Scitec BCAA 6400

🧬 4480mg of BCAAs per dose — the 2:1:1 leucine-dominant ratio

The 2:1:1 BCAA ratio (2 parts leucine per 1 part isoleucine and 1 part valine) is the most clinically studied BCAA ratio and the reference standard from which the majority of BCAA supplementation research derives its efficacy evidence. L-leucine at 2240mg per dose is the primary mTOR activator — the direct trigger for muscle protein synthesis at the cellular level. L-isoleucine (1120mg) supports glucose uptake into muscle cells and contributes to muscle glycogen replenishment. L-valine (1120mg) supports energy production during exercise and contributes to the anabolic environment alongside leucine and isoleucine.

💪 35% of essential amino acids in muscle — the most abundant EAA category

BCAAs constitute approximately 35% of the essential amino acids in skeletal muscle protein — a proportion that reflects their unique role not only as protein building blocks but as direct signals for muscle protein synthesis. Unlike most other essential amino acids, BCAAs (particularly leucine) are metabolised primarily in skeletal muscle rather than in the liver — meaning they reach muscle tissue directly after intestinal absorption, providing an immediate local stimulus for protein synthesis.

⚡ Flexible dosing — 1 to 3 doses per day

The recommended 1 to 3 daily doses protocol allows full customisation: 1 dose (5 tabs / 4480mg BCAAs) for maintenance or between-meal supplementation; 2 doses (10 tabs / 8960mg) for the standard pre + post training protocol; 3 doses (15 tabs / 13440mg) for athletes with very high training volumes, prolonged sessions or those in caloric deficit phases where BCAA supplementation for muscle mass preservation is particularly important.

💊 Tablet format — no gelatin — vegetarian and vegan compatible

BCAA 6400 uses a compressed tablet format with cellulose gel as the primary bulking agent — completely free from gelatin, shellac or any other animal-derived capsule or coating material. This makes it one of the few BCAA supplements in solid-dose format that is suitable for vegetarians and vegans. The amino acids themselves are produced through microbial fermentation rather than animal protein hydrolysis — completing the vegan compatibility of the formula.

🌿 Three-ingredient formula — maximum purity

The ingredient list contains three components: BCAA granular blend (70%), cellulose gel and anti-caking agents. No flavourings, no sweeteners, no artificial colours, no proprietary blend padding, no fillers beyond the minimum needed for tablet compression. For athletes who want to supplement BCAAs with complete ingredient transparency and without any unnecessary additives, BCAA 6400 provides the most minimal and pure solid-dose BCAA format available.

🎯 Goal guide

🏋️ Mass gain: 2 to 3 doses/day (10 to 15 tabs). Before and after training + optionally between meals. Maximises daily BCAA availability for mTOR signalling and muscle protein synthesis.

🔥 Weight loss / cutting: 2 to 3 doses/day. BCAA supplementation during caloric restriction is particularly effective at preserving muscle mass — leucine’s mTOR signalling continues to drive muscle protein synthesis even when total caloric intake is reduced, blunting muscle protein breakdown during the deficit.

⚖️ Endurance and body recomposition: 1 to 2 doses/day around training. BCAAs as a muscle preservation tool during long or frequent aerobic sessions where BCAA oxidation for energy is significant.

Serving suggestion

Take 5 tablets (1 dose) 1 to 3 times per day with a large glass of water. Standard protocol: consume 1 dose before training and 1 dose after training. For athletes taking 3 daily doses: add a third dose between meals (mid-morning or mid-afternoon) to maintain elevated plasma BCAA levels throughout the day.

Best times to take it

🏋️ Before training — pre-loading plasma BCAAs

Consuming 5 tablets 20 to 30 minutes before training pre-loads plasma leucine, providing elevated BCAA availability from the first set. Pre-training BCAA consumption reduces exercise-induced muscle protein breakdown during the session — particularly valuable for training in a fasted or semi-fasted state (morning sessions before breakfast).

🏋️ After training — post-workout anabolic window

5 tablets within 30 minutes of finishing training provides leucine for mTOR-driven muscle protein synthesis during the period of maximum anabolic sensitivity — when muscle insulin sensitivity, glycogen transporter activity and protein synthesis rate are all at their daily peak. The tablet format is particularly convenient post-training when preparing a protein shake is not immediately practical.

☀️ Between meals — inter-meal muscle preservation

On rest days or during long gaps between meals, 5 tablets provide 4480mg of BCAAs to maintain plasma BCAA levels and continuous mTOR stimulation between protein-containing meals. This is particularly relevant during caloric restriction phases where meal frequency or protein density may be reduced.

Q1 — What does “6400” mean in BCAA 6400 — is it 6400mg of BCAAs per dose?

No — each 5-tablet dose provides 4480mg of BCAAs, not 6400mg. The “6400” in the product name is a Scitec Nutrition historical naming convention for this product line, not a milligram declaration. At the maximum daily dose of 3 servings (15 tablets), total daily BCAA intake reaches 13440mg. The per-dose figure of 4480mg is the verified label figure. This naming convention is common in the sports nutrition category where product names often reflect cumulative or rounded figures rather than the precise dose per serving.

Q2 — Why take BCAAs as tablets rather than in a protein shake?

Protein shakes already contain naturally occurring BCAAs from their protein matrix (Scitec 100% Whey Protein Professional provides approximately 15.6g of BCAAs per 100g, or approximately 3.4g per 22g protein serving). BCAA tablets serve a different purpose: they provide a rapid, highly concentrated dose of free-form BCAAs in solid format that can be taken at any moment — before training, during a workout (swallowed with water mid-session), between meals or immediately after training — without the preparation time and caloric contribution of a protein shake. For athletes who are already consuming 1 to 2 protein shakes per day and want additional targeted BCAA dosing at specific moments, BCAA 6400 tablets provide the most convenient and minimal format available.

Q3 — Is BCAA 6400 suitable for vegans?

Yes. The amino acids in BCAA 6400 (L-leucine, L-isoleucine, L-valine) are produced through microbial fermentation using plant-based fermentation substrates — not through animal protein hydrolysis. The tablet bulking agent (cellulose gel) is plant-derived. No gelatin, no shellac, no animal-derived ingredients of any kind are present in the formula. BCAA 6400 is one of the few solid-dose BCAA supplements that is genuinely suitable for vegans.

Q4 — How does BCAA 6400 tablets compare to BCAA + Glutamine Xpress powder?

The two products are complementary rather than competing. BCAA + Glutamine Xpress powder provides 2500mg BCAAs + 2500mg L-glutamine per 6g serving, mixed with water as a flavoured intra-workout drink — the powder format is ideal for continuous sipping during training. BCAA 6400 tablets provide 4480mg BCAAs per 5-tablet dose with no glutamine, in a solid format that can be swallowed quickly at any moment without preparation. For athletes who want flavoured intra-workout amino acid hydration, BCAA + Glutamine Xpress is the appropriate choice. For athletes who want a rapid, convenient unflavored BCAA dose at targeted moments (before training, at work, before sleep during cutting phases), BCAA 6400 tablets are the more practical format.

Q5 — Which format should I choose — 125 or 375 tablets?

The formula is identical. The 125-tablet format (25 daily doses at 5 tabs) provides approximately 12 to 25 days of supply depending on daily dose (2 or 1 dose/day). The 375-tablet format (75 daily doses at 5 tabs) provides approximately 37 days at 2 doses/day or 75 days at 1 dose/day — and is significantly more economical per tablet. For athletes who have established BCAA 6400 as a consistent daily supplement, the 375-tablet format is the clear value choice.
