Our verdict

Naked Whey is the simplest way to add whey to your diet: one ingredient, 25 g of protein per serving and a fair price for grass-fed sourcing. It tastes plain on its own and its NSF certification could not be confirmed in NSF's public database, so it suits blenders and bakers better than athletes who need verified testing.

Best for

  • Smoothies, oats and baking
  • People avoiding sweeteners and additives
  • Minimalist ingredient lists

Skip it if

  • Anyone who wants a tasty shake with just water
  • Drug-tested athletes who need verifiable certification
  • People who are very lactose-sensitive

Our review

Naked Whey is the minimalist's protein powder. The unflavored version lists a single ingredient, whey protein concentrate, which the brand says comes from grass-fed cows on small dairy farms and is cold processed. There are no sweeteners, flavors, gums or lecithin. A 30 g serving (about two scoops) provides 25 g of protein and 5.9 g of naturally occurring BCAAs, with 120 calories, 3 g of carbohydrate and 2 g of sugar.

That small amount of sugar is naturally occurring lactose, so people who react strongly to dairy sugar may do better with an isolate; the brand sells a separate Naked Whey Isolate. For everyone else, 25 g of whey is a well-studied dose for supporting muscle protein synthesis after training.

Because it is unflavored, it shines in smoothies, oatmeal and baking, but most reviewers, including several fitness coaches on YouTube, say it tastes like plain milk powder on its own. buyers rate the 5 lb tub 4.3 stars across nearly 11,000 ratings, praising the clean ingredient list and quality while reporting clumping and foam when it is shaken rather than blended.

The label carries an NSF Contents Certified mark, but we could not find Naked Whey in NSF's public dietary supplement listings, which do list the company's creatine and pre-workout, so we treat that certification as unconfirmed. Batch certificates of analysis are not posted on the product page.

At $139.99 for 76 servings, about $1.84 per serving, it is fairly priced for a grass-fed whey.

Pros & cons

What we like

  • Single ingredient: grass-fed whey protein concentrate with no sweeteners or additives
  • 25 g of protein and 5.9 g of naturally occurring BCAAs per 30 g serving
  • Versatile in recipes because it has no flavor or sweetener
  • Large review base: 4.3 stars from nearly 11,000 buyer ratings

Watch-outs

  • Bland, milky taste on its own; most people blend it with other ingredients
  • Clumping and foaming are common complaints without a blender
  • The NSF Contents Certified claim could not be confirmed in NSF's public listings
  • Contains some lactose (2 g sugar per serving), unlike an isolate

Questions buyers ask

Does Naked Whey contain lactose?
Yes, a little. It is a whey concentrate rather than an isolate, and each serving lists 3 g of carbohydrate and 2 g of sugar, which in a single-ingredient whey product is naturally occurring milk sugar. Many people tolerate that amount, but those with significant lactose intolerance may prefer an isolate, including Naked's own whey isolate.
How do I make unflavored Naked Whey taste good?
Treat it as an ingredient rather than a finished shake. Blend it into smoothies with fruit, stir it into oatmeal or yogurt, or use it in pancakes and baking. The brand recommends blending for 20 to 30 seconds because there are no added ingredients to help it mix, which also cuts down on clumps.
Is Naked Whey third-party tested?
The label and product page say it is Contents Certified by NSF. When we checked NSF's public listings, Naked's creatine and pre-workout appeared but Naked Whey did not, so we could not confirm the claim. Competitive athletes should choose a product they can verify in the NSF or Informed Choice databases.
