Short answer: L-Arginine (base, 200mg) is an amino acid the body uses to produce nitric oxide, while L-Arginine AKG 2:1 Extract (200mg) is L-Arginine bound to alpha-ketoglutarate, theorized to improve absorption.
Why two forms of the same amino acid appear together
The AKG-bound form is theorized to improve absorption and extend the nitric oxide support window versus standard L-Arginine — a specific, stated reason for including both.
Why exact milligram amounts matter for evaluating this pairing
MindCept's combined arginine total is 400mg — a specific, disclosed figure worth comparing directly against research doses, unlike a proprietary blend that hides this total.
💡 Worth knowing: most clinical research on L-Arginine for vascular function uses doses in the 3,000–9,000mg range — a direct, honest gap worth understanding.
