What is Scitec Nutrition AAKG?
Scitec Nutrition AAKG is a concentrated arginine alpha-ketoglutarate supplement from Scitec Nutrition in a simple, minimal capsule formula. Each 4-capsule daily dose delivers 3200mg of L-arginine alpha-ketoglutarate — of which 2152mg is pure L-arginine — the primary substrate for nitric oxide (NO) production in vascular endothelial cells.
AAKG is a salt form of L-arginine where the amino acid is bound to alpha-ketoglutarate — a key intermediate in the Krebs cycle (the cellular energy production pathway). This molecular pairing provides two distinct functional mechanisms. The L-arginine component is the sole precursor to nitric oxide synthase (NOS)-driven NO production — elevated circulating arginine from supplementation increases NO availability, relaxing and dilating blood vessel walls (vasodilation) and increasing blood flow to active muscles during training. The alpha-ketoglutarate component is itself a functional Krebs cycle intermediate that participates in cellular energy production biochemistry and acts as one of the most important nitrogen transport agents in metabolic pathways.
The formula is deliberately minimal: 86% AAKG, gelatin capsule shell with shellac glazing, and magnesium stearate as an anti-caking agent. No unnecessary fillers, no flavourings, no colourings beyond the iron oxide in the capsule shell.
100 capsules providing 25 servings at the recommended 4-capsule daily dose.

💉 3200mg of AAKG — 2152mg of pure L-arginine per daily dose
Each 4-capsule daily serving provides 3200mg of L-arginine alpha-ketoglutarate, delivering 2152mg of pure L-arginine — a meaningful arginine supplementation dose in the range studied in research on nitric oxide-mediated vasodilation and training performance. L-arginine is the direct substrate for nitric oxide synthase (NOS) — the enzyme that produces NO from arginine in endothelial cells — making AAKG supplementation a direct intervention in the NO production pathway.
⚡ Nitric oxide (NO) production — vascular pump and blood flow
L-arginine is the sole endogenous precursor to NO. Elevated circulating arginine from supplementation increases NOS enzyme activity, producing more NO in vascular endothelial cells. This NO relaxes vascular smooth muscle and widens blood vessel diameter (vasodilation), increasing blood flow, oxygen delivery and nutrient supply to working muscles during training. The subjective manifestation of this vasodilation is the characteristic muscle pump — the sensation of fullness and vascularity in trained muscles during and after a set.
🔬 Alpha-ketoglutarate — dual Krebs cycle and nitrogen transport function
The alpha-ketoglutarate component of AAKG is not merely a passive binding agent — it is a biochemically active compound. As an essential Krebs cycle intermediate, alpha-ketoglutarate participates directly in cellular energy production. As one of the most important nitrogen transport agents in metabolic pathways, it plays a role in amino acid metabolism and the transfer of nitrogen between tissues. Together, the arginine and alpha-ketoglutarate components provide a more complete metabolic mechanism than free-form L-arginine alone.
💊 86% AAKG — minimal, clean formula
At 86% AAKG by weight, the Scitec AAKG formula provides a high active ingredient concentration with a minimal excipient profile. The only non-active components are the gelatin capsule shell (with shellac glazing, iron oxide colouring and pH regulators for capsule integrity) and magnesium stearate as a flow agent. No proprietary blend padding, no unnecessary additives.
🎯 Goal guide
🏋️ Mass gain: 4 capsules/day pre-workout. NO-mediated blood flow maximises nutrient delivery to muscle tissue under progressive overload — the training pump as a functional indicator of enhanced muscular blood supply.
🔥 Weight loss / cutting: 4 capsules/day. Supports training quality and vascular pump during caloric restriction, maintaining training intensity when overall energy availability is reduced.
⚖️ Strength and endurance: 4 capsules/day pre-workout. Pre-workout arginine loading for sustained blood flow and pump throughout the session.
Serving suggestion
Take 4 capsules per day with a large glass of water. Consume before training for optimal pre-workout timing. Do not exceed the recommended daily dose. Keep out of reach of children. Use as part of a healthy and varied diet and lifestyle — not as a substitute for a balanced diet.
