Addict Native Micellar Casein

How Caseine Native by Addict Sport Nutrition supports your objectives

⏳ Up to 7 hours of sustained amino acid release Micellar casein forms a gel-like clot in the stomach's acidic environment, which is then digested slowly and progressively over 4 to 7 hours. This produces a steady, sustained drip of amino acids into the bloodstream — in sharp contrast to whey, which is absorbed rapidly in 1 to 2 hours and then falls away. For overnight use and long inter-meal periods, this sustained delivery is physiologically more appropriate and more protective of muscle mass than any fast-digesting protein source.

🧬 Native, non-denatured micellar casein — maximum biological value The native extraction process preserves the intact micellar structure of the casein protein and all of its natural bioactive peptides. Non-denatured casein has a higher biological value than denatured caseinates or acid-precipitated casein, meaning a greater proportion of each gram consumed is actually available for muscle protein synthesis. This is the same fundamental quality principle behind native whey — applied here to the slow-digesting casein fraction.

🛡️ Superior anti-catabolic protection during overnight fasting During sleep, the body goes 7 to 8 hours without food. In this period, circulating amino acid levels gradually decline, creating an increasingly catabolic hormonal environment. A single serving of micellar casein before sleep provides the sustained amino acid delivery needed to blunt this overnight catabolism, protecting hard-earned lean muscle mass throughout the entire sleep period. Research confirms that casein provides a superior anti-catabolic effect compared to whey proteins specifically during this extended overnight window.

💪 L-glutamine and acetyl L-glutamine for enhanced recovery The addition of L-glutamine and acetyl L-glutamine to the formula amplifies its recovery properties. Glutamine is the most rapidly depleted amino acid following intense exercise and is a critical fuel for immune cells and gut enterocytes. Acetyl L-glutamine — the more bioavailable acetylated form — crosses cell membranes more efficiently, providing faster availability where it matters most. Together, they support muscle repair, immune resilience and gut integrity during the overnight recovery window.

🍃 Positive nitrogen balance — the foundation of muscle growth Research demonstrates that micellar casein maintains a positive nitrogen balance for longer than any other protein type. Positive nitrogen balance (more nitrogen retained than excreted) is the biochemical definition of net muscle protein accretion. For athletes in a mass-gaining or maintenance phase, consistently achieving positive nitrogen balance overnight is one of the most impactful nutritional strategies for long-term lean muscle accumulation.

🎯 Goal guide

🏋️ Mass gain: 1 serving before sleep. Maximises overnight positive nitrogen balance and amino acid availability during the body's primary anabolic window.

🔥 Weight loss / cutting: 1 serving before sleep. High-satiety, slow-digesting protein that prevents overnight catabolism during caloric restriction.

⚖️ Body recomposition: 1 serving before sleep. Anti-catabolic protection combined with enhanced recovery compounds overnight.

Serving suggestion

Mix 1 level scoop (approximately 30g) with 200 to 300ml of cold water or milk. Shake well in a shaker bottle until fully dissolved. For a thicker, pudding-like texture — a popular preparation for casein — use less liquid (100 to 150ml) and stir rather than shake. Casein's micellar structure thickens significantly at lower liquid volumes, creating a high-protein dessert consistency that many athletes prefer as a satisfying evening meal.

Best times to enjoy it

🌙 Before sleep (primary window) The optimal and most evidence-supported timing: consume 30 to 40 minutes before going to bed. Micellar casein reaches the stomach before sleep onset and begins forming the gel matrix that will release amino acids steadily throughout the 7 to 8 hours of overnight fasting.

🥗 Between meals during long periods without food For athletes who go more than 3 hours between meals, a casein shake bridges the inter-meal gap more effectively than whey, providing sustained amino acid availability that prevents the muscle catabolism that accumulates during extended fasting periods.

✈️ During travel, long working days or unpredictable schedules Any situation where regular meal timing is compromised and long periods without food are expected. Casein's slow-release profile makes it uniquely resilient to unpredictable daily schedules — a single serving protects muscle mass for up to 7 hours regardless of when the next meal arrives.

🏋️ In combination with whey post-workout (advanced protocol) For athletes who train in the evening, combining a post-workout whey shake (fast amino acid spike) with a pre-sleep casein shake (sustained overnight delivery) creates a comprehensive multi-phase protein strategy that addresses both the immediate post-exercise anabolic window and the overnight anti-catabolic window simultaneously.

