions, nerve signaling, and energy production (1).
Multitudes of individuals choose magnesium supplements because they want better sleep and want to manage both stress and reduce the risk of heart issues.
Emphasizing that large supplemental magnesium intake produces adverse reactions,s which become more pronounced with excessive doses (2).
Your body will normally regulate magnesium intake from food sources, including leafy greens, nuts, and seeds, but taking excess supplements causes mineral toxicity because your body cannot manage this amount.
Anyone using magnesium supplements needs to be aware of the maximum safe intake along with possible health risks.
What Happens When You Take Too Much Magnesium?
Your body controls its magnesium levels through the kidneys by eliminating extra amounts through your urine.
The body absorbs excess magnesium mainly from supplements which accumulates in your system leading to digestive distress before attacking vital systems in cases of severe toxicity.
Most dietary magnesium enters the body without causing any damage because your body will naturally remove any excess nutrients.
Supplements bypass natural regulation; therefore, they can trigger various health issues when taken in large doses.
People who have problems with their kidneys face higher magnesium risk because their body fails to efficiently remove surplus magnesium from their system.
Symptoms of Too Much Magnesium
Your body will trigger digestive problems when it tries to eliminate excess magnesium which results from a mild overdose.
Common mild symptoms include:
-
Diarrhea
-
Nausea
-
Stomach cramps
-
Bloating
An excessive intake of magnesium through products such as magnesium citrate and magnesium oxide leads to diarrhea, which is one of the initial symptoms.
Extreme overconsumption of magnesium leads to the appearance of serious clinical manifestations.
Severe symptoms of magnesium toxicity include:
-
Low blood pressure (hypotension)
-
Irregular heartbeat (arrhythmia)
-
Muscle weakness
-
Lethargy
-
Confusion
-
Difficulty breathing
Very high magnesium amounts in the bloodstream, known as hypermagnesemia, result in coma or heart failure, primarily among people with kidney limitations (3).
How Much Magnesium Is Too Much?
People of different ages, coupled with their gender and their lifestyle, determine how much magnesium they should consume each day.
Daily Magnesium Recommendations:
-
Men (19-30 years): 400 mg
-
Men (31+ years): 420 mg
-
Women (19-30 years): 310 mg
-
Women (31+ years): 320 mg
-
Pregnant women: 350-360 mg
A diet that contains vegetables and almonds with avocados enables most people to obtain sufficient magnesium without requiring supplements.
Users of magnesium supplements need to exercise caution when receiving daily dosage because the upper tolerable limit stands at 350 mg per day from dietary supplements (4).
Medical specialists may authorize higher doses occasionally, but these prescriptions can only be made with direct doctor supervision.
Magnesium Overdose: When to Be Concerned
Mild magnesium overdose will heal itself when the body eliminates the excess magnesium through the digestive tract.
Dangerously high magnesium levels can result in severe toxicity,y which becomes most dangerous when patients have kidney problems or over-supplement with magnesium liquor over long periods of time.
Quick medical help should be sought in cases where these signs become noticeable:
-
Extreme drowsiness or confusion
-
Weakness or loss of muscle control
-
Severe nausea and vomiting
-
Slow or irregular heartbeat
-
Difficulty breathing
Doctors use IV calcium gluconate for treatment in medical emergencies to counter magnesium effects and hospitalize patients for dialysis to extract blood magnesium (5).
How to Remove Excess Magnesium from the Body
When you suspect you have consumed too much magnesium, the first action must be to stop taking supplements.
Naturally, getting rid of excess magnesiuinor your body requires these steps:
-
Drinking water in abundant amounts helps your kidneys function properly while the body uses urine for magnesium elimination.
-
Food consumption of high-fiber products advocates magnesium absorption in the digestive tract, thereby speeding up elimination.
-
Nuts, seeds, and dark chocolate should be avoided as high-magnesium foods when experiencing symptoms of excess.
-
You should seek medical advice for ongoing severe symptoms of magnesium overload.
The treatment of excessive magnesium in patients with renal problems usually consists of medical procedures including dialysis.
Safe Magnesium Supplementation: How to Get It Right
Acquiring magnesium supplements requires selecting the proper forms and dosage amounts.
A person may experience stomach upset from magnesium citrate and magnesium oxide supplements, whereas magnesium glycinate tends to produce fewer unwanted digestive reactions.
Here are steps you should follow to prevent taking excessive amounts of magnesium:
-
Follow the dosage instructions written on supplement labels for your consumption.
-
Food sources should serve as your primary choice when selecting magnesium.
-
A doctor needs to evaluate high-dose magnesium use, particularly for people with kidney disease or different medical issues
The natural sources of magnesium include various leafy greens, banana pumpkin seeds, and salmon fish.
Final Thoughts
No substance or element in the world should be taken beyond its desired amount so as to remain beneficial for the body.
Taking excessive magnesium supplements tends to cause digestive problems alongside blood pressure drops, which sometimes result in serious heart inconveniences.
Protect your safety by following daily dosage limits, and then make food choices with high magnesium content while becoming aware of its overdose symptoms.
Select a sustainable magnesium supplement that also offers good absorption by your body.
The benefits of health depend on maintaining equilibrium between everything; g and magnesium follow a similar pattern.
