The U.S. functional food market is booming — consumers are eating their way to health with protein-packed snacks, adaptogen chocolates, probiotic granolas, and fortified staples. For international food brands looking to import functional foods into the USA, the opportunity is enormous — but the regulatory framework is significantly more demanding than most domestic food markets.
This guide covers FDA's functional food requirements, import logistics under FSMA, and the distribution strategy that gives international functional food brands the best chance of sustainable U.S. success.
How the FDA Regulates Functional Foods
Unlike the EU, the USA has no specific regulatory category for "functional foods." A functional food is treated as a conventional food — subject to FDA's food safety regulations — regardless of what functional ingredients it contains. This has important implications for labeling, claims, and import compliance.
Nutrition Facts Panel (Not Supplement Facts)
All conventional foods — including protein bars, fortified snacks, and adaptogen foods — must use the updated FDA Nutrition Facts panel. The updated format (mandated since 2021) includes added sugars declaration, updated serving sizes based on realistic consumption amounts, and bolded calorie and serving size information. International brands accustomed to EU or Australian nutrition labeling formats will need to redesign their panels for FDA compliance.
Claims Limitations
Functional foods can make nutrient content claims ("Good source of protein," "High in fiber," "No added sugar"), authorized health claims ("Diets low in sodium may reduce the risk of high blood pressure"), and qualified health claims (which require FDA review). They cannot make structure/function claims the way dietary supplements can — this is one of the most common mistakes international functional food brands make on U.S. labels. Saying "supports gut health" on a probiotic yogurt may seem harmless, but it's technically a structure/function claim that the FDA does not permit on conventional food labels without prior authorization.
GRAS Status for Functional Ingredients
Every functional ingredient in your product must be either an approved food additive or Generally Recognized as Safe (GRAS) for its intended use. This is where many international functional food brands face issues: an ingredient that's approved as a food ingredient in the EU (under the EU's positive list system) may not be GRAS-affirmed in the USA. Common examples include certain novel proteins, plant-based sweeteners, and fortification nutrients at specific levels. A GRAS determination for a novel ingredient requires either an FDA notification or a self-affirmed GRAS determination by a qualified expert panel — both are time-consuming and expensive processes.
FSMA Compliance: The Core Import Framework
The Food Safety Modernization Act (FSMA) fundamentally changed how the FDA regulates imported food. For international functional food brands importing to the USA, two FSMA rules are most relevant:
Preventive Controls for Human Food (PCHF)
Your manufacturing facility must operate under a written Food Safety Plan that includes: hazard analysis (identifying biological, chemical, and physical hazards), preventive controls (steps to minimize identified hazards), monitoring procedures, corrective actions, verification activities, and record-keeping. This is a more comprehensive requirement than ISO 22000 or BRC certification — though facilities with those certifications are well-positioned to develop an FSMA-compliant Food Safety Plan.
Foreign Supplier Verification Program (FSVP)
Your U.S. importer is responsible for verifying that your foreign facility meets FDA's food safety standards — equivalent to what would be required of a domestic U.S. food producer. The FSVP importer must: conduct supplier verification activities (onsite audits, food safety record reviews, or end-product testing), document those activities, and be able to produce records on FDA request. This is why choosing the right U.S. import partner matters: a distributor or importer who doesn't have FSVP processes in place creates significant compliance risk for your brand.
Labeling Requirements for Imported Functional Foods
Beyond the Nutrition Facts panel, U.S. food labeling requirements include:
- Ingredient statement: All ingredients listed in descending order of predominance by weight, including sub-ingredients of compound ingredients, using FDA-approved names
- Allergen declaration: The nine major allergens (milk, eggs, fish, shellfish, tree nuts, peanuts, wheat, soybeans, sesame) must be declared — sesame was added in 2023 and many international labels still miss this
- Net weight in dual measure: Both metric and U.S. customary units (oz/lb and g/kg)
- Manufacturer/distributor statement: Name and address of the U.S. distributor or importer can be used if labeled "Distributed by" or "Imported by"
- Country of origin: Required on most food products
- UPC barcode: GS1 US-compliant barcode required for retail distribution
Distribution Channels for Functional Foods
Natural & Specialty Grocery (Whole Foods, Sprouts, Natural Grocers)
The primary channel for premium international functional food brands. Whole Foods has been a strong launching point for innovative international food brands — particularly those from markets with established functional food traditions (Japan, Scandinavia, Germany). Access typically requires working through KeHE or UNFI, which distribute to Whole Foods and most natural grocery chains. A broker or distributor with existing KeHE placement is the fastest path.
Conventional Grocery (Kroger, Albertsons, Publix)
Larger scale, lower margin, highly competitive. Conventional grocery buyers are sophisticated and expect established velocity data (typically from natural retail or Amazon) before committing to placement. This channel is typically a Year 2 or Year 3 target for most international functional food brands.
Amazon Grocery & Specialty Food
Amazon's grocery and specialty food categories are highly competitive but accessible for new brands. Amazon's Subscribe & Save program can provide predictable recurring revenue for snack and staple functional foods. The challenge is winning the Buy Box and ranking in competitive protein bar and snack categories dominated by established U.S. brands.
Foodservice & Corporate Wellness
A frequently overlooked but potentially high-volume channel for functional foods — corporate cafeterias, office snack delivery programs (Snack Nation, Caroo), airline catering, and hotel minibar programs. This channel requires custom packaging (often case quantities) and relationships with foodservice distributors or group purchasing organizations.
DTC Subscription
Functional food brands with a compelling subscription angle — monthly snack box, wellness pantry replenishment, customized nutrition plans — have found strong DTC subscription models in the USA. This requires a U.S. 3PL partner and efficient parcel shipping economics, but builds direct consumer relationships that are highly valuable for brand development.
Choosing a U.S. Functional Food Import and Distribution Partner
The right U.S. partner for an international functional food brand needs both food import expertise (FSMA, FSVP, FDA registration) and retail distribution capability. Many supplement distributors are not equipped to handle food imports — the compliance framework is sufficiently different that experience matters.
