L-Arginine AKG
L‑Arginine Alpha‑Ketoglutarate (AKG)
Snapshot
L‑Arginine AKG is a salt of the amino acid L‑arginine and alpha‑ketoglutarate, designed to enhance nitric oxide production, energy metabolism, and exercise performance.
What is L‑Arginine AKG?
L‑Arginine AKG combines two molecules—L‑arginine and alpha‑ketoglutarate (a key Krebs cycle intermediate)—to support both nitric oxide synthesis (via arginine) and cellular energy production (via AKG).
Where It Comes From
This compound is synthesized by reacting L‑arginine with alpha‑ketoglutaric acid under controlled conditions, then crystallized into a stable, bioavailable form suitable for capsule or powder supplements.
Key Nutrients & Compounds
L‑Arginine AKG supplies the free L‑arginine isomer and alpha‑ketoglutarate in an equimolar ratio. Arginine serves as a nitric oxide precursor, while AKG enters the Krebs cycle to support ATP generation and nitrogen disposal.
Health Benefits
Arginine in the complex promotes vasodilation and blood flow, enhancing oxygen and nutrient delivery during exercise. AKG supports mitochondrial energy production, aids ammonia clearance via the urea cycle, and may reduce muscle protein breakdown.
Recommended Dosage
Typical doses range from 3 to 6 grams of L‑Arginine AKG per day (providing approximately 1.5–3 g arginine and 1.5–3 g AKG), divided into two servings, often taken before workouts.
How to Use It
Mix powder into water or a sports drink and consume 30–45 minutes prior to exercise. Capsules can be taken similarly, ensuring adequate hydration.
Who Should Use It?
Ideal for athletes and active individuals seeking improved blood flow, endurance, and recovery. It benefits those engaged in high‑intensity or prolonged exercise and anyone aiming to support cellular energy metabolism.
Possible Interactions or Cautions
High doses may cause gastrointestinal discomfort. L‑Arginine AKG can interact with blood‑pressure medications and erectile dysfunction drugs by potentiating vasodilatory effects. Individuals with kidney or liver impairment should consult a healthcare provider.
Final Thoughts
L‑Arginine AKG combines the vascular benefits of arginine with the metabolic support of AKG, offering a synergistic supplement for performance and recovery. When dosed appropriately around exercise, it can enhance circulation, energy production, and muscle preservation.
