Naked Nutrition
Quick verdict: Naked Nutrition took the obvious idea nobody else committed to: sell the protein and stop there. Naked Whey is one ingredient. No sweetener, no gum, no flavor. It’s Informed Choice tested, it’s founder-owned, and per serving it undercuts most of this category. You will taste the honesty. Our rating: 4.2 out of 5.
Who they are
Stephen Zieminski was a cross-country All-American working in New York finance when he started reading supplement labels properly. He founded Naked Nutrition in Miami in 2014 on a single premise, which the company still uses as its line: nutrition with nothing to hide.
The range has grown to well over a hundred products since, but the flagship hasn’t changed. Naked Whey is grass-fed whey concentrate and that’s the entire ingredient list.
What they get right
One ingredient means there’s nothing to argue about. Most “clean” protein still carries a sweetener, a gum, a flavor system and an anti-caking agent. Strip those out and the label stops being a negotiation. If you’ve ever tried to work out what “natural flavors” covers, this is the brand that makes the question unnecessary.
Informed Choice, which is the right certification for this product. Run by LGC, it tests batches for banned substances on a rolling monthly basis. The gluten-free claim is certified separately through GFCO rather than self-declared, and manufacturing runs under cGMP in an FDA-registered facility.
The price per serving is the quiet argument. The headline range looks wide because the tubs run from small to five pounds, but bought at size it works out cheaper per serving than nearly every brand in our clean protein roundup. Cheap and clean rarely appear together in this aisle.
Where they fall short
It tastes like plain whey, because it is plain whey. Unflavored and unsweetened is the whole point, and it also means you need to bring something to the glass. Fruit, milk, cocoa, something. Shaken with water it’s austere.
The certification stack is narrower than the label suggests. Informed Choice and GFCO are real and audited, but neither is organic and neither covers the company’s operations. There’s no B Corp, no USDA Organic on the whey, and the heavy-metal testing is the brand’s own third-party program rather than a certification you can look up. Reviews have found trace heavy metals present, which is true of most protein powders tested and worth knowing rather than being alarmed by.
The range has got big. A hundred-plus products is a long way from five, and some of the newer lines carry more ingredients than the originals. Read the specific tub, not the brand story.
What they sell and what it costs
Whey concentrate and isolate, casein, goat whey, pea and rice protein, collagen, creatine and a peanut butter powder. Tubs run from roughly $27 to $90 depending on size, and the large sizes are where the value is.
Who it’s actually for
Anyone who wants to know exactly what’s in the shake because there’s only one thing in it, and anyone buying protein weekly who can’t justify $50 a tub. If flavor matters more than the ingredient count, this isn’t your brand and we’d point you at Truvani instead.

Frequently asked questions
Is Naked Nutrition actually one ingredient?
Naked Whey is, yes: grass-fed whey concentrate, nothing else. So are Naked Pea and Naked Rice. The flavored versions add organic cocoa or vanilla and coconut sugar, so they run to three or four ingredients rather than one. The brand is clear about which is which on each product page.
Is Naked Nutrition third-party tested?
It carries Informed Choice Trusted by Sport, an LGC program that tests batches monthly for banned substances, and its gluten-free claim is certified through GFCO. The company also runs independent heavy-metal testing, though that’s its own program rather than a certification with a public register you can search.
Who owns Naked Nutrition?
Stephen Zieminski, who founded it in 2014 and still runs it from Miami. No acquisition or controlling outside investor appears on the record, which in a supplement category full of holding companies is worth saying out loud.
Does Naked Nutrition taste bad?
Unflavored whey tastes like unflavored whey, so “bad” isn’t quite it. Plain is closer. Most people blend it with fruit, milk or cocoa rather than drinking it with water. If you want something you’ll enjoy neat, buy a flavored clean protein and accept the longer label.
