1. Certified Free From (CFF)

The Certified Free From (CFF) program by MenuTrinfo is a third-party certification designed to validate allergen-free claims. Its purpose is to address a major issue in the supplement industry: undeclared allergens, which are the leading cause of most Class 1 product recalls.

Covered Allergens or Sensitivities

The CFF program ensures thorough allergen coverage. Starting January 6, 2025, MenuTrinfo updated its certification to align with FDA allergen labeling guidelines. Now, there are two versions of the CFF seal: one that includes all FDA-defined tree nuts (including coconut) and another that excludes coconut, clearly marked with a disclaimer[4]. This update is particularly vital as over 32 million Americans live with food allergies to one or more major allergens[8].

Verification Process

The certification process for CFF is stringent, going well beyond basic ingredient checks. MenuTrinfo employs standardized testing to ensure allergen-free integrity throughout production. The process includes several key steps:

• Supplier and ingredient approval
• Operations review
• Testing of food contact surfaces
• Final seal approval[8]

Trained auditors from ASI, certified in food allergen management, conduct detailed reviews of procedures and perform annual facility inspections to prevent cross-contact. The program is accredited by the ANSI National Accreditation Board (ANAB) and complies with ISO 17065 standards, ensuring it meets international benchmarks for accuracy and dependability through yearly ANAB audits[8]. This rigorous system builds consumer confidence in the certification.

Consumer Trust and Transparency

In 2021, 61% of consumers reported being more likely to buy an allergen-free product displaying the CFF seal. Betsy Craig, president and CEO of MenuTrinfo, highlighted the importance of this trust:

"The CFF seal delivers confidence to the consumer through our internationally accredited standards and scheme certification. We believe it is time to treat the food allergic community with the same transparency, respect and solution as we do those that need a gluten-free option”

By eliminating vague claims, the CFF certification offers verified assurance through routine testing, annual audits, and regular ingredient reviews.

Relevance to Allergen-Conscious Consumers

For the 85 million Americans seeking products free from at least one major allergen, the CFF certification provides essential peace of mind. Addressing these concerns, a MenuTrinfo Client Relations Specialist shared:

"In over 30 years leading food safety teams in food manufacturing plants, I always wondered when allergens would be taken more seriously. Now that CFF is here and accountability exists at the manufacturing level, it leads to validated packaging seals for the consumer. Soft claims are simply not good enough for my daughter.”

This detailed process underscores NutriFitt's commitment to ensuring safety and transparency in every product, empowering consumers to navigate the allergen-free market with confidence.

2. NSF Certified for Sport

The NSF Certified for Sport program is a specialized certification designed to ensure supplements are free from substances banned by major sports organizations. While its primary focus isn't allergens, its stringent standards for purity and label accuracy make it a trusted choice for consumers with sensitivities. The rigorous verification process is the backbone of its reliability.

Verification Process

The NSF certification process is thorough and leaves little room for error. It begins with strict adherence to Good Manufacturing Practices (GMP), requiring facilities to undergo annual or bi-annual audits to meet federal dietary supplement regulations. During these audits, NSF evaluates facilities under GMP guidelines and tests every production lot for 290 banned substances, including stimulants, narcotics, steroids, diuretics, beta-2-agonists, and masking agents.

Consumer Trust and Transparency

NSF operates as an independent, accredited organization dedicated to global health protection. This independence strengthens its credibility, making the NSF mark one of the most trusted symbols in the supplement industry. Products with this certification are respected by consumers, manufacturers, retailers, and regulatory agencies because they guarantee the absence of unsafe contaminants, prohibited substances, or masking agents. Moreover, the certification ensures that the product contents align perfectly with the label.

This transparency has earned NSF recognition from major sports organizations, with NSF Certified for Sport products making up 57% of the sports supplement market.

"Certified for Sport® gives both my athletes and myself the reassurance we need that the dietary supplements we choose have been tested and certified for quality, purity and safety."
– Leslie Bonci, MPH, RD, CSSD, LDN, Kansas City Chiefs Sports Dietitian, Klean Athlete® Sports Nutrition Advisor

For athletes and meticulous consumers alike, this certification inspires confidence, ensuring every ingredient is accounted for.

Relevance to Allergen-Conscious Consumers

Although primarily designed for athletes, the NSF certification process also benefits allergen-conscious consumers by verifying product integrity through rigorous testing and label accuracy. Additionally, NSF offers a gluten-free certification that adheres to the FDA's Gluten-Free Labeling Final Rule, reflecting its dedication to addressing diverse consumer needs.

