Good source and high-in claims.

What 101.54 covers

Section 101.54 governs claims about the level of a nutrient in relation to the Reference Daily Intake (RDI) in 101.9(c)(8)(iv) or the Daily Reference Value (DRV) in 101.9(c)(9), excluding total carbohydrates. Paragraph (a) allows such a claim only if it uses a term defined in the section in accordance with its definition, follows the general requirements in 101.13, and the food is labeled in accordance with 101.9, 101.10 or 101.36. The text here is the eCFR version current through October 29, 2026.

High and good source: paragraphs (b) and (c)

For meal products and main dish products (defined in 101.13(l) and (m)) the same terms may be used if the product contains a food that meets the definition and the label clearly identifies that food, for example "the serving of broccoli in this product is high in vitamin C" (b)(2) or "the serving of sweet potatoes in this product is a good source of fiber" (c)(2).

Fiber claims and fat disclosure: paragraph (d)

If a claim says a product is high in fiber, a good source of fiber, or contains "more" fiber, and the food is not "low" in total fat as defined in 101.62(b)(2) (or for meal and main dish products, 101.62(b)(3)), the label must disclose the level of total fat per labeled serving. The disclosure must appear in immediate proximity to the claim, in type no less than one-half the size of the claim, and precede any 101.13(h) disclosure statement, for example "contains [x amount] of total fat per serving. See nutrition information for fat content."

More, fortified, enriched: paragraph (e)

A relative claim using "more," "fortified," "enriched," "added," "extra" or "plus" may describe the level of protein, vitamins, minerals, dietary fiber or potassium if three conditions hold:

• The food contains at least 10 percent more of the RDI (vitamins or minerals) or the DRV (protein, dietary fiber, potassium), expressed as a percent of the Daily Value, per reference amount than an appropriate reference food (e)(1)(i). Meal and main dish products use the same 10 percent test per 100 g (e)(2).
• Where the claim rests on an added nutrient, the fortification must be in accordance with the policy in 104.20 (e)(1)(ii).
• The reference food and the percentage difference are declared in immediate proximity to the most prominent claim, for example "contains 10 percent more of the Daily Value for fiber than white bread," with quantitative comparison information next to the claim or the nutrition label (e)(1)(iii).

High potency and antioxidant: paragraphs (f) and (g)

• High potency (f): may describe individual vitamins or minerals present at 100 percent or more of the RDI per reference amount, with the nutrient clearly identified if other nutrients are present; and may describe a multi-ingredient product with 100 percent or more of the RDI for at least two-thirds of the vitamins and minerals listed in 101.9(c)(8)(iv) that are present at 2 percent or more of the RDI.
• Antioxidant (g): allowed when an RDI exists for each nutrient, the nutrients have recognized antioxidant activity, the level of each qualifies for a (b), (c) or (e) claim (for example 20 percent or more of the RDI for vitamin C for "high in antioxidant vitamin C"), and the names of the nutrients are part of the claim or linked by a symbol to a list in type no smaller than the larger of one-half of the largest claim or 1/16 inch.

Worked example

A cereal supplies 15 percent of the Daily Value for fiber per reference amount. That sits in the 10 to 19 percent band of (c)(1), so "good source of fiber" is the defined term that fits, and because it is a fiber claim the total fat disclosure in (d) applies unless the food is low fat. At 22 percent it moves to the (b)(1) high tier. For a "more fiber" claim against a reference food at 5 percent, a 15 percent product is 10 percentage points higher, which reaches the (e)(1)(i) test, though the reference food and the percent would also have to be declared. The checker above applies only the percent comparisons.

What the numbers do not decide

The text says "10 to 19 percent" and "20 percent or more." Whether a value such as 19.6 percent is rounded for the label before it is compared is a labeling question the checker does not answer; it treats anything from 10 up to but not including 20 as the good source band. The nutrient must also be one for which an RDI or DRV exists, and the page gives no nutrition advice.
