Addict Isobolic

How Isobolic by Addict Sport Nutrition supports your objectives

🔬 100% whey isolate: the highest-purity protein source available Whey isolate undergoes a more intensive filtration process than whey concentrate, removing virtually all lactose and fat while concentrating protein content to 85% per serving. This level of purity means you are getting more protein per gram of powder, with fewer unwanted calories and no digestive interference from lactose — making Isobolic a premium choice for athletes who prioritise nutritional precision.

💪 25.5g of protein per serving with a complete amino acid profile Each 30g serving of Isobolic delivers 25.5g of high-quality protein with a complete essential amino acid (EAA) profile including all nine EAAs the body cannot synthesise. This complete profile supports all phases of muscle protein synthesis: the initiation, elongation and completion of new muscle protein strands that drive muscle growth and repair after training.

⚡ Naturally rich in BCAAs for muscle protein synthesis Whey isolate is among the richest natural sources of branched-chain amino acids (BCAAs), particularly leucine. Leucine is the primary activator of mTOR, the central signalling pathway that initiates muscle protein synthesis. The naturally high leucine content of Isobolic makes each serving a potent anabolic stimulus that works even without additional BCAA supplementation.

🏃 Fast absorption for post-workout recovery Whey isolate is a rapidly digesting protein with an absorption rate that peaks within 60 to 90 minutes of consumption. This rapid availability of amino acids in the bloodstream makes it ideal for the post-workout window, when muscle protein synthesis is most elevated and the demand for amino acids is at its highest. Isobolic delivers these amino acids exactly when muscles need them most.

🍃 Virtually lactose-free with added lactase enzyme The combination of the isolate filtration process (which removes the vast majority of lactose) with the addition of lactase enzyme (which breaks down any residual lactose) makes Isobolic exceptionally well-tolerated by athletes with lactose sensitivity. This is a practical and clinically relevant feature that many competing isolate products do not include.

🎯 Goal guide

🏋️ Mass gain: 2 to 3 servings/day. Post-workout and between meals to hit daily protein targets.

🔥 Weight loss / cutting: 1 to 2 servings/day. Low calorie, high protein — ideal to preserve muscle in deficit.

⚖️ Body recomposition: 1 to 2 servings/day post-workout. Maximum protein, minimum unwanted calories.

Serving suggestion

Mix 1 level scoop (30g) with 200 to 250ml of cold water. Shake vigorously in a shaker bottle until the powder is fully dissolved. For a creamier texture, use cold milk or a plant-based milk alternative instead of water. The amount of liquid can be adjusted to personal taste — more liquid for a lighter shake, less for a denser, more concentrated texture.

Best times to enjoy it

🏋️ Post-workout (primary window) Consume within 30 to 45 minutes after training to maximise muscle protein synthesis during the peak anabolic window following exercise.

🌅 Morning A fast-absorbing protein source taken at breakfast helps break the overnight fast and provides amino acids for muscle protection after hours without protein intake.

☀️ Between meals as a snack Replacing a low-protein snack with an Isobolic shake supports consistent protein distribution across the day, which research shows is more effective for muscle growth than front-loading protein in one or two large meals.

🌙 Before sleep (optional) While casein is traditionally recommended before sleep for its slower release, a serving of Isobolic before bed still contributes meaningfully to overnight muscle protein synthesis and is a practical option when casein is not 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. For vegan athletes, targeting the upper end (1.8 to 2.2g/kg) is advised. Each serving of Isobolic contributes 25.5g toward this daily target.

*Including protein from food sources. Isobolic servings are supplements to a protein-rich diet, not replacements for it.

Goal-specific guidance

For mass gain: Use 2 to 3 servings of Isobolic per day alongside a protein-rich, calorie-surplus diet. Combine with complex carbohydrates at post-workout to maximise the insulin-stimulated amino acid uptake into muscle tissue. Isobolic's low fat and sugar content leaves room in your daily calorie budget for the carbohydrates and additional calories needed to support lean muscle growth.

For weight loss and cutting: Isobolic is particularly well-suited to cutting phases due to its very high protein density relative to its caloric content. A single 30g serving provides 25.5g of protein for approximately 109 kcal — one of the best protein-to-calorie ratios available in a commercial whey product. Use 1 to 2 servings per day as a high-satiety, muscle-protective meal component during a caloric deficit.

🏅 Sport Nutrition "Did you know?"

Whey protein isolate contains one of the highest naturally occurring concentrations of leucine of any protein source — typically 10 to 11g of leucine per 100g of protein. Leucine is not just one of three BCAAs: it is the specific amino acid that directly activates mTOR (mammalian target of rapamycin), the master switch for muscle protein synthesis. Research shows that a minimum leucine threshold of approximately 2 to 3g per serving is required to maximally stimulate mTOR. A single 30g serving of Isobolic easily exceeds this threshold, making every shake a complete and clinically effective anabolic stimulus.

Q1 — What is the difference between whey isolate and whey concentrate? Whey concentrate is the base form of whey protein, typically containing 70 to 80% protein alongside meaningful amounts of lactose, fat and other milk-derived components. Whey isolate undergoes additional filtration (cross-flow microfiltration or ion exchange) that removes almost all the lactose and fat, concentrating protein content to 85% or above. The result is a purer, cleaner product that is better tolerated by lactose-sensitive individuals and delivers more protein per gram of powder. Isobolic uses exclusively whey isolate, placing it in the premium tier of whey protein products.

Q2 — Is Isobolic suitable for people with lactose intolerance? Isobolic is a strong option for athletes with moderate lactose sensitivity, for two reasons. First, whey isolate filtration removes the vast majority of lactose from the protein source. Second, the addition of lactase enzyme in the formula actively breaks down any residual lactose present. That said, Isobolic is derived from cow's milk and still contains trace amounts of lactose. Individuals with severe lactose intolerance or a dairy allergy should consult their physician before use. Isobolic is not suitable for individuals with a clinical milk protein allergy.

Q3 — How many servings per day should I take? The optimal number of daily servings depends on your body weight, dietary protein intake from food, and training goals. The general recommendation is 1 to 3 servings per day. For most active individuals, 1 serving post-workout combined with a protein-rich diet provides sufficient supplemental protein. Athletes aiming for 2g/kg/day of total protein who struggle to reach this through food alone may benefit from 2 to 3 servings spread across the day: post-workout, between meals and optionally at breakfast.

Q4 — Can I use Isobolic during a cutting phase? Yes, and it is particularly well-suited to cutting. With approximately 109 kcal per 30g serving and 25.5g of protein, Isobolic delivers an exceptional protein-to-calorie ratio that makes it one of the most efficient tools for maintaining lean muscle mass during a caloric deficit. Its very low fat (0.37g) and sugar (0.53g) content ensures minimal impact on caloric budget while providing a high-satiety, muscle-protective protein source.

Q5 — What flavour should I choose? All 8 flavours are sweetened with sucralose and produced without aspartame. For athletes who prefer classic profiles: Chocolate and Vanilla are the most versatile for both shakes and cooking. For more indulgent options: Tiramisu, Salted Caramel and Double Chocolate Hazelnut are among the most distinctive flavours in the range. For fruit-forward options: Raspberry and Strawberry Banana work particularly well mixed with water or blended into smoothies. Cookies & Cream is a popular choice for athletes who enjoy a biscuit-like flavour profile. When in doubt, the 900g format is ideal for testing a new flavour before committing to the 1800g.
