BioTechUSA Zero Bar

How the Zero Bar Protein by BiotechUSA supports your objectives

🧬 20g of protein from a five-source protein blend The combination of whey protein isolate, egg white protein, hydrolysed protein, calcium caseinate and soy protein isolate creates a multi-phase protein delivery profile covering rapid, intermediate and sustained amino acid release. The hydrolysed fraction provides the fastest possible amino acid availability post-workout; the caseinate fraction extends delivery over 4 to 6 hours. This staggered release supports both the immediate post-exercise anabolic window and the anti-catabolic period between meals.

🚫 No added sugar — naturally sweetened with sucralose and maltitols Zero Bar contains no added sugar. The sweetness comes from maltitols (sugar alcohols naturally present in the protein matrix) and sucralose. Total sugars per bar are approximately 0.45g to 0.95g — all naturally present, none added. This makes Zero Bar genuinely compatible with low-sugar and ketogenic dietary approaches, and suitable for individuals managing blood glucose levels.

🌿 FOS (fructooligosaccharides) — prebiotic fibre for gut health Each bar contains fructooligosaccharides, short-chain soluble fibres that resist digestion and reach the colon intact, where they selectively feed Bifidobacterium and other beneficial gut bacteria. Regular FOS consumption contributes to gut microbiome diversity and digestive comfort — a dimension of nutritional quality that most protein bars do not address.

🧡 Vitamin E — antioxidant protection Each bar provides vitamin E (DL-alpha-tocopheryl acetate), which carries the EU-authorised health claim for contributing to the protection of cells against oxidative stress. For athletes whose training generates elevated free radical production, the regular inclusion of a vitamin E source in a daily snack provides cumulative antioxidant support.

🍽️ Lactose-free and gluten-free — the broadest possible dietary compatibility Zero Bar is lactose-free (the caseinate and whey isolate fractions are processed to remove lactose) and gluten-free (no gluten-containing ingredients). It is suitable for individuals with lactose sensitivity, coeliac disease or gluten intolerance — making it one of the most broadly accessible protein bars available in its category.

🎯 Goal guide

🏋️ Mass gain: 1 to 2 bars/day post-workout or between meals. Five-source protein blend for sustained amino acid supply during a caloric surplus.

🔥 Weight loss / cutting: 1 bar/day. No added sugar, high protein, high fibre — the ideal diet-phase protein snack.

⚖️ Body recomposition: 1 bar/day post-workout. Clean protein, low sugar, prebiotic fibre for comprehensive daily nutrition support.

Serving suggestion

Open the wrapper and consume directly. No preparation required. Consume after training or at any time of the day. Store in a cool, dry place below 25°C, away from direct heat and sunlight. Not recommended for children or pregnant women due to the caffeine content in the Cappuccino variant.

Best times to enjoy it

🏋️ Post-workout The five-source protein blend — including the hydrolysed fraction for immediate amino acid delivery and the caseinate for sustained release — makes Zero Bar an effective post-workout protein source. The combination of fast and slow proteins addresses both the immediate and extended post-exercise protein synthesis window simultaneously.

☀️ Between meals as a high-protein snack The prebiotic FOS fibre and multi-source protein matrix make Zero Bar particularly effective as a between-meal satiety snack. The slow-releasing caseinate fraction extends fullness for 2 to 3 hours after consumption, reducing inter-meal cravings.

🌙 Evening (except Cappuccino variant) All variants except Cappuccino are caffeine-free, making them suitable for evening consumption. An evening bar provides a casein-driven slow-release protein top-up that partially replaces the need for a dedicated pre-sleep protein shake.

✈️ On the go — zero preparation, zero mess Each bar is individually wrapped, shelf-stable at room temperature below 25°C and requires no preparation, shaker or water. The uncoated format eliminates the risk of melted chocolate coating in warm conditions — a practical advantage over coated protein bars.

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 Zero Bar contributes 20g of protein toward this daily target.

