We’re not just editors, we’re also moms who have given clean vitamins to our kids for years. These are our picks for kids’ fiber supplements with natural ingredients that are free from unnecessary sugar, dyes, and additives
As a parent, I’m always looking for anything to make my son’s life easier, healthier, and safer. From time to time, your little one might experience uncomfortable complications such as constipation, which is where a children’s fiber supplement comes in. These can promote regular bowel movements, and fiber is also proven to help with weight control, prevent heart disease and diabetes, and even lower chances of getting some types of cancer.
Fruits, veggies, beans, and whole grains are often recommended for adding more natural fiber into your child’s diet. But as we all know, picky eaters don’t always want dietary fibers. If you’ve noticed those nutritional gaps, you’re not alone — most American children and adults don’t get enough fiber from food alone. When in doubt, trust in these best-selling fiber supplements designed specifically for kids.
What makes fiber supplements safe for kids?
Some fiber supplements are considered safe for children, but the experts at Kaiser Permanente say natural fiber supplements are safest (though they could make your child feel bloated). Keep in mind that the American Academy of Pediatrics (AAP) says, “food-based, natural fibers are recommended over supplements.”
If you can’t get the most natural source of dietary fiber, talk to your child’s doctor about taking a fiber supplement. The AAP also notes that ingesting fiber supplements without enough water can actually worsen your child’s constipation. Make sure your little one stays well-hydrated and follow instructions carefully if you choose to offer a fiber supplement. In more extreme cases, your doctor might prescribe a stool softener or laxative.
Our criteria:
Our team has tested and researched dozens of supplements for kids and scoured thousands of customer reviews to find the best clean fiber supplements for children that are dye-free, formulated without any added or unnatural sugar, and are easy to take. We regularly update this list with emerging options that meet the following criteria:
- CLEAN INGREDIENTS | Each of these options is made with natural and organic ingredients — and is free of additives, dyes, synthetics, and allergens making them safe and beneficial for your kiddos.
- LOW OR NO SUGAR | The last thing we want is for our kids’ vitamins to be loaded with sugar. We’ve ensured each of these supplements contains no or very low amounts of sugar.
- TASTES GOOD & EASY TO SWALLOW | Vitamins that taste good and are easy to swallow help our children get their daily dose of nutrients without any fuss. We’ve researched and can confirm each of these tastes great.
Fiber isn’t the only kid-friendly supplement we’ve written about. You can also browse the best organic kids’ multivitamins.
1. Hiya
Best For | Multiple children or picky eaters
Active Ingredients | Prebiotic fiber blend (organic inulin, resistant vegetable fiber, dragon fruit, psyllium husk), organic pineapple juice, mango fruit, lime fruit, pink Himalayan salt
Daily Dose | One scoop for kids 2 and up, two scoops for kids 4 and up
Prices Starting At | $58 for a 30-day supply
Picky eaters will meet their match with Hiya’s fruity drink mix. The brand’s Kids Daily Fiber+ offers up a daily dose of fiber with an “Island Punch” flavor, courtesy of natural fibers from a blend including dragon fruit and psyllium husk. Pineapple juice, and mango sweeten the deal, and the scoopable products are suited for little ones 2 and older. Simply scoop it, mix it with water, and prepare for a fiber boost in your child’s diet. Parents will also appreciate that there’s zero added sugar, it’s third-party tested, and even scored a Purity Award from the Clean Label Project.
Our editors have waxed poetic about how much we love Hiya, and with good reason. Their supplements are colorful and approachable (The inviting lime green container! The free stickers!), a secret ingredient for any child-friendly product. And for the parents, there’s convenience and a budget-friendly approach to ordering supplements for one, two, or three kids at a time. The company has thought of virtually everything, too, creating a multivitamin, daily probiotic, green powder, and immune system sticks (all of which received a seal of approval from contributing editor Stephanie Fallon).

2. Seed
Best For | Older kids
Active Ingredients | Nine probiotic strains and a fiber-based prebiotic
Daily Dose | One sachet poured and mixed into food or drink
Prices Starting At | $39.99 for a 30-day supply
For a versatile flavor, consider nabbing these sachets from Seed. Each one is powered up with nine probiotic strains and a fiber-based prebiotic, and all you need to do is tear, pour, and add it to your child’s food or drink. Just make sure you only mix it into room temperature or cold items — not anything hot. The brand recommends consuming the supplement within 30 minutes and offering it to your child at the same time each day. If your child loves it, you can use it for years. The product is made for children from age 3 to 17.
Seed products are rigorously tested for more than 20 allergens, including sugar, soy, gluten, dairy, and nuts. Each serving will provide your child with 5 grams of fiber, and the key benefits promoted are gastrointestinal immunity, dermatological health, and respiratory health. Anecdotally, several parents have gushed about this product in the reviews section, sharing that their children experienced fewer sick days and resolved skin issues such as eczema. Who doesn’t love a few bonus benefits, besides the more obvious bowel movement perk?
Customer Review | “This has worked SO well for 2 of my girls who have struggled with constipation and tummy issues. So easy to add to their food or drinks!” – Shelly T. (Read more reviews.)
3. Grüns Kids
Best For | Gummies
Active Ingredients | Vitamin C, zinc, prebiotics, adaptogens, antioxidants, and more vitamins and minerals
Daily Dose | One packet of gummies
Prices Starting At | $45.56 for a 28-day supply
What kid doesn’t love gummies? Made just for your favorite picky eater, Grüns Kids gummy packets are easy to throw in a lunch box and are offered in a strawberry-forward original flavor or an alternative that’s reminiscent of mango sorbet. It should be noted that these are technically labeled as “Superfoods Green Gummies,” not a fiber-specific supplement. That said, each serving delivers 4 grams of dietary fiber, making it a solid source to fill those gaps (Not to mention, it’s one of our editors’ go-to immune vitamins, too.)