"NSF has created a complete program where my unique certified organic, Non-GMO Project verified, certified gluten-free and Certified for Sport® products are traceable, verified and certified from 'cradle to shelf.' This type of third-party auditing helps us provide our customers with full assurance and 100% traceability."
– Jeffrey Brams, General Counsel and VP of Science

For NutriFitt customers, this certification is invaluable - it ensures performance-enhancing supplements are also safe for those with allergen concerns. Whether you're an athlete or someone with specific dietary needs, NSF's commitment to safety and transparency delivers peace of mind.

3. Certified Gluten-Free

The Certified Gluten-Free label represents a high standard designed to protect individuals with celiac disease and gluten sensitivities. To earn this certification, products must contain no more than 10 parts per million (ppm) of gluten - half the FDA’s limit of 20 ppm. This stricter threshold ensures an added layer of safety for consumers. NutriFitt proudly aligns this certification with its broader commitment to supplement quality and safety.

Covered Allergens and Sensitivities

This certification specifically addresses gluten from wheat, barley, and rye. Certified products cannot include barley-based ingredients, which are a common source of gluten contamination. Even naturally gluten-free grains and legumes can encounter gluten during harvesting, storage, or transportation. That’s why certification is so important - it guarantees that products meet strict safety standards and remain uncontaminated.

5. Non-GMO Project Verified

The Non-GMO Project Verified certification is a well-known and trusted label in North America for those looking to avoid genetically modified organisms (GMOs). While this certification doesn’t specifically address allergens like dairy or nuts, it complements allergen-free certifications by ensuring ingredients are sourced without genetic modification. For health-conscious consumers, this label provides reassurance that their supplements are free of GMOs.

Covered Allergens or Sensitivities

For individuals seeking supplements with pure and unaltered ingredients, the Non-GMO Project Verified seal ensures that products are made without genetic engineering or GMO-derived components. Some consumers opt for non-GMO products due to concerns about the potential link between GMOs and the rise in food allergies and intolerances. The certification enforces a strict threshold of 0.9% for GMO contamination, aligning with the European Union's mandatory labeling standards. It specifically targets high-risk crops such as corn, soy, canola, sugar beet, alfalfa, papaya, zucchini, potato, cotton, and apple. According to USDA estimates, as much as 70% of packaged foods in the United States contain GMOs or their derivatives, highlighting the importance of this certification.

Verification Process

The Non-GMO Project follows a thorough and detailed verification process that typically takes between 3 to 6 months. This process involves four independent technical administrators to ensure an impartial evaluation [28]. As described by the Non-GMO Project:

"Non-GMO means a product was produced without genetic engineering and its ingredients are not derived from GMOs. Non-GMO Project Verified specifically means that a product is compliant with the Non-GMO Project Standard, which includes stringent provisions for testing, traceability, and segregation."

Verification includes DNA-based testing conducted at key control points by ISO-17025 accredited labs. Companies must also submit extensive documentation - such as invoices, certificates of analysis, and standard operating procedures - to confirm ingredient sourcing. For products with high-risk GMO inputs, custom sampling plans are implemented to ensure statistical confidence. To maintain certification, products undergo annual evaluations and random ingredient testing.

Consumer Trust and Transparency

The Non-GMO Project Verified seal has become a symbol of trust for consumers, with sales of verified products growing by about 20% over the last three years. According to the Non-GMO Project:

"The Non-GMO Project Verified seal is the fastest-growing label in the natural products industry...The Butterfly is North America's most trusted label for GMO avoidance and the most widely recognized food certification after USDA certified organic."

This certification emphasizes transparency, offering clear labeling that acknowledges potential contamination risks and the complexities of modern food systems. As of August 1, 2025, the verification fee for most products is $115, though costs may vary depending on the number of products and the presence of high-risk ingredients.

Relevance to Allergen-Conscious Consumers

Although the Non-GMO Project Verified label doesn’t directly address common allergens, it offers added confidence for those prioritizing clean ingredient sourcing. Many consumers choose non-GMO products to reduce potential health risks, including concerns about allergies. When paired with allergen-specific certifications, this seal reinforces NutriFitt’s dedication to producing supplements with integrity. By building on organic standards and emphasizing traceability and segregation, this certification supports consumers managing multiple sensitivities or simply seeking the cleanest possible options for their health.