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 30g serving of Caseine Native contributes approximately 25.5g toward this daily target. For vegan athletes, targeting the upper end (1.8 to 2.2g/kg) is advised.

*Caseine Native is typically used as a single daily serving before sleep alongside a complete daytime protein strategy.

Goal-specific guidance

For mass gain: Use Caseine Native consistently every night as the final nutritional act of the day. The overnight period represents the longest fasting window in every athlete's schedule — and the period where the body's natural anabolic hormones (GH, IGF-1) are at their highest. Providing a sustained amino acid supply during this window ensures that muscle protein synthesis, which peaks during sleep, is not limited by amino acid availability. Pair with Anabolic Whey Complex or Isobolic throughout the day for complete daily protein coverage.

For weight loss and cutting: Caseine Native is one of the most valuable supplements during a caloric deficit phase for two reasons. First, it is highly satiating — the slow gastric emptying produced by casein's gel formation reduces night-time hunger and prevents overeating at the next meal. Second, it specifically prevents the accelerated muscle catabolism that occurs overnight during a caloric deficit, helping preserve lean muscle mass while the body loses fat. A single pre-sleep serving adds approximately 110 kcal and 25.5g of protein — a highly efficient caloric investment for muscle protection.

🏅 Sport Nutrition "Did you know?"

A landmark study by Res et al. (2012) demonstrated for the first time that protein ingested immediately before sleep was effectively digested and absorbed during the overnight period, and that this protein intake directly stimulated muscle protein synthesis during sleep — increasing whole-body protein balance by approximately 22% compared to a placebo group. This study established the pre-sleep protein protocol as a legitimate and evidence-based strategy for maximising overnight muscle recovery and growth, and specifically validated micellar casein as the optimal protein source for this application due to its sustained release profile.

Nutritional values per serving

Format and serving guide

Q1 — What is the difference between Caseine Native and standard casein supplements? Standard casein supplements are typically made from micellar casein treated with alkali (sodium caseinate or calcium caseinate), a process that denatures the protein and reduces its biological value. Caseine Native uses cold microfiltration to extract micellar casein from fresh skimmed milk without denaturation, preserving the intact micellar structure and all naturally occurring bioactive peptides. This native extraction method produces a protein with a higher biological value and a more complete nutritional profile than acid-precipitated or alkali-treated caseinates.

Q2 — Why should I take casein before sleep rather than whey? Whey protein is rapidly digested and absorbed, with amino acid levels peaking within 60 to 90 minutes and returning to baseline within 3 to 4 hours. During an overnight fast of 7 to 8 hours, a pre-sleep whey shake would be fully absorbed within the first few hours, leaving the remaining 4 to 5 hours of sleep without amino acid support. Micellar casein's gel-forming mechanism in the stomach delays digestion and sustains amino acid release for up to 7 hours — providing coverage for the entire overnight fasting period. Research has confirmed that this sustained release produces superior anti-catabolic effects during sleep compared to whey.

Q3 — Can I use Caseine Native as my main protein source throughout the day? Caseine Native can technically be consumed at any time of day, but its slow absorption profile makes it less optimal as a post-workout protein (where faster amino acid delivery is preferred). For most athletes, the ideal protocol is to use a fast-digesting whey protein (Isobolic, Anabolic Whey Complex) throughout the day and post-workout, and reserve Caseine Native for the pre-sleep serving where its sustained release profile provides the most specific and irreplaceable benefit.

Q4 — What are the benefits of the added L-glutamine and acetyl L-glutamine? L-glutamine is the most abundant amino acid in skeletal muscle and the primary fuel for immune cells and intestinal wall cells (enterocytes). It is rapidly depleted during intense exercise, making supplementation particularly relevant for athletes with high training volumes. Acetyl L-glutamine is a more bioavailable form that crosses cell membranes more efficiently, providing enhanced delivery to muscle and immune tissue. Together, they amplify the recovery and anti-catabolic effects of the casein protein matrix — making this formula more comprehensive than a pure casein product.

Q5 — Is Caseine Native suitable for people with lactose intolerance? Micellar casein contains very low levels of lactose, as the microfiltration process that produces it separates casein from the whey fraction (which carries most of the lactose). Many individuals with mild lactose sensitivity tolerate micellar casein well. However, it is derived from cow's milk and is not suitable for individuals with a milk protein allergy. Athletes with confirmed lactose intolerance should patch-test with a small serving and consult their physician before regular use.
