This formula's own materials mention reducing arterial stiffness as a benefit area — worth understanding what that specific vascular property actually means.
Arterial stiffness describes how flexible or rigid the walls of your arteries are — more flexible vessels can expand and contract more easily with each heartbeat, while stiffer vessels resist that natural expansion, which is a factor in overall vascular health.
Nitric oxide's vessel-relaxing signal is one factor associated with maintaining vascular flexibility over time — worth reading this formula's "reduces arterial stiffness" claim as connected to that same underlying nitric-oxide mechanism, not a separate, independent effect.
