Addict Intrafuse BCAA + Glutamine Powder

How Intrafuse BCAA + Glutamine by Addict Sport Nutrition supports your objectives

💪 8000mg of glutamine per serving for recovery and anti-catabolism Glutamine is the amino acid most rapidly depleted during intense exercise. Low plasma and muscle glutamine levels correlate directly with slower recovery, impaired immune function and increased muscle catabolism. The 8000mg per serving provides a substantial repletion dose that helps restore muscle glutamine concentrations after training, maintaining the anabolic environment needed for muscle repair and growth.

🧬 BCAA 2:1:1 at 6800mg — muscle protein synthesis and energy provision The 3400mg of leucine per serving activates mTOR-driven muscle protein synthesis, while isoleucine (1700mg) supports glucose uptake during exercise and valine (1700mg) contributes to nitrogen balance and energy production during effort. The 2:1:1 ratio is the most studied BCAA ratio in sports science and the one most consistently associated with performance and recovery benefits across a broad range of training contexts.

🔄 Synergistic anti-catabolic and anabolic action The BCAA and glutamine components of Intrafuse operate synergistically: both independently stimulate muscle protein synthesis and inhibit muscle protein breakdown, but under training stress they interact further, with BCAAs contributing to glutamine biosynthesis in muscle tissue. This dual mechanism provides broader and more sustained anti-catabolic and anabolic protection than a BCAA-only or glutamine-only product.

⚡ Fast absorption — active within approximately 20 minutes The combination of free-form amino acids with dextrose and fructose as carbohydrate carriers accelerates intestinal absorption. Free-form amino acids do not require digestion and enter the bloodstream directly, with peak plasma levels reached in approximately 20 minutes. The small carbohydrate contribution (3g of sugar per serving) provides a mild insulin stimulus that further enhances amino acid uptake into muscle tissue.

🛡️ Immune system and gut wall support Beyond its muscle recovery role, glutamine is a primary fuel source for the cells lining the intestinal wall (enterocytes) and for immune cells (lymphocytes). Regular supplementation helps maintain gut barrier integrity and supports immune function during high training load periods, a particularly relevant benefit during intense training blocks when illness risk is elevated.

🎯 Goal guide

🏋️ Mass gain: 1 serving during or post-workout. Maximises anabolic and anti-catabolic conditions under caloric surplus training.

🔥 Weight loss / cutting: 1 serving during training. Protects muscle mass and supports immunity during caloric restriction.

⚖️ Body recomposition: 1 serving post-workout. Glutamine and BCAA synergy for sustained recovery under high-frequency training.

Serving suggestion

Mix half a scoop (approximately 20g) in 180 to 300ml of cold water. Shake well in a shaker bottle until fully dissolved. Leave to stand for 30 seconds before drinking. Consume before, during or after training. Do not exceed the recommended daily serving. Not recommended for individuals under 18, pregnant or breastfeeding women, or people on medical treatment.

Best times to enjoy it

🏋️ During training (intra-workout) Sipping Intrafuse throughout a training session maintains continuous BCAA and glutamine availability during the effort, simultaneously providing anti-catabolic amino acid protection and fuelling ongoing muscle protein synthesis signalling.

⚡ Immediately post-workout The 20-minute absorption window makes Intrafuse particularly effective when consumed immediately after training, providing rapid glutamine replenishment and a leucine-driven mTOR stimulus at peak anabolic sensitivity.

🌅 Pre-workout (fasted training) For athletes who train in a fasted state, taking Intrafuse before the session protects muscle protein from the accelerated catabolism that occurs when glycogen and amino acid reserves are depleted.

🌙 Before sleep (glutamine protocol) A serving before sleep is particularly relevant for athletes over 30, where overnight recovery benefits most from sustained glutamine availability. The 8000mg per serving aligns with the 5 to 10g pre-sleep glutamine doses studied in sports science research.

Daily protein target reminder

Intrafuse is an amino acid recovery supplement, not a substitute for total daily protein intake from complete food sources. 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.

Goal-specific guidance

For mass gain: Use Intrafuse intra or post-workout to optimise the anabolic and anti-catabolic amino acid environment during and after each session. Combine with a complete protein source post-workout for full amino acid coverage. The glutamine component also protects intestinal wall integrity during high training volumes, improving nutrient absorption from post-workout meals and shakes.

For weight loss and cutting: During a caloric deficit, both BCAA and glutamine levels decline more rapidly, increasing muscle catabolism risk and immune vulnerability. A daily serving of Intrafuse maintains amino acid availability for muscle protection at a very modest caloric cost, making it one of the highest-value supplements for athletes in a cutting phase.

🏅 Sport Nutrition "Did you know?"

Glutamine has a unique relationship with growth hormone (GH) that is rarely discussed in mainstream sports nutrition. Studies have shown that oral glutamine supplementation — even at relatively low doses — can produce a significant and measurable increase in plasma GH levels within 90 minutes of consumption. At the 8g dose in each Intrafuse serving, this effect is particularly relevant for athletes over 30, where resting GH secretion is already declining. The combination of BCAAs and glutamine taken before sleep may contribute to a more favourable hormonal environment for overnight recovery and body composition over time.

Bottle duration guide

Q1 — Why combine BCAAs and glutamine in the same product? BCAAs and glutamine are individually among the most studied amino acid supplements in sports nutrition, and their combination produces effects greater than either alone. Both compounds independently stimulate muscle protein synthesis and inhibit muscle catabolism. Under training stress they interact further: BCAAs — and leucine in particular — can contribute to glutamine biosynthesis within muscle tissue, meaning that taking both together creates a more complete and self-reinforcing amino acid recovery environment. Low plasma glutamine is also a recognised marker of overtraining, and BCAAs help prevent this decline by contributing to glutamine production.

Q2 — What is the difference between Intrafuse and the EAA+BCAA formula from the same brand? Both products contain BCAAs, but they serve different purposes. Intrafuse pairs BCAAs with a high dose of glutamine (8000mg) for a recovery-focused formula that prioritises anti-catabolism, immune support and gut health alongside muscle protein synthesis. EAA+BCAA pairs BCAAs with the six remaining essential amino acids for a formula that prioritises complete muscle protein synthesis across all nine EAAs. Intrafuse is the better choice for athletes focused on recovery quality and training frequency management. EAA+BCAA is the better choice for athletes who want a complete essential amino acid profile during training.

Q3 — Is Intrafuse suitable for vegans? Yes. The amino acids in Intrafuse (L-glutamine, L-leucine, L-isoleucine, L-valine) are produced through a fermentation process using plant-derived substrates, making the formula free of animal-derived ingredients. It is suitable for vegan and vegetarian athletes. The manufacturing facility processes products containing milk, eggs and other allergens, so cross-contamination risk should be verified on the current product label.

Q4 — Can I take Intrafuse before sleep as a recovery supplement? Yes, and this is a particularly evidence-supported timing for the glutamine component. Research has shown that glutamine supplementation can stimulate growth hormone secretion, which peaks during the first hours of sleep. An additional pre-sleep serving is a protocol recommended specifically for athletes over 30, where overnight GH secretion and muscle recovery are most in need of support. The 8000mg per serving aligns well with the doses studied in this context.

Q5 — How many servings does the 500g bottle provide and how long does it last? At 20g per serving, the 500g bottle provides exactly 25 servings. At one serving per training day, this represents approximately 4 to 6 weeks of use for athletes training 4 to 6 sessions per week, or up to 8 weeks for those training 3 times per week.