To help you save even more, you can purchase a subscription for up to five kids and score up to a whopping 52 percent off your order. (That’s up to 840 gummies at more than half-off!). For anyone concerned about too much sugar in their little ones’ diets, there are also sugar-free gummies. If you’re tempted to try it, fear not — Grüns makes an adult version for kids at heart, too.
Customer Review | “Very impressed with the quality and taste of these. My son is a super picky eater… but he will usually eat these no problem. Thank you!” – Elizabeth B. (Read more reviews.)
4. Culturelle
Best For | Flavorless supplement
Active Ingredients | Probiotic, wheat dextrin, inulin, kiwi fruit powder
Daily Dose | One packet, up to three times per day
Prices Starting At | $20.99 for a 24-pack
We’d be remiss if we didn’t mention the most recommended probiotic brand among pediatricians. For more than 30 years, Culturelle has provided probiotics supporting digestive health and immunity for everyone in the family. Similar to the mix-in from Seed, Culturelle Kids Probiotic + Fiber Packets are flavorless powders you can add to room temperature or cold foods and drinks. The brand suggests stirring it into yogurt or applesauce for best results. And unlike others on our list, it’s safe for babies 1 year and older, and they can take it up to three times per day.
There are two options available for purchase: a 24- or 60-pack. One-time purchases are a bit pricier, or you can subscribe and save 10% on your order. Perhaps the most accessible fiber supplement on the market, you can easily find it at your local Walmart, Target, CVS, and Walgreens.
Customer Review | “All I need for my little one to have daily movements. She is 5 and has been using this for almost a year. She watches me put it in her drink and doesn’t mind because she doesn’t taste it. If I forget and miss a day, she doesn’t have a movement that day or it comes out harder. This is how I know it works!” – MercuryMom (Read more reviews.)
5. MaryRuth’s
Best For | Papaya flavor
Active Ingredients | Soluble tapioca fiber, maltitol, purified water, pectin
Daily Dose | One gummy per day, or as recommended by a physician or healthcare professional
Prices Starting At | $22.46 for a 60-day supply
Another gummy solution, MaryRuth’s Kids Fiber Gummies might be more accepted by pint-size picky eaters due to the papaya flavor and orange color. They look like a delicious candy, but boast so many benefits, including a sugar-free solution with 3 grams of fiber per serving. Many parents rave that it’s quickly become a (fun!) part of their kids’ routine.
Buy this product once, or subscribe and save 10 percent on every order. Plus, deliveries can be scheduled every 15, 30, 45, or 60 days—a major perk for big families. Here’s where it gets even better: MaryRuth Ghiyam is a real person. A certified health coach, chef, and mom of four, she’s at the helm of this brand as the founder and CEO. On top of that, MaryRuth is B Corp and Clean Label Project certified.
Customer Review | “My daughter was experiencing constipation for months, we tried so many things eventually when we got it managed her doctor recommended fiber gummies and we have been using them ever since and she loves them! She even knows ‘one a day’!” – Sarah L. (Read more reviews.)
6. Begin Health
Best For | Fiber supplement with HMOs
Active Ingredients | HMOs, chicory root fiber
Daily Dose | One packet per day for kids 1-3, up to two packets per day for kids 4 and up
Prices Starting At | $33.96 for a 28-pack
Designed as a better-for-you laxative, Begin Health’s Daily Growing Up Prebiotics are fiber supplements many parents shared their doctors recommended. The most unique aspect of this powder is the 2’-FL HMOs, or human milk oligosaccharide, which is “the most abundant prebiotic in breast milk,” per the brand. As for the fiber element, each serving has 3 grams of chicory root fiber. These two main ingredients work together to support healthy digestion and more gentle bowel movements.
If you’re interested in testing out whether the supplement works for your child, start slow. Begin Health advises that parents administer half of a packet at first and gradually increase the amount over the next several days. When you’re mixing, add the flavorless powder to milk, water, or another drink. It can also work with snack foods like yogurt. These are available in packs with 28, 56, and 112 servings. If you select the second option, the family size is offered in two additional flavors: strawberry creamsicle and banana fudgesicle. While it’s allergen-friendly, this product may contain traces of milk so it’s not considered dairy-free.
Customer Review | “I added Begin Health to a smoothie for my son and it was obvious it worked! Tasteless so it was an easy add-on. Thank you for a great product.” – Hannah G. (Read more reviews.)
7. Smarty Pants
Best For | Adding more veggies to your child’s diet
Active Ingredients | Organic greens blend, inulin, pectin, citric acid
Daily Dose | One to two gummies per day
Prices Starting At | $20.70 for a one-month supply
Here’s a fun fact about the Smarty Pants gummies: Consuming two of them will give your child the same amount of fiber as three cups of kale. That’s because of their organic greens blend (a powerhouse trio of kale, broccoli, and spinach) and chicory root fiber. You’ll love all the greens, and they’ll love that they’re hidden behind a delicious mixed berry flavor.
This product is best for kids 4 years and older. During the weeklong trial period, start with one gummy per day before increasing the dose to two daily. For even more supplemental support, you can add the brand’s multivitamin or find the best of both worlds in the Kids Plus Multi & Fiber. Need a little more peace of mind? The brand has also received a Purity Award from the Clean Label Project. Order every month, two months, or three months for bonus savings.
