What is the IronMaxx ZENITH® 50 Protein Bar?
The IronMaxx ZENITH® 50 is the brand's flagship protein bar — a 100g bar delivering 50g of protein at 50% protein by weight, with a maximum of 2.1g of sugar across the three stocked flavours. It stands apart from the standard 50 to 60g protein bar market by its full 100g format, making it one of the highest-protein ready-to-eat bars available in the European sports nutrition market.
The protein matrix combines milk protein blend (whey and caseinate fractions from milk protein and milk protein concentrate) as the primary source with collagen hydrolysate (bovine) and soy protein crispies — three complementary protein sources providing different absorption timelines and the bar's characteristic dense yet soft texture. The sweetener system uses maltitol (in the chocolate coating) and steviol glycosides, keeping sugar content to a maximum of 2.1g per 100g bar.
Three flavours are stocked. Milk Chocolate Crisp features a dark maltitol chocolate couverture (16.5%) with 4% soy crispies and 1.5% fat-reduced cocoa powder for a rich, brownie-style chocolate experience. White Chocolate Crisp uses a white maltitol chocolate couverture (17%) with 5.5% soy crispies and almond flour for a creamy white chocolate character with crunch — the only variant containing tree nuts. Stracciatella Crisp is the most distinctive — a dark maltitol chocolate couverture (16.5%) with 4% soy crispies and 1.8% real cocoa nibs creating a Stracciatella gelato-inspired experience: crunchy chocolate pieces throughout a chocolate-coated protein bar at just 1.1g of sugar.
Gluten-free across all three variants. Produced in Germany. IronMaxx holds the German State Honour Award for Excellent Food Quality from North Rhine-Westphalia.
50g of protein. 100g of bar. Three genuinely different chocolate experiences.

💪 50g of protein per 100g bar — the largest and highest-protein bar in the range
At 100g per bar and 50% protein content, the ZENITH® 50 provides 50g of protein — equivalent to approximately 200g of chicken breast, 8 eggs or nearly two standard protein shakes. For athletes who need to hit high daily protein targets conveniently, a single ZENITH® 50 bar covers the protein contribution of a full meal without requiring preparation, cooking or refrigeration.
🧬 Multi-source protein — milk, collagen and soy for complementary coverage
The protein matrix delivers amino acids across multiple timelines: milk protein blend (whey and caseinate fractions) provides both fast and sustained amino acid release; collagen hydrolysate contributes glycine, proline and hydroxyproline for connective tissue support; soy protein crispies add a complete plant-based EAA complement alongside the bar's characteristic crunchy texture elements.
🚫 Maximum 2.1g of sugar — genuine low-sugar at 100g serving
Standard chocolate bars of 100g contain 40 to 60g of sugar. The ZENITH® 50 contains a maximum of 2.1g of total sugars per 100g bar — a reduction of over 96%. The maltitol-based chocolate coatings and steviol glycosides produce a genuinely sweet and indulgent taste without added sugar.
🍦 Stracciatella Crisp — cocoa nibs for an authentic gelato-inspired experience
The Stracciatella variant uses 1.8% real cocoa nibs alongside 4% soy crispies — inspired by stracciatella gelato: a creamy base studded with irregular chocolate pieces. The combination of the dark chocolate coating, the crunchy soy crispies and the cocoa nib inclusions creates the most texturally complex of the three stocked flavours, at just 1.1g of sugar per 100g bar.
🤍 White Chocolate Crisp — almond flour for added nuttiness and indulgence
The White Chocolate Crisp variant is the only one of the three to contain almond flour — a tree nut ingredient that adds a subtle nutty depth to the white chocolate base alongside 5.5% soy crispies for a premium, complex flavour profile.
🌾 Gluten-free — broad dietary accessibility
All three stocked ZENITH® 50 variants are declared gluten-free. The formula uses no wheat, rye, barley or oat-derived ingredients.
