Short answer: L-Arginine is involved in nitric oxide production, playing a role in supporting healthy circulation and blood flow throughout the body — the formula's most directly research-backed mechanism.
Why nitric oxide production is a specific, checkable mechanism
This names a well-established biological pathway — L-Arginine's role as a nitric oxide precursor is genuinely documented in broader nutritional research.
Why this connects directly to the formula's performance confidence claim
L-Arginine and Horny Goat Weed Extract are tied to healthy blood flow support, a foundational factor in performance confidence — the specific, stated logic behind this claim.
💡 Worth knowing: this same mechanism is the specific reason behind the formula's blood pressure and nitrate medication caution.
