Does your child actually need supplements?

The kids’ supplement market has exploded in recent years. There are probiotics, magnesium powders, greens gummies, and even full supplement routines designed specifically for toddlers. Few of these things were on the shelves when we were growing up, which makes you wonder: do children actually need all of this?

As a mother, I know how easy it is to want to give your child every possible advantage, especially when it comes to their health. But the supplement aisle is overwhelming, the marketing is loud, and the advice on social media often contradicts what you hear from your pediatrician. It can be hard to tell which supplements are genuinely useful and which are mostly good marketing in kid-friendly packaging.

The better place to start is not with the supplement. It’s with the child. Before adding anything new, I usually begin with three basic questions:

- Are they eating a balanced diet that includes fruits, vegetables, protein, whole grains, and healthy fats?

- Are they sleeping through the night?

- Are they having healthy, regular bowel movements?

The answers tell you far more about what your child may actually need than any label on the shelf. They also make it much easier to tell which supplements are worth considering. Here are a few I recommend most often in my practice:

Multivitamins help ensure children get adequate amounts of key nutrients throughout their growing years. A multivitamin does not replace real food, but it can help fill in the gaps when a child’s diet narrows. That is especially useful during phases of selective eating, restricted diets, or long stretches when a child seems to be surviving on little more than crackers and berries.

- Children born via C-section. During vaginal delivery, babies are introduced to maternal microbes that begin colonizing the gut. Babies born via C-section miss this initial exposure, which is why they need to be supplemented from birth.

- Children who were formula-fed ONLY. Breast milk helps nourish and shape the developing microbiome in ways formula does not fully replicate.

- Children who’ve had repeated courses of antibiotics. Antibiotics are often necessary, but they do not distinguish between harmful bacteria and beneficial bacteria. Even one course can disrupt the gut microbiome, and repeated courses can make it harder to rebuild.

- Children who are always sick. Healthy bacteria play a significant role in immunity against bad bacteria and viruses. Building a durable gut microbiome also builds resilient immunity.

- Children with frequent digestive issues. Kids with chronic constipation, irregular stools, or recurring stomach issues may also benefit from probiotic support, though persistent symptoms warrant a closer look.

That is not exactly what they are. Greens gummies do not replicate the full nutritional value of actual produce, but many do offer fiber and prebiotics in a form kids will take. This can be useful during long stretches when vegetables are off the table and fiber intake is low, especially if constipation is part of the picture. I wouldn't call them essential, but they can fill a gap when getting actual vegetables into your child feels impossible.

There's no one-size-fits-all supplement routine for kids. What makes sense for one child may be unnecessary for another, depending on how they were born and fed, what they actually eat, and whether other factors, such as a frequent antibiotic use, GI issues, or conditions like ADHD or ARFID, are affecting appetite, digestion, or absorption.

And just as importantly, the right supplement is the one your child will actually take. Some kids chew a gummy without thinking twice; others refuse chewables but will drink a powder in juice; others melt down at the sight of a dropper. Format matters. The right supplement is the one they'll take consistently without a daily fight.

The best place to start is with your child. Let’s focus on what they actually need, what may not be necessary, and what might be better supported through good nutrition and sleep.
