Vitamins for Kids
What You Need to Know

Do little ones, especially picky eaters need supplements aka a vitamin? Do they make a special vitamin for picky eaters? We know that a child with a nutritional deficiency can put him/her at risk for other nutrition related problems. When growing, kids require nutrients to continue to grow their brain, to grow taller, and to grow stronger. So how can you tell?

Does your kid need a vitamin?

There are a handful of ways to know when it is time to talk with your child’s doctor about a serious nutritional deficiency. Luckily, since the 1920s, multiple items in our pre-packaged food supply has been fortified with nutrients like iodine, vitamin D, and calcium for several decades, which has helped to prevent more widespread nutritional deficiencies in most of the US population.

However, you’re reading this because your kid is picky! So if you have a selective eater, below are some areas you may want to play closer attention to your child’s diet to know if you should consider a vitamin for picky eaters.


First, let’s look at calories. With nutritional deficiencies, a child can have a long-term deficiency or a short-term deficiency. We worry most about long-term deficiencies. A long-term deficiency in calories (energy) can cause the child to not gain the expected amount of weight for age. Further, this can cause the child to not grow as tall as they would have had they had sufficient calorie intake long-term. You can ask your child’s doctor for growth charts at each visit, which can show you if they are following their growth curve for weight and height, based on their age and gender. Want more?

Next up, iron. Long-term deficiencies of vitamins and/or minerals from a limited diet may cause easy-to-spot symptoms that can help you know when to worry. For example, if your child’s diet doesn’t contain any meat (beef, pork, chicken, turkey) and your child is not on a multivitamin supplement, they could be at risk for an iron-deficiency. This risk could be higher, if your child was or is breastfed. Iron is found in plant-foods as well and in dried fruits, but this type of iron is different, and therefore may not be enough iron to prevent a deficiency if your child is also working to improve picky/decreased eating.

Symptoms of iron deficiency may include fatigue, poor appetite, poor growth, unusual cravings for things like dirt, or frequent infections.

Vitamin C, E, B12 and Folate

Another one to watch is B12. Be mindful here if your child doesn’t eat any meat or eggs and is not on any formula or vitamin/mineral supplement. If they don’t love eating fruits or vegetables, they might be deficient in Vitamin C or folate. Lastly, those that avoid leafy green vegetables and nuts could be deficient in Vitamin E.

Deficiencies from picky eating are actually pretty rare

It is very rare for your child to develop deficiencies severe enough to show symptoms from picky eating. A good tip is to check changes in your child’s skin, hair, and general behavior. Also, easier bleeding and bruising can also be worrisome. Moreover, these could be signs of a problem beyond typical picky eating. Read more about when picky eating is a problem.

The Bottom Line: You may not need a vitamin for picky eaters

Yup! That’s right. You may not need a vitamin for picky eaters. You can help to prevent vitamin and mineral nutritional deficiencies by providing an “insurance policy” to your child’s daily routine through a child’s multivitamin/mineral supplement. Check with your doctor about which supplement would be appropriate for your child. One thing to watch is some contain iron and others do not. Also, some supplements have allergens.

Overall, if your child is acting differently than usual, and your mom instincts tell you that something isn’t right, do something and call your doctor. It is always good to double check with your child’s doctor to make sure. Supplements for picky eaters may be right for your family!
