You’ve heard the saying “everything in moderation” I assume. This may be some of the best advice that is consistently given. While a magnesium overdose is possible, it is something that rarely happens and something I would not worry about myself. This is a question that comes up often. A lot of people wonder how much magnesium is too much magnesium. Magnesium toxicity is a concern for some. I felt it was time to explore the symptoms of a magnesium overdose. Personally, I take 500 mg of magnesium a day. I have been using JigSaw Magnesium w/SRT for a while and have been pretty happy with the results. SRT is a propriety technology that stand for “sustained release technology.” Basically it releases the magnesium into your body slowly, over time.
So what causes a magnesium overdose?
It is unlikely that you would overdose from eating magnesium rich foods. Even if you went on a lentil and kale bender, it’s not likely. Magnesium overdoses generally occur as a result of magnesium supplement abuse or mismanagement. Perhaps taking too many pills in a short period of time could cause a magnesium overdose. Drinking magnesium oil with no regard for quantities may be another reason someone would suffer from symptoms of too much magnesium. These are the types of behaviors that can lead to a magnesium overdose.
Magnesium overdose or hypermagnesemia, is when abnormally high levels of magnesium occur. Even with supplement mismanagement this is a rare condition. The kidneys are extremely effective and efficient at removing excess magnesium from the body. Care should be taken. A combination of under performing kidneys and excess magnesium intake can cause dangerous magnesium toxicity.
In the instance of a magnesium overdose you more than likely will experience diarrhea. You may experience weakness or vomiting. Impaired breathing is possible and you may notice decreased respiration. Dehydration is a legitimate concern in case of a magnesium overdose. Diarrhea combined with vomiting can drain the body of necessary fluids rather quickly. Dehydration can lead to other problems as well. Other biochemical reactions have a much harder time performing properly when the body is not properly hydrated. Hypercalcemia is often associated with hypermagnesemia. Symptoms of severe hypercalcemia can include nausea and vomiting, constipation, abdominal pain, lethargy, muscle aches, and confusion. Ultimately a magnesium overdose is not something I concern myself with. Of course I must recommend that you consult your doctor before taking any magnesium supplements.
How much magnesium should I take?
It is my opinion that without blatant disregard for recommended daily magnesium dosage you should not see any side effects of too much magnesium. As I mentioned earlier, I take 500 mg of magnesium daily in supplement form. This is on top the magnesium I receive from magnesium rich foods. I do not plan on taking any more than 500 mg in a day. This is not a “more is better” situation. This is the level that works for me. When I started taking a daily magnesium supplement in the beginning of 2013 I started slow. I took 200 mg daily and worked my way up to my current levels. If you decide to begin taking a daily magnesium supplement start by reading the reviews. All have pros and cons and of course some are better than others.
