Nutritional Yeast Labels: Fortified vs Unfortified, B Vitamins and %DV
Nutritional yeast is sold in shaker bottles, bags and bulk bins, and the labels look alike from the front. The back is where they differ: whether vitamins were added, how big the serving is, and how the %DV column was worked out. This guide reads one real label line by line, Bragg Premium Nutritional Yeast Seasoning, and shows what to check on any other bottle or bag.
A quick note first: this is a label guide, not advice on what to eat. We do not say whether one serving covers anyone’s needs for any vitamin. Talk to your doctor or pharmacist if you have questions about B vitamins, folic acid or B12, especially if you take medication.
What the name tells you
Bragg’s product page describes nutritional yeast as “an inactivated version of the yeast often used to make bread or beer” with “a savory or umami flavor” (Bragg). That is the brand’s own description, and it is the only definition we use here.
Shoppers often meet three names on the shelf: nutritional yeast, brewer’s yeast and baking yeast such as active dry yeast. Each is a separate product with its own name, directions and label, and we read only the Bragg label in this guide. The practical step is simple: read the product name and the ingredient line, and do not assume one can stand in for another just because the word yeast appears on both. A baking yeast packet is sold for dough; the Bragg bottle is sold as a seasoning, with directions to sprinkle it over salads, vegetables, pasta, rice and popcorn, or to use it “as a substitute for grated cheese” (Bragg).
Fortified or unfortified: read the ingredient line
The quickest way to tell whether vitamins were added is the ingredient line, not the front of the pack. On the Bragg page it reads:
“Dried Yeast, Niacin (Vitamin B3), Pyridoxine Hydrochloride (Vitamin B6), Thiamin Hydrochloride (Vitamin B1), Riboflavin (Vitamin B2), Folic Acid (Vitamin B9), Cyanocobalamin (Vitamin B12)” (Bragg).
Six vitamins are named after the yeast itself, so this is a fortified product: those B vitamins were added as ingredients. An unfortified nutritional yeast would list only the yeast, and its panel would show whatever the yeast contains on its own. If a bag says only “nutritional yeast” in the ingredient line, do not expect the same B vitamin figures as a fortified bottle; read its own panel.
Two more lines appear on the Bragg panel: iron 1mg (6% DV) and potassium 214mg (4% DV). Neither is named in the ingredient line, so they are not listed as added ingredients.
Bragg describes the bottle as having “6 B vitamins,” which matches the six vitamins named in the ingredient line (Bragg).
The serving size: 2 tablespoons, not 1
Bragg prints a serving size of 2 tbsp with 12 servings per container for the 4.5 oz bottle (Bragg). Many recipes and shakers work in teaspoons or single tablespoons, so check the serving before you read any number below it. Every figure on the panel is per 2 tbsp. By our arithmetic, a single tablespoon would carry half of each printed amount, for example 7.5 mcg of B12 instead of 15 mcg.
Per 2 tbsp serving, the Bragg panel lists (Bragg):
- Total fat 0g (0% DV)
- Sodium 20mg (1% DV)
- Total carbohydrate 3g (1% DV)
- Dietary fiber 2g (7% DV)
- Protein 5g (11% DV)
- Iron 1mg (6% DV) and potassium 214mg (4% DV)
By our arithmetic, 12 servings of 5 g of protein comes to 60 g of protein per bottle.
The B vitamin lines and their %DV
This is the part of the panel that makes nutritional yeast labels look unusual. Per 2 tbsp, Bragg prints (Bragg):
| Vitamin | Amount per serving | %DV as printed | FDA Daily Value (adults and children 4+) |
|---|---|---|---|
| Thiamin (B1) | 6.2mg | 520% | 1.2 mg |
| Riboflavin (B2) | 6.3mg | 480% | 1.3 mg |
| Niacin (B3) | 35mg | 220% | 16 mg NE |
| Vitamin B6 | 7.2mg | 420% | 1.7 mg |
| Folate (B9) | 353mcg DFE | 90% | 400 mcg DFE |
| Vitamin B12 | 15mcg | 630% | 2.4 mcg |
The Daily Values in the last column come from the FDA nutrition labeling rule, 21 CFR 101.9, which sets the reference amounts a label divides by. By our arithmetic, 15 mcg divided by 2.4 mcg is 625%, and the label prints 630%; 6.2 mg divided by 1.2 mg is about 517%, and the label prints 520%; 35 mg divided by 16 mg is about 219%, and the label prints 220%. The printed figures sit within a few points of the plain division in every row we checked, which is what you would expect from rounding.
Two practical points. First, a %DV over 100 is simply the printed amount compared with the Daily Value; the label does not tell you what that means for you, and we do not either. Second, folate is shown in mcg DFE (dietary folate equivalents), the unit 21 CFR 101.9 uses for folate, so compare it with other labels in the same unit. For how B12 is printed on a supplement bottle instead of a food panel, see our vitamin B12 label guide.
By our arithmetic, 12 servings of 15 mcg comes to 180 mcg of B12 per bottle.
What FDA’s fortification policy says
FDA’s fortification policy is in 21 CFR 104.20. Its stated objective is “to establish a uniform set of principles that will serve as a model for the rational addition of nutrients to foods.” The same section says FDA “does not encourage indiscriminate addition of nutrients to foods,” and that manufacturers who choose to fortify “are urged to utilize these principles.” In other words, the section is written as a set of guiding principles that makers are urged to follow. It does not, in the passage we quote, list nutritional yeast or set amounts for it, so we do not read anything about this product into it.
Nutrition Facts, not Supplement Facts
The Bragg bottle carries a Nutrition Facts panel, the panel used on conventional foods, even though its vitamin percentages look like the numbers you might see on a supplement. Our guide to the Nutrition Facts label covers the layout line by line, and our supplement label guide covers the Supplement Facts panel for comparison.
Vegan, gluten-free and other marks
Bragg’s product page lists these marks in its own words: “Vegan,” “5g vegan protein per serving,” “No artificial color or flavors,” “Gluten-free,” “Keto-friendly” and “No dairy.” (Bragg). These are the brand’s statements. The product page we read did not show a kosher mark or a Non-GMO mark for this item, so we do not list either. For other plant-based pantry items and how we check vegan claims, see our vegan snacks and pantry staples list.
A quick checklist
- Read the ingredient line: added vitamins named there mean the product is fortified.
- Check the serving size before any number; Bragg’s is 2 tbsp.
- Compare %DV only with labels that use the same serving and the same units (mcg DFE for folate).
- Read the marks as the brand’s own words unless a certifier is named.
- Ask your doctor or pharmacist about vitamin amounts for you.
FAQ
Is Bragg nutritional yeast fortified?
Yes. Its ingredient line names niacin, pyridoxine hydrochloride, thiamin hydrochloride, riboflavin, folic acid and cyanocobalamin after the dried yeast (Bragg).
How much B12 is in a serving?
The panel lists 15mcg (630% DV) per 2 tbsp serving. By our arithmetic, 1 tbsp would be 7.5 mcg.
Is nutritional yeast the same as brewer’s yeast or baking yeast?
They are sold as separate products with separate labels. Bragg describes its nutritional yeast as an inactivated version of the yeast often used for bread or beer; read each product’s own name and ingredient line.
Why is the %DV over 100?
The %DV compares the printed amount with the FDA Daily Value in 21 CFR 101.9. When the amount is larger than the Daily Value, the figure goes over 100.
