Kids Daily Prebiotic Fiber

You can find more information on the science of prebiotics within the Our Science page. Head over there for a detailed deep dive!

PHGG (Partially Hydrolyzed Guar Gum)
Partially Hydrolyzed Guar Gum (PHGG) is a soluble, prebiotic dietary fiber that plays a few key roles in supporting different metabolic processes:

Prebiotic
PHGG promotes the growth of beneficial bacteria by serving as a substrate or food source for these microbes. When PHGG reaches the colon undigested, it undergoes fermentation by beneficial bacteria such as Bifidobacteria and Lactobacilli. During fermentation, these bacteria break down PHGG into short-chain fatty acids (SCFAs) and other metabolites.

SCFA Production
PHGG undergoes fermentation by gut bacteria in the colon, leading to the production of short-chain fatty acids (SCFAs). These SCFAs, like butyrate, provide energy for colonocytes and create an acidic environment that favors the growth of beneficial bacteria while inhibiting the growth of harmful pathogens.

Anti-inflammatory Properties
SCFAs produced from the fermentation of PHGG have anti-inflammatory properties that help neutralize harmful free radicals and reactive oxygen species (ROS).Bio.me uses a PHGG fiber that is tasteless, colorless, and odorless, so it can easily be added to beverages and food. Because of the enzymatic pre-digestion, PHGG dissolves easily without the gumminess of many other fibers, and it causes far less gas and bloating than non-hydrolyzed guar gum.

No. It was very important to us to be free of the FDA’s Top 9 Allergens (milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soybeans, and sesame). We are also gluten-free, glyphosate residue free, Non-GMO Project Verified, and do not use any corn, soy, or grain derivatives.

Fiber is a normal and important part of a child’s diet. Introducing fiber gradually and choosing gentle sources can help support tolerance.

Some fibers can if introduced too quickly. Starting low and increasing slowly helps support comfort.

Many children can benefit from gentle fiber support. Parents should always consider their child’s age, diet, and individual needs.

Yes. PHGG has been investigated in dozens of pediatric research studies in controlled settings with consistent results showing it is well tolerated across a range of doses and that it supports digestive comfort and more regular bowel habits.

Consistency matters. Digestive benefits are most recognized with regular use and daily use is encouraged. Parents often describe more predictable bathroom habits, softer stool consistency, and a sense of digestive ease over time.

No, whole foods should remain an important and primary source of nutrients and naturally occurring fiber. PHGG can be used as an additional support when kids fall short on fiber intake and need a consistent daily routine.

We created two versions to match developmental needs. For kids age 1+, our Unflavored Daily Prebiotic Fiber contains only PHGG fiber. This keeps the ingredient list simple and makes it easy to mix into anything without changing taste. It has also been clinically studied for safety and benefits in 1 year olds. For kids ages 4+, we also offer naturally flavored options because kids at this age may prefer flavor variety. The core ingredient, PHGG, stays the same. The difference is simplicity for younger children and flavor choice for older kids.
