Egg White Protein Powder Labels Explained
An egg white protein powder label looks short, but it answers several questions: what form the egg is in, how much protein a scoop carries compared with the scoop’s weight, what else is mixed in, and what the allergen line says. This explainer reads egg white protein powder labels line by line, using NOW Sports Egg White Protein, Unflavored as the worked example. For how egg white compares with whey, casein and plant powders as a type, see our whey isolate vs concentrate vs plant protein explainer.
How we wrote this: label details come from the NIH Dietary Supplement Label Database record 335346 for NOW Sports Egg White Protein with BCAAs, Unflavored, entered in 2025, read in October 2026. That record is for the 5 lb size; we did not have the label for the 1.2 lb size, so where the sizes could differ we say so. Allergen background comes from the FDA page on the Food Allergen Labeling and Consumer Protection Act of 2004 (FALCPA). The protein Daily Value comes from the FDA page on the Daily Value on the Nutrition and Supplement Facts labels. Arithmetic marked as ours is simple division or subtraction. We read labels; we did not test any product.
The short answer
Read the ingredient line to see what form the egg is in and what has been added. Compare grams of protein with the serving weight, and remember a cup measure is not a weight. Check the allergen statement, the flavor and sweetener lines, and count a testing seal only if it is printed on the label.
Step 1: Egg white powder vs egg protein wording
The ingredient line names the protein source. The NOW Sports label lists “Egg White, Powder” at 18.75 g per serving. Other egg powders may use different words in the same place, such as dried egg whites, egg white protein or whole egg. Read that word on every label you compare; it is the one that tells you which part of the egg the powder is built on. Our pea protein label guide reads the same line on a plant powder.
The label also says the egg white powder is pasteurized. That is the brand’s statement on the label about how the ingredient was handled, and the label does not give the method.
Step 2: Protein per scoop vs scoop weight
The NOW Sports label lists a serving size of 1/4 cup (20 g) and 15 g of protein per serving. By our arithmetic, 15 g of protein in 20 g of powder is 75% protein by weight.
Two points matter when you compare:
- Compare grams, not cups or scoops. One powder’s 1/4 cup and another’s scoop can weigh different amounts. Compare protein per gram of powder as well as per serving.
- A cup is volume. The label says the product is sold by weight, not volume. A cup of powder can settle or pack down, so the 20 g on the panel is the figure to rely on. A kitchen scale will show whether your 1/4 cup matches it.
The 5 lb label lists 113 servings per container and a net weight of 5 lb (2,268 g). By our arithmetic, 2,268 g divided by 20 g is about 113 servings, which matches. We did not have the 1.2 lb label, so we do not give its servings count; divide its net weight in grams by 20 g to estimate it.
Step 3: The protein %DV
The FDA lists the Daily Value for protein as 50 g. The NOW Sports label lists 15 g of protein at 30% DV. By our arithmetic, 15 g is 30% of 50 g.
The label carries a brand statement about protein quality that refers to PDCAAS. That is the brand’s statement, not a figure on the panel, and the label does not print a PDCAAS score. Our casein protein label guide explains what the corrected protein %DV rule says.
Step 4: Added BCAAs and lecithin in the ingredient line
Many egg powders list only egg white. This one adds two things, and the label shows both:
- BCAAs: the label lists branched-chain amino acids, powder, at 1 g per serving, as L-isoleucine, L-leucine and L-valine.
- Lecithin: sunflower lecithin appears under other ingredients, with no amount given.
Step 5: The egg allergen statement
FALCPA is the federal law behind food allergen labeling. The FDA page that sets out the Act names eggs among the major foods that account for most food allergies, alongside milk, fish, crustacean shellfish, tree nuts, peanuts, wheat and soybeans.
The NOW Sports label says “Contains egg.” It also says the product is not manufactured with wheat, gluten, soy, milk, fish, shellfish, tree nut or sesame ingredients, and that it is produced in a GMP facility that processes other ingredients containing these allergens. Read both lines together: “not manufactured with” describes the recipe, and the facility line tells you what else is handled where it is made.
If you avoid milk, that facility line is the one to weigh. The label does not say “dairy free”; it says the product is not made with milk ingredients, in a facility that processes them.
Step 6: Unflavored vs flavored
This product is unflavored, and its ingredient line has no flavor or sweetener. The label also says “No aspartame, No sucralose, No acesulfame-K” and that natural color variation may occur.
The label’s directions are to mix 1/4 cup daily into 12 oz of milk or another liquid. It also gives a cooking swap: two tablespoons of powder with six tablespoons of water to equal two egg whites.
Step 7: Seals, statements and the disclaimer
A testing mark counts if it is printed on the label. The NOW Sports label record lists these seals and symbols: Informed Sport (“We test, You trust”), Triangle K (kosher), Crescent H (halal), GMP Quality Assured and “Steroid tested”. So the Informed Sport mark is printed on this label. If you need a certified product, check the exact size and flavor in the certifier’s own directory.
The label is a Supplement Facts label; its statement of identity is “A Dietary Supplement”. It also carries a notice: use this product as a food supplement only, and do not use it for weight reduction. Brand statements on a supplement label come with the FDA disclaimer, as at the end of this page.
Talk to your doctor or pharmacist before adding a protein powder if you have an egg allergy or a health condition, take medication, or are pregnant or nursing.
A quick checklist
- Ingredient line: which form of egg, and what has been added.
- Protein grams against the serving weight in grams.
- Servings per container, by net weight divided by serving weight.
- Added BCAAs or lecithin, with amounts if given.
- “Contains egg” plus any facility statement.
- Seals printed on the label.
FAQ
Why does 15 g of protein show as 30% DV?
The FDA Daily Value for protein is 50 g, and 15 g is 30% of that, by our arithmetic.