Best times to take it
🏋️ 30 to 60 minutes before training (primary recommendation)
L-arginine reaches peak plasma concentration approximately 60 to 90 minutes after oral intake. Taking 4 capsules 30 to 60 minutes before training ensures peak arginine availability during the training session, maximising the NO-mediated vasodilation effect and the associated pump and blood flow benefits during the period of highest physical demand.
☀️ On an empty stomach for maximum absorption
Arginine absorption is more efficient in a fasted state — competing amino acids from a meal reduce the intestinal transport capacity available for arginine. Taking AAKG on an empty stomach or at least 30 minutes before a meal improves the effective dose that reaches circulation compared to taking it with food.
🌙 Before sleep (alternative — growth hormone support)
L-arginine supplementation before sleep may support the natural growth hormone secretion peak that occurs during deep sleep. Some athletes split their dose between pre-workout and pre-sleep for dual training performance and overnight recovery application.

Q1 — What is AAKG and how does it differ from free-form L-arginine?
AAKG (arginine alpha-ketoglutarate) is a salt formed by combining L-arginine with alpha-ketoglutarate — a key intermediate in the Krebs cycle (cellular energy metabolism). The AAKG form offers two advantages over plain L-arginine. First, the alpha-ketoglutarate salt form is absorbed more efficiently through the intestinal wall, reducing the gastrointestinal discomfort that can occur with high-dose free-form L-arginine supplementation. Second, the alpha-ketoglutarate component is itself biochemically active — as an essential Krebs cycle intermediate and nitrogen transport agent — providing an additional metabolic dimension beyond pure arginine’s NO precursor role.
Q2 — How does Scitec AAKG compare to Olimp AAKG 1250 Mega Caps?
Both products deliver AAKG in capsule form, but with different dosing architectures. Olimp AAKG 1250 Mega Caps provides 3750mg AAKG (2438mg pure L-arginine) per 3-capsule dose — a slightly higher AAKG dose per serving in a Mega Caps format requiring only 3 capsules. Scitec AAKG provides 3200mg AAKG (2152mg pure L-arginine) per 4-capsule dose. Olimp’s 120-capsule format provides 40 daily doses vs Scitec’s 100-capsule format providing 25 daily doses. For athletes who prioritise the highest AAKG dose per serving with the fewest capsules, Olimp Mega Caps is the superior choice. For athletes who want a more accessible entry point to AAKG supplementation at a lower per-unit cost, Scitec AAKG is a straightforward alternative.
Q3 — Can Scitec AAKG be combined with the Scitec 100% Whey Protein Professional or other supplements in the catalogue?
Yes. AAKG capsules have no interactions with any other supplement in the Scitec range or the broader catalogue. The most natural combination is AAKG taken 30 to 60 minutes before training, followed by 100% Whey Protein Professional or 100% Whey Isolate immediately after training — AAKG handles the pre-workout vasodilation and NO stimulus, the whey protein handles the post-workout amino acid delivery. For athletes who also use GSN Vaso Pump (L-citrulline DL malate based), AAKG and citrulline work via the same NO pathway but at different entry points — their combination produces a compounded vasodilation effect.
Q4 — Is Scitec AAKG suitable for vegetarians?
No. The capsule shell contains gelatin (bovine or porcine origin) and shellac — a glazing agent derived from the lac resin secreted by the lac insect (Kerria lacca). Both are animal-derived ingredients that make the product unsuitable for vegetarians and vegans. The AAKG active ingredient itself is synthetic and vegan-compatible — but the capsule shell is not. Athletes who require a vegetarian or vegan-compatible AAKG product would need to source an alternative format (unflavored powder or HPMC capsule).
Q5 — With only 25 days of supply per pack, how should I manage purchasing?
At 4 capsules per day, the 100-capsule pack provides 25 days — approximately 3.5 weeks. For athletes who use AAKG continuously as part of their pre-workout routine, purchasing a new pack before the current one runs out ensures uninterrupted daily supplementation. Many athletes use AAKG specifically during training blocks rather than continuously year-round — in which case the 100-capsule format is well-aligned with a structured 3 to 4-week pre-workout optimisation phase.
