Brought to you by SGS Nutrasource and the Global Prebiotic Association
Consumers Want Proof. We Help You Deliver It.
The prebiotic market is growing fast, and so is consumer skepticism. With a flood of products making unsupported claims, brands that can demonstrate genuine quality and scientific integrity stand apart from the noise.
The NutraStrong™ Prebiotic Verified program is a third-party certification developed in partnership between the Global Prebiotic Association and SGS Nutrasource, one of the world’s leading supplement testing and certification bodies. It gives your brand or ingredient a credible, independent mark of verified quality.
Who Can Get Certified?
The NutraStrong™ Prebiotic Verified program is open to companies whose products can meet the scientific and quality standards required for certification.
Raw Material Suppliers
Prebiotic ingredient suppliers seeking to differentiate their materials with independent verification.
Finished Product Brands
Consumer brands with finished dietary supplements or functional food products containing prebiotics.
Food & Beverage Companies
Brands incorporating prebiotic ingredients into food and beverage formats with efficacious dosing.
Natural Health Products
Natural health product companies looking to substantiate prebiotic claims with third-party science.
What Verification Includes
Every brand or ingredient manufacturer that earns the NutraStrong™ Prebiotic Verified mark has passed a comprehensive, multi-point review conducted by SGS Nutrasource’s scientific staff.
Product Specification & Analytical Review
A thorough review of your product specification sheet and analytical data, including Certificate of Analysis verification to confirm accuracy and consistency.
Ingredient Dosage Confirmation
Confirmation that the prebiotic ingredient is present at the dose claimed on your label — a critical standard in a category where underdosing is rampant.
Clinical Evidence Review
At least one randomized, controlled trial demonstrating microbiome modulation and a health benefit resulting from the ingredient’s or product’s specific dose effect is required.
Lab & Manufacturer Accreditation
Verification that the testing laboratory and manufacturer hold current, recognized accreditations — ensuring quality extends throughout your supply chain.
Label Compliance Review
An initial label overview and regulatory compliance check, including allergen and certification claim review, with an annual follow-up to confirm any changes.
Ongoing Support
Certification isn’t a one-time event. Annual reviews ensure your product continues to meet program standards as formulas and regulations evolve.
Built on the NutraStrong™ Platform
The Prebiotic Verified program sits within the NutraStrong™ certification platform — a broader quality standard covering all categories of the supplement, food, and natural health product industry. Developed by SGS Nutrasource, NutraStrong™ establishes a comprehensive baseline across four core pillars.
Testing Standards
Products are reviewed for adequate test results. Multiple testing options are available, including COA review with per-lot verification and direct sample submission for full testing parameters.
Label Compliance
Label review against specification sheets, allergen and certification claim verification, and annual follow-up to track changes — ensuring what's on the label matches what's in the product.
Manufacturing Practices
GMP or equivalent certification verified at program initiation and annually. Accepted standards include GMP, HACCP, ISO, NSF, USP, and other recognized quality marks.
Corporate Values
Showcase your company's commitment to sustainability, cause marketing, and industry stewardship. Relevant third-party certifications and charitable programs are featured in your product profile.
