Wondering what the best fiber supplement for kids is?

I’ve tested some of the top rated supplements to find out which are best. Let’s dig in!

1. SmartyPants Kids Fiber Vitamins

SmartyPants Kids Fiber Vitamins

A great fiber supplement for kids packed with essential nutrients and omega-3s in a tasty gummy form.



The SmartyPants Kids Fiber Vitamins provide multiple health benefits in just one gummy. With essential nutrients like vitamin D3 for strong bones, vitamin B12 for energy metabolism, and omega-3s sourced from wild-caught small fish, these gummies promote overall health for your child.

Additionally, they are free of common allergens like milk, eggs, and peanuts, making them suitable for most kids. However, some parents might find the sugar coating a bit excessive.

While the formulation is the same as the adult version, the convenience of having a single serving for your child makes it a practical choice. Just ensure you check the expiration date before sharing them with your little one. Overall, SmartyPants Kids Fiber Vitamins are a good investment for a healthier and happier child.

2. JoySpring Fiber Supplement Gummies

JoySpring Gummies

Make your child’s digestion hassle-free and boost their immune system with JoySpring Fiber Supplement Gummies.



As a parent, you want the best for your child’s health, and JoySpring Fiber Supplement Gummies is here to help. These gummies not only improve digestion and bowel regularity, but also provide a much-needed immune system boost.

With 5 mg of chicory root fiber per serving, your child won’t miss out on an essential part of their diet. Plus, the vegan gummies are infused with potent immune-boosting ingredients like echinacea, elderberry, and grape root.

However, if your child doesn’t enjoy elderberry and grape flavors, their taste buds might not be thrilled. And although the dosage is flexible, taking 1-3 gummies per day may be less convenient than a single-serving option. Still, JoySpring Fiber Supplement Gummies are worth considering for the benefits they bring to your child’s health.

Unlike some other fiber supplements, this product does not require refrigeration, making it perfect for busy families. HyFiber can be taken directly or mixed with your child’s favorite food or drink, giving you flexibility in how you introduce it.

However, be aware that the product contains orange flavoring, which might not appeal to every child. Additionally, HyFiber is slightly more expensive than some other fiber supplements on the market. But overall, its convenient format and effectiveness make it a reliable choice for supporting your child’s digestive health.

What to Consider When Buying Fiber Supplements for Kids

Consider the Fiber Type

There are two types of fiber: soluble and insoluble. Soluble fiber dissolves in water, while insoluble fiber does not. It is important to choose a supplement that contains both types of fiber for optimal benefits.

Look for Natural Ingredients

Choose a supplement that contains natural ingredients, such as fruit and vegetable fibers, to ensure it is gentle on your child’s digestive system.

Check the Sugar Content

Many fiber supplements contain added sugar, artificial sweeteners, or sugar alcohols. Opt for a product with low or no added sugar to avoid unnecessary calories and potential gastrointestinal issues.

Assess Ease of Use

Consider whether the supplement is easy for your child to consume. Some options include powders, gummies, or chewable tablets. Choose a format that your child will enjoy and be willing to take consistently.

Consult a Healthcare Professional

Before starting your child on any dietary supplement, consult with a healthcare professional to determine the appropriate dosage and to ensure there are no contraindications with existing medications or health conditions.


What is the most effective fiber supplement for child constipation?

There are several effective fiber supplements for children with constipation, but psyllium husk tends to be most popular. It is a natural, soluble fiber that helps soften stools and promotes regular bowel movements. Remember to consult your pediatrician before starting any new supplement.

Which fiber supplements are suitable for 5-year-olds?

For a 5-year-old child, opt for a gentle fiber supplement like flaxseed, chia seeds, or partially hydrolyzed guar gum (PHGG). These can be easily mixed into their favorite foods or drinks. However, always consult your child’s pediatrician before introducing a new supplement into their diet.

Are fiber gummies recommended for 2-year-olds?

It is generally not recommended to give fiber gummies to children under the age of 3. At this age, increasing fiber intake through whole foods like fruits, vegetables, and whole grains is more appropriate for their developing digestive system.

Final Thoughts

There are plenty of great fiber supplements for kids, but my favorite are the SmartyPants Kids Fiber Vitamins.
