Short answer: L-Arginine Alpha-Ketoglutarate is a stabilized arginine compound studied for supporting circulation and consistent nitric oxide availability throughout the day.
Why "stabilized" is a specific, checkable formulation detail
This describes a bound form of arginine designed for more consistent behavior in the body, distinct from standard L-Arginine HCl's more direct delivery.
Why this ingredient is the third, less-discussed amino acid in the blend
L-Arginine HCl and L-Citrulline Malate get more individual attention in the formula's own materials — this stabilized compound rounds out the blend as a third, complementary contributor.
💡 Worth knowing: like the other two amino acids, this ingredient's exact individual milligram amount within the 500 mg blend is not separately disclosed.
