Best magnesium supplements for kids: product reviews

Now, let's turn our attention to a select few children's magnesium supplements that stood out the most in our research.

1. Dr. Moritz — best magnesium supplement for kids overall

Dr. Moritz Kids Magnesium Gummies

Magnesium gummies by Dr. Moritz are formulated to support muscle and nerve function, maintain bone health, and bring a sense of calm. But what gets them our nod as the best magnesium for kids is their safety profile.

Besides being entirely sugar-free, these magnesium gummies are also free of major allergens, including dairy, gluten, eggs, nuts, fish, and soy, according to the makers. Plus, they contain chicory root, a valuable source of fiber, which may have positive benefits on your child’s digestive system.

Each daily single gummy serving of this children’s magnesium is set to deliver 100 mg of magnesium citrate.

While the manufacturer notes that this dose may be suitable for children ages 2 and above, Dr. Moritz's magnesium gummies should not be consumed by children under 4 years old. This is with reference to the RDAs of magnesium.

A one-time purchase of Dr. Moritz's bottle containing 60 raspberry-flavored gummies will cost you $14.99. You may consider buying a 2-pack or opting for the brand’s ‘subscribe and save’ model for additional savings.

2. Natural Vitality — best children’s magnesium for a calming effect

Natural Vitality Calm Kids Magnesium Gummies

Funnily labeled 'CALM Kids,' Natural Vitality's magnesium gummies are infused with highly bioavailable magnesium citrate and are formulated to support a healthier response to stress.

CALM Kids gummies provide 83 mg of magnesium citrate in a single gummy serving. Given the amount, this supplement should not be taken by children under the age of 4.

What we appreciate about Natural Vitality are the clear indications of which age group should consume these gummies and which should avoid them. Instead of being concealed, this information is prominently featured throughout the brand's page — this transparency adds a level of trust.

A 120-count bottle of Natural Vitality’s magnesium gummies is currently available for the price of $23.49.

3. Zahler — best magnesium for kids in multiple flavor options

Zahler Chapter One Magnesium Gummies kids

Zahler's magnesium gummies provide a refreshing twist in the predominantly raspberry-flavored gummy market. If your child has a specific taste preference, these gummies, available in apple, peach, and, of course, raspberry flavors, might be an excellent choice to help maintain their optimal magnesium levels.

Each of Zahler's gummies contains 50 mg of magnesium citrate. While this amount is generally regarded as safe for most children, the recommended serving size provided by the brand is 2 gummies, totaling 100 mg of magnesium — an amount not suitable for children under the age of 4.

Per the brand, all of its products, including these magnesium gummies, are produced and bottled in a GMP-compliant facility in the U.S.

As for the price, while the raspberry-flavored gummies are priced at $13.46, the cost may vary slightly depending on the flavor of your choice. Zahler's magnesium gummies are currently available on Amazon.

These gummies are free from added sugar and made without any artificial flavors and colors. They are also non-GMO, gluten-free, and vegan-friendly.

While the product label suggests that this supplement is suitable for children aged 2 and above, it can be misleading. Each gummy serving delivers 100 mg of magnesium, an amount appropriate only for children over the age of 4, as recommended by the NIH guidelines.

A bottle with 30 raspberry-flavored gummy pieces, enough to last your child a month, is currently available on Amazon for the price of $9.99.

While supplement gummies can offer a convenient way to support your child’s health, it is important to recognize that they contain active ingredients. Therefore, it is important to ensure that the recommended serving size is followed and such supplements are kept out of reach of children, as they may mistake them for candy. It is crucial to consult with a healthcare professional before incorporating gummy supplements into your child’s routine, particularly if they have underlying health conditions or are taking any other supplements or medications.

How much magnesium do children need?

Making sure that your child meets magnesium needs during their developmental stage is essential for several reasons, including strengthening bone and teeth health, supporting nerve and muscle function, and promoting quality sleep. But what is just as much of the essence here is the correct amount of magnesium that should be given to your child.

See, magnesium intake from dietary sources and from supplements is not exactly the same. The magnesium from natural food sources is generally well-tolerated and does not pose a risk of toxicity, as the body can efficiently regulate magnesium absorption from food, with excess amounts being excreted through urine.

On the flip side, excessive amounts of magnesium from supplements can lead to side effects such as diarrhea, nausea, and even abdominal cramping. For this reason, it is important to stay within the recommended levels, which actually vary depending on age.

Here’s a breakdown of the RDAs for children of different age groups:

AgeRecommended magnesium amount
From birth to 6 months30 mg
Infants from 7 to 12 months 75 mg
Children from 1 to 3 years80 mg
Children from 4 to 8 years 130 mg
Children from 9 to 13 years 240 mg

How to choose the best magnesium for children

Consider using our recommended buyer’s guide as a roadmap for your next magnesium supplement purchase for your child. Here’s what you need to know:

  • Magnesium form. Given that each magnesium form has unique characteristics, the choice may depend on your child's needs and preferences. But in any case, you should prioritize well-absorbed and well-tolerated forms.
  • Type of supplement. The taste aspect is crucial for compliance, especially for picky eaters. Aim for a type that your child enjoys, like that of gummies, to make the supplementation process more enjoyable.
  • Consider your child’s allergies. If your child has known allergies or sensitivities, it is important you go over the supplement’s ingredients list to make sure the formulation is allergen-free.
  • Check in with a pediatrician. Before introducing any new supplement to your child, seek advice from a healthcare professional. They will help you ensure the chosen magnesium form and dosage are appropriate.

Could children experience side effects from magnesium supplements?

You might be wondering if magnesium is safe for kids. This is likely to be one of the initial considerations for someone who is considering introducing a magnesium supplement to their child’s diet. Although magnesium is essential for the normal growth and functioning of children, supplements can still lead to side effects.

Some potential side effects that are reported when supplementing with children’s magnesium include diarrhea. This side effect is linked to excessive magnesium intake and is a rather common occurrence. Additionally, some children may experience nausea and abdominal cramping, particularly if magnesium supplements are taken on an empty stomach or, again, in excessive doses.

On rare occasions, allergic reactions may occur, as children can be allergic to specific forms or additives in magnesium supplements.

To minimize the potential of these side effects, it's imperative that you base your decision when considering magnesium supplements for your child in consultation with a pediatrician. They can assess the child's individual health status, conduct necessary tests to determine magnesium levels, and provide personalized recommendations based on the specific needs of the child.

The best magnesium form for kids

When it comes to the best magnesium supplements for kids and the form in which they come in, there may not be a single solution that fits all. Each form of magnesium may offer slightly unique benefits, and while one may appear more advantageous than the other, the optimal choice in the end depends on the child’s specific needs. These needs are often influenced by factors such as tolerability and specific health concerns.

To help you better understand what may or may not be suitable for your specific case, we provide a detailed comparison of common forms of magnesium below. These are often encountered when searching for children’s magnesium supplements.
