Launching a functional food, gummy, or powdered wellness product in the United States requires navigating one of the most critical regulatory decisions in brand building: should your product carry a Nutrition Facts panel or a Supplement Facts panel?
This decision isn't just about aesthetics or marketing — it dictates your entire legal framework under the U.S. Food and Drug Administration (FDA). 21 CFR 101.9 governs Nutrition Facts for conventional foods and beverages, while 21 CFR 101.36 governs Supplement Facts for dietary supplements under the Dietary Supplement Health and Education Act (DSHEA) of 1994.
Selecting the wrong panel can lead to immediate FDA Warning Letters, product recalls, or claims of selling unapproved food additives. Below is the definitive 3-Step Test used by regulatory lawyers and compliance experts to legally classify functional foods, gummies, powders, and beverages.
1. Quick Reference: Nutrition Facts vs Supplement Facts at a Glance
Before walking through the test, here is the side-by-side regulatory comparison that every CPG founder and QA director should keep on hand.
| Regulatory Feature | Conventional Food (Nutrition Facts) | Dietary Supplement (Supplement Facts) |
|---|---|---|
| Primary Regulation | 21 CFR § 101.9 | 21 CFR § 101.36 |
| Serving Size Basis | Must strictly follow FDA RACCs ([21 CFR 101.12](https://www.ecfr.gov/current/title-21/chapter-I/subchapter-B/part-101/subpart-A/section-101.12)) | Set by manufacturer based on suggested daily dosage |
| Ingredient Safety Standard | Must be Generally Recognized as Safe (GRAS) or an approved Food Additive | Dietary Ingredients (vitamins, minerals, herbs, amino acids, NDIs) |
| Proprietary Blends | Prohibited — all ingredients listed by weight | Permitted — blend total weight declared, individual amounts hidden |
| Non-RDI / DRV Ingredients | Cannot appear inside the panel box | Can appear in the panel box below the hairline divider |
| Claims Permitted | Nutrient Content Claims, Health Claims (FDA-approved) | Structure/Function Claims (requires FDA 30-day notice & disclaimer) |
2. The 3-Step Legal Classification Test
To determine whether your product requires a Nutrition Facts panel (21 CFR 101.9) or a Supplement Facts panel (21 CFR 101.36), evaluate your formulation, packaging, and marketing through these three sequential steps. Answer each question honestly — the first decisive "YES" locks in your panel type.
Is the product represented as a beverage, snack, or meal?
Is it a traditional capsule, tablet, softgel, or liquid dropper?
Are the ingredients non-GRAS dietary botanicals, or are you making Structure/Function claims?
Step 1: Statement of Identity & Product Representation
The FDA explicitly states under the Federal Food, Drug, and Cosmetic Act (FD&C Act) that a dietary supplement cannot be represented for use as a conventional food or as a sole item of a meal or the diet. When evaluating Step 1, ask: how is the consumer intended to perceive and use this product?
- Product Name & Terminology — If your product name includes traditional food or beverage terms such as "Soda," "Iced Tea," "Sparkling Water," "Snack Bar," or "Cookie," the FDA will classify it as a conventional food regardless of any active botanical ingredients added.
- Packaging & Appearance — Packaging that mimics standard food/beverage formats — such as a 12 oz aluminum soda can, a standard juice bottle, or a grocery chip bag — signals to consumers that it is a food.
- Marketing Claims & Sensorial Purpose — If labeling or advertising highlights attributes like "refreshing," "thirst-quenching," "great with dinner," or "replaces lunch," the FDA considers it a conventional food. Dietary supplements are intended to supplement the diet, not satisfy hunger or thirst.
Step 2: Physical Form and Delivery Method
The delivery format heavily influences regulatory classification.
Traditional Supplement Forms. If your product is delivered as a capsule, tablet, softgel, liquid dropper/tincture, or a powdered sachet explicitly labeled as a single daily dosage unit, it naturally aligns with 21 CFR 101.36 (Supplement Facts).
Gray-Area Forms (Gummies, Powders, Chews, Bars). Modern delivery forms blur the lines between food and supplements:
- Gummies can be legally classified under either panel. If marketed as a "candy snack," it's 101.9. If marketed with dosage directions (e.g., "Take 2 gummies daily for sleep support"), it's 101.36.
- Powders — protein powders, greens blends, and pre-workouts can be either. A meal-replacement shake powder falls under 101.9 (Nutrition Facts with RACC serving sizes). A concentrated electrolyte or localized herbal powder falls under 101.36 (Supplement Facts).
