Kids Need Magnesium Too! Here’s What You Need To Know.

Magnesium and kids

Does your child need more magnesium?

The first question to ask is, are they getting any through diet? Do they eat a lot of legumes, seeds and leafy greens? Mackerel, perhaps?

Not likely, and that’s why most children aren’t getting enough magnesium. ‘Kid foods’ like pizza, pasta, toast and cereal are woefully inadequate when it comes to what may be the most important nutrient for total health.

Why is magnesium so important for kids?


First, magnesium is absolutely essential for coping with stress. Our very cells need magnesium to downgrade the instinctive stress response, and to reinstate calm.

And have no doubt, stress is an intrinsic part of childhood.

The very act of growing is a stressor. It places huge demands on the body, which requires more energy and rest to repair. At the same time, growth triggers shifts in hormones, all of which can be experienced as a continuous state of flux.

In fact, the physical stress of growing up may well be overshadowed by the emotional and mental stressors.

A day in the life of childhood is fraught with drama. They’re immersed in a highly interactive, highly dynamic environment with other little people who are just learning to be sensitive and kind. Just think: when was the last time you had to hang out with friends who bit, shoved, or called you names? Right. But our kids face it every day.

Add to that, a child’s world is full of the unknown, triggering outsized fears.

Remember nightmares? There’s a reason kids have more nightmares than adults: their developing minds are constantly processing a world of unknowns, which to the brain appear as threats.

So, routine physical stress and emotional stress place serious demands on childrens’ magnesium stores.


Equally important, magnesium plays a vital role in healthy growth and development.

That’s because magnesium is a co-factor for an estimated 700-800 enzyme systems throughout the body. It may well be the hardest-working nutrient of all!

What does this mean in practical terms?

Kids need magnesium for:


Children exhibit many of the magnesium deficiency symptoms that we see in adults, but not all. The most common include:

  • Constipation
  • Poor sleep
  • Irritability
  • Fatigue
  • Cramps
  • Twitches and tics
  • Headaches and migraines

It’s important to note too that attention deficit hyperactivity disorder (ADHD), and childhood depression are associated with magnesium deficiency (The Magnesium Miracle, Kindle version page 1854).

According to Dr. Dean, it’s possible these conditions are caused by magnesium deficiency (p. 1855). We can’t be sure, but we do know that magnesium is essential for children’s physical, emotional and mental well-being.


Some children may need more magnesium.

“Dr. Leo Galland, author of Superimmunity for Kids, speculates that hyperactive children need extra magnesium due to their constantly high adrenaline levels.” For these children, Dr. Galland recommends 6 mg per pound of weight per day. (The Magnesium Miracle, Kindle version page 1872).

A forty pound child would thus need 240 mg of magnesium per day. That equates to about 10 cups of raw spinach, 1.5 cups of cooked spinach, ¼ to ½ cup of seeds/nuts, or 8 oz. of a fish like mackerel.

To supplement their diets, Dr. Leo expressly recommends magnesium citrate – the kind we use in Natural Calm – in a dose of 1 tsp to 1 tbsp per day.

As always, we echo Dr. Carolyn Dean in advising that you dole out the dose incrementally throughout the day. Avoid offering a child their full dose at one time – mainly because of the laxative effect, but also because you’ll see better results in addressing symptoms of deficiency.


What might this look like? You might offer your child a warm cup in the morning and evening, or you might dissolve their total dose in hot water and then add it to a bottle of cold water, to sip throughout the day.

Note that we offer Natural Calm as Kids Calm. It’s the same formula as Natural Calm for adults but includes easy-to-follow dosing, by age, for kids from 1 to 18. Parents will love that we’ve kept it sugar-free and organic, available in our most popular Raspberry-Lemon flavour. Look for the 4 oz bottle at your local retailer, or from our online store for $22.31, and as always, shipping is free within Canada.
