Grenade High Protein Bar

How the Grenade Carb Killa Protein Bar supports your objectives

💪 20g of multi-source protein — caseinate, whey isolate and collagen

Each 60g bar provides 20g of protein from three complementary sources. Calcium caseinate is the slow-digesting casein fraction, extending amino acid availability for 4 to 6 hours — ideal for anti-catabolic protection between meals and overnight. Whey protein isolate is the fastest-absorbing dairy protein, providing an immediate amino acid spike for post-workout synthesis. Hydrolysed bovine collagen contributes structural protein peptides for skin elasticity, joint comfort and connective tissue integrity. The three sources together create a multi-phase delivery profile superior to any single-source protein bar.

🚫 Less than 2g of sugar — genuine low-sugar indulgence

Standard chocolate confectionery bars contain 20 to 30g of sugar per 60g serving. The Carb Killa contains less than 2g — a reduction of over 90%. The sweetness is delivered by maltitol (a sugar alcohol with lower glycaemic impact than sucrose) and sucralose, making the bars suitable for low-sugar, controlled-carbohydrate and body recomposition dietary approaches.

🍫 Tastes like a real chocolate bar — the defining differentiator

The Carb Killa's sustained market leadership is built on one foundation: it tastes genuinely good. The milk chocolate coating (25% of the formula, made with whole milk powder and cocoa butter), the soft, yielding filling texture and the real flavour inclusions (Oreo pieces, cookie dough, peanut pieces, raspberry layers) create an eating experience that is indistinguishable from premium confectionery for most consumers. This is why the Carb Killa converts casual browsers into repeat buyers at a rate that no competitor has matched.

🏆 Informed Sport certified — sports banned substance tested

The Carb Killa carries Informed Sport certification — a third-party testing programme that screens every production batch for over 250 substances on the WADA prohibited list. This certification makes the Carb Killa suitable for competitive athletes at all levels, including those competing in tested sports, without risk of inadvertent anti-doping violations.

🌟 Oreo and Oreo White — licensed collaborations

Two of the eight stocked flavours are official licensed Oreo collaborations: Oreo and Oreo White. These bars contain real Oreo cookie pieces incorporated into the formula — not Oreo flavouring or "cookie-style" pieces. The use of the genuine Oreo licence and real Oreo inclusions is a meaningful quality differentiator and a significant driver of Carb Killa's social media and retail visibility.

🎯 Goal guide

🏋️ Mass gain: 1 to 2 bars/day post-workout and between meals. 20g of multi-source protein with minimal sugar.

🔥 Weight loss / cutting: 1 bar/day. High-protein, low-sugar snack replacing conventional confectionery during caloric restriction.

⚖️ Body recomposition: 1 bar/day. Clean protein delivery with the eating experience of a chocolate bar.

Serving suggestion

Open the wrapper and consume directly. No preparation required. Consume 1 bar 1.5 to 2 hours before training to avoid digestive discomfort, or immediately after training as a post-workout protein source. Can also be consumed at any time of day as a high-protein snack. Store in a cool, dry place away from direct sunlight.

Best times to enjoy it

🏋️ 1.5 to 2 hours before training

Consuming a Carb Killa bar 1.5 to 2 hours before training provides a sustained protein supply during the session from the casein fraction, while the maltitol carbohydrates provide a moderate, sustained energy contribution without the blood glucose spike of conventional pre-workout snacks.

⚡ Immediately post-workout

The whey isolate fraction delivers fast amino acids into the bloodstream within 30 to 60 minutes, initiating the post-workout protein synthesis window alongside the slower caseinate fraction that sustains delivery for the following 4 to 6 hours.

☀️ Mid-morning or mid-afternoon snack

Replacing a conventional chocolate bar or snack with a Carb Killa delivers 20g of protein at under 242 kcal, transforming an empty caloric snack moment into a meaningful daily protein contribution.

🌙 Evening dessert substitute

The Oreo, Oreo White, Chocolate Chip Cookie Dough and White Chocolate Cookie variants are particularly effective as evening dessert substitutes, providing the indulgent eating experience of confectionery at less than 2g of sugar and 20g of protein.

✈️ On the go

Each bar is individually wrapped, shelf-stable at room temperature and requires no preparation — the most portable high-protein snack available.

Daily protein target reminder

Current sports nutrition science recommends 1.6 to 2.2g of protein per kg of body weight per day for active individuals. Each Carb Killa bar contributes 20g toward this daily target.

Box format guide

Q1 — Why is the Grenade Carb Killa the UK's #1 protein bar?

The Carb Killa achieved and has sustained UK market leadership since 2018 for one primary reason: it was the first protein bar to genuinely solve the taste-protein trade-off. Every protein bar before it asked consumers to accept a worse eating experience in exchange for nutritional benefit. The Carb Killa's milk chocolate coating, soft filling, real flavour inclusions and licensed Oreo collaborations deliver a confectionery-quality eating experience at 20g of protein and less than 2g of sugar — a combination that no competitor had achieved at scale before its launch. Consumer repeat purchase rates in the protein bar category are unusually high for Carb Killa precisely because the bar actually delivers on its promise every time.

Q2 — What is the difference between the protein sources in Carb Killa (caseinate, whey isolate, collagen)?

The three protein sources address distinct nutritional functions. Calcium caseinate is a slow-digesting dairy protein that releases amino acids steadily for 4 to 6 hours — providing anti-catabolic protection between meals and during sleep. Whey protein isolate is the fastest-absorbing complete protein available, with peak plasma amino acids within 60 minutes of consumption — ideal for the post-workout anabolic window. Hydrolysed bovine collagen provides glycine, proline and hydroxyproline — the specific amino acids used in connective tissue, skin and cartilage synthesis, which are not present in sufficient quantities in whey or casein. Together, the three sources cover fast recovery, sustained anti-catabolism and structural tissue support simultaneously.

Q3 — Are the Oreo and Oreo White variants genuinely made with real Oreo pieces?

Yes. Both the Oreo and Oreo White Carb Killa bars are produced under an official Oreo brand licence and contain real Oreo cookie pieces incorporated into the bar formula. The "Oreo" branding on these variants is not a flavour description — it reflects the genuine use of Oreo cookies as an ingredient. This makes them unique within the protein bar category and a primary driver of Grenade's social media visibility.

Q4 — Is the Carb Killa suitable for competitive athletes?

Yes. The Carb Killa carries Informed Sport certification — a globally recognised third-party testing programme that screens every production batch against the WADA prohibited substances list. Athletes competing in tested sports (including WADA-governed sports, anti-doping tested competitions and professional leagues with substance testing) can consume the Carb Killa without risk of inadvertent anti-doping violations.

Q5 — Is the box of 12 more economical than individual bars?

Yes. The box of 12 provides a meaningfully lower cost per bar than purchasing individually and is the standard format for athletes and regular consumers. At one bar per day, the box provides 12 days of supply. For variety, different flavours can be mixed in orders — always verify availability at time of purchase for each stocked flavour.