- Nutrition Facts (101.9): Serving sizes must adhere strictly to FDA Reference Amounts Customarily Consumed (RACC) in 21 CFR § 101.12 (e.g., 240 mL for beverages, 30 g for snacks).
- Supplement Facts (101.36): Serving size is determined by the manufacturer's recommended daily usage (e.g., "1 Scoop (5 g)" or "2 Capsules").
Step 3: Ingredient Profile & Claim Intent
The safety standards and allowed active ingredients differ fundamentally between the two panel types.
- Every ingredient must be GRAS or an approved Food Additive
- Strict limits on novel extracts
- Standard NLEA formatting
- Botanicals like ashwagandha frequently not GRAS for food use
- Dietary ingredients: vitamins, minerals, herbs/botanicals, amino acids
- Proprietary blends permitted
- New Dietary Ingredient (NDI) notification may apply
- Designed to supplement the diet
1. Safety Status: GRAS vs. Dietary Ingredients.
- Conventional Foods (101.9): Every ingredient must be either an approved Food Additive or Generally Recognized as Safe (GRAS) for its intended condition of use. Novel botanicals, ashwagandha, or adaptogenic mushrooms are frequently not GRAS for food use — adding non-GRAS substances to conventional food renders it adulterated.
- Dietary Supplements (101.36): Ingredients can be vitamins, minerals, herbs/botanicals, amino acids, or dietary substances used to supplement the diet. If using a "New Dietary Ingredient" (NDI), an NDI notification under Section 413 of the FD&C Act (21 U.S.C. 350b) may be required if the ingredient was not marketed in the United States prior to October 15, 1994.
2. Label Claims & FDA Disclaimer.
- Structure/Function Claims on Supplements: Allowed (e.g., "Supports focus and clarity"), but require the mandatory FDA disclaimer:
"These statements have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease."
- Structure/Function Claims on Conventional Food: Must relate only to taste, aroma, or basic nutritive value, unless supported as a general structure/function claim that does not imply supplement status.
3. Breakdown of "Gray Area" Product Categories
The hardest classification calls land on products that physically resemble food but are formulated like supplements. Here is how the FDA typically rules on the three most contested categories.
1. Functional Gummies (Vitamin C, Creatine, Melatonin)
→ Supplement Facts (101.36) IF:
Labeled with clear usage instructions ("Take 2 gummies daily before sleep"), packaged in child-resistant or supplement-style bottles, and containing active dietary ingredients like melatonin or nootropics.
→ Nutrition Facts (101.9) IF:
Sold as "gummy candy," consumed for taste/snacking, packaged in tear-open snack bags, or lacking specific dosage limits.
2. Wellness & Protein Powders
→ Nutrition Facts (101.9) IF:
Marketed as a meal replacement, macro-focused protein shake, or baking powder substitute. Serving sizes must match RACC guidelines.
→ Supplement Facts (101.36) IF:
Formulated with high-potency micro-nutrients, adaptogens, or proprietary blends intended to supplement specific bodily functions (e.g., pre-workout energy, liver detox powder).
3. Energy Drinks & Functional Beverages
→ Nutrition Facts (101.9) IF:
Sold in standard single-serve beverage cans, recommended for hydration/refreshment, or named "Energy Tea / Sparkling Juice."
→ Supplement Facts (101.36) IF:
Sold in concentrated "liquid shots" (typically 2 oz), with explicit directions to consume once daily as a dietary supplement, and containing supplement-only botanicals.
4. Technical Formatting Differences: 21 CFR 101.9 vs. 101.36
When designing your label artwork, pay close attention to these structural rule differences. The two panels below illustrate the contrasting layouts mandated by each regulation.
- Panel Title: Must read exactly "Nutrition Facts" or "Supplement Facts" — no variations permitted.
- Order of Nutrients:
- Nutrition Facts: Strictly limits nutrients to mandated core components (Calories, Fat, Sodium, Carbs, Sugars, Protein, Vitamin D, Calcium, Iron, Potassium). Non-RDI ingredients cannot be included inside the box.
- Supplement Facts: Allows (b)(2) dietary ingredients (nutrients with established DVs) at the top, separated by a heavy hairline from (b)(3) dietary ingredients (botanicals, aminos, herbs without established DVs) at the bottom.
- Proprietary Blends:
- Nutrition Facts: Not permitted. Every ingredient must be listed in the lower ingredient statement by weight.
- Supplement Facts: Permitted under 21 CFR 101.36(c). You can group herbs/actives under a single blend weight, listing individual components in descending order of predominance.
