Pea Protein Powder Labels Explained
A pea protein powder label is often short, sometimes a single ingredient, but it still holds a few lines worth reading closely: the exact protein wording, how much protein comes in how much powder, a sodium row that varies between brands, and a protein %DV that may not match the grams. This explainer reads pea protein powder labels line by line, using Naked Pea Protein, Unflavored as the worked example. For how pea compares with whey, casein and other powders as a type, see our whey isolate vs concentrate vs plant protein explainer.
How we wrote this: label details come from Naked Nutrition’s Nutrition Facts image for Naked Pea Unflavored, 1 lb, which shows the panel, the amino acid profile, the ingredient line and a testing mark, viewed in October 2026. That image does not show the rest of the bag, so we only report what it prints. The protein %DV rule comes from 21 CFR 101.9, and the Daily Values from the FDA page on the Daily Value on the Nutrition and Supplement Facts labels. Arithmetic marked as ours is simple division or multiplication of printed figures. We read labels; we did not test any product.
The short answer
Read the ingredient line and the product name together to see what kind of pea protein you are buying. Compare protein grams with the serving weight in grams, not with scoops. Check the sodium row, and expect the protein %DV to be lower than the grams alone would suggest. Count a testing mark only if it is printed on the label, and read free-from wording only as the label prints it.
Step 1: Pea protein isolate wording
Pea powders use a few names for the same source: pea protein, pea protein isolate, yellow pea protein, or organic pea protein. Our example is sold as Naked Pea Protein Isolate, while the ingredient line on the label reads simply “Yellow Pea Protein”.
That gap is common. The product name is the brand’s description, and the ingredient line is what the label lists. When you compare powders:
- Read the ingredient line first. It names the protein source the powder is made from.
- Read “isolate” in the name as the brand’s word. The panel tells you how much protein the powder carries; the name does not.
- Look for “organic” on the ingredient line itself if that matters to you, rather than only on the front.
Step 2: Protein per scoop vs scoop weight
The Naked Pea panel lists a serving size of 30 g (about 2 scoops) and 27 g of protein per serving. By our arithmetic, 27 g of protein in 30 g of powder is 90% protein by weight.
Two things follow from that serving line:
- One serving is two scoops here. Some powders use one scoop per serving, so “per scoop” and “per serving” are not always the same number. The label gives the serving in grams and in scoops, but not the weight of a single scoop.
- Grams are the figure to compare. Two powders with similar protein per serving can use very different serving weights. Compare protein per gram of powder as well as per serving.
The panel lists 15 servings per container. By our arithmetic, 15 servings of 30 g is 450 g. The image does not print a net weight; the product name says 1 lb, which is about 454 g by our conversion, so the two line up.
Step 3: The protein %DV and the PDCAAS rule
The FDA lists the Daily Value for protein as 50 g. By our arithmetic, 27 g is 54% of 50 g, but the Naked Pea panel lists protein at 36% DV.
The reason is the rule behind the protein %DV. Under 21 CFR 101.9, a protein %DV is based on the “corrected amount of protein per serving,” using the protein digestibility-corrected amino acid score (PDCAAS), while the grams line is the protein content by weight. So the grams and the %DV on a protein line measure different things, and a %DV lower than grams divided by 50 is what you would expect when the correction applies.
The label does not print a PDCAAS score, so we do not calculate one. When you compare powders, read the grams as the amount and the %DV as the corrected figure, and compare each with the same line on the other label.
Step 4: Sodium per serving and the other rows
Plant protein powders vary in sodium, so the sodium row is worth a look on every bag. The Naked Pea panel lists 110 mg of sodium per serving at 5% DV. The FDA lists the Daily Value for sodium as 2,300 mg; by our arithmetic, 110 mg is about 4.8% of that, which rounds to the 5% printed.
The same panel lists, per serving:
- 120 calories
- 0.5 g total fat (under 1% DV) and 0 g saturated fat
- 2 g total carbohydrate (1% DV), 0 g dietary fiber, 2 g total sugars and 0 g added sugars
- Iron 2.85 mg (16% DV), calcium 95 mg (7% DV) and potassium 100 mg (2% DV)
If you use more than one serving a day, multiply the sodium row by the servings you use, and add it to the sodium from your other foods if you track it.
Step 5: Single-ingredient vs blended
Some pea powders contain only pea protein. Others blend pea with other plant proteins, or add flavors, sweeteners, gums or salt. The ingredient line tells you which kind you have.
Naked Pea Unflavored is single-ingredient: the label lists “Yellow Pea Protein” and nothing else. In a blend, each protein is named in the ingredient list, but the label does not usually give the split between them, so the protein grams on the panel are for the blend as a whole.
Our egg white protein label guide reads a powder that adds amino acids to the ingredient line, for comparison.
Step 6: Testing marks and free-from wording
A testing mark counts if it is printed on the label. The Naked Pea image prints an NSF “Contents Certified” mark beside the panel. That is the mark the label shows; if you need a specific certification, check the exact product in NSF’s own listing.
Free-from and diet wording only counts as the label prints it. The image we read does not show “vegan”, “gluten free” or “non-GMO” wording, and it does not show an allergen statement or a facility line. Naked Nutrition describes the product with some of those words on its site, which makes them the brand’s description; check the printed bag for the wording and any facility statement before relying on it.
Talk to your doctor or pharmacist before adding a protein powder if you have a pea or legume allergy or a health condition, take medication, or are pregnant or nursing.
A quick checklist
- Ingredient line first, then the name.
- Protein grams against the serving weight in grams.
- Scoops per serving, and servings per container.
- Protein %DV: a corrected figure, so it can sit below grams divided by 50.
- Sodium per serving, multiplied by the servings you use.
- Testing marks and free-from wording only as printed.
FAQ
Why is 27 g of protein only 36% DV?
The protein %DV uses the corrected amount of protein under 21 CFR 101.9, while the grams line is the protein by weight.
Is pea protein isolate the same as yellow pea protein?
Our example uses both: “isolate” in the product name and “Yellow Pea Protein” on the ingredient line.