🎯 Goal guide
🏋️ Mass gain: 1 bar/day as a post-workout protein source or between-meal protein top-up. 50g of protein per bar significantly reduces the additional protein sources needed to hit daily targets.
🔥 Weight loss / cutting: 1 bar/day. Maximum protein at minimum sugar — the ideal caloric-deficit protein snack at 100g.
⚖️ Body recomposition: 1 bar/day post-workout. Multi-source protein for sustained amino acid delivery throughout the recovery window.
Serving suggestion
Open the wrapper and consume directly. No preparation required. IronMaxx recommends consuming 1 to 2 bars per day at any time of day — before, during or after training or as a protein-rich snack. Store protected from heat, moisture and direct sunlight. The chocolate coating may soften in warm conditions — this is cosmetic only and does not affect nutritional content.
Best times to enjoy it
🏋️ Post-workout
50g of protein within 30 to 45 minutes of training provides a complete multi-source protein dose during the peak anabolic window — covering the protein contribution of an entire meal in a single convenient bar that requires no preparation.
☀️ As a meal replacement or between meals
At 100g and 50g of protein, the ZENITH® 50 is large enough to serve as a complete meal substitute for a protein-focused lunch or snack. The combination of protein, fat and crunchy soy crispies creates genuine satiety between meals during caloric restriction.
🌙 Evening high-protein snack
The caseinate fraction in the milk protein blend provides slow-releasing amino acids, making an evening ZENITH® 50 a practical anti-catabolic snack before sleep — comparable in function to a dedicated casein shake in a more enjoyable ready-to-eat format.
✈️ On the go
Individually wrapped and shelf-stable at room temperature — fits in any gym bag, backpack or briefcase. The 100g format provides a genuinely filling high-protein portable meal for travel or demanding working days.

Q1 — What is Stracciatella Crisp and how does it differ from the other two flavours?
Stracciatella is an Italian gelato flavour defined by a creamy base studded with irregular shards of dark chocolate — the name comes from the Italian verb "to shred." The IronMaxx ZENITH® 50 Stracciatella Crisp replicates this concept in bar form: a dark chocolate couverture coating with 4% soy crispies for crunch and 1.8% real cocoa nibs distributed throughout the bar matrix as the signature chocolate piece inclusions. At 1.1g of sugar per 100g, it also has the lowest sugar content of the three stocked flavours — significantly less than both the Milk Chocolate Crisp (2.1g) and White Chocolate Crisp (2.1g) variants.
Q2 — Why does White Chocolate Crisp contain almond flour when the other two do not?
Almond flour is an ingredient specific to the White Chocolate Crisp formula — it adds a subtle nutty undertone that complements the white chocolate flavour profile and contributes to the bar's texture alongside the 5.5% soy crispies. Milk Chocolate Crisp and Stracciatella Crisp do not contain almond flour. This makes White Chocolate Crisp the only variant with a declared tree nut allergen (almonds) — individuals with tree nut allergies must specifically avoid this variant.
Q3 — Is the ZENITH® 50 suitable for vegetarians?
No. All three stocked variants contain collagen hydrolysate from bovine (cattle) collagen — an animal structural protein used both as a secondary protein source and as a texture agent. Collagen cannot be sourced from plant or vegetarian ingredients. This applies equally to all three flavours.
Q4 — How does a 100g bar with 50g of protein compare to a standard protein bar?
Most standard protein bars weigh 50 to 65g and provide 20 to 25g of protein. The ZENITH® 50 at 100g and 50g of protein provides double the protein per bar and double the serving size — equivalent to two standard protein bars in one. For athletes who need protein-equivalent meal replacements rather than snack-sized supplements, this larger format provides exceptional value per gram of protein and a genuinely filling eating experience.
Q5 — Is the box of 12 the same product as the individual bar?
Yes. The box of 12 contains 12 individually wrapped 100g bars of the same formula as the individually sold bar. The box format provides a meaningfully lower cost per bar and is the preferred format for athletes who consume ZENITH® 50 regularly. At one bar per day, the box provides 12 days of supply.
