Unflavored Naked Whey, NOW Sports Whey Protein Isolate Unflavored, and unflavored Naked Pea are three protein powders whose manufacturer ingredient lists did not include sucralose when checked on September 10, 2026. None of those specific statements listed another added sweetener either.
That makes them useful starting points if you want control over the sweetness of a shake. It does not make them nutritionally identical. Two contain milk protein; one is pea protein. One includes sunflower lecithin. A powder that meets your sweetener preference may still miss your protein-source, allergen, or texture requirements.
This is a U.S.-focused ingredient comparison, not a workout prescription or laboratory assessment. We checked official product information, not taste, mixing performance, contaminant levels, or muscle-building outcomes. The named versions matter: a brand can sell unflavored, vanilla, chocolate, and shake blends with different ingredients under a similar design.
Naked Whey: A Single-Ingredient Milk-Based Option
The unflavored Naked Whey page identifies one ingredient: grass-fed whey protein. It also states that no artificial sweeteners are added. For the narrow question “does this version list sucralose?”, those are relevant pieces of evidence.
Do not transfer the finding to every product that starts with “Naked.” A flavored version, a mass-gainer blend, and an unflavored whey tub are separate recipes. Even reviews on the same product page may mention several flavors, so a review describing sweetness does not establish the selected version's ingredients.
Choose this category when you want a milk-based powder without an added sweetener and plan to control the rest of the drink yourself. If milk is an exclusion, stop at the word whey. “Grass-fed” describes sourcing; it does not turn a milk protein into a dairy-free food.
We have not used the manufacturer's broader health or purity language as a ranking system. A simple ingredient statement is easy to audit for sucralose, but it is not a substitute for product-specific evidence about anything else you care about.
NOW Sports Unflavored Isolate: Notice the Lecithin
NOW's ingredient statement lists whey protein isolate and sunflower lecithin at less than 1%, followed by “Contains milk.” The product also displays a no-sucralose statement.
This entry shows why “without sucralose” is not the same as “one ingredient.” Sunflower lecithin is a separate ingredient, not a sweetener. If your preference is specifically to avoid sucralose, its presence does not contradict that filter. If you also avoid lecithin, this is not a match for that second rule.
The manufacturer states that the product is made in a facility processing other ingredients containing allergens. That is separate from the declared milk ingredient. Read both parts if food allergy is relevant, rather than interpreting a short ingredient list as complete information about the production environment.
For the difference between isolate and concentrate, use our protein processing comparison. This buying guide does not assume that isolate is automatically the right choice for every person or use.
Naked Pea: A Plant-Based, Unflavored Alternative
Naked Pea's unflavored page identifies yellow pea protein as its one ingredient. It provides a non-whey route for someone whose shopping rule includes avoiding dairy ingredients as well as sucralose.
That is a source distinction, not a promise of equivalent flavor or texture. We did not conduct a side-by-side shake test. If you are moving from a heavily flavored powder, first decide whether you want an unsweetened base or a ready-flavored drink. Those are different expectations, even when both products meet the same exclusion.
Pea protein is not automatically appropriate for every person with food allergies. If you have a relevant allergy history, follow your established guidance; our pea protein and peanut allergy article explains why the label cannot settle every question.
The same product page offers other flavors. Select unflavored before comparing the statement, and verify the tub you receive. A photograph of peas beside a vanilla shake does not tell you whether the powder itself includes a sweetener.
Compare the Whole Shake, Not Just the Powder
A powder without sucralose can end up in a shake that contains it if the mixer, syrup, or another supplement adds it. Check ready-to-drink milk alternatives, flavored drink bases, and any powder you combine in the same shaker.
Conversely, adding fruit or a sweetener yourself does not change the original powder's ingredient statement. It changes the finished drink. Keep those two records separate if you are trying to identify what suits your preferences: what came in the tub, and what you added.
Use a consistent amount when comparing two products for personal taste. Scoops are not standardized across brands. A level scoop of one powder need not weigh the same as a level scoop of another. Read the serving weight and protein amount instead of comparing the word “scoop.”
If cost matters, compare the same kind of purchase: one-time versus subscription, similar package weights, and shipping included. A headline tub price is not enough. We have not published a price ranking because promotions and stock can change without an ingredient update.
What a Verified Ingredient List Does Not Prove
“Verified” here means checked against the named manufacturer's published statement on the stated date. It does not mean we tested the powder, independently certified it, or confirmed every batch.
A sucralose check cannot measure heavy metals, verify sports-certification status, predict digestive tolerance, or establish whether a serving meets your needs. If one of those is part of your purchase decision, seek evidence specifically about that question. A short list should not be used as a shortcut around missing information.
For allergens, the FDA explains the distinction between ingredient declarations and voluntary advisory statements. Absence of a “may contain” sentence is not proof of a dedicated facility. For these products, whey itself already establishes a milk ingredient regardless of any advisory wording.
