If you want what Naked Nutrition sells, a protein powder with almost nothing in it, the closest swaps are Promix Nutrition, Transparent Labs, Ascent Protein and BulkSupplements. Each keeps a genuinely unflavored option and a short ingredient panel. The rest of this list covers goat, beef and plant versions of the same idea.
Most roundups that come up for this search are reviews of Naked itself, or general "clean protein" lists where Naked is one of the picks. That is not much help if you have already decided to buy something else.
So this page does something different. Naked's pitch is four specific things: a very short ingredient list, an unflavored version with no sweetener at all, sourcing you can name, and big bags sold direct. Every brand below is scored on those four, and where one of them drops a promise, the entry says so.
Why people look for an alternative
Price is the usual reason. A 5 lb bag of Naked Whey runs about $94.99 for 76 servings, which lands near $1.25 a serving, and shoppers who have bought it for years talk about the price climbing.
Testing is the second reason. After Consumer Reports tested a batch of protein powders for lead and flagged a couple of them, a lot of buyers stopped accepting "pure" as a claim and started asking to see numbers. Plant proteins made from pea, rice and hemp carry the most contamination risk, because the crops pull metals out of the soil they grow in.
Taste is the third. Unflavored whey tastes like unflavored whey. Some people want the short label and something they will actually drink.
How we picked these brands
- A short ingredient panel. One line is ideal. If the list runs longer than a sentence, it is not really replacing Naked.
- A real unflavored option you can buy today. We checked each brand's live product listings for an unflavored or unsweetened variant rather than trusting an old review. Two brands here do not have one, and we say which.
- Published testing. Third-party results, a sport certification, or a facility standard the brand names openly.
- Sourcing you can point at. Grass-fed, native, organic, goat, beef. A country or a farming standard beats an adjective.
- Price per serving and bulk sizing. A purity story that only comes in a 1 lb tub costs a fortune to actually use.
Every brand here sells direct from its own store, which matters more than it sounds. Buying from the source means the ingredient panel, the batch, and the testing all come from one place. It is the same reason our roundup of direct-to-consumer supplement brands leans the way it does.

1. Promix Nutrition
If you want the nearest thing to a like-for-like swap, start with Promix Nutrition. Its Unflavored Whey Protein Powder is native grass-fed whey, unsweetened, at 25g of protein and 5.9g of BCAAs per serving, and the brand describes it as minimally filtered so it keeps its omega-3s and CLA.
There is also an unflavored grass-fed beef protein isolate if you are moving off dairy but not off animal protein.
Best for the unflavored purist who wants the same product in a different bag. All four promises intact.
2. Transparent Labs
Transparent Labs built its name on publishing what is in the tub, and its Grass-Fed Whey Protein Isolate is sold in an Unflavored variant next to the flavored ones, so you can pick either without changing brands.
It is the most commonly recommended Naked substitute in the review press, appearing in four of the five competing roundups we read.
Best for the shopper who wants documentation rather than adjectives. If you like this brand's approach, we compared it with nine others in our guide to brands like Transparent Labs.
3. Ascent Protein
Ascent Protein uses native whey, which is filtered straight from milk rather than collected as a cheese-making byproduct. The Unflavored Protein Powder gives 25g per serving and comes in 2 lb and 4 lb bags.
The sticker price sits below most of the premium set, which makes it the easiest first swap if cost is what pushed you off Naked in the first place.
Best for someone who wants the purity story without the premium tier price.
4. Mt. Capra
Mt. Capra makes its protein from goat milk instead of cow milk, which is a real fix rather than a marketing angle if cow whey leaves you bloated. Clean Whey Protein comes in an Unsweetened variant in both 1 lb and 5 lb.
Goat whey is a different protein structure, and plenty of people who react to standard whey concentrate do fine with it.
Best for the person whose stomach has already told them cow dairy is the problem.
5. Momentous
Momentous sources its Whey Protein Isolate from European dairy farms, from cows raised without hormones, steroids or rBST, then cold-processes and micro-filters it to keep the amino acid profile intact. There is an Unflavored variant, at 20g per serving.
It is priced at the top of the range, and the brand leans hard into athlete use.
Best for someone who wants to know the farm standard, not just the phrase "grass-fed" on a bag.
6. Equip Foods
Equip Foods makes Prime Protein from grass-fed beef rather than dairy, at 21g of complete protein per scoop, with what the brand calls a handful of carefully sourced real-food ingredients.
Beef protein isolate is a genuinely different route out of dairy, and it is complete protein, which most plant options are not without blending.
Best for anyone leaving dairy entirely who does not want to switch to a plant blend. Note that it is sold flavored, so this is a swap for the ingredient philosophy rather than for the unflavored bag.
7. Bare Performance Nutrition
Bare Performance Nutrition uses Truly Grass Fed Irish whey for its Grass-Fed Whey Protein Isolate, 95% grass fed, 25g per serving, with the lactose largely filtered out.
Isolate with minimal lactose is the usual answer for people who blame whey for their digestion when the actual culprit is the milk sugar riding along with it.
Best for a sensitive stomach that still wants dairy whey. It ships in Vanilla and Fudge Chocolate only, so there is no unflavored bag here.
