I started buying protein powder during a winter training block when my old tub ran out and I needed something the next morning. Rather than drive to a supplement shop, I ordered from a website I’d used once for a shaker bottle. Two days later a 2 lb tub of whey showed up and it cost less than half what I’d paid in store. That gap is the whole reason Prozis has become my default for the boring stuff.
For anyone who hasn’t come across them: Prozis is a Portuguese sports nutrition company founded in 2007 by Miguel Milhão. It started as an online distributor for other brands, then bought its own factories and now manufactures almost everything it sells in ISO-certified plants in Portugal. The company calls itself the “fitness supermarket,” and that’s not marketing fluff — the catalog runs from whey powder and creatine to low-calorie sauces, oatmeal, protein spreads, leggings and home gym kit, all shipped from one warehouse.
Why the Prices Are This Low

Because there are no middlemen. Prozis designs a formula, makes it in its own facility, labels it, and ships it directly to your door. That vertical setup is why a 2 lb tub of 100% Real Whey Protein sits around €50 in Europe and shows up at US promotional prices in the high $30s, while a tub of the same category from a premium brand regularly runs double that. Clear Whey Isolate in the watermelon flavour has been as low as $22 for 1.1 lb during campaigns.
Work out the per-serving cost and it gets clearer. At the promo price, a 30 g serving of their standard whey lands around $1.28, Clear Whey works out near $1.10, and a 5 g serving of their Creapure® creatine monohydrate comes to roughly $0.34 a day. Those numbers are why Prozis keeps showing up on “cheapest protein” lists — the discount is real and it’s not a trial-size teaser.
What I’d Actually Buy From Them
The beginner pick is 100% Real Whey Protein. It mixes clean in water, the flavour range is broad, and it’s forgiving enough that a slightly off ratio doesn’t taste like punishment. If you’re purist, Pure Native Isolate uses cold extraction and preserves the protein better, though it costs more per scoop. Whey Hydro Isolate is the fast-absorption option I use after leg days, and there’s a 100% Vegan Protein if plant-based is your thing.
On the performance side, Creapure® Creatine is the one I trust most, because Creapure is a branded German ingredient with documented batch controls, not “some creatine.” BigShot Pre-Workout combines stimulants with nitric oxide precursors, and the Multi PRZ multivitamin plus Marine Collagen with Peptan® cover the wellness side. They also sell BCAAs in several ratios if that’s your habit.
The food range surprised me more than the supplements. Zero Sauces are genuinely low calorie and useful during a cut, Billion Bars are protein bars that taste like a treat, and there’s conjac noodles, peanut butter and instant oatmeal in dozens of flavours. One cart, one shipping fee — that’s where the one-stop-shop thing actually pays off.
The Downsides Nobody Puts on the Box

Customer service is the one people complain about most, and the reviews do get ugly — there are accounts of support staff dismissing complaints as nonsense. Packaging is the second complaint, and it’s specific: there are multiple reports of oatmeal bags arriving with holes in the bottom and powder spilling through the box. It’s not every order, but if you’re buying in bulk, check the bag before you open it.
There are also honest questions about transparency. Prozis doesn’t publish independent lab test results for the range, and some of the more processed food products draw complaints about chemical aftertaste and texture. The brand does market a Doping-Free category, but that covers specific products and batches — verify the exact item and lot rather than assuming the whole catalog is tested. And founder Miguel Milhão is outspoken in a way that some customers love and others find off-putting.
Who Should Buy From Prozis
If you’re starting out, training on a budget, or you want protein, creatine, sauces and gymwear without paying four separate shipping fees, it’s a genuinely good deal. Free shipping kicks in at $29.99 in the US, returns are accepted for 30 days, and Trustpilot ratings sit around 4.2 out of 5 across more than 170,000 reviews. Independent reviewers tend to land between 7.5 and 8.7 out of 10, which is about right for a brand this price-driven.
What I’d skip: buying eight flavours at once, and ordering anything fragile in a single large shipment. Start with one tub, see how it mixes for you, and only then go big. If ingredient lists need to fit on one line and every product needs third-party testing published, you’re paying for a different kind of brand — and quite a bit more money.
Protein, creatine, low-calorie sauces and gymwear — free US shipping over $29.99.
