Short answer: L-Arginine Alpha-Ketoglutarate (AAKG) pairs arginine with alpha-ketoglutarate, included to support more consistent nitric oxide availability throughout the day.
Why "two forms of arginine, one pathway" describes this specific pairing
L-Arginine HCl plus AAKG both feed nitric oxide production, from slightly different angles — a genuinely distinct mechanism worth understanding alongside the L-Citrulline conversion pathway.
Why this compound is named with its specific abbreviation
AAKG is used directly alongside the full chemical name — worth recognizing this specific abbreviation if you're comparing ingredient lists across similar products.
💡 Worth knowing: this is one of three named amino acid compounds making up the formula's full 500mg blend.
