Supplement Facts vs Nutrition Facts

The Core Distinction: Food vs. Supplement

The fundamental difference is what the label describes. Nutrition Facts labels (21 CFR 101.9) are for conventional foods and beverages: anything you eat or drink for nutrition, taste, or enjoyment. Supplement Facts labels (21 CFR 101.36) are for dietary supplements: products intended to add nutritional value to the diet, including vitamins, minerals, herbs, amino acids, and other botanicals.

This distinction matters because the FDA regulates these two categories under entirely different frameworks. A protein bar gets a Nutrition Facts label. A vitamin D capsule gets a Supplement Facts label. The rules, formatting, and allowed claims differ substantially.

Regulatory Framework Differences

Nutrition Facts labels are governed by 21 CFR 101.9, which specifies 15 mandatory nutrients, 5 label formats (vertical, tabular, linear, dual-column, simplified), and detailed rounding rules for every nutrient. The Daily Values used are based on a 2,000-calorie reference diet for adults and children 4+ years.

Supplement Facts labels are governed by 21 CFR 101.36, which defines 6 population-specific Daily Value groups: adults and children 4+ years, children 1-3 years, children 4-8 years (separate from the adult table), pregnant women, lactating women, and infants. A supplement label must use the DV appropriate for its target population.

The Supplement Facts regulation allows for nutrients that have no established Daily Value (marked as "Daily Value not established"), proprietary blend formatting (listing total blend weight without individual component weights), and different rules for the ordering of dietary ingredients.

Proprietary Blends: A Supplement-Only Feature

One of the most visible differences is the proprietary blend. Under 21 CFR 101.36(c)(2), dietary supplement manufacturers can list a blend of ingredients as a single "Proprietary Blend" with only the total weight of the blend. Individual component amounts are not required. The components must be listed in descending order of predominance by weight.

Nutrition Facts labels have no equivalent. Every ingredient in a conventional food must be listed in the ingredient statement in descending order of weight. There is no mechanism to hide individual amounts behind a blend designation.

Population-Specific Daily Values

Supplement Facts labels support six population groups, each with different Daily Values for many nutrients:

• Adults and Children 4+ Years: The reference group used for most supplements
• Children 1-3 Years: Lower DVs reflecting a child's smaller body and different nutritional needs
• Children 4-8 Years: A separate group with values between the 1-3 and adult ranges
• Pregnant Women: Higher DVs for nutrients like iron, folate, and calcium
• Lactating Women: Adjusted DVs reflecting the nutritional demands of breastfeeding
• Infants: The lowest DVs, designed for children under 1 year

Nutrition Facts labels, in contrast, use a single set of Daily Values for ages 4+. Separate labeling for foods intended for children under 4 follows different rules entirely.

Which Label Does Your Product Need?

If your product is a conventional food or beverage (snack bar, sauce, drink, baked good, frozen meal), you need a Nutrition Facts label per 21 CFR 101.9.

If your product is a dietary supplement (vitamin tablet, mineral capsule, herbal extract, protein powder marketed as a supplement, fish oil softgel, probiotic), you need a Supplement Facts label per 21 CFR 101.36.

The distinction is not always obvious. Protein powders can be labeled as either, depending on marketing and intended use. When in doubt, consult with an FDA labeling specialist or use NutriSpec's label generator, which selects the correct format based on your product type.

Frequently Asked Questions

Can I use a Nutrition Facts label for my supplement?

No. The FDA requires dietary supplements to use the Supplement Facts format per 21 CFR 101.36. Using a Nutrition Facts label on a supplement would make your product misbranded under federal law.

What are the mandatory nutrients on a Supplement Facts label?

Supplement Facts labels must list total calories, calories from fat, total fat, saturated fat, trans fat, cholesterol, sodium, total carbohydrate, dietary fiber, total sugars, added sugars, protein, vitamin D, calcium, iron, and potassium, but only if present in measurable amounts. Nutrients present at zero or trace levels can (and should) be omitted, unlike Nutrition Facts where they must be declared as zero.

Does NutriSpec support both label types?

Yes. NutriSpec generates both Nutrition Facts (21 CFR 101.9) and Supplement Facts (21 CFR 101.36) labels. It also supports CFIA (Canada), EU FIC, GB 28050 (China), and Infant Formula labels.