8. Ora Organic
Ora Organic is the plant option that keeps the unflavored promise. So Lean & So Clean is an organic plant protein sold in an Unsweetened and Unflavored variant, made without artificial sweeteners, fillers or gums, and it was developed by a chef rather than a lab.
If you are going plant-based mainly because you want a simpler product, check that the brand publishes heavy-metal testing, since pea and rice proteins carry more soil-contamination risk than dairy does.
Best for plant-based buyers who still want a bag with nothing added.
9. Kion
Kion sells one protein, Clean Protein, a grass-fed and pasture-raised whey isolate, and its variant list includes a Purely Unflavored option alongside Smooth Vanilla and Rich Chocolate. The flavored versions use organic natural flavors.
A single-SKU catalogue is a small thing that tells you something. There is no third protein to upsell you into.
Best for someone who wants one good option and no decision tree.
10. Xwerks
Xwerks makes Grow from 100% New Zealand grass-fed whey protein isolate, micro-filtered, from cows grazing under one of the stricter national dairy standards in the world.
Sourcing is the whole argument here, and it is a specific one you can check rather than a vague claim about quality.
Best for buyers who care most about where the milk came from. Grow ships in four flavors with no unflavored version, so it swaps the sourcing promise but not the plain-bag one.
11. BulkSupplements
BulkSupplements sells single-ingredient powders by weight, which is about as close to Naked's philosophy as the category gets. Its Grass-Fed Whey Protein Concentrate runs from a 100g sample through 250g, 500g, 1kg and up to a 5kg bag, with the 1kg listed at $46.97.
Buying a 100g pouch first is genuinely useful when you have already been burned by a 5 lb bag you did not like.
Best for the price-per-gram buyer, and for anyone who wants to taste-test before committing to bulk.
12. Nutricost
Nutricost is the budget end of this list. Its Whey Protein Isolate delivers 30g of protein per serving, is made in a GMP compliant and FDA registered facility, and sells Unflavored in both 2 lb and 5 lb.
The label is plainer than the premium brands and the sourcing story is thinner, but the unflavored bulk bag is the point.
Best for the shopper who wants unflavored isolate at the lowest sticker price and is not paying extra for a sourcing narrative.
How to choose your replacement
Work backwards from which of Naked's four promises you actually cared about.
If it was the single-ingredient unflavored bag, go to Promix Nutrition, Ascent Protein or Nutricost. All three sell an unflavored whey today, at three different price points.
If it was the price, BulkSupplements and Nutricost are the two real budget answers, and BulkSupplements lets you buy 100g before you commit to a kilo.
If it was the testing and transparency, Transparent Labs and Momentous publish the most about what they make and where it comes from.
If dairy is the problem, split by cause. Cow milk specifically, try Mt. Capra's goat protein. Lactose, try an isolate like BPN. Dairy full stop, try Equip Foods for beef or Ora Organic for plants.
If you want a short label and a flavor worth drinking, Kion and Xwerks are the two that keep the sourcing tight without asking you to drink plain whey.
One thing worth checking before you buy: the price per serving, not the price on the bag. A 1 lb tub and a 5 lb bag from the same brand can differ by nearly a dollar a scoop. We do the same maths across the wider category in our protein powder brand roundup, and the same logic applies if you are shopping meal-replacement shakes rather than straight protein, where we compared the alternatives to Ka'Chava.
Frequently asked questions
Why do people look for Naked Nutrition alternatives?
Mostly price. A 5 lb bag of Naked Whey lands around $1.25 per serving, and longtime buyers report it creeping up. The other two reasons are wanting published third-party testing and wanting a non-dairy base.
Is there a cheaper protein powder that is still single-ingredient?
Yes. BulkSupplements sells grass-fed whey concentrate by weight, with a 1kg bag listed at $46.97, and Nutricost sells unflavored isolate in 2 lb and 5 lb. Both trade the branding for the price.
Which alternatives have a genuinely unflavored option?
Promix Nutrition, Transparent Labs, Ascent Protein, Mt. Capra, Momentous, Ora Organic, Kion and Nutricost all list an unflavored or unsweetened variant. BPN, Xwerks and Equip Foods do not, so treat those as philosophy swaps rather than plain-bag swaps.
What should I look for instead of a "clean" label?
Read the ingredient panel and the testing. "Clean" is not a regulated term, so the useful signals are a short panel, a named source such as native whey or New Zealand dairy, and results the brand publishes rather than describes.
Are plant proteins more likely to contain heavy metals?
They carry more risk than dairy, yes. Pea, rice and hemp crops take up metals from the soil they grow in, so plant powders are the ones where published heavy-metal testing is worth insisting on.
Is whey isolate better than concentrate for a sensitive stomach?
Often. Isolate has most of the lactose filtered out, and lactose is what bothers a lot of people who assume whey itself is the issue. Concentrate keeps a little more of the milk fat and lactose, and costs less.
What is native whey and does it matter?
Native whey is filtered directly from milk rather than left over from cheese production. Ascent Protein and Promix Nutrition both use it. It is a gentler process, and whether you notice the difference is a fair question, but it is a real distinction rather than a marketing one.
