AM Nutrition vs. Prozis: A Comprehensive Comparison of Two Leading Sports Nutrition Brands
For athletes and fitness enthusiasts in Europe, the choice between AM Nutrition and Prozis often hinges on priorities like ingredient quality, pricing, and product variety. AM Nutrition, a French brand founded in 2004, emphasizes traceable French milk and clean formulations, while Prozis, a Portuguese superstore established in 2007, offers a vast range of fitness products at competitive prices. Both brands have distinct strengths, but their differences reflect contrasting approaches to sports nutrition.
Quality of Whey Proteins: Traceability vs. Volume
AM Nutrition’s PURE Whey Isolate uses Eurinutri 90® from French dairy cooperative EURIAL, delivering 91% protein content with integrated lactase for easier digestion. This isolate is marketed as “100% clean,” with no artificial colors or flavors, and publishes detailed analysis certificates for each product. According to AM Nutrition’s website, the whey is sourced from French milk, emphasizing transparency.

In contrast, Prozis’s 100% Real Whey Protein is a standard concentrate with approximately 75% protein. While Prozis does not specify the milk’s origin, its Native Whey Isolate offers a premium alternative closer to AM Nutrition’s profile.
Pricing and Value: Budget-Friendly vs. Premium Formulations
Prozis dominates in price competitiveness, with its Real Whey Protein averaging ~25 €/kg, often discounted. AM Nutrition’s PURE Whey Concentrate costs ~33 €/kg, but offers higher protein content (concentrée AM ~80% vs. concentrée Prozis ~75%). This gap reflects AM Nutrition’s focus on purity and French sourcing, while Prozis emphasizes accessibility.
Prozis also provides added value through its ProzisPoints loyalty program, allowing customers to redeem points for free products. AM Nutrition, however, does not offer similar incentives, focusing instead on product quality and athlete endorsements like MMA fighter Amin Ayoub and weightlifter Vicky Graillot.
Product Range: Specialized Clean Nutrition vs. All-in-One Fitness Store
AM Nutrition’s catalog centers on sports nutrition and health supplements, including collagen, ashwagandha, and creatine. It excludes lifestyle products like snacks or clothing, catering to athletes prioritizing clean, functional ingredients. Prozis, by contrast, boasts over 5,000 references, including zero-sugar sauces, protein bars, and konjac noodles, alongside fitness apparel and skincare.
This breadth makes Prozis a one-stop shop for fitness enthusiasts, though its formulations sometimes include artificial sweeteners like sucralose. AM Nutrition’s commitment to “clean” labels—no artificial flavors or colors—resonates with health-conscious consumers, despite its narrower selection.
Customer Experience: Reliability vs. Scalability
AM Nutrition earns a 4.75/5 rating on Judge.me (5,384 reviews) for product quality but scores 4.3/5 on Trustpilot (373 reviews) due to mixed shipping experiences. Some customers report delayed deliveries, though product satisfaction remains high. Prozis, with thousands of Trustpilot reviews, scores 4.7/5, praised for fast shipping and free samples, though its phone support and damaged package handling have drawn criticism.

Key Takeaways: Choosing Based on Priorities
- AM Nutrition: Best for athletes seeking French-sourced, high-purity whey with lactase for digestion. Ideal for those prioritizing clean labels and traceability.
- Prozis: Optimal for budget-conscious shoppers needing a wide range of fitness products, including snacks and supplements, with robust loyalty rewards.
Both brands meet foundational sports nutrition needs, but the decision depends on whether consumers value ingredient transparency and purity (AM Nutrition) or cost-effectiveness and variety (Prozis).
