Does your child often feel tired or lethargic? Does he complain about muscle cramps, pain or sleeplessness? If yes, then he may not be having the required amount of magnesium in his body.
Magnesium is one of the most abundant micro-minerals in the human body. Magnesium for kids is essential as it supports the functions of hundreds of enzymes, promoting healthy bone development. Without this mineral, your child may not thrive as well as he should during the growing years. In this article, MomJunction tells you everything you need to know about magnesium and how important it is for kids.
Why Is Magnesium Important For Kids?
Magnesium is a mineral that supports several functions in the body, including nerve function. It:
- helps transmit nerve signals.
- helps control blood sugar levels.
- supports protein synthesis.
- helps regulate blood pressure .
- Aids in the production of energy that the body needs.
- strengthens bones – a study by the Pediatric Academic Societies has revealed that magnesium is just as important as calcium for bone health. (1)
- plays a vital role in carrying calcium and potassium to the membranes in the body – this is important to control muscle contractions, maintain a healthy heart rhythm and nerve impulse conduction.

Recommended Magnesium Dosage For Children
The recommended daily intake (RDI) of magnesium as defined by the US Food and Nutrition Board (FNB) is:
- Kids aged one to three years – 80mg
- Kids aged four to eight years – 130mg
- Kids aged nine to 13 years – 240mg
- Teens aged 14 to 18 years – 360mg for girls, 410mg for boys
Magnesium is abundantly present in our bones and soft tissues. It is there in our blood serum but in meager quantities. Intake of magnesium rich foods is essential to regulate the amount of the mineral present in our body. It should be enough to support bone development and also carry out other functions normally.

An average American kid’s meal does not provide the required amount of magnesium to his body.

Are Magnesium Supplements Safe for Kids?
Magnesium supplements can have side effects, which is why you should consult a physician before you decide to give them to your kids. Make sure that the supplements are taken as prescribed by the doctor. Magnesium supplements are available on prescription as well as over the counter. The doctor may recommend prescription medicines when the child has a severe magnesium deficiency. Over- the-counter medications are usually multi-vitamin and mineral blends. Having the right dose is important as taking more than the limit is not advisable.
In fact, excess magnesium for children can lead to nausea, irregular heartbeat, respiratory distress, lethargy, facial flushing, diarrhea, stomach cramps, vomiting, muscle weakness, low blood pressure, and urine retention. Avoid choosing supplements which have magnesium in the form of magnesium oxide, magnesium sulfate and magnesium aspartate and glutamate. Magnesium oxide is hard to absorb and can even cause diarrhea, while it is easier to overdose on magnesium sulfate. The best forms of magnesium are magnesium citrate and magnesium oil for kids, which are used topically.
Medical conditions and allergies: Patients with renal conditions are at high risk for magnesium overdose and therefore should not take any supplement unless discussed with their doctor, due to the possible decrease of magnesium excretion in the urine. Children with chronic abdominal conditions also need to first get medical guidance before taking supplements. Those with endocrine disorders are also at higher risk.
Patients must be careful not to take multiple medicines or supplements that contain magnesium as it all adds up. Some parents like to take numerous supplements and immune boosters together, and ingredients might overlap and cause overdose.
Remember that the best sources of vitamins and minerals are always the natural ones – fruits and vegetables. You should consider supplements only if your child is not getting the right amounts of minerals from his diet. Supplements should not be used as a replacement for natural sources of magnesium.
Hypomagnesemia is associated with insulin resistance, hypertension, metabolic syndrome, migraine and asthma. Magnesium deficiency can lead to neuromuscular irritability that is presenting with tremors, fasciculations, muscle weakness, convulsions and apathy. It can also cause some changes with the electrical transmission of the heart and is seen as changes on an ECG.
Fatigue is a common problem with children having a magnesium deficiency. Insomnia is also an issue that growing children with the deficiency will have to deal with. Lack of magnesium prevents the child’s body from growing to its fullest potential. The sooner you deal with magnesium deficiency in your kid, the better it is for their overall development.
Detecting Magnesium Deficiency In Children
So, how would you know if your child is low in magnesium? Neglecting the early symptoms could lead to a more serious problem. Therefore, check if he has such signs. Symptoms that indicate magnesium deficiency can be physical, neurological, cardiovascular or muscular, such as.