*Total daily protein should come from a combination of Zero Bars and whole food sources.

Goal-specific guidance

For weight loss and cutting: Zero Bar is particularly effective during caloric restriction because of its combination of high protein (satiety from amino acids), FOS fibre (satiety from prebiotic fibre's delayed gastric emptying effect) and no added sugar (no glucose-driven insulin spike and crash). At approximately 177 kcal per bar with 20g of protein, the protein-to-calorie ratio is excellent for a solid-food snack format.

For mass gain: Use 1 to 2 bars per day as high-quality between-meal protein top-ups within a caloric surplus diet. The five-source protein blend provides a more complete and sustained amino acid supply than a whey-only bar, supporting continuous muscle protein synthesis between whole-food protein meals.

🏅 Sport Nutrition "Did you know?"

The five-protein blend of Zero Bar includes calcium caseinate — a form of casein derived from milk that is distinct from micellar casein. Unlike micellar casein (which forms a gel in the stomach), calcium caseinate disperses more freely in the digestive system but still releases amino acids more slowly than whey, providing a 2 to 4 hour sustained amino acid supply. Its inclusion alongside the fast-absorbing hydrolysed protein fraction and the medium-speed egg white and whey isolate creates a protein release profile that spans the full spectrum from immediate to sustained — a degree of nutritional sophistication rarely seen in a compact 50g bar format.

Box format guide

Q1 — What makes the Zero Bar protein blend different from a standard whey protein bar? Most standard protein bars use one or two protein sources — typically whey concentrate or a concentrate/isolate blend. Zero Bar uses five distinct proteins: whey isolate (fast), egg white (medium-fast), hydrolysed protein (fastest), calcium caseinate (slow) and soy isolate (medium). This creates a multi-phase protein release profile covering the full spectrum from immediate to sustained amino acid delivery. The result is a bar that supports both the immediate post-workout anabolic window and the anti-catabolic inter-meal period simultaneously — a degree of protein sophistication not achievable with a single-source formula.

Q2 — Is Zero Bar suitable for people with lactose intolerance? Yes. Zero Bar is declared lactose-free. The whey protein isolate fraction is processed to remove lactose to below 0.1g per 100ml of equivalent liquid, and the calcium caseinate similarly contains minimal lactose. BiotechUSA has confirmed lactose-free status across the Zero Bar range. This makes it one of the few multi-protein bars that is suitable for individuals with lactose sensitivity who want the benefits of both whey and casein proteins without digestive consequences.

Q3 — Does Zero Bar contain caffeine? Only the Cappuccino variant contains caffeine — 18mg per 100g, which is approximately 9mg per 50g bar, from the 0.4% instant coffee ingredient. This is a very modest caffeine content (approximately one tenth of a standard espresso), but it is declared on the label and the variant is not recommended for children or pregnant women. All other seven variants (Chocolate Hazelnut, Chocolate-Caramel, Chocolate-Coconut, Banana-Chocolate, Double Chocolate, Chocolate Chip Cookie and Chocolate-Marzipan) are caffeine-free.

Q4 — What are the FOS (fructooligosaccharides) in Zero Bar? FOS are short-chain soluble prebiotic fibres that resist digestion and reach the large intestine intact, where they selectively feed Bifidobacterium and Lactobacillus species — the beneficial bacteria associated with improved gut health and immune function. Their inclusion in Zero Bar adds a functional dimension beyond simple protein delivery: consistent daily intake of FOS contributes to gut microbiome diversity and digestive regularity. This is particularly relevant for athletes on high-protein diets, where adequate fibre intake can be challenging.

Q5 — Is the box of 20 the same product as the individual bar? Yes. The box of 20 contains 20 individually wrapped 50g bars of the same formula as the individually sold bar. The box format is the most economical choice per bar and is the standard purchasing format for athletes who consume Zero Bars regularly. At one bar per day, the box of 20 provides three weeks of supply.
