Tate & Lyle’s NutraStrong verification validates prebiotic dosage and boosts trust

Tate & Lyle has officially secured NutraStrong Prebiotic Verified certification for four major product lines within its prebiotic fibre portfolio.

The credential covers the company’s Promitor Soluble Fibre, STA-LITE Polydextrose, Euoligo FOS, and Gosyan GOS ranges.  

Administered by SGS Nutrasource and endorsed by the Global Prebiotic Association (GPA), this independent, third-party verification evaluates ingredient brands against rigid scientific criteria for quality, transparency, and clinical substantiation. As consumer demand for gut-health and functional nutrition accelerates, the certification establishes a definitive benchmark for credible formulation in a crowded marketplace.  

What the certification evaluates

The NutraStrong verification process provides an exhaustive, independent review of the underlying data supporting Tate & Lyle’s portfolio. Rather than relying solely on self-reported data, the verification process strictly required:  

• Rigorous analytical review: comprehensive validation of product specifications and analytical testing standards. 
• Clinical dosage confirmation: verification that the ingredient achieves a prebiotic effect at specified dosage ranges, backed by at least one randomised, controlled human trial demonstrating microbiome modulation and a resulting health benefit. 
• Accreditation audits: strict independent verification of laboratory and manufacturing site accreditations.  

For research and development (R&D) teams, brand owners, and food manufacturers, the NutraStrong certification delivers critical commercial and formulation advantages:

1. Absolute confidence in prebiotic label claims

Navigating the regulatory landscape for gut-health claims can be complex. Because the efficacy assessment explicitly identifies the precise dosage range or minimum dose at which a prebiotic effect is clinically demonstrated, manufacturers can formulate with precision. This removes the guesswork from dosage levels required to support legitimate, evidence-based on-pack nutritional claims.  

2. Streamlined multi-category application

The validated ingredient lines are highly versatile and engineered to be incorporated into a wide variety of everyday applications. Manufacturers can confidently deploy these fibres across diverse sectors — including beverages, dairy, bakery, snacks, cereals, bars, and dietary supplements — without compromising the final product’s taste profile.  

3. Heightened consumer trust and clarity

In a fast-evolving marketplace, consumers are increasingly sceptical of unverified wellness claims. Utilising an independently verified ingredient allows food and beverage brands to offer transparent, best-in-class products that bring much-needed clarity, credibility, and confidence to both brands and consumers.  

Capitalising on the era of fibre

The launch comes at a time when prebiotic fibre formulation is moving from niche supplements into mainstream, everyday food and beverage categories.  

“This certification recognises the strength and depth of the science underpinning our fibre portfolio and our continued commitment to advancing evidence-based nutrition,” stated Katie Adolphus, nutrition science lead, fibres at Tate & Lyle. “For us, fibre innovation starts with human health. It must be grounded in credible science, translated responsibly, and ultimately delivered in ways that make a meaningful difference to everyday diets, without compromising taste.”

Kevin Yan, vice president of product certifications at SGS Nutrasource, added: “The NutraStrong programme is reserved for best-in-class branded ingredients and we are delighted to welcome Tate & Lyle to our ranks during what can be only described as the era of fibre. In a crowded and rapidly evolving fibre landscape, certification brings much-needed clarity, credibility, and confidence — for both brands and consumers.”

The certified Promitor, STA-LITE, Eupligo, and Gosyan ingredient lines are available globally for food and beverage manufacturers looking to upgrade their functional health profiles.
