Prozis Review: Supplements and Nutrition
Updated October 28, 2026
Our verdict on Prozis: 7.5/10
Prozis has established itself as an essential mass-market player, offering a massive catalog at highly competitive prices. This aggressive pricing is made possible by complete control over its production chain, entirely based in Portugal. The brand stands out through this in-house manufacturing and the selective use of high-quality patented ingredients, such as Creapure® creatine and Peptan® collagen.
My overall impression is of an extremely practical brand for its diversity and affordability. It’s the perfect “one-stop-shop” for an athlete’s daily needs. However, it raises legitimate questions about transparency regarding the origin of certain raw materials and about the sometimes lengthy ingredient lists loaded with additives in their most processed food products.
Prozis is a formidably efficient powerhouse. Its strengths are undeniable: a massive catalog where you can find absolutely everything, aggressive pricing, and integrated production that gives it remarkable agility. The use of patented ingredients like Creapure® or Peptan® on certain key products shows a selective commitment to quality. However, its weaknesses are equally clear: a lack of transparency about raw material origins, sometimes complex formulations in processed products, and customer service that seems to be their Achilles' heel. Prozis is a very smart choice for budget-conscious athletes and beginners looking to gear up without breaking the bank.

Who is Prozis for?
Recommended
- I recommend Prozis to beginner athletes or those on a tight budget looking for the best value for money. It's an excellent choice if you like to mix things up and try a wide range of different flavors. Also ideal for those looking for a convenient "one-stop-shop" to order supplements, healthy snacks, and even workout clothes in a single order.
Not recommended
- I don't recommend Prozis if you demand complete transparency on the origin of every ingredient. The brand is also not suitable if you prioritize "clean" formulations with minimal additives, or if responsive and reliable customer service is a non-negotiable criterion for you.

About Prozis
Prozis is a Portuguese sports nutrition brand founded in 2007, often referred to as the "fitness supermarket." The company has established itself as an essential mass-market player thanks to its massive catalog, aggressive pricing, and complete control over its entire production chain.
In this article, I've done a deep dive into this industry giant: its philosophy, product quality, formulations, and customer feedback. Here's my review of Prozis after comparing their products to other players like in my MyProtein review or my Bulk review.
Founded in 2007 in Portugal, Prozis's story began as an online platform distributing products from established brands. However, the company quickly made a major strategic pivot by investing in its own production facilities. Today, Prozis has evolved to sell almost exclusively its own products, designed and manufactured in its own factories.

Prozis's Values & Positioning
Prozis has positioned itself as the "fitness supermarket," with a mission to democratize sports nutrition. Its business model relies on a 100% digital approach and aggressive pricing, made possible by total control over the value chain. From formulation to labeling to manufacturing, everything is managed in-house at their ISO-certified Portuguese facilities.
Unlike premium American brands like those analyzed in some of my reviews, Prozis prioritizes volume and price accessibility over purity of formulations. This approach allows them to offer a very broad selection at prices that beat the competition.
Who Is Prozis's Founder
The brand was created by Portuguese entrepreneur Miguel Milhão. His journey is that of a self-made man who built an empire from a garage, transforming a simple distribution platform into a European sports nutrition giant.
However, his public statements and direct communication style are sometimes perceived as controversial. His strong opinions regularly fuel debates and even push some consumers away from the brand, as evidenced by certain reviews.
Prozis's Product Lineup
The Prozis catalog is one of the most extensive on the market, covering far more than just sports nutrition. This diversity is what earned it the nickname "fitness supermarket."
On the protein side, 100% Real Whey Protein is their accessible best-seller, ideal for beginners thanks to its excellent value. Pure Native Isolate offers an option for purists, with its cold extraction process better preserving protein integrity. Whey Hydro Isolate is designed for ultra-fast post-workout absorption. Plant-based options like 100% Vegan Protein meet the needs of a growing customer base.
For performance, Creapure® Creatine is a benchmark for purity, manufactured in Germany. BigShot Pre-Workout is a complete booster combining stimulants and nitric oxide precursors. BCAAs are available in numerous ratios and flavors.
The health and wellness range includes Multi PRZ (multivitamins), concentrated Omega-3s, and Marine Collagen formulated with the patented ingredient Peptan®.
What truly sets Prozis apart is its healthy food range: 100% natural Peanut Butter, Oatmeal available in dozens of flavors, Whey Choco Butter (protein spread), very low-calorie Konjac Noodles, sugar-free and fat-free Zero Sauces, and the indulgent Billion Bars protein bars.
What Users Say About Prozis
With an overall rating of 4.2/5 on Trustpilot, based on over 173,000 reviews, Prozis shows mostly positive customer satisfaction. This volume of reviews reflects the brand's massive customer base.
Positive reviews almost unanimously highlight ultra-fast shipping, highly competitive prices that beat all competition, and the huge selection that lets you find everything in one place. The loyalty program is also well-received.
On the flip side, the most recurring pain points involve customer service described as "terrible" or unresponsive by some users, packages arriving damaged (the "torn bag of oatmeal" is a classic complaint), and for some processed products, a chemical taste or disappointing texture.
Customer Reviews of Prozis
"Maybe it's the flavor I chose (cinnamon roll) but I didn't like it. That said, the Prozis brand is great and has other products that are really top-notch."
sportif-nono - Diet Bar Review
"A bag of oatmeal with a hole in the bottom of the package with flour spilled all over the box."
Testimonial reported by STEPUP GYM
"Customer service is terrible, going so far as to basically call customers 'liars' when filing complaints."
