Our Top-Rated Pediatric Probiotic
Seed PDS-08® Pediatric Synbiotic
The Gold Standard for Children’s Gut Health
The best choice for parents seeking a sugar-free, clinically-validated, and rigorously-tested synbiotic to support their child’s digestive, immune, and respiratory health.
What Childhood Challenges Does PDS-08 Address?
PDS-08 is formulated with three distinct probiotic blends to support a child’s developing microbiome and address common health concerns through scientifically-backed mechanisms.
Digestive Health & Regularity
The core of the formula is designed to support gut comfort and healthy, regular bowel movements, a benefit directly confirmed in its clinical trial.
Respiratory Health
Includes strains clinically studied for their role in the gut-lung axis, supporting healthy immune responses in the upper respiratory tract, especially beneficial during school seasons.
Dermatological Health
The formula includes strains studied for their role in the gut-skin axis, contributing to healthy skin by supporting gut barrier function and modulating immune responses.
Ingredient Deep Dive: A Scientific Breakdown
The efficacy of a probiotic is determined by its strains. PDS-08 contains 9 well-researched strains (24.5 Billion AFU) and a high-dose prebiotic blend, making it a powerful synbiotic.
| Component | Details & Scientific Rationale |
|---|---|
| Probiotic Strains (Select Highlights) |
|
| Prebiotic Blend (MAOS™) |
6.09g FOS & Inulin (from Jerusalem Artichoke & Chicory) This high dose of short- and long-chain prebiotic fibers is designed to selectively nourish the probiotic strains and other beneficial gut bacteria. Note: As these are FODMAPs, PDS-08 is not suitable for children with known FODMAP intolerances. |
| Delivery System |
Microencapsulation & SHIME® Validation Select strains are microencapsulated to protect them from stomach acid. The entire formula is validated using SHIME®, a sophisticated model of the human gut, to ensure the probiotics survive and are active in the colon. |
Deep Dive: The PDS-08 Experience & Clinical Evidence
The Gold Standard: A Product-Specific Clinical Trial
Evidence, Not Just Ingredients
Seed’s most significant differentiator is its investment in a 12-week, randomized, double-blind, placebo-controlled trial on the final PDS-08 formula. This is the gold standard of clinical research and is exceptionally rare in the supplement industry.
The study, involving 64 children aged 3-17, found that PDS-08 significantly increased weekly bowel movements in children with intermittent constipation compared to a placebo. It also maintained healthy regularity in other children without causing issues. Critically, the formula was exceptionally well-tolerated, with no reported gastrointestinal side effects like gas or bloating, despite its high fiber content.
Expert Insight
“The decision to conduct an RCT on the final PDS-08 product, rather than just relying on ‘borrowed science’ from ingredient studies, is what sets Seed apart. It provides direct, credible evidence that this specific combination of strains and prebiotics works as intended and is safe for children. This is the level of rigor parents and pediatricians should demand.”
Safety & Quality: A Parent’s Primary Concern
When it comes to children, nothing is more important than safety. Seed’s quality control protocols are arguably the most rigorous in the industry.
Unprecedented Third-Party Testing
Every batch of PDS-08 is tested not only for potency but also for a vast array of potential contaminants.
- 500+ Contaminants: Tested for pesticides, herbicides, and glyphosate.
- Heavy Metals: Screened for lead, mercury, arsenic, and cadmium.
- 14 Major Allergen Classes: Validated to be free from common allergens as defined by the European Food Safety Authority (EFSA).
- Microbiological Contamination: Tested for harmful bacteria like E. coli and Salmonella.
A Formula Built on Trust
Beyond testing, safety is built into the formulation itself.
- No Unnecessary Additives: Free from sugar, artificial flavors, colors, sweeteners, and preservatives.
- Strain-Level Safety: Each probiotic strain has GRAS or QPS status, the highest safety designations.
- Controlled Supply Chain: Sold directly from Seed, eliminating the risk of counterfeit or improperly stored products.
PDS-08 vs. The Competition
Here’s how PDS-08 stacks up against other leading pediatric probiotics available in Canada.

| Approx. Price/Day | ~$1.33 | ~$0.70 | ~$0.44 | ~$0.93 |
Cost vs. Value: What Are You Paying For?
PDS-08 is a premium product with a price of $39.99/month (~$1.33/day). While cheaper options exist, they don’t offer the same level of scientific validation or safety assurance. The cost covers:
- A high-potency dose of 9 specific, premium probiotic strains.
- The backing of a product-specific randomized controlled trial.
- The industry’s most comprehensive third-party testing program for purity and safety.
- A counterfeit-proof supply chain to guarantee product integrity.
- Sustainable, eco-friendly packaging with a refill system.
With PDS-08, you are paying for certainty and peace of mind, not just a bottle of pills.
Who Is PDS-08 Best For? Our Final Verdict

Choose Seed PDS-08 if…
You are a parent seeking a scientifically sound solution for a child with documented intermittent constipation, as this aligns directly with the positive outcome of the product’s clinical trial.

Parent’s Checklist for Choosing a Kids’ Probiotic
Use this checklist to evaluate any children’s probiotic supplement.
-
Does it have a product-specific clinical trial?
This is the highest level of evidence. Has the company invested in research on its specific formula? PDS-08 has.
-
Does it list specific, alphanumeric strains?
Vague names like “Lactobacillus acidophilus” are not enough. Demand strain-level specificity (e.g., *L. acidophilus* NCFM) to verify research.
-
Is it sugar-free?
Avoid sugary gummies and chewables that can contribute to poor dental health and picky eating habits. Look for a zero-sugar formula like PDS-08.
-
Is there proof of third-party testing for contaminants?
The company should provide transparent evidence of testing for potency, purity, and common contaminants like heavy metals and pesticides. Seed excels here.
Frequently Asked Questions
Is Seed PDS-08 safe for my child?
Yes. PDS-08 is formulated for children ages 3-17. Its ingredients are clinically studied for safety in pediatric populations and it undergoes the most rigorous third-party testing in the industry for contaminants and allergens. Its own clinical trial confirmed it was exceptionally well-tolerated.
What does PDS-08 taste like?
PDS-08 is unflavored and odorless. When mixed into food like yogurt or a drink like a smoothie, it’s virtually undetectable, making it perfect for even the pickiest eaters.
Is PDS-08 suitable for kids with allergies or FODMAP sensitivity?
PDS-08 is tested and verified to be free from 14 major allergen classes, including gluten, dairy, soy, and nuts. However, its prebiotic blend contains FOS and inulin, which are high-FODMAP fibers. Therefore, it is not recommended for children with a known FODMAP intolerance.
How do I give PDS-08 to my child?
Simply mix one sachet daily into cool or room-temperature food or drink. For ages 3-4, it’s recommended to start with half a sachet for the first few days. It should not be mixed with hot foods or beverages, as high heat can damage the live probiotics.
