Supplements and children: What parents should know
5/14/2026 by Amanda Hargett-Granato, D.O.
Every parent wants to provide the best possible support for their growing child’s mind and body. Vitamins, herbal products and other dietary supplements often market themselves as safe and natural ways to improve health, but that does not always mean that they’re appropriate for children.
Compared to prescription medications, supplements are much less strictly regulated. This means safety, quality and effectiveness are not guaranteed to the same extent as with prescription medications. The amounts of active ingredients may vary from bottle to bottle, and some products may contain ingredients not listed on the label.
As children grow, their bodies have different needs than those of adults. Doses of supplements that may be safe for adults can be too high for children. Getting too much of some vitamins — such as vitamin A or iron — can actually be harmful to kids.
Just because a supplement says it is natural does not mean that it is safe for everyone. Herbs contain active chemicals that can cause side effects or interact with medications. Most of these supplements have not been tested in children, so safe doses are often not known.
There are some situations where supplements play an important role, like vitamin D in infants or iron in some cases. However, if your child eats a balanced diet, they are likely getting all the nutrients they need to grow and develop from their food.
If you are concerned that your child is missing something in their regular diet, it is important to talk with your child’s pediatrician first. They can help determine what might be needed, provide recommendations for safe options and ensure the correct dose is given.
Supplements can be helpful in specific situations, but they are not risk-free. Healthy habits like balanced meals, regular physical activity, sleep and routine medical care, are the most important building blocks for your child’s well-being. When in doubt, ask your child’s pediatrician before giving your child any new product.
