About Nutrition Label Generator
The Nutrition Facts Label Generator creates FDA-style nutrition information panels from user-entered nutritional data. Enter values for 10 nutrients — total fat, saturated fat, trans fat, cholesterol, sodium, total carbohydrates, dietary fiber, total sugars, added sugars, and protein — along with serving size, servings per container, and calories to generate a properly formatted nutrition facts label.
The tool automatically calculates % Daily Value (DV) for 8 nutrients using the FDA 2,000-calorie reference diet: total fat (78g DV), saturated fat (20g DV), cholesterol (300mg DV), sodium (2,300mg DV), total carbohydrates (275g DV), dietary fiber (28g DV), added sugars (50g DV), and protein (50g DV). Trans fat and total sugars are displayed without %DV as per FDA guidelines.
A calorie breakdown section calculates calories from fat (fat grams x 9), calories from carbohydrates (carb grams x 4), and calories from protein (protein grams x 4) using the Atwater energy factors. All calculations update in real time as you type, and the entire tool runs client-side with no data transmitted to any server.

Frequently Asked Questions
What Daily Value (DV) reference amounts does the generator use?
The generator uses FDA standard daily values based on a 2,000-calorie diet: total fat 78g, saturated fat 20g, cholesterol 300mg, sodium 2,300mg, total carbohydrates 275g, dietary fiber 28g, added sugars 50g, and protein 50g. For example, if you enter 12g of total fat, the %DV shown is 12/78 x 100 = 15%.
Why do trans fat and total sugars not show a % Daily Value?
Per FDA nutrition labeling regulations, trans fat and total sugars do not have established daily reference values and therefore are not displayed with %DV on the nutrition facts panel. However, added sugars (a subset of total sugars) do have a 50g daily value and show a %DV. Trans fat is listed as a sub-item under total fat without a percentage.
How are the calorie breakdown values calculated?
The calorie breakdown uses the Atwater energy factor system: fat provides 9 calories per gram, carbohydrates provide 4 calories per gram, and protein provides 4 calories per gram. For example, 12g of total fat = 108 calories from fat, 31g of carbs = 124 calories from carbs, and 5g of protein = 20 calories from protein.
Can I customize the serving size unit?
Yes. The serving size field accepts both a numeric value and a customizable unit text field. You can enter any unit such as g, mL, oz, cups, pieces, or slices. The label will display the serving size exactly as entered, for example "240mL" or "30g" or "2 pieces".
Does the generated label follow official FDA formatting?
The label follows the visual style of the FDA Nutrition Facts format with the bold "Nutrition Facts" header, 8px thick bottom border, calorie display in large bold text, %Daily Value column aligned to the right, indented sub-nutrients (saturated fat, trans fat, fiber, sugars), and the standard footnote about the 2,000-calorie reference diet. However, for official product labeling, always verify compliance with current FDA Title 21 CFR 101.9 requirements.
How is the % Daily Value percentage calculated?
The %DV is calculated as (nutrient amount per serving / daily reference value) x 100, rounded to the nearest whole number. For example, 470mg sodium with a 2,300mg daily value = (470/2300) x 100 = 20%. This tells consumers that one serving provides 20% of their recommended daily sodium intake based on a 2,000-calorie diet.
What nutrients are shown as indented sub-items on the label?
Five nutrients are displayed as indented sub-items: saturated fat and trans fat appear indented under total fat, while dietary fiber, total sugars, and added sugars (marked as "Incl. Added Sugars") appear indented under total carbohydrate. This visual hierarchy follows FDA label formatting conventions to show parent-child nutrient relationships.
Is my nutritional data stored or transmitted anywhere?
No. All calculations happen entirely in your browser using React state management and the useMemo hook. Nutrient values, serving sizes, and calculated percentages are processed client-side in real time. No data is ever sent to a server, stored in a database, or shared with any third party.
