The decision to add supplements to your kids' routine is a personal one and one that should be made with a trusted healthcare provider. All kids' needs are different, and a supplement that is beneficial for one kiddo may not offer the same benefits for another kiddo.

Therefore, your first step should be to work with a healthcare provider to determine what kind of supplement, if any, would be helpful for a particular health challenge. Once that is determined, you are ready to head to the store or start searching online. 

No matter which type of supplement you are looking for, there are some common things you should check for when choosing one for a kiddo. Keep reading to find out more. 

Age-Appropriate Formula

Keep in mind kids are not just small adults and their nutritional needs differ depending on their age. Choosing an age-appropriate formula helps to ensure your kiddo is getting a supplement that has been formulated with their needs in mind and without ingredients that may be harmful, such as caffeine, for a growing body.

A Clear Ingredient List

It’s important to read the nutrition facts label and the ingredient list when choosing a kids’ supplement. Check to make sure the nutrients you want are included at sufficient amounts. For example, if you are wishing to increase vitamin D or iron by taking a multivitamin, you need to confirm those nutrients are actually included. There are no standards of inclusion in the supplement industry. 

Third-Party Tested

The supplement industry is not regulated by the government in the same way the food industry is regulated. Therefore, it’s best to look for a supplement that has been third-party tested for safety. Look for the “NSF Certified” seal ensures that the supplement has been tested for contaminants as well as certifies the supplement contains the ingredients it says it does.

Summary

Adding a supplement to your kid’s routine is a decision that should be made with a trusted healthcare provider. If you choose to start a supplement, make sure to check it for age-appropriate formulation, a clear ingredient list and verify that it is third-party tested.
