One of the many things that parents worry about when it comes to their child’s development is whether they’re gaining enough weight.

While you don’t want obesity to become an issue, many parents also look to see that their child is gaining enough weight to be healthy. 

If you’re concerned that your child doesn’t weigh enough for their age, you should first speak to your pediatrician. They can confirm if you’re right and can help you decide what route to take to help your child add a few pounds.

Your pediatrician can let you know if you should be looking into vitamins for kids to gain weight.

While kids should be getting vitamins and nutrients from the foods they are eating, some kids need an extra boost. This can come in the form of vitamin supplements. Vitamins can fill the gaps in nutrients they may be lacking in their natural diet.

What Are the Important Vitamins and Minerals for Children?

Each vitamin and mineral helps a specific area of your child’s growth. Your pediatrician can help you decide which vitamins your child may be lacking. Here’s a look at how several key vitamins can help in your child’s development.

Vitamin A

Vitamin A is important for normal growth overall as well as healthy skin. It also helps with vision and tissue repair.

Vitamin B

Vitamin B helps the body to produce red blood cells and helps with metabolic activities. 

Vitamin C

Vitamin C helps to fight off infection and is important for healing. It also helps to strengthen tissue muscles, and skin.

Vitamin D

Vitamin D is for strong bones and teeth. It helps with the absorption of minerals like calcium. Sunlight can stimulate Vitamin D to become active in the body.


Iron is important for kids at all times, but especially during growth spurts. It contributes to the building of muscles and the production of blood.



Calcium is crucial when it comes to the development and maintenance of healthy bones and teeth. All of these vitamins can be found in foods that your child should be eating.

But, if your pediatrician determines that they’re just not getting enough, they may recommend certain supplements that contain these vitamins. These will help them develop appropriately.

Things to Consider When Looking for the Best Vitamins for Kids to Gain Weight

When you’re considering vitamins for toddlers to gain weight as well as older children, there are several areas to look at.

Your Child’s Diet

Think about what your child eats. Are they getting a balanced diet of fruits, vegetables, dairy, and meat? If you’re not sure, check out the government’s ChooseMyPlate site.

This breaks down what your child should be eating on a daily basis and in what amount. Here’s a quick breakdown:

  • Kids should be getting 1.5-4 ounces of whole grains daily. The exact amount depends on their age. 
  • When it comes to veggies, 1-3 cups is sufficient, depending on age. 
  • For fruit, 1-2 cups daily is recommended.
  • Calcium requirements are at 2-3 cups of milk daily. Yogurt and cheese are good milk alternatives.
  • It’s important that kids get 2-6.5 ounces of protein daily, depending on their age.

If your child is not getting these nutrients and is not growing properly, it may be time to talk about vitamins and minerals with your pediatrician.

Supplement Form

While older kids may be able to swallow an actual pill, smaller kids will need a chewable vitamin. If they’re afraid to take it or don’t like the taste, they’re not going to take it.

Some vitamins even come in a liquid form. Find a vitamin that you’re pretty sure they’ll take.

Be Sure the Need is There

Before you buy vitamins for kids to gain weight, be sure the need is there. Talk with your pediatrician about your child’s weight and where they fall on the charts.

You want to be sure that a vitamin supplement is what they need and that there may not be other issues going on. There are other things that may be going on with your child that is preventing them from gaining weight.
