Calcium Supplements for Kids – Safe Natural Calcium for Children

Child Taking Supplement from Parent

If it were up to most kids, it’d be hot dogs, french fries, and sugar all day. But as a caring parent or grandparent, you wouldn’t let the kids have their way for every meal!

After all, chances are the kids wouldn’t get all the essential nutrients they need for proper development. And one of those nutrients is of course, calcium. Children need calcium for strong bones and teeth. And as you’ll see below, the benefits go much deeper than that!

So whether you’ve got a picky eater on your hands, a lactose intolerant child, or any other “food challenged” child, it’s even more important you ensure the child gets enough calcium. Plus, you’ll also find your answer to the question, “Does my child need a calcium supplement?”

How Much Calcium Does My Child Need?

According to the USDA’s Continuing Survey of Food Intakes of Individuals, there’s a startling calcium-deficiency sweeping the nation. And it looks like our children and grandchildren have it the worst. Here are the percentage of calcium-deficient children in each age group:

  • 44% of boys and 58% of girls ages 6-11
  • 64% of boys and 87% of girls ages 12-19

These figures caused the US Surgeon General to say the absence of adequate nutrition during these critical bone-building years has placed America’s bone health in jeopardy.

And the Surgeon General goes on to recommend calcium and vitamin D supplementation for children, adolescents, and adults.

And if you know anything about osteoporosis, this is especially true. After all, clinical studies show a leading cause of osteoporosis is lack of proper nutrition. In fact, it’s been said that osteoporosis is a “geriatric disease with pediatric origins”. And studies show if you can build strong bones throughout childhood and adolescence, bone loss in later years will have less effect.

So, here’s how much calcium children need at each age group, according to a public health report from the Institute of Medicine:

Recommended Daily Intake Of Calcium
Male and Female Age (years)Calcium (mg/day)
1 – 3700
4 – 81,000
9 – 131,300
14 – 181,300

What happens if a child does not get enough calcium?

A calcium deficiency can cause a whole host of problems in children. Of course, a calcium-deficient child’s bones won’t maintain their density like a healthy child’s would. And a lack of calcium and vitamin D can lead to rickets, a condition where children have soft, weak bones.

After enough years of decreasing bone density, the child will eventually lose enough bone minerals to make them osteoporotic in adulthood. And with osteoporosis, comes elevated risk of fractures.

But there are more concerns beyond just bone health. That’s because a calcium deficiency can also stunt a child’s growth. What’s more, some studies show a calcium deficiency can impact a child’s ability to learn. Still others link calcium intake to preventing obesity, insulin resistance, kidney stones, high blood pressure, and more.

And a calcium deficiency can also upset the immune system. After all, calcium is a key mineral in our immune response to foreign invaders, and recent research shows it’s even the “first responder” in tissue damage.

It’s little wonder why a calcium deficiency can cause so many health problems, seeing as calcium is the most abundant mineral in the body!

Now, well-nourished children can get good amounts of calcium from their diet. And they can get it from both plant and animal sources. (To help on that front, visit our Top Calcium-Rich Foods post here.)  

But again, if you’ve got a picky eater, lactose-intolerant, or milk allergy child to worry about, you might have to consider adding more calcium to their diet. And that’s where a proper, body-friendly calcium supplement comes in.

5 Things to Look for in a Kid’s Calcium Supplement

Organic, Non-GMO, Dairy-Free

When you can control the purity of your supplements, you should do so. And that’s no different for a child. So if you can ensure your child’s calcium is free of pesticides, toxins, and other foreign matter, so much the better. So go organic when you can.

Same with non-GMO products. As you may know, GMO stands for “genetically modified organism” which means the organism (in this case, food) had its DNA changed in a lab. So while the jury’s still out on GMO products, it’s best to avoid them and be safe rather than sorry.  

Finally, if your child is lactose intolerant or has a milk allergy, it goes without saying that they need to avoid dairy and should look for a dairy-free calcium source.


Our little ones have sensitive, developing digestive systems. So it’s always best to remember “the gentler, the better”. Unfortunately, most calcium supplements (like calcium carbonate and citrate) are rock-based. And rock-based calcium can often disrupt even the heartiest digestive system— leading to constipation, bloating and an upset stomach in all ages!

So look for plant-based calcium instead. Plant-based calcium ensures your child gets their calcium from a whole food, which their whole body will appreciate!

Easy to Take

Most children aren’t exactly thrilled with swallowing pills. And most physically can’t, or shouldn’t. So look for calcium that comes in a powder, gummy or another form rather than a large capsule.

More than just a calcium supplement

It may sound odd, but when you’re choosing a calcium supplement for a child, choose one that’s more than just calcium! For example, you’ve probably heard how vitamin D helps with calcium absorption, blood calcium levels, and therefore bone formation. And you learned above how a vitamin D deficiency can lead to rickets in children.

Next, you’ve probably heard magnesium also works with calcium to build strong bone and reduce the rate at which bone wears down. But you may not have heard the importance of trace minerals to healthy bones.

Your bones are made up of more than just calcium and magnesium. In fact, there are dozens of minerals in your bones. But there are a few trace minerals in particular that are proven to help increase bone density at any age!

So where you can, see that you get as many of the following as possible along with calcium and magnesium: phosphorus, boron, copper, manganese, potassium, nickel, vanadium, zinc, silica, selenium, and strontium.

Safe, Effective and Clinically proven

If you can get all four of the previous things in a child’s calcium supplement, that’s great. But if you can get a calcium that’s clinically proven to be effective at building bone, that’s the “holy grail”.

After all, you won’t see any calcium supplement companies investing tens of thousands of dollars in studies to prove their calcium improves bone health. And no company “owns” calcium-rich foods, so that’s why you don’t see a single food or calcium supplement actually guarantee you improved bone health. Except one… AlgaeCal.

AlgaeCal actually did invest the time and money to have our natural calcium AlgaeCal Basic put to the test in a real human study. And that study proved what no other calcium ever has: an organic, plant-based, easy-to-take calcium built new bone in adult participants— without side effects.
